 Feb 12 comment Can existing quantum computers be considered evidence for parallel universes? I'm not sure how this helps in answering the question. It seems to me that you're just making a point of interpretations not being theories by citing from arXiv (which is a great source, yet not peer reviewed). Please let me know how I misunderstood your answer. Jun 26 comment Surviving under water in air bubble @user6972, if the ocean reaches the saturation limit, isn't that also applicable to bubbles and pockets of gases? Even though bubbles are thermodynamically unstable, if saturation is reached in the ocean then it will not dissolve any more. Nov 1 comment Does the rotation of the earth dramatically affect airplane flight time? Why are you calling "Coriolis" a pseudo-force? When you calculate the derivatives, you clearly see the influence of Coriolis, hence it is a real force, not a pseudo force. Oct 22 comment Orbital radius of Geo-stationary satellite @MikeDunlavey Think of editing your comment as m is milli and M is Mega. Hence, 35mm is 35 millimeters, not mega meters ;-) Oct 17 comment Probability current @wsc Thank you for pointing that out. I think I have corrected them now, after redoing the math on paper. Oct 16 comment Young's double slit @henry, would like a proof of that the intensity of an interference $M(x,y,z)$ point of two waves of the same amplitude is $I(M)=4I_0\cos^2\frac{\Delta\Phi}{2}$ ? By rereading your question, I wonder if my answer pinpoints what you were looking for. The most important tip is to remember cosine formulas. Oct 16 comment Probability current Dear @LubošMotl, thank you for asking. In my LaTex documents, the lowercase \psi looks like this one . It is the same letter, just slightly printed differently. Oct 16 comment Probability current I got to refresh my latex ability by writing this. However, I can't seem to figure out how to write the correct Psi letter with Mathjax. In my previous (three years old) LaTeX documents, I simply used \psi without any special package. Please edit my post to correct that, thanks!
