I was hoping someone could point me in the direction of the best way to calculate the rest energy of a proton. I am a complete noob with the standard model, so please be gentle. My goal is to compare a calculation of the energy which accounts for the quark structure of the proton versus E=mc^2...

I am attempting to compute the integral of a function that is mostly flat relative to a few localized peaks. These peaks are the bulk of the contribution to the integral. I decided to try the VEGAS algorithm to do this. I am running into some difficulty, so I am reaching out to YOU...

This thread got me searching others about virtual particles. I've found the user 'tom.stoer' to have the most lucid take on the subject. It seems that virtual photons only show up if you approach the problem using perturbation theory. If you use the approach in Quantum Mechanics of Gauge...

Thanks guys. I'll continue reading about virtual photons. Any more questions related to this will probably be posted in the Quantum forum.

Maybe I'm being sloppy with my terminology. I'm quite certain that it is accurate to say that the quanta of electromagnetic radiation are photons. And electromagnetic radiation is the electromagnetic field produced by accelerating charges. So it seems then that the quanta of the...

What comprises the electrostatic field? Electromagnetic radiation is made of photons, but what about the electrostatic field? Two static charges exert forces on one another, through their E-fields, presumably through photon exchanges. I am having trouble forming an idea of what an...

Hi guys, I'm a physicist and would appreciate some direction in helping me understand the dynamics (or chemistry) of graphite in a bath of liquid metal. Eventually the bath is cooled into a solid ingot. There are several different metals which are used (Cu, Fe, Al as well as many alloys). Any...

This was posted years ago, but incase someone else is searching through this (as I was), you can use Matlab quite easily to calculate this. You can use the equations found here: http://www.netdenizen.com/emagnet/offaxis/iloopoffaxis.htm They are simple equations which you just plug in the...

If you are interested, a retired professor in the Georgia Tech physics department, Professor David Finkelstein, is attempting to work out a quantum theory which includes quantized space-time. He would characterize the current quantum theories as semi-classical. :)
