Bill, thanks a lot for the elaborate answer. That really helps. BTW, may I know if there is a comprehensive source (book / site) covering other areas, leading to the current understanding as you explained ?

Only reasoning that I used was since "Temperature is a measure of the average translational kinetic energy of the molecules of a substance. " , we have more translation in liquid than solid. Hence it is counter-intuitive. I know there is something more to it than that... :)

Both these "definitions" are counter intuitive. Obviously the KE of liquids is more than that of solids, at the SAME temperature. How can this be explained ?

Hello, this might be a basic question. In feynman diagram's we represent the positron as traveling backwards in time. Is that correct ? How do we interpret this ?

It should be n1 + n2. Why do you think it should be less.

Collapsing of wavefunction is a mathematical concept. It is a term used for saying probability of object, in your case photon, was something in both the paths before detection- however now that it is detected probability is 1. So mathematically it is like collecting probabilities from different...

Guess these are not right questions..

Folks, any thoughts on my questions below ?

ok. I will try and explain why I have the below questions. May be someone can throw some light on this. I am following the argument of Bell's theorem with Stern Gerlach Analyzers (SGA) and silver atoms (Daniel Styer). In this first probablilty that is calculated is for a simple setup where...

Any links / sources where some of these could be ?

I think we have to let go this with the introductions of wave particle duality .. which is also not a right way of putting it. wavicle was term that was invented, but never stuck. Essentially it means at micro-level you have two ways of looking at things , material (particle) or non-material...

Zonde, about the first question, say a torch or a laser light when it comes out of the source, does not know the destination. However at the macro level we know where the light is going to reach. If the photons took any random path, we wouldn't be able to predict the destination - would we ?

Excited to see so much discussion. I agree with arkajad that we can calculate how it collapses. But my questions were : 1. Photon can take any path,can go even outside interferometer, and not necessarily a straight line. Is this correct ? 2. Is the description 'photon takes both...

In theory, yes we would have the equation of motion and we could calculate position and momentum my using the equation of motion. But HUP talks more about uncertainilty measurement rather than calculation. so even if we have two sets of apparatus one to measure position and one momentum...

This is with respect to the Elitzur–Vaidman bomb-tester. Where the of wavefunction of photon is going to collapse is not known accurately. It is said that a given photon takes both paths in the Mach-Zehnder interferometer and MAY collapse if it meets an obstacle (Bomb). few questions: 1...
