Got it. Thank you for your help :)

Many Thanks :) The confsion is solved. But, what kind of generality does the Schrödinger UR has? In other words, what distinguishes it from Heisenberg's UR?

The general Uncertainty Principle is written in Griffiths' Intro to Quantum Mechanics 2nd Ed. Section 3.4, Page 109, Eq. (3.139) without dependence on the wave function itself. While it is written in R. Shankar's Principles of Quantum Mechanics 2nd Ed., Section 9.2, Page 239, Eq. (9.2.12) with a...

Thanks a lot :)

Thanks a lot for your help. I got it.

Why do Complex Numbers arise in Quantum Mechanics' computations? What kind of physical significance do they carry? Someone told me to read this paper: W E Baylis, J Hushilt, and Jiansu Wei, Why i?, American Journal of Physics 60 (1992), no. 9, 788–797. But I found it difficult for me to...

Thanks a lot guys for your help. I will try to handle it :)

My problem is that I can't even check whether my answers are true or false

- Griffiths offers a small number of problems at the end of each section (sometimes 2 or 3 problems only) but not all of them are quite hard. And some of them are marked so that every reader should do them carefully. - No. I don't know anybody to help me. It is even worse to tell you that...

Aha. I think that I understand them clearly but I just don't spend time studying them carefully -I mean the derivations-. But I think I have to spend more time on them. Thanks for help :)

Hi. I'm a self-learner, and I'm doing an introductory QM from Griffiths. My question is should I memorize all the derivations and proofs in the book or I just have to memorize the final results? Another point is that I have nobody to ask about my solutions to problems or to help me in the hard...

If I got a good score in GRE, can I get into graduate school without even having a bachelor's?

May be you are right. But I've just worked it using trigonometric substitution using x = tanθ and it worked correctly .. Maybe there exist a way to find it using IBP but it's a hard way and there is no use for it if there is an easier way :)

Thanks a lot guys for your help and I'm sorry for replying after a long period but I didn't access the forum through those two days :)

I tried this one and it didn't work .. In the sections I've studied in the previous two days I learned trigonometric substitution and miscellaneous substitution; I think I have to try working this problem with those techniques
