Contradictions

Life is full of contradictions.

I am attending a research retreat on mindfulness and contemplative practices at the beautiful Garrison Institute. I am learning a lot of interesting things, and meeting a lot of like-minded and excellent peoplethe kind of people with whom I could have deep conversation about the unreal nature of reality, unlike most people from other walks of life would politely and tactfully excuse themselves when I get a bit unreal.

Twilight Years

At some point in our life, we come to accept the fact we are closer to death than life. What lies ahead is definitely less significant than what is left behind. These are the twilight years, and I have come to accept them. With darkness descending over the horizons, and the long shadows of misspent years and evaded human conditions slithering all around me, I peer into the void, into an eternity of silence and dreamlessness. Es almost time.

Interpretation of Special Relativity

When we looked at Quantum Mechanics, we talked about its various interpretations. The reason we have such interpretations, I said, is that QM deals with a reality that we have no access to, through our sensory and perceptual apparatuses. Por otra parte, Special Relativity is about macro objects in motion, and we have no problem imagining such things. So why would we need to have an interpretation? The answer is a subtle one.

Mecánica Cuántica

Mecánica Cuántica (QM) is the physics of small things. How do they behave and how do they interact with each other? Conspicuously absent from this framework of QM is why. Why small things do what they do is a question QM leaves alone. Y, if you are to make any headway into this subject, your best bet is to curb your urge to ask why. Nature is what she is. Our job is to understand the rules by which she plays the game of reality, and do our best to make use of those rules to our advantage in experiments and technologies. Ours is not to reason why. Realmente.

reduccionismo

En todos nuestros esfuerzos científicos, utilizamos técnicas de alto nivel similares a comprender y estudiar las cosas. La técnica más común es reduccionismo. Se basa en la creencia de que el comportamiento, propiedades y la estructura de los objetos grandes y complejos pueden ser entendidos en términos de sus componentes más simples. En otras palabras, tratamos de comprender la totalidad (el universo, por ejemplo) en términos de menor, constituyentes reducidos (tales como partículas).

Sensory and Physical Worlds

Animals have different sensory capabilities compared to us humans. Cats, por ejemplo, can hear up to 60kHz, while the highest note we have ever heard was about 20kHz. Al parecer,, we could hear that high a note only in our childhood. Así, 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.
