We are bits of stellar matter that got cold by accident, bits of a star gone wrong.

Science is one thing, wisdom is another. Science is an edged tool, with which men play like children, and cut their own fingers.

The understanding between a non-technical writer and his reader is that he shall talk more or less like a human being and not like an Act of Parliament.
