I heard that you could find out what latitude you're at if you measure the distance between the horizon and the pole star. So, I'm at the North Pole and therefore I would heave to measure between the north horizon and Polaris.

Now, how do I do that?

when you go into space,
and you head for the moon,
why doesn't the earth just fly away from you.
I believe it moves at 30 km/s. right?
and your not in an orbit?
so why doesn't it just fly away?

Isn't about time we let certain animal species to disappear naturally? I think it's dumb to have a small fish that no one ever knew about stop the construction of a dam that will help mankind. How about that woodpecker that no one is even sure existed any longer but stopped some major project from going thru?
