S's equation is just that; an equation. What about the equation allows your equation to have the meaning you ascribe to it? AG * *Schrodinger's equation uses complex numbers to deterministically derive a quantum wave. That quantum wave must be a real thing because, thanks to experiment, we know for a fact that the square of the absolute value of it corresponds with something real, that is to say something that has a possibility of being observed. For example, Schrodinger's equation says that a system consisting of a neutron decaying into a proton, an electron and an antineutrino has a wave function that is NOT zero and therefore can be observed, but a wave function that has an electron turning into a proton has a wave function that is zero and therefore can NOT be observed by anyone anywhere. * *Please note that if Schrodinger's equation says that something can be observed, that does not necessarily mean that YOU can observe it, nor does it mean you know somebody who could observe it, and it doesn't even mean that it's possible for you to know somebody who could observe it. It only says that the event can in theory be observable by somebody.* *This is not what S's equation says. For example, in a slit experiment, on a single trial it just tells us the probability of every possible outcome, not that every possible outcome MUST happen.* So if it wasn't so, repeating the experiment shouldn't give interference patterns. At least for non-relativistic QM, S's equation presumably contains all information, including that for interference. So a single measurement doesn't negate those infinitely many possible outcomes, inclusive of interference. Clark's persistent and unshakeable error is to add a postulate to the equation which is nowhere in sight; namely, that every possible outcome MUST occur somewhere, which is where Many Worlds is postulated. AG * You've added that to what the equation says, but are not aware of having done so, or won't admit it. AG* *By the way, if you ever want to end this conversation all you need to do is talk about cults or Trump physics. * *John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* *>Whichever turn you take, there exists an uncountable set of paths, corresponding to the set of possible curves* *Maybe. Maybe not. There is no doubt that mathematically the set of all possible curves is uncountably infinite, but we're talking about physics not mathematics, so the answer is not clear at all. There might be an uncountably infinite number of paths, there might be a countably infinite number of paths, there might only be an astronomical number to an astronomical power FINITE number of paths; it all depends on if time and/or space is continuous or discrete. Schrodinger's Equation is an agnostic on that question, and so is Many Worlds.* -- You received this message because you are subscribed to the Google Groups "Everything List" group.
