			<content:encoded><![CDATA[<p>Starting from his miraculous year of 1905, Einstein has dominated physics with his astonishing insights on space and time, and on mass and gravity. True, there have been other physicists who, with their own brilliance, have shaped and moved modern physics in directions that even Einstein couldn&#8217;t have foreseen; and I don&#8217;t mean to trivialize neither their intellectual achievements nor our giant leaps in physics and technology. But all of modern physics, even the bizarre reality of quantum mechanics, which Einstein himself couldn&#8217;t quite come to terms with, is built on his insights. It is on his shoulders that those who came after him stood for over a century now.</p>

<p>One of the brighter ones among those who came after Einstein cautioned us to guard against our blind faith in the infallibility of old masters. Taking my cue from that insight, I, for one, think that Einstein&#8217;s century is behind us now. I know, coming from a non-practicing physicist, who sold his soul to the finance industry, this declaration sounds crazy. Delusional even. But I do have my reasons to see Einstein&#8217;s ideas go.</p>
<p><img src="http://www.thulasidas.com/img/grb-small.gif" alt="[animation]" class="alignleft" />Let&#8217;s start with this picture of a dot flying along a straight line (on the ceiling, so to speak). You are standing at the centre of the line in the bottom (on the floor, that is). If the dot was moving faster than light, how would you see it? Well, you wouldn&#8217;t see anything at all until the first ray of light from the dot reaches you. As the animation shows, the first ray will reach you when the dot is somewhere almost directly above you. The next rays you would see actually come from two different points in the line of flight of the dot &#8212; one before the first point, and one after. Thus, the way you would see it is, incredible as it may seem to you at first, as one dot appearing out of nowhere and then splitting and moving rather symmetrically away from that point. (It is just that the dot is flying so fast that by the time you get to see it, it is already gone past you, and the rays from both behind and ahead reach you at the same instant in time.Hope that statement makes it clearer, rather than more confusing.).</p>
<p><img src="http://www.thulasidas.com/img/ijmpd-figure3.png" alt="[animation]" class="alignright" />Why did I start with this animation of how the illusion of a symmetric object can happen? Well, we see a lot of active symmetric structures in the universe. For instance, look at this picture of Cygnus A. There is a &#8220;core&#8221; from which seem to emanate &#8220;features&#8221; that float away to the &#8220;lobes.&#8221; Doesn&#8217;t it look remarkably similar to what we would see based on the animation above? There are other examples in which some feature points or knots seem to move away from the core where they first appear at. We could come up with a clever model based on superluminality and how it would create illusionary symmetric objects in the heavens. We could, but nobody would believe us &#8212; because of Einstein. I know this &#8212; I tried to get my old physicist friends to consider this model. The response is always some variant of this, &#8220;Interesting, but it cannot work. It violates Lorentz invariance, doesn&#8217;t it?&#8221; LV being physics talk for Einstein&#8217;s insistence that nothing should go faster than light. Now that neutrinos can violate LV, why not me?</p>
<p>Of course, if it was only a qualitative agreement between symmetric shapes and superluminal celestial objects, my physics friends are right in ignoring me. There is much more. The lobes in Cygnus A, for instance, emit radiation in the radio frequency range. In fact, the sky as seen from a radio telescope looks materially different from what we see from an optical telescope. I could show that the spectral evolution of the radiation from this superluminal object fitted nicely with AGNs and another class of astrophysical phenomena, hitherto considered unrelated, called gamma ray bursts. In fact, I managed to publish this model a while ago under the title, &#8220;<a href="http://www.thulasidas.com/2008-11/are-radio-sources-and-gamma-ray-bursts-luminal-booms.htm" title="Superluminality in Astrophysics">Are Radio Sources and Gamma Ray Bursts Luminal Booms?</a>&#8220;.</p>
<p>You see, I need superluminality. Einstein being wrong is a pre-requisite of my being right. So it is the most respected scientist ever vs. yours faithfully, a blogger of the unreal kind. You do the math. <img src='http://www.thulasidas.com/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' /> </p>
<p>Such long odds, however, have never discouraged me, and I always rush in where the wiser angels fear to tread. So let me point out a couple of inconsistencies in SR. The derivation of the theory starts off by pointing out the effects of light travel time in time measurements. And later on in the theory, the distortions due to light travel time effects become part of the properties of space and time. (In fact, light travel time effects will make it impossible to have a superluminal dot on a ceiling, as in my animation above &#8212; not even a virtual one, where you take a laser pointer and turn it fast enough that the laser dot on the ceiling would move faster than light. It won&#8217;t.) But, as the theory is understood and practiced now, the light travel time effects are to be applied on top of the space and time distortions (which were due to the light travel time effects to begin with)! Physicists turn a blind eye to this glaring inconstancy because SR &#8220;works&#8221; &#8212; as I made very clear in my previous post in this series.</p>
<p>Another philosophical problem with the theory is that it is not testable. I know, I alluded to a large body of proof in its favor, but fundamentally, the special theory of relativity makes predictions about a uniformly moving frame of reference in the absence of gravity. There is no such thing. Even if there was, in order to verify the predictions (that a moving clock runs slower as in the twin paradox, for instance), you have to have acceleration somewhere in the verification process. Two clocks will have to come back to the same point to compare time. The moment you do that, at least one of the clocks has accelerated, and the proponents of the theory would say, &#8220;Ah, there is no problem here, the symmetry between the clocks is broken because of the acceleration.&#8221; People have argued back and forth about such thought experiments for an entire century, so I don&#8217;t want to get into it. I just want to point out that theory by itself is untestable, which should also mean that it is unprovable. Now that there is direct experimental evidence against the theory, may be people will take a closer look at these inconsistencies and decide that it is time to say bye-bye to Einstein.</p>

		<description><![CDATA[I just finished writing my first Mac application because I had a specific problem (duplicate imports of photos into my iPhoto Library) to solve. This problem may be fairly common, so I'm making it available (all right, selling it) to the general public. Here is a summary of what it does and how to get it. <a href="http://www.thulasidas.com/2011-12/how-to-avoid-duplicate-imports-in-iphoto.htm">Continue reading <span class="meta-nav">&#8594;</span></a>]]></description>
			<content:encoded><![CDATA[<p>For the budding photographer in you, iPhoto is a godsend. It is the iLife photo organization program that comes pre-installed on your swanky new iMac or Mac Book Air. In fact, I would go as far as to say that iPhoto is one of the main reasons to switch to a Mac. I know, there are alternatives, but for seamless integration and smooth-as-silk workflow, iPhoto reigns supreme.</p>
<p><a href="http://buy.ads-ez.com/iPhotoTagger"  target="_blank"><img class="alignleft" title="iPhotoTagger" src="/img/iPhotoTagger.png" alt="iPhotoTagger" /></a>But (ah, there is always a &#8220;but&#8221;), the workflow in iPhoto can create a problem for some. It expects you to shoot pictures, connect your camera to your Mac, move the photos from the camera to the Mac, enhance/edit and share (Facebook, flickr) or print or make photo books. This flow (with some face recognition, red-eye removal, event/album creation etc.) works like a charm &#8212; if you are just starting out with your new digital camera. What if you already have 20,000 old photos and scans on your old computer (in &#8220;My Pictures&#8221;)?</p>
<p>This is the problem I was faced with when I started playing with iPhoto. I pride myself in anticipating such problems. So, I decided to import my old library very carefully. While importing &#8220;My Pictures&#8221; (which was fairly organized to begin with), I went through it folder by folder, dragging-and-dropping them on iPhoto and, at the same time, labeling them (and the photos therein) with what I thought were appropriate colors. (I used the &#8220;Get Info&#8221; function in Finder for color labels.) I thought I was being clever, but I ended up with a fine (but colorful) mess, with my folders and photos sporting random colors. It looked impossible to compare and figure out and where my 20,000 photos got imported to in iPhoto; so I decided to write my very first Mac App &#8212; <a href="http://buy.ads-ez.com/iPhotoTagger" target="_blank">iPhotoTagger</a>. It took me about a week to write it, but it sorted out my photo worries. Now I want to sell it and make some money.</p>
<p>Here is what it does. It first goes through your iPhoto library and catalogs what you have there. It then scans the folder you specify and compares the photos in there with those in your library. If a photo is found exactly once, it will get a Green label, so that it stands out when you browse to it in your Finder (which is Mac-talk for Windows Explorer). Similarly, if the photo appears more than once in your iPhoto library, it will be tagged in Yellow. And, going the extra-mile, iPhotoTagger will color your folder Green if all the photos within have been imported into your iPhoto library. Those folders that have been partially imported will be tagged Yellow.</p>
<p>The photo comparison is done using Exif data, and is fairly accurate. Note that iPhotoTagger doesn&#8217;t modify anything within your iPhoto library. Doing so would be unwise. It merely reads the library to gather information.</p>
<p>This first version (V1.0) is released to test the waters, as it were, and is priced at $1.99. If there is enough interest, I will work on V2.0 with improved performance (using Perl and SQLite, if you must know). I will price it at $2.99. And, if the interest doesn&#8217;t wane, a V3.0 (for $3.99) will appear with a proper help file, performance pane, options to choose your own color scheme, SpotLight comments (and, if you must know, probably rewritten in Objective-C). Before you rush to send me money, please know that iPhotoTagger requires Snow Leopard and Lion (OS-X 10.6 and 10.7). If in doubt, you can <a href="http://buy.ads-ez.com/iPhotoTagger/iPhotoTagger.zip" target="_blank">download the lite version</a> and play with it. It is fully functional, and will create lists of photos/folders to be tagged in Green and Yellow, but won&#8217;t actually tag them.</p>

