Postulates Definition and 62 Threads

I have the mathematical background to compute things in quantum mechanics. If you give me a standard QM problem to solve I could probably do it. However, I have an extreme lack of understanding of why the postulates of QM are set up the way they are - that the complete description of a particle...

Hi all I was recently told that certain postulates of SR are equivalent or one can be derived from the other. Namely 1) The speed of light in vacuum is constant and is independent of the speed of emitting body; 2) The speed of light is impassable limit; I did some search and found quite...

In my course of modern Physics one postulate i read is "Associated with any particle moving in a conservative field of force is a wave function which determines everything that can be known about the system" A question arised in my mind is if the particle is moving in non conservative field...

Hello, recently I got this question on my Logic Design course exam, Prove the following theorem using postulates: X OR 1 = 1 I explained it using a simple argument, a variable can be considered as a switch in a circuit, if it is 1 then the switch is on, if it is 0 then the switch...

Hi everybody, First, I want to excuse myself for the mistakes in this message (and in the others that I will write), because I am not an english speaker and I am not accustomed to write in english. It is the reason why I come here, to improve my English :smile: . If I make a big mistake, I...

The usual foundation for deriving SR is the constancy of the speed of light. Are there other ways to derive SR, and eventually some more general? Have you ever read something about that? Thanks, Michel

I had a search for an answer but I turned up nothing, if this has been covered before could someone point me in the right direction? To the question. I'm studying QM at the moment but I'm having trouble with two of the postulates. Is the constraint that the wavefunction must be continuous...

Hello everyone. I've just received my gr 12 physics textbook today and began reading the chapter on Special Relativity, because I find it fascinating. So I'm new to the topic, please bear with me. The first postulate states that "the laws of physics have the same form in all inertial...

What I've read on special relativity has built it up from its two postulates, the principle of relativity (in the restricted sense) and the constancy of the propagation of light in vacuo. But I haven't seen general relativity's postulates in such a concise listing. I assume the equivalence...

What is "Condition Postulates" ? I'd be happy if someone explains.. Thanks.

could someone be kind enough to explain to me why the fundamental postulates of special relativity introduced thanks

Hello, Id like to ask any of you to suggest to me a book which can describe SR & GR straight from its postulates all the way to the forumals used through math but also through detailed explanations. Does such a book exist ? I have almost complted reading elegant universe and it is pretty...
