I'm presently a physics major, and futurely (yes, I know it's not a word) a physics teacher. I've never wanted to do anything else. I just love physics, pure and simple.

comment Reunion condition in the Twin Paradox
The condition for reunion is that both twins have the same spacetime coordinates. This is true whether you are talking about Newtonian physics or relativistic physics.

comment Why aren't quarks free?
Your first question is maybe one of the top ten unsolved problems in physics at the moment. No one knows yet. Some physicists are hopeful that string theory will solve answer this question, assuming we ever figure out how to test string theory.

comment Should I learn Classical Physics if I want to learn Quantum Physics?
A better question is CAN you learn quantum physics without learning classical physics?

comment How is a standard unit divided into equally smaller or fractional units physically/experimentally?
The OP should really consider fleshing out this question some more, to better facilitate a more targeted response. The yearly publications from the NIST on measurement standards is a testimony to just how much can be written on the subject if a person is of a mindset to do so.

comment What is empirical mean of centripetal acceleration
Suppose you have a point moving along a circle. The point's distance from the center never changes, yet it's velocity is non-zero. What gives?

comment Why is a proton assumed to be always at the center while applying the Schrödinger equation?
@RajeshD The assumption that the proton is stationary is just an approximation used since protons are about 2000 times as massive as the electrons and 2000 is approximately infinity.

comment Correction to Period of a Pendulum
The variable $\theta$ represents the angle of the pendulum as a function of time. $\theta_0$ is just the initial angle at $t=0$.

@Jitter Yes, it's quite relevant to that question as well! In fact it's almost worthy of being submitted as an answer.

comment Doubt regarding inclined plane in feynamn lectures
@user34304 As with the Bible, it's much more convenient to cite the book, chapter, and verse when you're trying to locate a passage in the Big Red Books. E.g., the 'Gravitational potential energy' is section 2 of chapter 4 of Book I, so you'd write (I.4:2) ;)
