I'm a student of physics, particularly theoretical, with a good interest for maths, quantum mechanics (computation, optics etc), relativity and complexity.

comment Will 1 gram of matter moving at relativistic speeds completely annihilate a larger quantity of stationary antimatter?
This answer doesn't really explain why that notion of mass (rest mass) is the relevant one. Also, there is no absolute notion of velocity, but there is an absolute notion of relative velocity between the two particles, isn't there?

comment Is there a relation between quantum theory and Fourier analysis?
It's in my answer too: it's the solution to the differential equation (the second equation I wrote) "which yields..."

comment Why is classical physics not valid for a harmonic oscillator in its lowest energy state?
A large difference is in the fact that the lowest value of energy in classical mechanics is zero, while in the quantum case is not. You should state better which passages you don't understand for us to be able to answer. I don't have the book.

comment Quantum tunneling effect in a potential of the kind $V(x)=A\frac{x^2}{1+x^4}$
Sorry, I simply had misunderstood the shape of the potential, that's why I asked you "where".

comment How does a “hammer thrower” that we see in the Olympics, impart so much momentum
I wouldn't say "derived from the earth" but I guess you understood the idea. If you're satisfied, please accept the answer.

Yes, I had plotted it. My question is, it crosses the 'wall' and goes where?
