Our population and our use of the finite resources of planet Earth are growing exponentially, along with our technical ability to change the environment for good or ill.

A picture is worth a thousand words...and uses up a thousand times the memory.

I don't think the human race will survive the next thousand years, unless we spread into space.

Science can lift people out of poverty and cure disease. That, in turn, will reduce civil unrest.

The whole history of science has been the gradual realization that events do not happen in an arbitrary manner, but that they reflect a certain underlying order, which may or may not be divinely inspired.

Just like a computer, we must remember things in the order in which entropy increases. This makes the second law of thermodynamics almost trivial. Disorder increases with time because we measure time in the direction in which disorder increases. You can't have a safer bet than that!

I am just a child who has never grown up. I still keep asking these 'how' and 'why' questions. Occasionally, I find an answer.
