श्रेणी अभिलेखागार: भौतिकी

भौतिकी मेरा पहला प्यार था. इस श्रेणी में मेरे दिल के पदों निकटतम शामिल. बीस साल अब से, इस ब्लॉग बचता है, इस श्रेणी में शायद मेरी सबसे ज्यादा टिकाऊ अंतर्दृष्टि का आयोजन करेगा. और दो सौ साल अब से, मैं सभी को याद कर रहा हूँ अगर, यह इन अंतर्दृष्टि के लिए किया जाएगा; नहीं मैं हूँ व्यक्ति की तरह के लिए, मैं बनाने के पैसे, न ही कुछ और. केवल मेरी पहली और आखिरी प्यार के लिए…

कण और सहभागिता

हाल ही में, मैं कणों और मेरी बेटी के सहपाठियों को बातचीत जो एक यात्रा पर योजना बना रहे थे Desy करने पर एक भाषण दिया, जर्मनी और यह सब क्या था की एक विचार है चाहता था. इस तरह के अपने पहले बात करते हैं जैसे, मैं थोड़ा नर्वस क्योंकि मैं नहीं जानता था क्या स्तर, और पृष्ठभूमि, मैं कम से बात खूंटी चाहिए. मैं यह भी बुनियादी बनाने के लिए नहीं करना चाहता था, मैंने सोचा कि जो समय की बर्बादी होगी. न ही मैं यह भी तकनीकी बनाने के लिए करना चाहता था, जो भी यह एक अलग तरह से बेकार करना होगा.

Sensory and Physical Worlds

Animals have different sensory capabilities compared to us humans. Cats, उदाहरण के लिए, can hear up to 60kHz, while the highest note we have ever heard was about 20kHz. जाहिर है, we could hear that high a note only in our childhood. इतना, if we are trying to pull a fast one on a cat with the best hifi multi-channel, Dolby-whatever recording of a mouse, we will fail pathetically. It won’t be fooled because it lives in a different sensory world, while sharing the same physical world as ours. There is a humongous difference between the sensory and physical worlds.

What Does it Feel Like to be a Bat?

It is a sensible question: What does it feel like to be a bat? Although we can never really know the answer (because we can never be bats), we know that there is an answer. It feels like something to be a bat. खैर, at least we think it does. We think bats have चेतना and conscious feelings. दूसरी ओर, it is not a sensible question to ask what it feels like to be brick or a table. It doesn’t feel like anything to be an inanimate object.

The Origins of Gods

The atheist-theist debate boils down to a simple question — Did humans discover God? या, did we invent Him? The difference between discovering and inventing is the similar to the one between believing and knowing. Theist believe that there was a God to be discovered. Atheists “पता” that we humans invented the concept of God. Belief and knowledge differ only slightly — knowledge is merely a very very strong belief. A belief is considered knowledge when it fits in nicely with a larger worldview, which is very much like how a hypothesis in physics becomes a theory. While a theory (such as Quantum Mechanics, उदाहरण के लिए) is considered to be knowledge (or the way the physical world really is), it is best not to forget the its lowly origin as a mere hypothesis. My focus in this post is the possible origin of the God hypothesis.

9/11 Debunkers

व्यक्तिगत रूप से, one of the main reasons I started taking the conspiracy theories about 9/11 seriously is the ardor and certainty of the so-called debunkers. They are so sure of their views and so ready with their explanations that they seem rehearsed, coached or even incentivized. Looking at the fire-induced, symmetric, and free-fall collapse of WTC7, how can anyone with any level of scientific background be so certain? The best a debunker could say would be something like, “हाँ, the free-fall and the symmetry aspects of the collapse do look quite strange. But the official explanation seems plausible. कम से कम, it is more plausible than a wild conspiracy by the government to kill 3000 of our own citizens.” But that is not at all the way they put it. They laugh at the conspiracy theories, make emotional statements about the technical claims, and ignore the questions that they cannot explain away. They toe the official line even when it is clearly unscientific. They try to attack the credibility of the conspiracy camp despite the obvious fact that it has the support of many seasoned professionals, like architects, physics teachers, structural engineers and university professors.

Atheism and Unreal God

The only recourse an atheist can have against this argument based on personal experience is that the believer is either is misrepresenting his experience or is mistaken about it. I am not willing to pursue that line of argument. I know that I am undermining my own stance here, but I would like to give the theist camp some more ammunition for this particular argument, and make it more formal.

9/11 – Motives for Mass Murder

In the first post in this series, we saw that 7 World Trade Center building was the smoking gun of a possible conspiracy behind the 9/11 attack. The manner in which it collapsed and the way the collapse was investigated are strong indications of a conspiracy and a cover up. हालांकि, when I first heard of the conspiracy theory in any serious form, the first question I asked myself was why – what possible motive could any person or organization have to commit mass murder at this scale? I honestly couldn’t see any, and as long as you don’t see one, you cannot take these conspiracy theories seriously. जरूर, if you buy the official story that the conspiracy actually originated in Afghanistan among terrorist monsters, you don’t need to look for any rational motives.

Atheism vs. God Experience

I have a reason for delaying this post on the fifth and last argument for God by Dr. William Lane Craig. It holds more potency than immediately obvious. While it is easy to write it off because it is a subjective, experiential argument, the lack of credence we attribute to subjectivity is in itself a result of our similarly subjective acceptance of what we consider objective reason and rationality. I hope that this point will become clearer as you read this post and the next one.
