Science is the business of generating testable hypotheses.

Kids didn't have huge backpacks when I was their age. We didn't have backpacks at all. Now it seemed all the kids had them. You saw little second-graders bent over like sherpas, dragging themselves through the school doors under the weight of their packs. Some of the kids had their packs on rollers, hauling them like luggage at the airport. I didn't understand any of this. The world was becoming digital; everything was smaller and lighter. But kids at school lugged more weight than ever.

Sometimes I look around my living room, and the most real thing in the room is the television. It's bright and vivid, and the rest of my life looks drab. So I turn the damn thing off. That does it every time. Get my life back.

I am certain there is too much certainty in the world.

And that's how things are. A day is like a whole life. You start out doing one thing, but end up doing something else, plan to run an errand, but never get there. . . . And at the end of your life, your whole existence has the same haphazard quality, too. Your whole life has the same shape as a single day.

Science is nothing more than a method of inquiry. The method says an assertion is valid - and will be universally accepted - only if it can be reproduced by others, and thereby independently verified. The impersonal rigor of the method has produced enormously powerful results for 400 years. The scientific method is utterly apolitical. A truth in science is verifiable whether you are black or white, male or female, old or young. It’s verifiable whether you know the experimenter, or whether you don’t.

Nobody believes a weather prediction twelve hours ahead. Now we're being asked to believe a prediction that goes out 100 years into the future? And make financial investments based on that prediction? Has everybody lost their minds?
