I was searching my doubts then I saw an amazing conversation on it.

It is good for the people who wants to know physics and it's beauty

For general technical questions, post them in the appropriate technical forum (start the thread by filling out the form at the top of the forum) and include links to your reading that you've been doing and ask questions about that reading. In some of the technical forums the thread title will include a prefix that you can set to B/I/A for Beginner/Intermediate/Advanced for the level that you would like the replies to be. I is undergraduate university level, and A is graduate school level and above.

For schoolwork-related problems, post in the Homework Help forums and fill out the Template that you are provided there when starting a new schoolwork thread. That includes the Problem Statement, the Relevant Equations, and your Attempt at the Solution. Always show your work on the problem so that we can then provide tutorial help.

Enjoy PF!