			<content:encoded><![CDATA[<p>Here is a French joke that is funny only in French. I present it here as a puzzle to my English-speaking readers.</p>
<p>This colonel in the French army was in the restroom. As he was midway through the business of relieving his bladder, he becomes aware of this tall general standing next to him, and realizes that it is none other than Charles De Gaulle. Now, what do you do when you find yourself a sort of captive audience next to your big boss for a couple of minutes? Well, you have to make smalltalk. So this colonel rakes his brain for a suitable subject. Noticing that the restroom is a classy tip-top joint, he ventures:</p>
<p>&#8220;Belle piece!&#8221; (&#8220;Nice room!&#8221;)</p>
<p>CDG&#8217;s ice-cold tone indicates to him the enormity of the professional error he has just committed:</p>
<p>&#8220;Regardez devant vous.&#8221; (&#8220;Don&#8217;t peek!&#8221;)</p>

		<description><![CDATA[<p>Wondering if our so-called progress is actually a blind march toward chaos an anarchy, I present a slightly disorganized line of thought in this short piece.</p> <a href="http://www.thulasidas.com/2011-09/luddite-thoughts.htm">Continue reading <span class="meta-nav">&#8594;</span></a>]]></description>
			<content:encoded><![CDATA[<p>For all its pretentiousness, French cuisine is pretty amazing. Sure, I&#8217;m no degustation connoisseur, but the French really know how to eat well. It is little wonder that the finest restaurants in the world are mostly French. The most pivotal aspect of a French dish usually is its delicate sauce, along with choice cuts, and, of course, inspired presentation (AKA huge plates and minuscule servings). The chefs, those artists in their tall white hats, show off their talent primarily in the subtleties of the sauce, for which knowledgeable patrons happily hand over large sums of money in those establishments, half of which are called &#8220;Cafe de Paris&#8221; or have the word &#8220;petit&#8221; in their names.</p>
<p>Seriously, sauce is king (to use Bollywood lingo) in French cuisine, so I found it shocking when I saw this on BBC that more and more French chefs were resorting to factory-manufactured sauces. Even the slices of boiled eggs garnishing their overpriced salads come in a cylindrical form wrapped in plastic. How could this be? How could they use mass-produced garbage and pretend to be serving up the finest gastronomical experiences?</p>
<p>Sure, we can see corporate and personal greed driving the policies to cut corners and use the cheapest of ingredients. But there is a small technology success story here. A few years ago, I read in the newspaper that they found fake chicken eggs in some Chinese supermarkets. They were &#8220;fresh&#8221; eggs, with shells, yolks, whites and everything. You could even make omelets with them. Imagine that &#8212; a real chicken egg probably costs only a few cents to produce. But someone could set up a manufacturing process that could churn out fake eggs cheaper than that. You have to admire the ingenuity involved &#8212; unless, of course, you have to eat those eggs.</p>
<p>The trouble with our times is that this unpalatable ingenuity is all pervasive. It is the norm, not the exception. We see it in tainted paints on toys, harmful garbage processed into fast food (or even fine-dining, apparently), poison in baby food, imaginative fine-print on financial papers and &#8220;EULAs&#8221;, substandard components and shoddy workmanship in critical machinery &#8212; on every facet of our modern life. Given such a backdrop, how do we know that the &#8220;organic&#8221; produce, though we pay four times as much for it, is any different from the normal produce? To put it all down to the faceless corporate greed, as most of us tend to do, is a bit simplistic. Going one step further to see our own collective greed in the corporate behavior (as I proudly did a couple of times) is also perhaps trivial. What are corporates these days, if not collections of people like you and me?</p>
<p>There is something deeper and more troubling in all this. I have some disjointed thoughts, and will try to write it up in an ongoing series. I suspect these thoughts of mine are going to sound similar to the luddite ones un-popularized by the infamous Unabomber. His idea was that our normal animalistic instincts of the hunter-gatherer kind are being stifled by the modern societies we have developed into. And, in his view, this unwelcome transformation and the consequent tension and stress can be countered only by an anarchical destruction of the propagators of our so-called development &#8212; namely, universities and other technology generators. Hence the bombing of innocent professors and such.</p>
<p>Clearly, I don&#8217;t agree with this luddite ideology, for if I did, I would have to first bomb myself! I&#8217;m nursing a far less destructive line of thought. Our technological advances and their unintended backlashes, with ever-increasing frequency and amplitude, remind me of something that fascinated my geeky mind &#8212; the phase transition between structured (laminar) and chaotic (turbulent) states in physical systems (when flow rates cross a certain threshold, for instance). Are we approaching such a threshold of phase transition in our social systems and societal structures? In my moody luddite moments, I feel certain that we are.</p>

This article was published in a magazine in Singapore. <a href="http://www.thulasidas.com/2010-09/the-unreal-universe.htm">Continue reading <span class="meta-nav">&#8594;</span></a>]]></description>
			<content:encoded><![CDATA[<p>We know that our universe is a bit unreal. The stars we see in the night sky, for instance, are not really there. They may have moved or even died by the time we get to see them. This delay is due to the time it takes for light from the distant stars and galaxies to reach us. We know of this delay. The sun that we see now is already eight minutes old by the time we see it. This delay is not a big deal; if we want to know what is going on at the sun right now, all we have to do is to wait for eight minutes. We do have to &#8220;correct&#8221; for the delay in our perception due to the finite speed of light before we can trust what we see.</p>
<p>Now, this effect raises an interesting question &#8212; what is the &#8220;real&#8221; thing that we see? If seeing is believing, the stuff that we see should be the real thing. Then again, we know of the light travel time effect. So we should correct what we see before believing it. What then does &#8220;seeing&#8221; mean? When we say we see something, what do we really mean?</p>
<p><script type="text/javascript"><!--
 amazon('B003YRILE8', '[The Unreal Universe]', 'The Unreal Universe -- Kindle Edition for $9.95') ;
//--></script>Seeing involves light, obviously. It is the finite (albeit very high) speed of light influences and distorts the way we see things. This fact should hardly come as a surprise because we do know that there is a delay in seeing objects like stars. What is surprising (and seldom highlighted) is that when it comes to seeing moving objects, we cannot back-calculate the same way we take out the delay in seeing the sun. If we see a celestial body moving at an improbably high speed, we cannot figure out how fast and in what direction it is &#8220;really&#8221; moving without making further assumptions. One way of handling this difficulty is to ascribe the distortions in our perception to the fundamental properties of the arena of physics &#8212; space and time. Another course of action is to accept the disconnection between our perception and the underlying &#8220;reality&#8221; and deal with it in some way.</p>
<p>This disconnect between what we see and what is out there is not unknown to many philosophical schools of thought. Phenomenalism, for instance, holds the view that space and time are not objective realities. They are merely the medium of our perception. All the phenomena that happen in space and time are merely bundles of our perception. In other words, space and time are cognitive constructs arising from perception. Thus, all the physical properties that we ascribe to space and time can only apply to the phenomenal reality (the reality as we sense it). The noumenal reality (which holds the physical causes of our perception), by contrast, remains beyond our cognitive reach.</p>
<p>One, almost accidental, difficulty in redefining the effects of the finite speed of light as the properties of space and time is that any effect that we do understand gets instantly relegated to the realm of optical illusions. For instance, the eight-minute delay in seeing the sun, because we can readily understand it and disassociate it from our perception using simple arithmetic, is considered a mere optical illusion. However, the distortions in our perception of fast moving objects, although originating from the same source are considered a property of space and time because they are more complex. At some point, we have to come to terms with the fact that when it comes to seeing the universe, there is no such thing as an optical illusion, which is probably what Goethe pointed out when he said, &#8220;Optical illusion is optical truth.&#8221;</p>
<p><script type="text/javascript"><!--
 amazon('9810575947', '[The Unreal Universe]', 'The Unreal Universe -- Paperback from Amazon for $15.95') ;
//--></script>The distinction (or lack thereof) between optical illusion and truth is one of the oldest debates in philosophy. After all, it is about the distinction between knowledge and reality. Knowledge is considered our view about something that, in reality, is &#8220;actually the case.&#8221; In other words, knowledge is a reflection, or a mental image of something external. In this picture, the external reality goes through a process of becoming our knowledge, which includes perception, cognitive activities, and the exercise of pure reason. This is the picture that physics has come to accept. While acknowledging that our perception may be imperfect, physics assumes that we can get closer and closer to the external reality through increasingly finer experimentation, and, more importantly, through better theorization. The Special and General Theories of Relativity are examples of brilliant applications of this view of reality where simple physical principles are relentlessly pursued using the formidable machine of pure reason to their logically inevitable conclusions.</p>
<p>But there is another, competing view of knowledge and reality that has been around for a long time. This is the view that regards perceived reality as an internal cognitive representation of our sensory inputs. In this view, knowledge and perceived reality are both internal cognitive constructs, although we have come to think of them as separate. What is external is not the reality as we perceive it, but an unknowable entity giving rise to the physical causes behind sensory inputs. In this school of thought, we build our reality in two, often overlapping, steps. The first step consists of the process of sensing, and the second one is that of cognitive and logical reasoning. We can apply this view of reality and knowledge to science, but in order do so, we have to guess the nature of the absolute reality, unknowable as it is.</p>
<p>The ramifications of these two different philosophical stances described above are tremendous. Since modern physics has embraced a non-phenomenalistic view of space and time, it finds itself at odds with that branch of philosophy. This chasm between philosophy and physics has grown to such a degree that the Nobel prize winning physicist, Steven Weinberg, wondered (in his book &#8220;Dreams of a Final Theory&#8221;) why the contribution from philosophy to physics have been so surprisingly small. It also prompts philosophers to make statements like, &#8220;Whether &#8216;noumenal reality causes phenomenal reality&#8217; or whether &#8216;noumenal reality is independent of our sensing it&#8217; or whether &#8216;we sense noumenal reality,&#8217; the problem remains that the concept of noumenal reality is a totally redundant concept for the analysis of science.&#8221;</p>
<p>From the perspective of cognitive neuroscience, everything we see, sense, feel and think is the result of the neuronal interconnections in our brain and the tiny electrical signals in them. This view must be right. What else is there? All our thoughts and worries, knowledge and beliefs, ego and reality, life and death &#8212; everything is merely neuronal firings in the one and half kilograms of gooey, grey material that we call our brain. There is nothing else. Nothing!</p>
<p>In fact, this view of reality in neuroscience is an exact echo of phenomenalism, which considers everything a bundle of perception or mental constructs. Space and time are also cognitive constructs in our brain, like everything else. They are mental pictures our brains concoct out of the sensory inputs that our senses receive. Generated from our sensory perception and fabricated by our cognitive process, the space-time continuum is the arena of physics. Of all our senses, sight is by far the dominant one. The sensory input to sight is light. In a space created by the brain out of the light falling on our retinas (or on the photo sensors of the Hubble telescope), is it a surprise that nothing can travel faster than light?</p>
<p>This philosophical stance is the basis of my book, <em><a href="http://www.amazon.com/exec/obidos/ASIN/9810575947/unrblo-20">The Unreal Universe</a></em>, which explores the common threads binding physics and philosophy. Such philosophical musings usually get a bad rap from us physicists. To physicists, philosophy is an entirely different field, another silo of knowledge, which holds no relevance to their endeavors. We need to change this belief and appreciate the overlap among different knowledge silos. It is in this overlap that we can expect to find great breakthroughs in human thought.</p>
<p>The twist to this story of light and reality is that we seem to have known all this for a long time. Classical philosophical schools seem to have thought along lines very similar to Einstein&#8217;s reasonings. The role of light in creating our reality or universe is at the heart of Western religious thinking. A universe devoid of light is not simply a world where you have switched off the lights. It is indeed a universe devoid of itself, a universe that doesn&#8217;t exist. It is in this context that we have to understand the wisdom behind the statement that &#8220;the earth was without form, and void&#8221; until God caused light to be, by saying &#8220;Let there be light.&#8221;</p>
<p>The Quran also says, &#8220;Allah is the light of the heavens and the earth,&#8221; which is mirrored in one of the ancient Hindu writings: &#8220;Lead me from darkness to light, lead me from the unreal to the real.&#8221; The role of light in taking us from the unreal void (the nothingness) to a reality was indeed understood for a long, long time. Is it possible that the ancient saints and prophets knew things that we are only now beginning to uncover with all our supposed advances in knowledge?</p>
<p>I know I may be rushing in where angels fear to tread, for reinterpreting the scriptures is a dangerous game. Such alien interpretations are seldom welcome in the theological circles. But I seek refuge in the fact that I am looking for concurrence in the metaphysical views of spiritual philosophies, without diminishing their mystical and theological value.</p>
<p>The parallels between the noumenal-phenomenal distinction in phenomenalism and the <em>Brahman-Maya</em> distinction in <em>Advaita </em>are hard to ignore. This time-tested wisdom on the nature of reality from the repertoire of spirituality is now being reinvented in modern neuroscience, which treats reality as a cognitive representation created by the brain. The brain uses the sensory inputs, memory, consciousness, and even language as ingredients in concocting our sense of reality. This view of reality, however, is something physics is yet to come to terms with. But to the extent that its arena (space and time) is a part of reality, physics is not immune to philosophy.</p>
<p>As we push the boundaries of our knowledge further and further, we are beginning to discover hitherto unsuspected and often surprising interconnections between different branches of human efforts. In the final analysis, how can the diverse domains of our knowledge be independent of each other when all our knowledge resides in our brain? Knowledge is a cognitive representation of our experiences. But then, so is reality; it is a cognitive representation of our sensory inputs. It is a fallacy to think that knowledge is our internal representation of an external reality, and therefore distinct from it. Knowledge and reality are both internal cognitive constructs, although we have come to think of them as separate.</p>
<p>Recognizing and making use of the interconnections among the different domains of human endeavor may be the catalyst for the next breakthrough in our collective wisdom that we have been waiting for.</p>

