When I learned that our ancestors were tree shrews, I became suspicious of squirrels. The other day I saw a "herd" of them grazing on my lawn. They've come down from the trees, I tell you!!! Soon enough they'll be making stone tools and building fires. How long, do you think, before they usurp us? Should I build some sort of shelter or bunker? Should I stock up on duct tape?

Is it me or the fact that we landed on the moon a stupid thing?
If you think about it how many people have made it to the moon or space alive and back? I think we never made it to the moon of the fact that the most recent missions have all failed but the one time they tryed they got it right so has tecnology changed for the worst?

In a hypothetical universe, an oil-drop experiment gave the following measurements of charges on oil drops: -3.21×10-19 C, -4.28×10-19 C, -5.35×10-19 C, and -7.49×10-19 C. Assume that the smallest difference in charge equals the unit of negative charge in this universe.

I know that a lot of creationist use the argument when arguing for the existant of God that the chance of a universe coming into exsistance and that planet would be able to support life, without some kind of creator, is rediculously small. Not like 1 in a million small. Like infintesimly small. Now this thread isnt about God so I dont want to here people belief systems. My question is if the chances that a place like earth coming into existance are so small than arent the chances that say ten other planets able to support intelligent life somewhere in our vast universe like a million time less likely. My point is every is convinced that aliens are out there, but when you think about does there really have to be intelligent life out there?

Two samples of different compounds of sulfur and oxygen have the following compositions. You can show that these compounds follow the law of multiple proportions by calculating the ratio of oxygen in the two compounds for a fixed amount of sulfur.

I know this question has probably been asked a thousand times already and its probably old news... but does anyone else feel outraged (don't know if thats the right word to use!) that pluto is no longer a planet. I can't see how after years and years of saying its a planet and teaching everyone that its a planet and documenting it as a planet someone can just turn arouns and say no it's not a planet anymore!!!
