There are 3 heavens as taught in the Bible:

1-Heaven-->where the birds fly.

2-Heaven-->space and galaxies

3-Heaven-->God's home in the spirit world, which cannot be explained by old or modern science.

What is heaven to you?

Water temperature plays a major role in determining the strength of a hurricane. Will the passage of Hurricane Dean reduce the water temperature such that following storms may be less powerful ? How much time is required for the water to return to its pre-Dean temperature ?

I've lost my calculator operation manual for the TI-92 Plus calculator. Does anyone know of a good URL for this calcuator's functions and operations? I can get the device to do all of the basic arithmetic operations and thngs like LOG and Ln functions. However, with Trig. operations and transendental functions, all I get is the equation organized and presented in symbolic form. Even when I make the equation equal to some variable, it doesn't give a "result" answer. I feel like there is one more step in the operation that I need to do but I have no idea what that step is.

If anyone has experience with this calculator, maybe you can tell me what it is that I'm doing wrong. That would be a really big help.

Thanks in advance.

Ok, so the bomb i'm talking about is like vinegar and baking soda in a bottle. It's really cool and loud. But I was wondering what similar things you can make with household products. Anyone know of some homemade bombs?

We know there is on the order of 10^21 stars in our universe. Many people say "since there are so many stars, it's naive to say that Earth is the only 'special' one". For starters, it is true that we know very little on this matter. How can people assume that there MUST be life elsewhere when we don't know the parameters for having life in the first place. Given that there are so many stars, it's very viable to say that most of those 10^21 stars can't house life at all. We don't know what major influences have to come into play. Given that we know so little of either path, why do people base their beliefs when neither side--pro or anti--has any idea what pieces all have to amalgamate to create life, or for that matter, intelligent life?
