There are, but I don't like them.

Hi There! I am exploring career options in Nuclear Physics, exactly speaking, Theoretical Nuclear Physics. One of the ways to pursue a career in the field is of course in the academia, as a Professor and Researcher. But as we know, sustaining in the academia is not an easy job. I was wondering...

The only application I find in studying mathematics or physics is that *I love them!*. What could be better?

My Solution to previously unsolved High School and First Year University Question 3: My solution to Question 6: We can start forming a nested radical expression for ##x##: $$|x|=\sqrt{x^2}\\=\sqrt{1+(x-1)(x+1)}\\=\sqrt{1+(x-1)\sqrt{1+x(x+2)}}\\=\sqrt{1+(x-1)\sqrt{1+x\sqrt{1+(x+1)(x+3)}}}$$ In...

Thanks a lot, Sir!

I am a tenth grader, and a newbie to Advanced Calculus. While working out problems sets for Gauss's Law, I encountered the following Surface Integral: I couldn't attempt anything, having no knowledge over surface integration. So please help.

Hello. Well, each and everyone of us know that Like Charges repel, while unlike charges attract. That's a normal high school physics fact. But what's the reason for that? Is it just an experimental fact, or even does have theoretical significance? Please do help. Thanks a lot Swapnil Das.

Thanks, wonderful explanation!

Are they at the same potential? Is it the same principle out there?

Thanks for your valuable reply!

But how does the method assume that they are at the same potential?

Hello. Modern Physics explains Gravitation in two general ways: In accordance to the General Theory of Relativity, Gravitation is thought of as an effect of the curvature of space-time continuum. This results in the formation of the recently and famously detected Gravitational Waves. Quantum...

I have been studying the method of symmetry from some days, which essentially reduce the effort needed for the evaluation of equivalent resistances. My textbook states: Points having symmetrically located about initial and final points have the same potentials.So, the resistances between these...
