What she actually said was that you had to address them using a respectful form of “you,” which doesn’t make any sense in English, but may work in Hindi or French. It worked poetically well in Malayalam. I was reminded of this maternal pearl of wisdom recently when I was watching a movie with my son.

모순,en

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 people – the 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. 그것은이다 almost time.

Interpretation of Special Relativity

When we looked at Quantum Mechanics, we talked about its various interpretations. The reason we have such interpretations, 내가 말했다, is that QM deals with a reality that we have no access to, through our sensory and perceptual apparatuses. 한편, 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.

Speed of Light

The speed of light being a constant sounds like a simple statement. But there is more to it, quite a bit more. Let’s look at what this constancy really means. 언뜻, it says that if you are standing somewhere, and there is a ray of light going from your right to left, it has a speed C. And another ray of light going from left to right also has a speed C. 지금까지, so good. Now let’s say you are in a rocket ship, 아래 그림과 같이, moving from right to left.

상대성의 특수 이론

우리는 아인슈타인과 특수 상대성에 대해들을 때 (또는 상대성의 특수 이론, 실제 이름을 사용), 우리는 유명한 생각 E = mc^2 방정식, 그리고 쌍둥이 역설처럼 이상한 일. 그 일이 모든 진실하고 중요하지만, SR이 해결하려고하는 문제는 완전히 다른 하나이다. 물리학의 기본 원리를 방​​어하기위한 시도이다.

Quantum Field Theory

In this post on Quantum Mechanics (QM), we will go a bit beyond it and touch upon Quantum Field Theory – the way it is used in particle physics. In the last couple of posts, I outlined a philosophical introduction to QM, as well as its historical origin – how it came about as an ad-hoc explanation of the blackbody radiation, and a brilliant description of the photoelectric effect.
