I do not understand what do you mean that if you measure the position with arbitrary precision you can never say the particle IS in the position you measured.

Hi. Actually as I understood your question is about the interpretation of wave function in quantum physics. Let's consider a single particle which can move only in one direction for example. The motional state of the particle can be described giving a wave function Psi(x,t) at a certain time...

The Ehrenfest theorem states what are the equation of motion for the mean value of observables like Position and Momentum The Heisenberg picture moves the time dependence of the system to operators instead of state vector. So it provides the equation of motions for the operators not for their...

As I said i do not take anything for granted. So I will be pleased if you can indicate me some reference about. Something a priori against special relativity: do you think it wasn't a barrier the concept of absolute time? It wasn't a barrier thinking about non-classical, non-local...

I do not take anything for granted. Sorry if you understood that from my words. The only thing I believe is that you never have to exclude things a priori. And stating that science has limits is excluding something a priori. The greatest revolutions in science happened thanks to people who...

That's not a proof :) You ask me to read books written by people which in this era believe that :) Nothing can stop science growth and understanding of the world...of course it is possible that we will never reach the limit, I do not know the answer but as a scientist (maybe a beginner but still...

Well not now for sure, but science has the power to evolve also at a level which now we call "philosophical or metaphysical" . Anyway let's talk about that some years from now :)

Nice questions...but unfortunately I think scientific world needs many other decades to get answers to them. Or probably...it will never answer

Hi i do not know what does it mean partial measurement... up to my knowledge, Alice simply makes a measurement on her qbits in order to find out in what of the 4 Bell states they are. Then I think the protocol contoinues as wikipedia says. So Alice and Bob comunicate through a classical...

Hi, I'm a new user so this is my first post. I say sorry in advance for my english. As already mentioned by Fredrik and partially by Minich (in the sense that he gave an example of topic in which you use the trace), the operation of trace is very common in every field of physics in which you...