Sophistication is a French invention. The French are masters when it comes to nurturing, and more importantly, selling sophistication. Think of some expensive (and therefore classy) brands.

			<content:encoded><![CDATA[<p>Sophistication is a French invention. The French are masters when it comes to nurturing, and more importantly, selling sophistication. Think of some expensive (and therefore classy) brands. Chances are that more than half of the ones that spring to mind would be French. And the other half would be distinctly French sounding wannabes. This world domination in sophistication is impressive for a small country of the size and population of Thailand.</p>
<p>How do you take a handbag manufactured in Indonesia, slap on a name that only a handful of its buyers can pronounce, and sell it for a profit margin of 1000%? You do it by championing sophistication; by being an icon that others can only aspire to be, but never ever attain. You know, kind of like perfection. No wonder Descartes said something that sounded suspiciously like, &#8220;I think in French, therefore I am!&#8221; (Or was it, &#8220;I think, therefore I am French&#8221;?)</p>
<p>I am amazed by the way the French manage to have the rest of the world eat things that smell and taste like feet. And I stand in awe of the French when the world eagerly parts with their hard earned dough to gobble up such monstrosities as fattened duck liver, fermented dairy produce, pig intestines filled with blood, snails, veal entrails and whatnot.</p>
<p>The French manage this feat, not by explaining the benefits and selling points of these, ahem&#8230;, products, but by a perfecting a supremely sophisticated display of incredulity at anyone who doesn&#8217;t know their value. In other words, not by advertising the products, but by embarrassing you. Although the French are not known for their physical stature, they do an admirable job of looking down on you when needed.</p>
<p>I got a taste of this sophistication recently. I confessed to a friend of mine that I never could develop a taste for caviar &#8212; that quintessential icon of French sophistication. My friend looked askance at me and told me that I must have eaten it wrong. She then explained to me the right way of eating it. It must have been my fault; how could anybody not like fish eggs? And she would know; she is a classy SIA girl.</p>
<p>This incident reminded me of another time when I said to another friend (clearly not as classy as this SIA girl) that I didn&#8217;t quite care fore Pink Floyd. He gasped and told me never to say anything like that to anybody; one always loved Pink Floyd.</p>
<p>I should admit that I have had my flirtations with bouts of sophistication. My most satisfying moments of sophistication came when I managed to somehow work a French word or expression into my conversation or writing. In a recent column, I managed to slip in &#8220;tête-à-tête,&#8221; although the unsophisticated printer threw away the accents. Accents add a flourish to the level of sophistication because they confuse the heck out of the reader.</p>
<p>The sneaking suspicion that the French may have been pulling a fast one on us crept up on me when I read something that Scott Adams (of Dilbert fame) wrote. He wondered what this ISO 9000 fad was all about. Those who secure the ISO certification proudly flaunt it, while everybody else seems to covet it. But does anyone know what the heck it is? Adams conjectured that it was probably a practical joke a bunch of inebriated youngsters devised in a bar. &#8220;ISO&#8221; sounded very much like &#8220;Iz zat ma beer?&#8221; in some eastern European language, he says.</p>
<p>Could this sophistication fad also be a practical joke? A French conspiracy? If it is, hats off to the French!</p>
<p>Don&#8217;t get me wrong, I&#8217;m no Francophobe. Some of my best friends are French. It is not their fault if others want to imitate them, follow their gastronomical habits and attempt (usually in vain) to speak their tongue. I do it too &#8212; I swear in French whenever I miss an easy shot in badminton. After all, why waste an opportunity to sound sophisticated, n&#8217;est-ce pas?</p>

