Hello,
I'm a third year engineering physics student, and my team and I are trying to model how the rotation (V(r)) of a galaxy is affected by the possible existence of the dark matter halo. Here are my questions:
Regarding the dark matter halo:
The integral of the mass density function...
Is it possible to build a physical tesseract? I am thinking of building one, but I'm not sure what to do with the joints.

Hello!
Well I am in second year Engineering Physics and we're building a robot this summer. We have four students in my team including myself. We're to build a robot that follows a loop of black tape on a track, and race with other robots.
I have a few questions:
1. We decided to use...
I think I can relate to your obsession with that girl. I'm slightly older than you, and I have in fact, been into your situation before (without the psychological issues). I was very obsessed with a girl and I thought she was perfect. Now, 3 years later, I realize it was silly and meaningless as...
Homework Statement
The fireball of a uranium fission bomb consists of a sphere of radius = 15m and temperature 300,000K shortly after detonation. Assuming that the expansion is adiabatic and that the fireball remains spherical, estimate the radius of the ball when the temperature is 3000K...
