People get a lot out of being religious. They have strong senses of community and mutual support. So, what's not to love [there]?

I've always loved airplanes and flight. The space program was really important to me as a kid. I still have a photo of Armstrong and Aldrin on the moon in my living room.

The thing about a theory in science is it allows you make predictions. Evolutionary theory allows us to predict what apples will taste good next harvest.

If you look back on all the teachers that you liked, I am sure you will find they were very entertaining.

I often reflect on what an extraordinary time (pun intended) it is to be alive here in the beginning of the twenty-first century. It took life billions of years to get to this point. It took humans thousands of years to piece together a meaningful understanding of our cosmos, our planet and ourselves. Think how fortunate we are to know this much. But think also of all that's yet to be discovered. Here's hoping the deep answers to the deep questions-from the nature of consciousness to the origin of life-will be found in not too much more time.

I try to speak plainly and be sympathetic to the idea of religions where people gather in community. They get a sense of people looking out for each other. My claim is that we have a tendency to look out for each other whether or not there is a religion involved.

In another couple centuries I'm sure that worldview won't even exist. There's no evidence for it.