			<content:encoded><![CDATA[<p>Philosophy means love wisdom. But it enjoys none of the glamor that its definition would imply. For instance, in one of the board games that I played with the kids recently, the chance card that would make you bankrupt actually read, &#8220;Turn into a philosopher and lose all your money!&#8221; This card was particularly troubling for me because I do plan to take up philosophy seriously, hopefully soon.</p>
<p>The lack of correlation between wisdom and worldly rewards is unsettling, especially to those who are foolish enough to consider themselves wise. Why is it that the love of wisdom wouldn&#8217;t translate to glory, riches and creature comforts? The reason, as far as I can tell, is a deep disconnect between philosophy and life &#8212; as a wise (but distinctly unphilosophical) friend of mine put it in one of those hazy late-night stupors of the graduate years, &#8220;Philosophy to real life is what masturbation is to sex.&#8221; Yes, the masses see the love of wisdom as pointless intellectual masturbation. This view is perhaps echoed in what Russell said once:</p>
<p><script type="text/javascript"><!--
 Prolog('The point of philosophy is to start with something so simple as not to seem worth stating, and to end with something so paradoxical that no one will believe it.', 'Bertrand Russell', 'russell') ;
// --></script></p>
<p>Philosophy busies itself with things that seem obvious, to come up with something grandiose. This apparent obsession with trivialities is a false impression. Dispelling this impression is the purpose of this post. Let me start by pointing out one fact. Philosophy is at the root of everything that you do. You live a good, moral life? Or even a lousy, greedy one? Your behavior, choices and reasons are studied in Ethics. You are a <a href="http://www.thulasidas.com/category/topical/quant-finance">quant</a>, or do stuff technical or mathematical? Logic. Into physics and worship <a href="http://www.thulasidas.com/2009-02/change-the-facts.htm">Einstein</a>? You cannot then ignore the metaphysical aspects of <a href="http://www.thulasidas.com/2008-11/what-is-space.htm">space</a> and <a href="http://www.thulasidas.com/2009-10/only-a-matter-of-time.htm">time</a>. Lawyer? Yeah, Rhetorics. Knowledge worker? Epistemology defines what knowledge is. Artist? Fashion designer? Work in the movie industry? We got you covered in Aesthetics. You see, every avenue of human endeavor has a philosophic underpinning to it.</p>
<p>Pointing out this underpinning is, in reality, not as big a deal as I make it out to be. It is merely a matter of definition. I define philosophy to be whatever it is that &#8220;underpins&#8221; all aspects of life, and then point out this underpinning as evidence of its importance. The real value of philosophy is in structuring our thoughts and guiding them, for instance, in perceiving the speciousness and subtle circularity of my underpinning-therefore-important argument. Philosophy teaches us that nothing stands own its own, and that there are structures and schools of thought that illuminate questions that befuddle us. There are scaffolds to support us, and giants on whose shoulders we can stand to see far and clear. To be sure, some of these giants may be facing the wrong way, but it is again the boldness and independence that come with philosophy that will help us see the errors in their ways. Without it, learning becomes indoctrination, and in our quest to assimilate information into wisdom, we get stuck somewhere in between &#8212; perhaps at the level of knowledge.</p>
<p>All this discussion still doesn&#8217;t give us a clue as to the disquieting connection between philosophy and bankruptcy. For when a great man voices his existential anguish as, &#8220;I think, therefore I am,&#8221; we can always say (as we often do), &#8220;Good for you mate, whatever works for you!&#8221; and go about our life.</p>
<p>Love of wisdom perhaps facilitates its acquisition, and the purpose of wisdom is only wisdom. It is very much like life, the purpose of which is merely to live a little longer. But without philosophy, how do we see the meaning of life? Or lack thereof?</p>

			<content:encoded><![CDATA[<p>This post started as a reply to <a href="http://www.thulasidas.com/2009-08/the-god-delusion.htm/comment-page-1#comment-501">M Cuffe&#8217;s comment</a> on my post on <a href="http://www.thulasidas.com/2009-08/the-god-delusion.htm"><em>The God Delusion</em></a>. M Cuffe suggested that I&#8217;m merely asserting an individual&#8217;s right to be irrational, or ignorant. Yes, I am indeed saying that one has the right to be irrational. But that statement stems from something that I believe is deeper. It stems from what we mean by rationality, and why we think it is a good thing to be rational. I know it sounds &#8220;irrational,&#8221; but I&#8217;m talking about rationality as Persig talked about it in <a href="http://www.thulasidas.com/2008-08/zen-and-the-art-of-motorcycle-maintenance.htm"><em>Zen and the Art of Motorcycle Maintenance</em></a>. </p>
<p>Stepping back a bit, rationality is quintessentially a worldview. By rational, we mean things that seem normal to our commonsense. So the notion of a nuclear bomb moving or obliterating a mountain is rational, although we have never seen it. You believe it because it is consistent with your worldview. I believe it too, trust me. I was a nuclear physicist not too long ago. <img src='http://www.thulasidas.com/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' /> </p>
<p>And a god (or faith) moving mountains is clearly ludicrous to our rationality. I&#8217;m not asking people to give equal rational weight to faith and bomb moving mountains. I&#8217;m merely encouraging them to examine why they believe in one and not the other. Calling one more rational is just another way of saying that you choose to believe one more than the other. Why?</p>
<p>Thinking along those lines, I come to the conclusion that it is only a question of worldviews or belief systems. I personally subscribe to your worldview based on rationality as well, which is why I consider myself also an atheist (although one of my readers thought I was merely confused <img src='http://www.thulasidas.com/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' /> ) </p>
<p>A god as an old man hiding behind the clouds is not consistent with our worldview. But it may have been a metaphor for something else. Let me explain. We have these abstract concepts of happiness, perfection, grief etc. Are these things real? Should we believe they exist? Such questions don&#8217;t make too much sense because these concepts are all in our minds. But then, what isn&#8217;t? </p>
<p>Let&#8217;s take perfection, for instance. Let&#8217;s say we assign some human form to it, so that we could explain it to a child or something. We then call it, say, the goddess of perfection or whatever. Over generations, for whatever reason, the notion of perfection disappears from our awareness, but the metaphor of the goddess remains. Now, to somebody who believes in the reality perfection, and therefore the existence of the goddess, it is not a delusion. In that belief system, in that context and worldview, it makes perfect sense. But in the absence of the abstract concept of perfection, the goddess becomes a delusion.</p>
<p>I believe that a large part of our collective wisdom is handed down in the form of such metaphors. Instead of dismissing them as delusions because their context is gone, we should perhaps try harder to rediscover the lost concepts. I also believe such metaphors exist in other fields that seem to work well. Take, for instance, the Qi concept in traditional Chinese medicine, the five elements (or three body types) in Ayurveda and so on. To the extent that traditional Chinese medicine and Ayurveda work, there has to be some knowledge buried in those practices. If we write off their basis merely because their metaphors are not consistent with our rationality, we may be writing off some potential sources of new or forgotten knowledge.</p>
<p>In addition, I believe that some of our smarter geniuses indeed see delusional metaphors in what we take to be <a href="http://www.thulasidas.com/2008-11/what-is-space.htm">supremely real</a>.<br />

			<content:encoded><![CDATA[<p><em>[This post is a review of my forthcoming book, "<a href="http://pqd.thulasidas.com" target="new"><strong>Principles of Quantitative Development</strong></a>," to be published by John Wiley &amp; Sons in Feb 2010. This review is written by <strong>Shayne Fletcher</strong>, Executive Director, Nomura, and author of  "</em><em>Financial Modelling in Python</em>," and is posted here with the reviewer's permission.]</p>
<p>In &#8220;Principles of Quantitative Development&#8221;, Thulasidas has offered a contribution that is somewhat unique in the literature associated with the field of Quantitative Development. In that specialised, narrow domain, technical books abound. Most such titles are concerned with the intricacies of the application of specific programming language to the problems of financial engineering or, expositions of advanced mathematics as used in the pricing models of exotic financial derivative products. Thulasidas however has taken a very different tact. Focusing instead on what he terms &#8220;the big picture&#8221;, Thulasidas offers us his insights into the role of Quantitative Development in the broader context of a bank&#8217;s &#8220;trading platform&#8221;. Armed with such insights, he shows us how an understanding of the varied usages of the trading platform can and should be used to influence and shape its design.</p>
<p>In the opening chapters, the book is concerned with defining what is meant by the term &#8220;trading platform&#8221;. In doing so, Thulasidas necessarily reviews the &#8220;architecture&#8221; of a bank from the point of view of a Quantitative Developer. That is, he discusses the nature and interactions of the front, middle and back offices of a bank, the different roles that professionals in each of those areas satisfy and how each of their respective needs induce a different set of requirements on the trading platform. Moving on, he reviews the nature of trades, the so-called trade &#8220;life cycle&#8221; and how different views of a trade are required as a function of the life cycle and the business role of the user.</p>
<p>Having established a broad understanding of the requirements for a trading platform, Thulasidas turns his attention to translating those requirements into design decisions for trading platforms. Along the way he considers such aspects of design as choice of programming languages, issues relating to scalability and extensibility, security and auditing, representations for market and trade data and a trading platform&#8217;s macro architecture whilst all the way remaining focussed on ensuring that all business needs identified in the earlier chapters are given consideration and catered for.</p>
<p>Going from the general to the specific, Thulasidas in later chapters introduces a flexible derivatives pricing tool (the source code for which accompanies the book). This program in itself will no doubt serve as an excellent starting point for Quantitative Development teams charged with the production of an in-house trading platform. Perhaps of even greater benefit though is Thulasidas&#8217;s critique of the pricing tool, that is, in his explanation of how the supplied program fails to meet the requirements of a complete trading platform and how the program needs to be extended in order to be considered one. In this way, the line of thought of earlier chapters is reinforced and brought sharply into focus.</p>
<p>Throughout the book, Thulasidas manages to convey his ideas with remarkable eloquence and lucidity. Understanding is enhanced by numerous rich graphics outlining processes and their design (both in the software and work-flow sense). The reader&#8217;s attention and interest is never lost and a great deal of entertainment is to be found in the numerous side-bars, the &#8220;Big Pictures&#8221; (in effect an enjoyable mini-series of magazine style articles in their own right).</p>
<p>As Thulasidas himself notes, the subject matter of his book is broad. Accordingly, the potential readership of this title is equally broad. Notably, Quantitative Developers at the beginning of their careers stand most to gain from this book. The fact is though that even the most seasoned of banking professionals would profit from its reading. Quantitative Developers, Quantitative Analysts, Traders, Risk Managers, IT professionals and their Project Managers, individuals considering switching from academia or other industries to a career in banking&#8230; Readers from each and all of these groups will find Thulasidas&#8217;s work informative and thought provoking.</p>

