If I know the: Frequency Effective Radiated Power Height Above Average Terrain Radiation Center Above Mean Sea Level Radiation Center Above Ground Level of a radio signal / tower, is there a way to determine the rough range of the radio signal?

The Hill sphere of a celestial object is the area in which it is the dominating force in the area. I was wondering how the formula was determined. If the mass of the smaller body is m, and it orbits a heavier body of mass M with a semi-major axis a and an eccentricity of e, then the radius...

The last step before getting my degree in Mathematics is a senior thesis that I need to write. Ideally I could combine my interest in astronomy/astrophysics with a math focus and have a thesis I'd actually be interested in writing. I'm just coming up short as far as ideas go. Does anyone have...

I'm interested in going to grad school for astrophysics. I've loved everything about the subject for many years now. At first I thought it was just a hobby interest, but I think it may have crossed the line and become a career interest. The only problem with this is that I'm in my senior year in...

You have a weight on one end of a piece of string and you run that piece of string through a tube, and then on the other end you attach a cork. You hold on to the tube and try and keep the cork spinning at a constant radius, such that the weight stays dangling at the same height. As you increase...

Ya, but that isn't done by projection. It's done by having a lot of small cameras on one side of you that transmit the images they see to a lot of tiny screens on your other side.

I'm pretty sure it's mainly that the spinning causes lower pressure. Because, if you throw a frisbee upside down, it hits the ground very quickly.

If a black hole has an infinite density, then one would think that anything would float inside of it. And since it's infinitely dense, the object(s) being pulled in would have an infinite buoyancy, causing it to be shot back out of the black hole at a seemingly infinite speed. So why don't...

My physics teacher gave everyone in his class this handout just before we broke for Christmas break. I know this is a little late in coming, but I thought you all might find it interesting. 1. Flying Reindeer No known species of reindeer can fly. BUT there are 300,000 species of living...

Perpetual motion has been deemed "impossible", at least in the world we live in. Why aren't the perfectly elastic collisions between gas particles considered perpetual motion?

Or, the more likely thing, he posted it as a subtle clue to anyone who doesn't know the answer.

I don't know... trying to double major in 2 challenging engineering fields will be very difficult.

That's the other major I was thinking about, but which would be better for what I want to do? (Stated in post #1)

Alright, I've always had a fascination with computers, as I'm sure many people out there have. My question is, what should I major in while in college so that when I graduate, I have the ability to do anything from designing video games, to being an IT guy for a major company? At the moment...

But you have to remember, that's only the way we, humans, think about it. That doesn't necessarily make it the way the universe itself works.
