I'd like to know what humans would look like if they'd been living on the moon for several generations. Exactly how tall would they be? What other changes would their bodies undergo after time? How fast would they run? How high would they jump? Would their skin change at all? Would their voices change?

Many regions on earth have very different climates today compared to prehistoric times. How can some areas have been much warmer than they are today? Did the earth's axis change and thereby change the relationship of the areas on earth to the sun?

I think that gravity is caused by a mass retarding the rate of time near it and that we experience this retardation of time effect as gravity.
Can anyone tell me a good reason why my thought on this could not be true?

No its not homework, I'm trying to understsand the calculus-based derivation of Pi. By "Pythagoras'" theorm, a circle centred on the origin represents this relationship: y = the function above. By taking strips of the circle from from x = -R to x = +R, the area may be composed. By reducing them towards zero width whilst multiplying towards infinity in number, the area may become accurate. Newtons integration makes the calulation exact. The integrated funtion = pi times R squared, we are told. Can anyone help me to understand how this works please?

We were out looking at what appear to be bullfrog tadpoles. I saw one and I reached out to catch it. When I first picked it up, I thought it was dead and that something had pulled the intestines out to snack on it. Then I put it back in the water, and it slowly began swimming, so I picked it up again to investigate. It was mostly yellow, not the nice green with speckles like all the others. It also had light blue blotches all over it and it looked like a half-deflated balloon. On its chin and its backside there were earthworm-looking things hanging off, about five or six inches long. They looked like leeches, but that doesn't explain the odd coloring and such. It swam very slowly when I put it back on the water, and a few fish began nipping it, hoping for a meal. Any ideas???

I'm programming a small computer game and have run up on the following math problem:

Two objects exist on a two dimensional space. One is a moving target, the other is a stationary shooter, firing at the target. Assume that I know all of the following:

The exact location of the shooter and the target at any given point in time.
The distance between the shooter and the target at any given time.
The velocity and direction of motion of the target.
The velocity of the projectile. (constant velocity)
All conditions are ideal: no friction, no changes in velocities or directions, no wind resistance, etc.

How can I determine what direction the shooter should fire in to hit the target at any given time?

I've been racking my brain for a couple of days, and can't figure this one out. Any help is greatly appreciated.
