Thanks to all of you. If you find anything out, I would appreciate any additional information. I have been told that if the spin allignment is retained that there would be no interference pattern even though no attempt is made to detect which slit the electrons pass through. I can't figure...
I don't understand how going past the biprism would re-align the electron. Can you explain that? Are you saying that there is no way to do the double slit experiment using eletrons with aligned angular moment and preserving that angular moment throughout the course of the experiment?
Thanks...
Can anyone direct me to any version of the double-slit experiment which used only electrons with aligned spin axes? If you can't direct me to an experiment, can you postulate how or if the double-slit experiment might be different using such electrons?
Thanks!
Maybe I wasn't very clear in my language. Sorry. I'm simply saying that if we lived in a world where the quanta that compose the macroscopic world (quanta of energy and matter) were bound together in such a way that changes of state didn't occur, changes of position could still occur. Such a...
That's fair. If I knew how, I would shut up and calculate! But being a very poor mathematician, I must resort to questions. Perhaps I'm trying to find sense and meaning in a physical phenomenon which by nature is inexplicable. Is that what your trying to tell me?
There was a time when people a lot more qualified than me said the Earth was the only valid frame of reference. So the age of geocentricity was born. It started with Ptolemy (a most qualified and eminent scientist of the 2nd century A.D) and lasted for over 1500 years because everyone believed...
On a more speculative note, I can imagine a universe in which there is no dimension of time. Let me explain first by describing two different kinds of change that occur in classical spacetime. The two kinds of change are changes of position and changes of state. In spacetime, a man can move...
Observation provides us with experience in three dimensions of space and one dimension of time, but science has suggested that there are other dimensions in which nature operates, dimensions so exquisitely small that all of us will be very lucky if in our lifetimes human eyes pierce their...
Does Roger Penrose' twistor space play a role in this discussion? Here is what Lee Smolin says about twistor space in his book The Trouble with Physics, pg 244: "More specifically, you can make a new space, consisting of all the light rays in spacetime. You can then translate all of physics...
Thanks for the levity, Kev. I feel like that almost every morning! Perhaps the condition you describe is more common than those who commented before you have let on! The reason I asked the question is because it seems to me that velocity we call c is something we take terribly for granted...
Thanks! I guess in the context I'm trying to understand the electron makes contact with the wire. What about the second question. Is the electron influenced in any way by the wire loop that has been proven by experiment (does it alter or change the electron or any of its properties)?
Thanks for your response. I didn't take your response as critical. I'm grateful for the insight. Perhaps if Kaluza had been right and light were a phenomena of 4 spatial dimensions my question would make more sense. I'll think about it some more and see if I have any other questions. Thanks...
According to Einstein's relativity theories, each observer is afforded a frame of reference which can be considered central and stationary. What would the universe look like to the frame of reference associated with a photon observer. Would all things be moving past the photon at the velocity...
Does the electron actually make contact with the wire loop? If not, does the wire loop influence the electron in any way that can be proven by experiment? Can you spell out CCD for me?
