This may not be answerable. I'm not sure. Or maybe not in the form I am asking. Could you sustain 1 earth gravity of acceleration in an automobile?

A Two Hundred Dubloon Coin is unique in that the outer edge is gold while the inside is silver. Assuming both sides of the coin are identical, and a line tangent to the inner circle is 23 mm from edge to edge of the coin, and excluding the edge of the coin in the calculation, what is the surface area of gold on the coin, in square millimetres? Please round up to the nearest square millimetre.

lets say you are observing humans as just another species of animal on this planet (oh, yeah, we are!). how would you classify humans in terms of their behaviors and effect of such behaviours on the planet?

if something accelerates at an angle, say 3m/s^2 at 30 degrees above horizon, does that mean it accelerate cos(30)3 horizonally and sin(30)3 vertically?

Why does it take longer to open-and-close one eye (wink) then two eyes (blink)?

You would think it would take less time to just close one.

There has been a _continuous_ human presence in space for a number of years now. On what date did that continuous presence start?

Note: I'm NOT asking, "when did people start going into space." I know that was 1959. I'm asking, "when was the last time outer space was completely free of humans?"

I'm hovering at the decision point between completing my MS and going on to the PhD.

I want to know what kinds of jobs I would be looking at with the MS, because I'm not sure I want to go all the way to the doctorate -- I enjoy my work, but I feel that the PhD can be limiting in some instances.. it's not so much about money, but I want to know that if I stay with the MS, I'll actually have job opportunities that don't involve glorified bottle washing!

Can anyone who has been here give any advice?
