yes neighbour complaining and this is in the middle of the day! i already have the board on a portable darts stand so nothing goes through the wall. I have noise absorbing panels on the wall which takes the sharp echoy part of the sound away. But the people downstairs still moan. However looking...
Thank you for the reply. I was afraid people would think i was trolling but actually I am finding it a tough problem. The narrow point was not something i thought about, thanks. I guess in practice it means keep the darts ultra sharp. Will be interesting to actually test the difference between a...
so what started out as a quick project to silence my dartboard has ended up wondering what would be the physics involved in creating a silent dartboard. It has to use a standard board so the board can't be modded in terms of its materials. Now i guess the answer is to dissipate the energy as far...
but if the event is zero secs all observers would see the event the same. Since the point is you are not observing both particles at the same time, just observing one particle at which point you instantly know the state of the other. So i don't see how frame of reference changes anything.
yes but once you define simultaneous as zero elapsed time and not an approximation then you are stuck. You can never demonstrate this experimentally because you have no way to measure it.
So much like string theory its all works mathematically but is untestable and fails Newtons grounds for...
i think the question is answered by the continuous use of the phrase "within precision limits". Therefore it is untestable and it is not possible to say any two events to any observer in anyone time frame are simultaneous where time elapsed equals zero.
its hard to know which forum to post in. My question is whether two events can ever be said to be simultaneous and if so how would that be proven since its not measurable.
if an event happens at the exact moment of another for a single observer, what does instantaneous mean? This stems from a question i posed about the speed at which two entangled particles collapse into one definite state when one is measured. It got m thinking what does zero time and...
when one entangled particle is measured and its state known the other particle of the entangled pair is described instantaneously collapsing into the same state. What exactly does this mean? does this mean zero time for the pair to take on the same state? I thought the minimum amount of time you...
yes I am afraid it does. its the Schrödinger equation and feynmans every possible path.
quantum mechanics doesn't make sense but it works. How can something be in more states than one at the same time? Its beyond our logic but its the way it is.
the maths describes what's going on, it doesn't tell us why, that's philosophy. I am interested in the maths and the picture of quantum mechanics that describes to us. Knowing the position does not change the structure, there is no structure. Knowing gives us a single state from every possible...
perhaps i did and you didnt think about the reply long enough because the reply wasnt the one you wanted. If you have a point to make it would be easier to just come right out and say it rather than ask me a series of questions we both know the answer to.
well not much to think about here. One is a wave formed of molecules, the other is a probability wave that exists/doesnt exist in every possible state until the information of its precise location or speed could become available. At that point it collapses into a single state which cannot be...
