“The Big Bang banged, and for some reason we’re here. And that’s astonishing. And that we can understand that, that’s the most astonishing.”

I feel that I’ve often pointed out that there are countless aspects of life and nature that scientists and scientific thinkers cannot explain.

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.

Science is the best thing humans beings have ever come up with. And if it isn’t, science will fix it.

Humor is everywhere in that there’s irony in just about anything a human does.

But as the cerebellum degrades with age, so does the quality of memories. The memories are there, but they’re not as good.

The world’s going to change climatically. We just want to control the change. We want to have a high quality of life for billions of people as we pass through this era.

The US Navy has several people on every ship that can navigate by the stars. They don’t fool with that.

I stand by my assertions that although you can know what happens to any individual species that you modify, you cannot be certain what will happen to the ecosystem.

NASA is an engine of innovation and inspiration as well as the world’s premier space exploration agency, and we are well served by politicians working to keep it that way, instead of turning it into a mere jobs program, or worse, cutting its budget.

Without an end to the burning of fossil fuels, coal especially, most of us will live shorter lives. I’m hopeful, but very, very concerned.

Tax dollars intended for science education must not be used to teach creationism as any sort of real explanation of nature, because any observation or process of inference about our origin and the nature of the universe disproves creationism in every respect.

My father was a very good Boy Scout. He was very skilled with knots, and he showed me how to tie a bow tie.

If you just take a single human and put him or her in the forest he or she might not do very well without some sort of education which he got or she got from some tribe.

When we see the shadow on our images, are we seeing the time 11 minutes ago on Mars? Or are we seeing the time on Mars as observed from Earth now? It’s like time travel problems in science fiction. When is now; when was then?

Winter lingered so long in the lap of Spring that it occasioned a great deal of talk.

Our goal in science is to discover universal laws of nature. That pursuit fills me with wonder.
