What do you mean by "it is not possible to erase the information well enough to sense this without coincidence counting"?
You are right about the diagram, also. Cheers.
I have a related question, I think. I have been reading about the Scully-Druhl experiments where the photons are directed to down-converters, which create a "signal" photon and an "idle" photon, and in which it appears that the idle-photon gives information about which path the signal photon...
I see what you mean. But let's assume it is a simple set of states that I have complete knowledge of, and I can predict a future state with complete accuracy as I have managed to discover all the laws of physics. This then removes the impediments of unknown elements as far as I can see...
This is probably the stupidest question I have ever asked, but it is bugging me and I am looking for an illuminating answer - not one that simply tells me I have the wrong idea, but one that explains in what way I have the wrong idea.
I can, based upon some knowledge of initial conditions and...
Thank you Chronon, I think I understand a bit more because of your post. To fully try and grasp it, I am going to try and rephrase the question as best I can (or ask a new but related question, rather).
If we take a sequence in time in which it is impossible to determine the next state of a...
Thank you for your reply.
I was specifically curious about time reversal and objective randomness, which I understand is a phenomenon of quantum physics and not classical physics. I did not really know that other systems were not time-invariant: I thought that they just appeared that way on...
I am not a physics student - I am a science fiction writer. But an idea is puzzling me, and I will attempt to convey it. However, I apologise if my terminology or an incorrect understanding of things makes my question unclear.
Firstly, I am under the impression that the laws of physics do...