			<content:encoded><![CDATA[<p>In my post on <a href="/2009-08/a-plausible-god.htm">A Plausible God</a>, I cited blind-sight as an example of sensing that does not lead to conscious perception. This remarkable neurological syndrome illustrates the tight interconnection between our sense of reality and consciousness. Larry Weiscrantz and Alan Cowey discovered blind-sight at Oxford about 25 years ago.</p>
<p>Blindness can be physiological, when the physical eye is not functioning properly. Or it can be neurological, when the eye is fne but the visual signal processing is impaired. For example, if our right visual cortex is damaged, we are blind on the left side. When examining a patient with such a neurological blindness on one side, Weiscrantz shined a little spot of light on the patient’s blind side. Weiscrantz then asked the patient to point to it. The patient protested that he could not see it and could not possibly point to it. Weiscrantz asked him to try anyway. The patient then proceeded to point accurately to the spot of light that he could not consciously perceive.</p>
<p>After hundreds of trials, it became obvious that the patient could point correctly in ninety-nine percent of trials, even though he claimed on each trial that he was only guessing. How did the patient determine the location of an invisible object and point to it accurately? The neurological reason is that we all have two visual pathways. The new visual pathway goes through the visual cortex. The old, backup pathway runs through our brain stem to the superior colliculus.</p>
<p>The cause of our patient’s blindness was that his visual cortex was damaged, and it did not get the signals from one eye and  its optic nerves. But the signals took the parallel route to the superior colliculus, using the old pathway. This rerouting allowed him to locate the object in space and guide his hand accurately to point to the invisible object. What this syndrome of blind-sight shows us is that only the new visual pathway leads to a conscious experience. While the old pathway is perfectly usable (for survival, for instance), it does not lead to a conscious experience of vision.</p>
<p>An interesting neurological condition, no doubt. But blind-sight is more than that. It is a rather confounding philosophical conundrum. The spot of light that the patient could see &#8212; was it real? Sure, we know it was real. But what if all of us were blind-sighted? If some of us started developing a semblance of awareness as a result of our blind-sight, would we believe them, or call them delusional? If there are senses that we can be unaware of, how sure can we be of the &#8220;sensed&#8221;? Or of our &#8220;delusions&#8221;?</p>

			<content:encoded><![CDATA[<p>In my <a href="/2009-08/the-god-delusion.htm">review of <em>The God Delusion</em></a>, I promised to post a plausible concept of God. By &#8220;a plausible concept,&#8221; I mean a concept that doesn&#8217;t violate the known principles of science, and should therefore be consistent with the so-called scientific worldview. Mind you, the plausibility of the concept says nothing about its veracity; but it may say something about it being a delusion.</p>
<p>Of all the sciences, physics seems to be the one most at odds with the God concept. Clearly, evolutionary biology is none too happy with it either, if Dawkins is anything to go by. But that analysis is for another post.</p>
<p>Let&#8217;s start by analyzing a physicist&#8217;s way of &#8220;proving&#8221; that there is no God. The argument usually goes something like this:</p>
<blockquote><p>
If there is a God who is capable of affecting me in any way, then there should be some force exerted by that God on me. There should be some interaction. Since the interaction is big enough to affect me, I should be able to use this particular interaction to &#8220;measure&#8221; the God-intensity. So far, I haven&#8217;t been able to measure any such God-related force. So either there is no God that affects me in any way, or there is a God that affects me through deviously disguised interactions so that whenever I try to measure the interaction, I&#8217;m always fooled. Now, you tell me what is more likely. By Occam&#8217;s Razor, the simplest explanation (that there is no God that can affect me) has the highest chance of being right.
</p></blockquote>
<p>While this is a good argument (and one I used to make), it is built on a couple of implicit assumptions that are rather tricky to spot. The first assumption is that we cannot be affected by an interaction that we cannot sense. This assumption is not necessarily true. </p>
<p>Modern cosmology needs at least one other kind of interaction to account for dark matter and dark energy. Let&#8217;s call this unknown interaction the dark interaction. Even though we cannot sense the dark interaction, we are subject to it exactly as all other (known) matter is.  The existence of this interaction beyond our senses is sufficient to break the physicist&#8217;s proof. A plausible God can affect us, without our being able to sense it, through dark interactions.</p>
<p>But that is not the end of the story. The physicist can still argue, &#8220;Fine, if we cannot sense this God, how would we know he exists?  And why do so many people claim they can feel him?&#8221;  This argument is based on the assumptions on conscious experience and sensing. The hidden assumptions in the physicist&#8217;s questions (again, not necessarily true) are:</p>
<ol>
<li> Sensing should lead to a conscious perception.</li>
<li> All humans should have the same sense modality.</li>
</ol>
<p>An example of sensing that does not lead to conscious perception is the syndrome of blind sight. (I will post more on it later). A patient suffering from blind sight can point to the light spot he cannot consciously see. Thus, sensing without conscious perception is possible. The second assumption that all men are created equal (in terms of sensory modality) does not have any a priori reason to be true. It is possible that some people may be able to sense the dark interaction (or some other kind of interaction that God chooses) without being conscious of it.</p>
<p>So it is possible to argue that there is a God that affects us through a hitherto unknown interaction. And that some 95% of us can sense this interaction, and the others are atheists. What this argument illustrates is the plausibility of God. More precisely, it demonstrates the consistency of a concept of God with physics. It is not meant to be a proof of the existence of God. And that is why, despite the plausibility of God, I am still an atheist.</p>
<p>In retrospect, this argument did not have to be so complicated. It boils down to saying that there are limits on our knowledge, and to what is knowable. There is plenty of room for God outside these limits. It is also a classic argument by those who believe in God — you don&#8217;t know everything, so how do you know there <em>isn&#8217;t</em> a God?</p>

			<content:encoded><![CDATA[<p>I am an atheist. So I agree completely with all the arguments of <em>The God Delusion</em>. As a review of the book, that statement should be the end of it. But somehow the book gave me a strange feeling of dissatisfaction. You see, you may believe in God. Or you may not believe that there is a God. Or you may actively believe that there is no God. I fall in this the last category. But I still know that it is only my belief, and that thought fills me with a humility that I feel Dawkins lacks.</p>
<p>Now, it is one thing to say that the concept of God is inconsistent with the worldview you have developed, perhaps with the help of science. The concept is indeed very inconsistent with my personal worldview, which is why I am an atheist. But it is quite a different matter to discount the concept as a delusion. I believe that our knowledge is incomplete. And that there is plenty of room for a possible God to hide beyond the realms of our current knowledge. Does it mean that we should call our ignorance God and kneel before it? I don&#8217;t think so, but if you do, that is your prerogative.</p>
<p><script type="text/javascript"><!--
 amazon('0618680004') ;
// --></script>You see, it is all a question of what your worldview is. And how much rigor and consistency you demand of it. So, what is a worldview? In my opinion, a worldview is the extension of your knowledge. We all have a certain amount of knowledge. We also have a lot of sensory data that comes in every moment that we have to make sense of. We do most of this processing automatically, without conscious effort. But some of the higher level data and information that we encounter merit a closer analysis. How do we do it, given that we may not know much about it? We use our commonsense, our pre-conceived notions, the value systems our parents and teachers left in us and so on. One of these things that we use, or perhaps the totality of these things, is our worldview.</p>
<p>Let&#8217;s take an example. Douglas Adams tells us that dolphins are actually smarter than us and have regular inter-galactic communication. Well, we have no way of refuting this claim (which, of course, is only a joke). But our worldview tells us that it is unlikely to be true. And we don&#8217;t believe it &#8212; as though we know it is not true.</p>
<p>Another example, one that Bertram Russell once cited. Scripture tells us that faith can move mountains. Some people believe it. Science tells us that a nuclear blast can, well, move mountains. Some people believe that too. Note that most people haven&#8217;t directly witnessed either. But even for those who believe in the faith-mountain connection, nuclear energy moving mountains is a far more plausible belief. It is just a lot more consistent with our current worldview.</p>
<p>Now, just because God is a delusion according to Dawkins&#8217;s worldview (or mine, for that matter), should you buy it? Not unless it is inconsistent with yours as well. Worldviews are hard to change. So are our stances vis-a-vis God and science, when seen as belief-systems &#8212; as the movie Contact vividly illustrates. If you missed it, you should watch it. Repeatedly, if needed. It is a good movie anyway.</p>
<p><script type="text/javascript"><!--
 amazon('B001AQT0RC') ;
// --></script>It is true what they say about a scientific worldview being inconsistent with any sensible notion of a god. But worldviews are a funny thing. Nothing prevents you from tolerating inconsistencies in your worldview. Although Dawkins goes to some length to absolve Einstein of this lack of consistency, the conventional wisdom is that he did believe in God. The truth of the matter is that our collective knowledge (even after adding Einstein&#8217;s massive contribution) is limited. There really is plenty of room beyond its limits for God (or eight million gods, if I were to believe my parents), as I will try to show in my next post.</p>
<p>That, however, is only the tip of the iceberg. Once we admit that there are limits to our knowledge, and to what is knowable, we will soon find ourselves staring at other delusions. What is the point it discounting a God delusion, while embracing <a href="/2008-11/what-is-space.htm">a space-delusion</a>? In a universe that is unreal, everything is a delusion, not just God. I know, you think it is just <a href="/2008-08/zen-and-the-art-of-motorcycle-maintenance.htm">my sanity that is unreal</a>, but I may convince you otherwise. In another post.</p>

