I just finished my first term as a professor at Singapore Management University. I taught an undergraduate course called Computer as an Analysis Tool, which is on business modelling and data-driven decision support. I had about 130 학생, in three sections of three classroom hours each per week. I have to say the whole thing was a very enriching experience. 물론, the reasons behind this statement will be expounded on, theorized and hypothesized – this is Unreal Blog, 결국.
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.

입자와 상호 작용에 포스트 시리즈는 내가 원하는 것보다 더 조금 된 이후, 나는 그것을 깰 것이라고 생각. 의는 물질의 구조를 이해하는 것이 필요합니다 현대 물리학의 요점을 되풀이 시작하자.
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.
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.
우리는 아인슈타인과 특수 상대성에 대해들을 때 (또는 상대성의 특수 이론, 실제 이름을 사용), 우리는 유명한 생각 방정식, 그리고 쌍둥이 역설처럼 이상한 일. 그 일이 모든 진실하고 중요하지만, SR이 해결하려고하는 문제는 완전히 다른 하나이다. 물리학의 기본 원리를 방어하기위한 시도이다.
