Sensory and Physical Worlds

Animals have different sensory capabilities compared to us humans. Cats, for instance, can hear up to 60kHz, while the highest note we have ever heard was about 20kHz. Apparently, we could hear that high a note only in our childhood. So, 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.

Problem of Free Will

Free will is a problem. If all of us are physical machines, obeying laws of physics, then all our movements and mental states are caused by events that took place earlier. What is caused is fully determined by the cause. So whatever we do now and in the next minute is all pre-ordained by antecedent events and causes, and we have no control over it. How can we then have free will? The fact that I am writing this note on free will — is it totally and completely determined by the events from time immemorial? That doesn’t sound right.

Data to Wisdom

When it comes to the amount of intelligence and experience required, we have a clear hierarchy from data to information to knowledge to wisdom. What we get from raw observation are just data points. We apply some techniques of aggregation, reporting charting etc. to arrive at information. Further higher level processing in revealing interconnections and relationships will give us condensed and actionable information, which we can consider knowledge. But to arrive at wisdom, we need a keen mind and years of experience, because what we mean by wisdom itself is far from obvious. Rather, it is obvious, but not easily described, and so not easily delegated to a computer. At least, so I thought. How could machines bridge the gap from data to wisdom?

Why Have Kids?

At some point in their life, most parents of teenage children would have asked a question very similar to the one Cypher asked in Matrix, “Why, oh, why didn’t I take the blue pill?” Did I really have to have these kids? Don’t get me wrong, I have no particular beef with my children, they are both very nice kids. Besides, I am not at all a demanding parent, which makes everything work out quite nicely. But this general question still remains: Why do people feel the need to have children?

Bhagavad Gita

Among the religious texts of Hinduism, the Bhagavad Gita is the most revered one. Literally presented as the word of God, the Bhagavad Gita enjoys a stature similar to the Bible or the Koran. Like all scriptures, the Bhagavad Gita also can be read, not merely as an act of devotion, but as a philosophical discourse as well. It presents a philosophical stance in understanding the world, which forms (for those from India) the basic and fundamental assumptions in dealing with life, and the unknowable reality around them. In fact, it is more than just assumptions and hypotheses; it is the basis of commonsense handed down from generation to generation. It is the foundations of intellect, which form the instinctive and emotional understanding of reality that is assimilated before logic and cannot be touched or analyzed with rationality. They are the mythos that trump logos every time.

Aging Mind

I used to have a pretty sharp mind, particularly when it came to simple arithmetic. I think age has begun to dull it. Case in point: recently I had to check a friend’s pulse rate. So I felt his pulse for 15 seconds and got 17 beats. At that point, I wanted to call out the heart beats per minute. And at that point, my mind suddenly went blank. It started going through this chain, “Ok, I got 17 for 15 seconds. So what is it for a minute? It should be, what, 60 seconds over 15 times 17. Hold it, where is my iPhone? I need a calculator. No wait, it is 17 for a quarter of a minute. So 17 times 4. Where is my calculator, dammit?!” Granted, it was a slightly stressful situation. But this is not at all the way my mind used to work.
