Excuse me my lack of expertise, but it is very curious. Recently, I have https://www.physicsforums.com/showthread.php?t=54055", which I qualify 'absolutely amaizing' when I read it. It almost satisfies my curiosity on Laplace because I can almost understand it, except the shift operator. The...

Let's say I have a vector x in \mathcal{R}^3. Let's also suppose that any vector x undergoes the transformation x' = kx (where k is a positive real). Obviously, normalizing the vector will give us a quantity which is invariant to uniform scaling. In fact, \frac{\mathbf{x'}}{|\mathbf{x'}|} =...

A fundamental quantity that we calculate with QM is \langle \Phi|\Psi\rangle-- the probability amplitude for observing a system to be in state |\Phi\rangle given that it is in state |\Psi\rangle. In the Schrodinger picture the states are time-dependent and we can ask, "What is the probability...

I'm working on a 3d physics simulator, and I'm trying to build a nice, easy-to-use camera into it. Currently, the camera allows you to specify inputs that modify (among other things such as zoom) its pitch, yaw, roll, strafe, movement, and elevation. The way it currently works is this: The...
