We are special in the sense that we can know our place in the cosmos. We can know our place in space. We are at least one of the cosmos's ways of knowing itself. That fills me with reverence and joy. Another insight I really want people to consider is this: everyone has gotten this far. Everyone you meet has made it this far. Nobody is superior to anyone else from an evolutionary standpoint.

Science is the best idea humans have ever had. The more people who embrace that idea, the better.

When we sit down to draw or paint the sun's rays, we generally use yellow because in the morning and the evening with the blue light scattered away so strongly you're left with a little bit of red and it comes out yellowish.

There are two ways to be rich: to have more or need less. It's estimated that we squander about 30 percent of our energy leaving the lights on, the refrigerator door open, and so on. Then there is the enormous amount of food that we expend huge amounts of energy to raise and then throw away.

If NASA is to reach beyond the Moon and someday reach Mars, it must be relieved of the burden of launching people and cargo to low earth orbit. To do that, we must invest more in commercial spaceflight.

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.

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