A product in solid form usually has molecules more closely bound, thus making the product more dense and thus heavier. However, solid water (ice) is lighter than water and floats.
Why?

I would like to find code in any language (matlab, Perl, C, ...) for fitting a mixture of Beta distributions to data. I would also like to find a write-up of the associated mathematics (not general EM, but EM for this particular problem - mixture of Beta distributions.). I would like both, but I will be happy to get either.

Why are they trying to change Pluto's category as a planet?? Why can't they stop discriminating against it for its size?

You won't find God mentioned in a biology textbook.
I always hear people talking about the origin of life and it seems they only take one side and not the other.
I am a biology student but my religion comes first, but i also believe that it is possible that God used evolution as one of the tools to create life.
ie: Evolution could not have taken place if God did not want it to.

Is it so crazy to believe that evolution and creationism can go hand in hand and are infact inseperable?
