    What is the relationship between depth and pressure in water?

    Slightly tangential, but I have to ask what the circumstances of this injury were

    Courses Courses for freshman year in physics

    As much as I love your schedule, the calc 3 and 4 and diff equations courses would probably be more relevant to any physics courses you take than things like abstract algebra, group theory, analysis and differential geometry. Honestly, those probably won't be helpful for any courses you take...

    Referring to professors in a paper

    This is sort of off-topic, but I couldn't find a better forum to ask in. I'm writing a paper for my internship, and I need to refer to one of my professors for purposes of background information. I want to do this in a professional manner. Should I say Professor Xxxx Xxxxxxx, Ph.D.? Should...

    Referring to professors in papers

    I just noticed that I accidentally clicked on the math forum instead of the physics one. Feel free to move this.

    Visualizing the hyperspheres (only the hyperspheres, no tesseracts etc. please)

    The trouble with higher dimensions is that we can't visualize them. Ultimately, you have to let the math do the seeing for you.

    Mysterious Lunar Ring in the French Alps

    It might be a 22 degree halo. These rely on ice particles in the air, so it makes sense that you would see it in the alps. http://en.wikipedia.org/wiki/22_degree_halo"

    Source for relativistic electrodynamics

    Relativity is built into Maxwell's equations. As long as you want classical rather than quantum electrodynamics, any modern text on Maxwell's equations should do.

    Question about refractive index and momentum

    Well in some sense mass is just the extent to which a particle doesn't behave like those that travel at the speed of light. The fact that photons are massless does not prevent them from exerting a gravitational influence, for instance. If photons didn't have a gravitational influence, momentum...

    Van de Graaf Accelerator question

    Gettysburg College, and that's why I'm working on it. I want to go into theoretical particle physics. Possibly QG, but the standard model seems like a good stepping stone.

    Van de Graaf Accelerator question

    Buying time on another would defeat the entire purpose of my work. I'm developing this accelerator as a laboratory tool for students to use. That's actually where this one came from. It was found in a barn at Duke University by one of our professors in the late 90s. We got it for free but...

    Van de Graaf Accelerator question

    Yeah well as an intern I can't exactly go procure a more powerful accelerator. We've been doing successful RBS. Waiting on an x-ray detector feedthrough to try PIXE.

    Question about refractive index and momentum

    That's not entirely correct. The photons actually do slow down. Their frequency remains the same however, and is still useful for calculating momentum. If you want to use wavelength to calculate momentum, you have to use vacuum wavelength.

    Lhc particles harmful to humans?

    The beam indeed does circulate in a vacuum. This means you would need some sort of breathing apparatus. Also, the entire beamline is cooled to something like 70 K (~-200 C), so you would rapidly freeze to death if you were in contact with anything. Additionally, your body heat might...
