Carl Sagan Atom Quotations

There are more potential combinations of DNA [physical forms] than there are atoms in the universe.

If we are merely matter intricately assembled, is this really demeaning? If there's nothing here but atoms, does that make us less or does that make matter more?

There are as many atoms in one molecule of DNA as there are stars in a typical galaxy.

Atoms are mainly empty space. Matter is composed chiefly of nothing.

My fundamental premise about the brain is that its workings - what we sometimes call "mind" - are a consequence of its anatomy and physiology, and nothing more.
