Where can I find the equations of general relativity and Schrodinger's equation?

Question

I want a detailed description of the equations of general relativity and Schrodinger's equation.How can I find that?

Answer 1

Get a text book. "Modern Physics" by Serway was pretty good.

The equation of general relativity is fairly simple to begin with thou: E = Em +Ek, where E is the total energy, Em is the rest mass/energy and Ek is the realivistic kinetic energy function, which has characters I do not have on this keyboard.

Shrodingers equation requires a bit more explaination... it is an equation with an infinite number of solutions, and an infinite number of wrong answers... kinda annoying. The answers are all probability functions, and a good background in linier algebra and multi-variable calculus is necessary to understand it at all. The significance of the equation, however, can be summed up fairly nicely. While in classical mechanics, the idea was to give a definate answer, relying on our knowelege that if something is behaving this way now, it will behave that way later also, we could accurately predict where something would be providing nothing changed. This is not the case in quantum mechanics. The analogy of Schrodinger's cat is often used to describe how a particle can exist in multiple states at the same time just because we do not know what state it is in.

The implications of the Schrodinger equation are thought provoking, actually solving it is extremely difficult.

Answer 2

You could search wikipedia, which will give you some brief background and both the Einstein and Schroedinger wave equation:

http://en.wikipedia.org/wiki/Einstein's_field_equation
http://en.wikipedia.org/wiki/Schr%C3%B6dinger_equation

But to understand their context and meaning would take more serious study.

For General Relativity, there is "Gravitation" by Misner, Thorne and Wheeler as the canonical text. Probably easier, there is Bernard Schutz's book which is pitched at undergraduates.

To understand Quantum Mechanics, there's a book by Anthony Sudbery that is decent; Liboff and Griffiths were still big with the undergraduates last I checked.

Answer 3

Trial and mistake is a undesirable thank you to get a formula. although there have been situations the place physicists used formula that they arrived at by utilising trial and mistake, and located that they worked, yet in elementary terms later did mathematicians in the past teach them suitable. they could plot archives and consider out to discover an equation that seems to greater healthful, or further word family members between numbers that take place in experiments. With math although, you will be a hundred% specific approximately each and everything, and derive each and everything from contemporary issues that are primary. some formula, like C = ? d, are definitions as a results of fact consequently ? itself is rather defined as C/d. yet a formula like A = ? r^2 had to be derived from utilising different mathematical homes till a formula for expressing the section replaced into got here upon.
