I'll admit that the discovery of evolution is humbling, but it is also empowering. It transforms our relationship to the life around us. Instead of being outsiders watching the natural world go by, we are insiders. We are part of the process; we are the exquisite result of billions of years of natural research and development.

We are just a speck, on a speck, orbiting a speck, in the corner of a speck, in the middle of nowhere.

You and I are made of stardust. We are the stuff of exploded stars. We are therefore, at least 1 way that the Universe knows itself. That, to me, is astonishing.

To leave the world better than you found it, sometimes you have to pick up other people's trash.

Our goal in science is to discover universal laws of nature. If one's faith requires one to abandon or ignore natural laws, well, that person is going to have trouble reconciling religion and science. Otherwise, there is no any conflict.

As you may know, I am a mechanical engineer.

There really is no such thing as race. We all came from Africa. We are all of the same stardust. We are all going to live and die on the same planet, a Pale Blue Dot in the vastness of space. We have to work together.
