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

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.

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.

Success equals goals; all else is commentary.

Most people struggle with life balance simply because they haven’t paid the price to decide what is really important to them.

Don’t walk through life just playing football. Don’t walk through life just being an athlete. Athletics will fade. Character and integrity and really making an impact on someone’s life, that’s the ultimate vision, that’s the ultimate goal – bottom line.

Goals reflect your choice of destination.

Take a minute: look at your goals, look at your performance, see if your behavior matches your goals.

Picture yourself in your minds eye as having already achieved this goal. See yourself doing the things you’ll be doing when you’ve reached your goal.

Connect the dots between individual roles and the goals of the organization. When people see that connection, they get a lot of energy out of work. They feel the importance, dignity, and meaning in their job.

I fight for the man next to me. It don’t matter about me, what matters about me is sacrificing for you; for the ultimate goal which is us.
