As a revelation from God, they have stood the test of many ages; and as such maintained their ground against every species of enemy, and every mode of attack. Truth is mighty, and must prevail.

Molecules A and B meet, marry, and beget the species. This takes place in one-millionth of a billionth of a second. This is a fundamental process in nature, and the world was looking for a way to be able to see the process. But many brilliant people said it couldn't be done.

There are certain books in the world which every searcher for truth must know: the Bible, the Critique of Pure Reason, the Origin of Species, and Karl Marx's Capital.

When I am at a dinner table, I love to ask everybody, 'How long do you think our species might last?' I've read that the average age of a species, of any species, is about two million years. Is it possible we can have an average life span as a species? And do you picture us two million years more or a million and a half years, or 5,000?

In science, we take large numbers of disparate facts and reduce them to see patterns. We use the patterns to reduce the amount of information. It's the reason we name species and genera and families in biology. It's also the reason we have names for certain types of geological features and so on in other fields.
