Hi all. I'll starting a little research for my college assignment. But I need to discuss a few concepts in Quantum Mechanics [sorry for my english]. 1. I want to analyze perturbation effect that suffered by an ion. Is Rayleigh-Schrodinger theory suitable for this problem? if not, which...

Thank you sir

I know some people that good in both physics and programming. Some game programmers have skillful in geometry, coordinates transformation, and some related stuff from mathematics and physics fields. AI programmers, computational physicists?

Hi all, I'm trying to self-learn about chaos, fractal, or anything that correspondence to random analysis (maybe with some material from statistical physics). Anyone know what the best textbook for these fields?

1. Mathematics. First, try to solve diagnostic test in "Calculus" by James Stewart (https://www.amazon.com/dp/0538497815/?tag=pfamazon01-20). You will find useful material for learning some basic stuff. If you can solve all of the questions, You can continue learning mathematics with this...

Hi all, I just want to know that my relation is correct or not? \frac{1}{Z}\frac{dZ}{d\beta} = \frac{d}{d\beta}\int\frac{dZ}{Z} = \frac{d}{d\beta}\left(\ln Z\right)

Thank you for quick replay. Yes, your relation is correct too. If this is a chain rule, so can i write them like one in the first thread?

I have an equation like this, \frac{dZ}{zD\beta} = \frac{d}{d\beta}\ln Z, is it from \frac{d}{d\beta}\frac{dZ}{Z} or from...? How we can prove this relation?
