 Apr 19 comment What is wrong with the De Broglie–Bohm theory a.k.a “Causal Interpretation” of quantum theory? @dmckee Clarification: as OP of earlier question, I had asked a plain question to correct my understanding from a reading. It did not ask for a philosophical discussion, and what happened later was really beyond me. Apr 19 comment Phonons in non-crystalline media @anna v it is incorrect that frequency can take Any value.

Check edit in my answer. Apr 18 comment If I put a ping pong ball in a vacuum, would it pop? @NickLarsen now that will involve quantitative calculations. You must know the tensile strength of the material that makes the shell of ball. If the pressure inside is approximately atmospheric so it doesn't collapse or pop in air, then you would need to know the pressure of the partial vacuum (0 Torr in case of full vacuum, if that's possible), and find if the material can withstand such a pressure difference. In general, you can safely say that normal materials such as plastic wouldn't withstand the pressure gradients between say, a sputter ion vacuum on one side and air. Apr 18 comment If I put a ping pong ball in a vacuum, would it pop? if it has air inside, yes.

I was copy pasting my intitial equation's latex to be quicker, and I had left the $i\hbar$ factor sticking to the $\partial_t(\cdots)$ so thanks :-P Apr 18 comment How do I correctly interpret $\rho = \psi_1^* \psi_2$? @David yup.. done!

I will work out the steps for full scrutiny in another edit.

But i noticed that the quantity $\rho$ appeared to satisfy the continuity equation, and the interpretation says that it must be the probability density, albeit some strange kind of probability density.

I was confused because I tried to technically interpret the word correlation. Apr 16 comment How do I correctly interpret $\rho = \psi_1^* \psi_2$? @marek then what would be an integral representation of $P_{1 \to 2} = {\left \Vert \left < \psi_1 | \psi_2 \right > \right \Vert^2 \over \left \Vert \psi_1 \right \Vert^2 \left \Vert \psi_2 \right \Vert^2}$ Apr 15 comment How do I correctly interpret $\rho = \psi_1^* \psi_2$? @Marek thanks. one further question, does it make sense to say that $dP_{1\rightarrow 2} = \int (\psi_1^* \psi_2)^* \psi_1^* \psi_2 d^3r$... what does a probability of transition mean in a small volume element. Because states usually means a specifications of the values of $\psi$ in all points in space.. then how can we have a probability of state transition in a small volume??