			<content:encoded><![CDATA[<p>The story of Helen Keller is the story of the dark reality that traps you in the absence of your senses. It is also an illustration of the role of language in breaking out of that darkness. Born a healthy child on June 27, 1880 in Alabama, Helen Keller was a perfectly happy baby &#8212; until the tender age of 19 months, when she was stricken with a strange illness that &#8220;they called acute congestion of the stomach and brain.&#8221; The terrible illness left her blind and deaf &#8212; &#8220;closed my eyes and ears and plunged me into the unconsciousness of a new-born baby,&#8221; as she would later write in her autobiography.</p>
<p>Disconnected from the physical world, Helen was trapped in her dark, silent reality (or the lack thereof). She did not even have thoughts or words in her mind, because the tragedy happened before she started talking. She could not learn from her parents like normal children, because she was blind and deaf. There were no special schools at that time for disadvantaged children like her. When she was seven, Helen&#8217;s parents contacted Alexander Graham Bell, the inventor of the telephone, who was also an educator of the deaf. Through his help, they found Anne Sullivan to tutor Helen. Anne Sullivan had special methods of making hand signs to spell out objects. Sadly, none of these tricks worked with Helen for a few frustrating months. She could not make the connection between the hand movements and the objects. It looked as though Helen would be doomed to her dark reality for ever. Here is how she made the connection and broke free from darkness. (This block quote is from Helen Keller&#8217;s autobiography &#8220;The Story of my Life,&#8221; which was ffirst published in 1903 and is in the public domain according to the US copyright laws.)</p>
<blockquote><p>
One day, while I was playing with my new doll, Miss Sullivan put my big rag doll into my lap also, spelled &#8220;d-o-l-l&#8221; and tried to make me understand that &#8220;d-o-l-l&#8221; applied to both. Earlier in the day we had had a tussle over the words &#8220;m-u-g&#8221; and &#8220;w-a-t-e-r.&#8221; Miss Sullivan had tried to impress it upon me that &#8220;m-u-g&#8221; is mug and that &#8220;w-a-t-e-r&#8221; is water, but I persisted in confounding the two. In despair she had dropped the subject for the time, only to renew it at the first opportunity. I became impatient at her repeated attempts and, seizing the new doll, I dashed it upon the floor. I was keenly delighted when I felt the fragments of the broken doll at my feet. Neither sorrow nor regret followed my passionate outburst. I had not loved the doll. In the still, dark world in which I lived there was no strong sentiment or tenderness. I felt my teacher sweep the fragments to one side of the hearth, and I had a sense of satisfaction that the cause of my discomfort was removed. She brought me my hat, and I knew I was going out into the warm sunshine. This thought, if a wordless sensation may be called a thought, made me hop and skip with pleasure.</p>
<p>We walked down the path to the well-house, attracted by the fragrance of the honeysuckle with which it was covered. Some one was drawing water and my teacher placed my hand under the spout. As the cool stream gushed over one hand she spelled into the other the word water, first slowly, then rapidly. I stood still, my whole attention fixed upon the motions of her fingers. Suddenly I felt a misty consciousness as of something forgotten &#8212; a thrill of returning thought; and somehow the mystery of language was revealed to me. I knew then that &#8220;w-a-t-e-r&#8221; meant the wonderful cool something that was flowing over my hand. That living word awakened my soul, gave it light, hope, joy, set it free! There were barriers still, it is true, but barriers that could in time be swept away.
</p></blockquote>
<p>The mystery of language is at the genesis of reality; it is what sweeps away the dark barriers standing between us and our conscious awareness of reality. It took Helen Keller out of nothingness into a world of reality, and if it is not the Word in &#8220;The Word was God,&#8221; I will never know what is.</p>

		<description><![CDATA[Of truth and beauty -- in physics and philosophy <a href="http://www.thulasidas.com/2009-02/change-the-facts.htm">Continue reading <span class="meta-nav">&#8594;</span></a>]]></description>
			<content:encoded><![CDATA[<p>There is beauty in truth, and truth in beauty. Where does this link between truth and beauty come from? Of course, beauty is subjective, and truth is objective &#8212; or so we are told. It may be that we have evolved in accordance with the beautiful Darwinian principles to see perfection in absolute truth.</p>
<p>The beauty and perfection I&#8217;m thinking about are of a different kind &#8212; those of ideas and concepts. At times, you may get an idea so perfect and beautiful that you know it has to be true. This conviction of truth arising from beauty may be what made Einstein declare:</p>
<p><script type="text/javascript"><!--
Prolog('If facts don\'t fit the theory, change the facts.', 'Albert Einstein', 'einstein') ;
// --></script></p>
<p>But this conviction about the veracity of a theory based on its perfection is hardly enough. Einstein&#8217;s genius really is in his philosophical tenacity, his willingness to push the idea beyond what is considered logical.</p>
<p>Let&#8217;s take an example. Let&#8217;s say you are in a cruising airplane. If you close the windows and somehow block out the engine noise, it will be impossible for you to tell whether you are moving or not. This inability, when translated to physics jargon, becomes a principle stating, &#8220;Physical laws are independent of the state of motion of the experimental system.&#8221;</p>
<p>The physical laws Einstein chose to look at were Maxwell&#8217;s equations of electromagnetism, which had the speed of light appearing in them. For them to be independent of (or covariant with, to be more precise) motion, Einstein postulated that the speed of light had to be a constant regardless of whether you were going toward it or away from it.</p>
<p>Now, I don&#8217;t know if you find that postulate particularly beautiful. But Einstein did, and decided to push it through all its illogical consequences. For it to be true, space has to contract and time had to dilate, and nothing could go faster than light. Einstein said, well, so be it. That is the philosophical conviction and tenacity that I wanted to talk about &#8212; the kind that gave us Special Relativity about a one hundred years ago.</p>
<p>Want to get to General Relativity from here? Simple, just find another beautiful truth. Here is one&#8230; If you have gone to Magic Mountain, you would know that you are weightless during a free fall (best tried on an empty stomach). Free fall is acceleration at 9.8 m/s/s (or 32 ft/s/s), and it nullifies gravity. So gravity is the same as acceleration &#8212; voila, another beautiful principle.</p>
<p><img src="/img/xt.png" alt="World line of airplanes" title="World lines of airplanes" class="alignleft" />In order to make use of this principle, Einstein perhaps thought of it in pictures. What does acceleration mean? It is how fast the speed of something is changing. And what is speed? Think of something moving in a straight line &#8212; our cruising airplane, for instance, and call the line of flight the X-axis. We can visualize its speed by thinking of a time T-axis at right angles with the X-axis so that at time = 0, the airplane is at x = 0. At time t, it is at a point x = v.t, if it is moving with a speed v. So a line in the X-T plane (called the world line) represents the motion of the airplane. A faster airplane would have a shallower world line. An accelerating airplane, therefore, will have a curved world line, running from the slow world line to the fast one.</p>
<p>So acceleration is curvature in space-time. And so is gravity, being nothing but acceleration. (I can see my physicist friends cringe a bit, but it is essentially true &#8212; just that you straighten the world-line calling it a geodesic and attribute <a href="http://www.thulasidas.com/2006-11/of-rotation-lt-and-acceleration.htm">the curvature to space-time</a> instead.)</p>
<p>The exact nature of the curvature and how to compute it, though beautiful in their own right, are mere details, as Einstein himself would have put it. After all, he wanted to know God&#8217;s thoughts, not the details.</p>

			<content:encoded><![CDATA[<p>I first found this modern-day classic in my father&#8217;s collection some thirty years ago, which meant that he bought it right around the time it was published. Looking back at it now, and after having read the book, as usual, many times over, I am surprised that he had actually read it. May be I am underestimating him in my colossal and unwarranted arrogance, but I just cannot see how he could have followed the book. Even after having lived in the USA for half a dozen years, and read more philosophy than is good for me, I cannot keep up with the cultural references and the pace of Charlie Citrine&#8217;s mind through its intellectual twists and turns. Did my father actually read it? I <a href="http://www.thulasidas.com/2008-10/death-of-a-parent.htm">wish I could ask him</a>.</p>
<p>Perhaps that is the point of this book, as it is with most classics &#8212; the irreversibility and finality of death. Or may be it is my jaundiced vision painting everything yellow. But Bellow does rage against this finality of death (just like most religions do); he comically postulates that it is our metaphysical denial that hides the immortal souls watching over us. Perhaps he is right; it certainly is comforting to believe it.</p>
<p>There is always an element of parternality in every mentor-prot&eacute;g&eacute; relationship. (Forgive me, I know it is a sexist view &#8212; why not maternality?) But I probably started this post with the memories of my father because of this perceived element in the Von Humboldt Fleischer &#8211; Charlie Citrine relationship, complete with the associated feelings of <a href="http://www.thulasidas.com/2008-08/choices-and-remorse.htm">guilt and remorse</a> on the choices that had to be made.</p>
<p><script type="text/javascript"><!--
 amazon('0140189440') ;
//--></script>As a book, <em>Humboldt&#8217;s Gift</em> is a veritable tour de force. It is a blinding blitz of erudition and wisdom, coming at you at a pace and intensity that is hard to stand up to. It talks about the painted veil, Maya, the many colored glasses staining the white radiance of eternity, and Hegel&#8217;s phenomenology as though they are like coffee and cheerios. To me, this dazzling display of intellectual fireworks is unsettling. I get a glimpse of the enormity of what is left to know, and the paucity of time left to learn it, and I worry. It is the ultimate <a href="http://www.thulasidas.com/2008-12/catch-22-by-joseph-heller.htm">Catch-22</a> &#8212; by the time you figure it all out, it is time to go, and the knowledge is useless. Perhaps knowledge has always been useless in that sense, but it is still a lot of fun to figure things out.</p>
<p>The book is a commentary on American materialism and the futility of idealism in our modern times. It is also about the small things where a heart finds fulfillment. Here is the setting of the story in a nutshell. Charlie Citrine, a prot&eacute;g&eacute; to Von Humboldt Fleischer, makes it big in his literary career. Fleischer himself, full of grandiose schemes for a cultural renaissance in America, dies a failure. Charlie&#8217;s success comes at its usual price. In an ugly divorce, his vulturous ex-wife, Denise, tries to milk him for every penny he&#8217;s worth. His mercenary mistress and a woman-and-a-half, Renata, targets his riches from other angles. Then there is the boisterous Cantabile who is ultimately harmless, and the affable and classy Thaxter who is much more damaging. The rest of the story follows some predictable, and some surprising twists. Storylines are something I stay away from in my reviews, for I don&#8217;t want to be posting spoilers.</p>
<p><script type="text/javascript"><!--
 amazon('0812979656') ;
//--></script>I am sure there is a name for this style of narration that jumps back and forth in time with no regard to chronology. I first noticed it in <a href="http://www.thulasidas.com/2008-12/catch-22-by-joseph-heller.htm">Catch-22</a> and recently in Arundhati Roy&#8217;s <em>God of Small Things</em>. It always fills me with a kind of awe because the writer has the whole story in mind, and is revealing aspects of it at will. It is like showing different projections of a complex object. This style is particularly suited for <em>Humboldt&#8217;s Gift</em>, because it is a complex object like a huge diamond, and the different projections show brilliant flashes of insights. Staining the white radiance of eternity, of course.</p>
<p>To say that <em>Humboldt&#8217;s Gift</em> is a masterpiece is like saying that sugar is sweet. It goes without saying. I will read this book many more times in the future because of its educational values (and because I love the reader in my audiobook edition). I would not necessarily recommend the book to others though. I think it takes a peculiar mind, one that finds sanity only in insane gibberish, and sees unreality in all the painted veils of reality, to appreciate this book.</p>
<p>In short, you have to be a bit cuckoo to like it. But, by the same convoluted logic, this negative recommendation is perhaps the strongest endorsement of all. So here goes&#8230; Don&#8217;t read it. I forbid it!</p>

