Jun 17	revised	How can I stand on the ground? EM or/and Pauli? deleted 12 characters in body
Jun 17	comment	How can I stand on the ground? EM or/and Pauli? Here's another link.
Jun 17	comment	How can I stand on the ground? EM or/and Pauli? I posted that link almost two years ago, I don't remember needing a password back then. I can try to update the link though.

Jun 12	comment	Transforming a sound wave into a literal light wave. Is it possible? Something like sonoluminescence?

Jun 3	comment	Why do rockets accelerate fastest horizontally? The other possibility is that you just are not reporting the question correctly to us.
Jun 1	comment	How to prove Galilean invariance? Your mistake is simply that you assume that $F$ and $a$ have to transform according to $G$ under Galilean transformations. That is not true however. $F$ and $a$ do not change under translation and boosts. Only under rotations.
Jun 1	comment	How to prove Galilean invariance? @Wox: The general case can be deduced from the special case. If you show separately that Newton's equation is invariant under rotations and under translations, then it's just a matter of combining the three types of transformations. But this follows because of the fact that we are working in a group.
May 30	comment	What do scientists believe about existence in dimensions? This is just a very bad question. It makes no sense, is so rife with confusion that the best thing we could possibly do is to tell you to go read at least a popular book on the subject like a book by Stephen Hawking or Brian Greene.

May 29	answered	Where can I find beginner's information about quantum mechanics?
May 29	comment	About Susskind's claim “information is indestructible” This is tied to the unitarity of QM evolutions.
May 27	comment	Given entanglement, why is it permissible to consider the quantum state of subsystems? Best answer here. Deserves more points.
May 26	comment	How to prove Wick's Theorem (Zee's eq. I.2 (16)) via Gaussian integration? Just derive your expression a second time w.r.t. $J_m$. Already you should see that there will be a non-zero term. So you shouldn't expect the entire expression to be zero.
May 12	comment	How Light or Water Intensity is equal to square modulus of wave function of Light or Water Waves $I=\|\psi\|^2 \,$? The short answer is: the wave function is the amplitude, not the intensity. The square of the wave function is the intensity. Intensities don't add up, amplitudes do. So $I=I_1+I_2$ is in general wrong.
May 10	comment	Why did Feynman's thesis almost work? Very nice question. I've read more in detail about the Feynman-Wheeler approach in the book "Action at a Distance in Physics and Cosmology" by Fred Hoyle and Jayant Narlikar. They build up a theory of gravity in the same spirit as the Feynman-Wheeler theory. It does not seem to fit observations though.
