I find the mechanics of the atom are not clear to me. I understand that the Bohr "step" of electrons in orbit is non-applicable anymore, then there is De Broglie's wave theory, this is never built upon. I always find it just mentioned never expanded on, I'm left with basic questions, okay so do...

Homework Statement Hi, for our homework, we have to create a billiard game with c#. What I need help is when the picture box (containing a picture of a ball) reaches one of the pockets, how do I remove it from the form/program? Is there some kind of delete keyword I can use or will I have to...

So we need a new picture and the weather is freezing fog. Hence rime ice time. The bigger waters are still open, the fog is more intense there, the place to go for new rime ice pictures. 100% crop 100% crop Now, which one to enter in the contest?

It is often stated that the transition amplitude between eigenstates of the free-field Hamiltonian H_0 is encoded by the S-matrix, defined by \langle \mathrm{f} | U{_\mathrm{I}} (\infty,-\infty)|\mathrm{i} \rangle. where U_{\mathrm{I}} is the time-evolution operator in the interaction...

So for the Autumn picture contest I chosed an awesome view of the Danube valley. Unfortunately the sun wasn't that bright that day. So the choice was scenery versus light. Scenery won, these were the losers:

I know undergrad QM fairly well. There they use the EM potential to introduce EM fields into the momentum. What should I study to understand the connection between EM fields and actual photon particles?

Bad Picture 3 This theme has always been one of our more popular theme. Find a photo that you took that is really bad. This degree of "badness" can be due to fuzzyness, underexposure, overexposure, etc. Any picture that it technically bad qualifies. NOTE: You cannot use pictures that have...

I understand a wavepacket as a better description of a particle than the classical 'solid object' but is there a similar simple picture for an entangled pair? Is it a double wave packet? Is it two joined wavepackets? Is it one wave packet with two objects in it? Is it actually one complex...

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 not sure why, but I could never really picture & grasp this concept. Say you're drawing the orbitals of an atom, the 1s & 2s orbitals are pretty easy to draw. They are just spheres with a node in between them. Now do these orbitals overlap, or does one start where the node ends? What...

Can X rays be produced by a television picture tube? My attempt It is possible that X-rays can be produced by a television picture tube or a Cathode Ray tube because by altering the CRT X- rays may be produced. I have no idea if that is true but i think so.