		<description><![CDATA[This brief look at possibly the best book I have ever read is perhaps my last post in the book review series. At least for a short while, as I'm beginning to find it a bit hard to keep up with all the demands on my time now, what with my next book efforts and everything.

			<content:encoded><![CDATA[<p>May be it is only my tendency to see philosophy everywhere, but I honestly believe Maugham&#8217;s works are the classics they are because of their deep philosophical underpinnings. Their strong plots and Maugham&#8217;s masterful storytelling help, but what makes the timeless is the fact that Maugham gives voice to the restlessness of our hearts, and puts in words the stirring uncertainties of our souls. And our questions have always been the same. Where do we come from? What are we doing here? And where are we headed? Quo vadis?</p>
<p>Of all the books of this kind that I have read, and I have read many, <em>The Razor&#8217;s Edge</em> takes on the last question most directly. When Larry says, out of the blue, &#8220;The dead look so awfully dead.&#8221; we get an idea of what his quest, and indeed the inquiry of the book, is going to be.</p>
<p><script type="text/javascript"><!--
 amazon('1400034205') ;
//--></script>Larry Darrel is as close to human flawlessness that Maugham ever gets. His cynical disposition always produced vivid characters that were flawed human beings. We are used to snobbishness in Elliott Templeton, fear and hypocrisy in the vicar of Blackstable, self-loathing even in the self-image of Philip Carey, frivolity in Kitty Garstin, undue sternness in Walter Fane, the ludicrous buffoonery of Dirk Stroeve, abysmal cruelty in Charles Strickland, ultimate betrayal in Blanche Stroeve, fatal alcoholism in Sophie, incurable promiscuity in Mildred &#8212; an endless parade of gripping characters, everyone of them as far from human perfection as you and me.</p>
<p>But human perfection is what is sought and found in Larry Darrel. He is gentle, compassionate, handsome, single-mindedly hardworking, spiritually enlightened, simple and true. In one word, perfect. So it is only with an infinite amount of vanity that anybody can identify himself with Larry (as I secretly do). And it is a testament to Maugham&#8217;s mastery and skill that he could still make such an idealistic character human enough for some people to see themselves in him.</p>
<p>As I plod on with these review posts, I&#8217;m beginning to find them a bit useless. I feel that whatever needed to be said was already well said in the books to begin with. And, the books being classics, others have also said much about them. So why bother?</p>
<p>Let me wind up this post, and possibly this review series, with a couple of personal observations. I found it gratifying that Larry finally found enlightenment in my native land of Kerala. Written decades before the hippie exodus for spiritual fulfillment in India, this book is remarkably prescient. And, as a book on what life is all about, and how to live it to its spiritual fullness in our hectic age, <em>The Razor&#8217;s Edge</em> is a must read for everybody.</p>

			<content:encoded><![CDATA[<p>I&#8217;m embarrassed to admit it, but I didn&#8217;t &#8220;get&#8221; <em>Catch-22</em> the first time I read it. That was some twenty years ago, may be I was too young then. Halfway through my third read a few weeks ago, I suddenly realized &#8211; it was a caricature!</p>
<p>Caricatures are visual; or so I thought. <em>Catch-22</em>, however, is a literal caricature, the only one of its kind I have read. Looking for a story line in it that ridicules the blinding craziness of a cruelly crazy world is like looking for anguish in Guernica. It is everywhere and nowhere. Where shall I begin? I guess I will jot down the random impressions I got over my multiple reads.</p>
<p><em>Catch-22</em> includes one damning indictment on the laissez-faire, enterprise-loving, free market, capitalistic philosophy. It is in the form of the amiable, but ultimately heartless, Milo Minderbinder. With inconceivable pricing tactics, Milo&#8217;s enterprise makes money for his syndicate in which everybody has a share. What is good for the syndicate, therefore, has to be good for everybody, and we should be willing to suffer minor inconveniences like eating Egyptian cotton. During their purchasing trips, Yossarian and Dunbar have to put up with terrible working conditions, while Milo, mayor to countless towns and a deputy Shaw to Iran, enjoys all creature comforts and finer things in life. but, fret not, everybody has a share!</p>
<p><script type="text/javascript"><!--
 amazon('0684833395 ') ;
//--></script>It is hard to miss the parallels between Milo and the CEOs of modern corporations, begging for public bailouts while holding on to their private jets. But Heller&#8217;s uncanny insights assume really troubling proportions when Milo privatizes international politics and wars for everybody&#8217;s good. If you have read <em>The Confessions of an Economic Hitman</em>, you would be worried that the warped exaggerations of Heller are still well within the realm of reality. The icing on the cake comes when someone actually demands his share &#8212; Milo gives him a worthless piece of paper, with all pomp and ceremony! Remind you of your Lehman minibonds? Life indeed is stranger than fiction.</p>
<p><script type="text/javascript"><!--
 amazon('0452287081','','','alignright') ;
//--></script>But Milo&#8217;s exploits are but a minor side story in <em>Catch-22</em>. The major part of it is about crazy Yossarian&#8217;s insanity, which is about the only thing that makes sense in a world gone made with war and greed and delusions of futile glory.</p>
<p>Yossarian&#8217;s comical, yet poignant dilemmas put the incongruities of life in an unbearably sharp focus for us. Why is it crazy to try to stay alive? Where is the glory in dying for some cause when death is the end of everything, including the cause and the glory?</p>
<p>Along with Yossarian, Heller parades a veritable army of characters so lifelike that you immediately see them among your friends and family, and even in yourself. Take, for instance, the Chaplin&#8217;s metaphysical musings, Appleby&#8217;s flawless athleticism, Orr&#8217;s dexterity, Colonel Cathcart&#8217;s feathers and black-eyes, General Peckam&#8217;s prolix prose, Doc Daneeka&#8217;s selfishness, Aarfy&#8217;s refusal to hear, Nately&#8217;s whore, Luciana&#8217;s love, Nurse Duckett&#8217;s body, the 107 year old Italian&#8217;s obnoxious words of wisdom, Major Major&#8217;s shyness, Major &#8212; de Caverley&#8217;s armyness &#8212; each a masterpiece in itself!</p>
<p>On second thought, I feel that this book is too big a chef d&#8217;oervre for me to attempt to review. All I can do is to recommend that you read it &#8212; at least twice. And leave you with my take-away from this under-rated epic.</p>
<p>Life itself is the ultimate catch 22, inescapable and water-tight in every possible way imaginable. The only way to make sense of life is to understand death. And the only way to understand death is to stop living. Don&#8217;t you feel like letting out a respectful whistle like Yossarian at this simple beauty of this catch of life? I do!</p>

			<content:encoded><![CDATA[<h4>The Straits Times</h4>
<p><img class="alignleft" src="/img/pback-cover.gif" alt="pback-cover (17K)" />The national newspaper of Singapore, the Straits Times, lauds the readable and conversation style used in <em>The Unreal Universe</em> and recommends it to anybody who wants to learn about life, the universe and everything.<br />
<script type="text/javascript"><!--

