We recently had someone submit a question entitled "Is love a
purely chemical reaction?" It's important to understand science because
it applies to every part of our lives. No matter what you are studying
in college, you will have questions that can be answered only with
science. For example, if love were truly a purely chemical reaction,
philosphers would have much less to talk about. But how could they know
if it is or not if they don't know at least a little bit of science?
Athletes also have to understand science in order to know how to
best play their game. Try searching our answers sections for the word
'tennis' or 'basketball'. You might be surprised how much science there
On to question number 2... Much though I'm sure you'd like me to,
I'm not going to write your paper for you. I would suggest that you go
and run a search for 'Eratosthenes'. I guarantee that you will get plenty of useful information.
For your last question, there are a lot of different definitions of
'rock' and 'mineral'. For example, one definition says that a rock is a
chunk of stuff made up of minerals, and that a mineral is a pure
crystal of an element. Another definition says that a mineral is just a
rock that contains only inorganic molecules. Without knowing what
definitions your teacher is using, I can't really answer your question.
