Nobody gets argued all the way into becoming a believer on the sheer basis of logic and reason. That requires a leap of faith.

The word 'living' has so many connotations that I'm almost reluctant to try to define it scientifically because it sounds as if I'm then downgrading all the other significances of that word.

[Locating, from scratch, the gene related to a disease is like] trying to find a burned-out light bulb in a house located somewhere between the East and West coasts without knowing the state, much less the town or street the house is on.

What wakes me up at night is this next generation and what's happening to them. And they're invariably excited about the science that they're doing, but invariably anxious about where there's a future.

There are 15 constants- the gravitational constant, various constants about the strong and weak nuclear force, etc.- that have precise values. If any one of those constants was off by even one part in a million, or in some cases, by one part in a million million, the universe could not have actually come to the point where we see it. Matter would not have been able to coalesce, there would have been no galaxy, stars, planets or people

It's interesting when you read the life of Christ how much of his time he spent healing the sick. There must have been a reason for that - he was modelling for us what it is we are intended to do by following his path.

I took biology in high school and didn't like it at all. It was focused on memorization. ... I didn't appreciate that biology also had principles and logic ... [rather than dealing with a] messy thing called life. It just wasn't organized, and I wanted to stick with the nice pristine sciences of chemistry and physics, where everything made sense. I wish I had learned sooner that biology could be fun as well.