<h4><a title="Wendy is the Senior Executive Editor for Religion, Philosophy and Animal Studies at Columbia University Press." href="javascript:popUpFat('http://cup.columbia.edu/static/Wendy-Lochner')">Wendy Lochner</a></h4>
<p>Calling <em>The Unreal Universe</em> a good read, Wendy says, &#8220;It&#8217;s well written, very clear to follow for the nonspecialist.&#8221;</p>
<h4><a title="Bobbie is the author of Write In Style, a   triple-award-winning textbook for writers of fiction and nonfiction. She is the Owner of Zebra Communications, Atlanta, GA (since 1992). She is editor, ghostwriter, book doctor, copywriter, consultant, seminar and workshop leader." href="javascript:popUpFat('http://www.zebraeditor.com/mentor.shtml')">Bobbie Christmas</a></h4>
<p>Describing <em>The Unreal Universe</em> as &#8220;such an insightful and intelligent book,&#8221; Bobbie says, &#8220;A book for thinking laymen, this readable, thought-provoking work offers a new perspective on our definition of reality.&#8221;</p>
<h4>M. S. Chandramouli</h4>
<p>M. S. Chandramouli graduated from the Indian Institute of Technology, Madras in 1966 and subsequently did his MBA from the Indian Institute of Management, Ahmedabad. After an executive career in India and Europe covering some 28 years he founded Surya International in Belgium through which he now offers business development and industrial marketing services.</p>
<p>Here is what he says about <em>The Unreal Universe</em>:</p>
<blockquote><p>&#8220;The book has a very pleasing layout, with the right size of font and line spacing and correct content density. Great effort for a self-published book!&#8221;</p>
<p>&#8220;The impact of the book is kaleidoscopic. The patterns in one reader&#8217;s mind (mine, that is) shifted and re-arranged themselves with a &#8216;rustling noise&#8217; more than once.&#8221;"The author&#8217;s writing style is remarkably equidistant from the turgid prose of Indians writing on philosophy or religion and the we-know-it-all style of Western authors on the philosophy of science.&#8221;</p>
<p>&#8220;There is a sort of cosmic, background &#8216;Eureka!&#8217; that seems to suffuse the entire book. Its central thesis about the difference between perceived reality and absolute reality is an idea waiting to bloom in a million minds.&#8221;</p>
<p>&#8220;The test on the &#8216;Emotionality of Faith,&#8217; Page 171, was remarkably prescient; it worked for me!&#8221;</p>
<p>&#8220;I am not sure that the first part, which is essentially descriptive and philosophical, sits comfortably with the second part with its tightly-argued physics; if and when the author is on his way to winning the argument, he may want to look at three different categories of readers &#8211; the lay but intelligent ones who need a degree of &#8216;translation,&#8217; the non-physicist specialist, and the physicist philosophers. Market segmentation is the key to success.&#8221;</p>
<p>&#8220;I think this book needs to be read widely. I am making a small attempt at plugging it by copying this to my close friends.&#8221;</p></blockquote>
<h4>Steven Bryant</h4>
<p>Steven is a Vice President of Consulting Services for <a href="javascript:popUpFat('http://www.primitivelogic.com')">Primitive Logic</a>, a premier Regional Systems Integrator located in San Francisco, California. He is the author of <a href="javascript:popUpFat('http://www.relativitychallenge.com/index.htm')">The Relativity Challenge</a>.</p>
<blockquote><p>&#8220;Manoj views science as just one element in the picture of life. Science does not define life. But life colors how we understand science. He challenges all readers to rethink their believe systems, to question what they thought was real, to ask &#8220;why&#8221;? He asks us to take off our &#8220;rose colored glasses&#8221; and unlock new ways of experiencing and understanding life. This thought provoking work should be required reading to anyone embarking on a new scientific journey.&#8221;</p>
<p>&#8220;Manoj&#8217;s treatment of time is very thought provoking. While each of our other senses &#8211; sight, sound, smell, taste and touch &#8211; are multi-dimensional, time appears to be single dimensional. Understanding the interplay of time with our other senses is a very interesting puzzle. It also opens to door to the existence possibilities of other phenomena beyond our know sensory range.&#8221;</p>
<p>&#8220;Manoj&#8217;s conveys a deep understanding of the interaction of our physics, human belief systems, perceptions, experiences, and even our languages, on how we approach scientific discovery. His work will challenge you to rethink what you think you know is true.&#8221;</p>
<p>&#8220;Manoj offers a unique perspective on science, perception, and reality. The realization that science does not lead to perception, but perception leads to science, is key to understanding that all scientific &#8220;facts&#8221; are open for re-exploration. This book is extremely thought provoking and challenges each reader the question their own beliefs.&#8221;</p>
<p>&#8220;Manoj approaches physics from a holistic perspective. Physics does not occur in isolation, but is defined in terms of our experiences &#8211; both scientific and spiritual. As you explore his book you&#8217;ll challenge your own beliefs and expand your horizons.&#8221;</p></blockquote>
<h4>Blogs and Found Online</h4>
<p>From the Blog <a href="javascript:popUpFat('http://a-cro.net/throughthelookingglass/?p=33')">Through The Looking Glass</a></p>
<blockquote><p>&#8220;This book is considerably different from other books in its approach to philosophy and physics. It contains numerous practical examples on the profound implications of our philosophical viewpoint on physics, specifically astrophysics and particle physics. Each demonstration comes with a mathematical appendix, which includes a more rigorous derivation and further explanation. The book even reins in diverse branches of philosophy (e.g. thinking from both the East and the West, and both the classical period and modern contemporary philosophy). And it is gratifying to know that all the mathematics and physics used in the book are very understandable, and thankfully not graduate level. That helps to make it much easier to appreciate the book.&#8221;</p></blockquote>
<p>From the <a href="javascript:popUpFat('http://hubpages.com/hub/Singapore_Books_Review_1')">Hub Pages</a></p>
<p>Calling itself &#8220;An Honest Review of <em>The Unreal Universe</em>,&#8221; this review looks like the one used in <a href="javascript:popUpFat('st.pdf')">the Straits Times</a>.</p>

			<content:encoded><![CDATA[<p>It is not easy to review a non-fiction book without giving the gist of what the book is about. Without a synopsis, all one can do is to call it insightful and other such epithets.</p>
<p><em>The Age of Spiritual Machines</em> is really an insightful book. It is a study of the future of computing and computational intelligence. It forces us to rethink what we mean by intelligence and consciousness, not merely at a technological level, but at a philosophical level. What do you do when your computer feels sad that you are turning it off and declares, &#8220;I cannot let you do that, Dave?&#8221;</p>
<p>What do we mean by intelligence? The traditional yardstick of machine intelligence is the remarkably one-sided Turing Test. It defines intelligence using comparative means &#8212; a computer is deemed intelligent if it can fool a human evaluator into believing that it is human. It is a one-sided test because a human being can never pass for a computer for long.  All that an evaluator needs to do is to ask a question like, &#8220;What is <img src="http://l.wordpress.com/latex.php?latex=%5Ctan%2817.32%5E%5Ccirc%29&#038;bg=FFFFFF&#038;fg=000000&#038;s=0" title="\tan(17.32^\circ)" style="vertical-align:-20%;" class="tex" alt="\tan(17.32^\circ)" />?&#8221; My $4 calculator takes practically no time to answer it to better than one part in a million precision. A super intelligent human being might take about a minute before venturing a first guess.</p>
<p><script type="text/javascript"><!--

//--></script>But the Turing Test does not define intelligence as arithmetic muscle. Intelligence is composed of &#8220;higher&#8221; cognitive abilities. After beating around the bush for a while, one comes to the conclusion that intelligence is the presence of consciousness. And the Turing Test essentially examines a computer to see if it can fake consciousness well enough to fool a trained evaluator. It would have you believe that consciousness is nothing more than answering some clever questions satisfactorily. Is it true?</p>
<p>Once we restate the test (and redefine intelligence) this way, our analysis can bifurcate into an inward journey or an outward one. we can ask ourselves questions like &#8212; what if everybody is an automaton (except us &#8212; you and me &#8212; of course) successfully faking intelligence? Are we faking it (and <a href="http://www.thulasidas.com/2008-09/zen-and-free-will.htm">freewill</a>) to ourselves as well? We would think perhaps not, or who are these &#8220;ourselves&#8221; that we are faking it to? The inevitable conclusion to this inward journey is that we can be sure of the presence of consciousness only in ourselves. </p>
<p>The outward analysis of the emergence of intelligence (a la Turing Test) brings about a whole host of interesting questions, which occupy a significant part of the book (I&#8217;m referring to the audio abridgment edition), although a bit obsessed with virtual sex at times.</p>
<p>One of the thought provoking questions when machines claim that they are sentient is this: Would it be murder to &#8220;kill&#8221; one of them? Before you suggest that I (or rather, Kurzweil) stop acting crazy, consider this: What if the computer is a digital backup of a real person? A backup that thinks and acts like the original? Still no? What if it is the only backup and the person is dead? Wouldn&#8217;t &#8220;killing&#8221; the machine be tantamount to killing the person?</p>
<p>If you grudgingly said yes to the last question, then all hell breaks loose. What if there are multiple identical backups? What if you create your own backup? Would deleting a backup capable of spiritual experiences amount to murder?</p>
<p>When he talks about the progression of machine intelligence, Kurzweil demonstrates his inherent optimism. He posits that ultimate intelligence yearn for nothing but knowledge. I don&#8217;t know if I accept that. To what end then is knowledge?  I think an ultimate intelligence would crave continuity or immortality. </p>
<p>Kurzweil assumes that all technology and intelligence would have all our material needs met at some point. Looking at our efforts so far, I have <a href="http://www.thulasidas.com/2008-07/la-logique.htm">my doubts</a>. We have developed no boon so far without an associated bane or two. Think of the seemingly unlimited nuclear energy and you also see the bombs and radioactive waste management issues. Think of fossil fuel and the scourge of <a href="http://www.thulasidas.com/2010-07/human-virus.htm">global warming</a> shows itself. </p>
<p>I guess I&#8217;m a Mr. Glass-is-Half-Empty kind of guy. To me, even the unlimited access to intelligence may be a dangerous thing. Remember how <a href="http://www.thulasidas.com/2010-06/internet-reading.htm">internet reading</a> changed the way we learned things?</p>
