“Religion is a completely different thing from the claim that the Earth is six thousand years old. That’s just crazy.”

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?

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

The strange thing about grinding that might surprise many people is that you can grind things and shape them using materials that are generally somewhat softer than the thing you’re grinding and shaping.

The most serious problem facing humankind is climate change. All of these people breathing and burning our atmosphere has led to an extraordinarily dangerous situation.

It fills me with joy to know that we can pursue these answers. It is an astonishing thing that we are — you and I are one of the ways the universe knows itself.

Unlike science, creationism cannot predict anything, and it cannot provide satisfactory answers about the past.

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

A few years back, when my style was “punk grandma”, I picked up an amazing pair of sandals – orthopaedic ones, with really thick soles. I’ve given them away to a friend now, because these days my look is more “1980s substitute teacher gone wild.”

My 80s were the best years of my life!

I’ve said for quite a long time I’d like him to have a different haircut. I quite like my hair being short. You know, we’ve been away two years, let’s f*** around with his outfit, let’s f*** around with his haircut, let’s do something different.

I didn’t need to take any fight for the last 10 years. But I’ve always fought the best and I’ve always wanted to prove myself to the best.

Abstraction in photography is ridiculous, and is only an imitation of painting. We stopped imitating painters a hundred years ago, so to imitate them in this day and age is laughable.
