The Coast to Coast Radio Show guys are super-interesting; could it have something to to with all of them being Gemini People? They keep me up night after night with their Innovative, Interesting stuff you'd NEVER see on the 6 o'clock News. I've learned a tremendous amount of new things, like about the 400 mph flying cars they're now working on. UFO's are believable to me because I've seen two different types, myself. I also know why that woolly mammouth had the tropical leaves in its mouth and stomach, just before it froze to death in Siberia, 30,000 years ago and that the Earth IS going to flip over on its side again soon and WHY.. Ever notice that the Pyramids are all at the same latitude and generally look like tire wheel-balance weights? Why do you suppose that is? Or that Stone Henge was a grease rack for flying saucer wheel repairs. (It's the right size and shape. Just add hay bales on top to avoid scratching.) I wouldn't miss Coast to Coast for anything.

I've been taking Rozerem for several weeks now, and it doesn't put me to sleep. The same thing happened with Lunesta. I never changed either dose 2mg for Lunesta, 8 mg for Rozerem. My sleep never really improved, could something else be wrong?

You are pulling your sister on a sled to the top of a 24.0 m high, frictionless hill with a 10.0° incline. Your sister and the sled have a total mass of 50.0 kg. You pull the sled, starting from rest, with a constant force of 127 N at an angle of 45.0° to the hill. If you pull from the bottom to the top, what will the speed of the sled be when you reach the top?

A woman is reported to have fallen 137 ft from a building, landing on a metal ventilator box, which she crushed to a depth of 30 in. She suffered only minor injuries.

(a) Neglecting air resistance, calculate the speed of the woman just before she collided with the ventilator box.
in ft/s
(b) Calculate her average acceleration while in contact with the box.
in ft/s2
(c) Calculate the time it took to crush the box.
in seconds

It is TERRIFYING to me, that in the double slit experiment, electrons behave differently when we LOOK at them or when they are observed. They actually behave as waves even when 1 electron is fired at a time through the double slits. BUT, if you introduce a detector to see which slit the particle went through, it KNOWS it is being watched and decides to stop acting like a wave and it hits the screen and shows up as a particle. I think this is perhaps the most amazing thing ever discovered in science (at least one of them). What are the implications of this? Neils Bohr said "anyone who is not SHOCKED by quantum mechanics does not understand it." I am shocked, but what am I to think of this? What do you think?

I'm building a small remote control submarine, and I want to know if a motor can get partially wet. If not, how can I waterproof it?
Basically, what I need to do is have the motor in a pipe and the motor be mounted at a 15 degree angle to the rest of the submarine. I will only have the propellor in the water. I don't think I can not completely waterproof the holes, and I'll keep the motors separate from batteries. If they aren't waterproof, can you tell me how I can make them waterproof?
