Does the full moon affect certain people across the globe? I've heard that it affects animals, but humans are essentially animals. I've also heard that it does make some people feel "weird" or "different". What is your opinion?

you cant always rely on a test light because a taste light always works as long as there is voltage but if there is to much resistance in the curcuit it will not show.

On my way home from work, and the sky is clear, traveling east, there is this little light in the sky at about "ten o'clock", that caught my eye.....all the stars were out, but this one IS different!!!!...I am not nuts, but you can see colors...I stopped at the intersection to get a really good look at it...(I live in a rural area, no traffic)....and really really looked at it to see if I was seeing what I was seeing.....it is brighter sort of than the stars, lower than the stars, and the "colors" look red and blue... and it isn't a plane, it doesn't move, but the "colors" seem to sort of "move".....I live very close to Ft.Campbell, about 40 min away, so I guess it could be a military thing....but it is in the same spot for almost 4 weeks now....I showed my boss it, and he said it may be a planet......anyone have any sound and not smart alec input???????

If we write
a^(2) + b^(2) = c^(2)
&
c^(2) + d^(2) = e^(2)
where "a" is an odd prime then either "c" will be prime or "e" will be prime other wise d/b will become prime but one of the case for prime will occur.
can anybody provide a counterexample of this statement.

Does anyone know what the actual field is, or if there is a field for any of aforementioned types of projectiles.

I want to go in to engineering, and im especially interested in the above fields. I also am considering trying to enter in to the engineer corps, and would love to work with sorts of artilary engineering. If anyone could help, that'd be incredibly kind.

why is the freezer compartment of a refrigerator typically on top and the non freezer at bottom? wont the heat from the engine go up to the top, essentially causing more electricity to be consumed to maintain the freezing temperature? isnt it a silly idea, seeing that would cause consumers more money?
