I think science and religion should be separate.

The Ph.D. system was designed for a job in academics. And it works really well if you really want to be an academic, and the system actually works quite well. So for people who have the gift and like to go spend their lives as scholars, it's fine. But the trouble is that it's become a kind of a meal ticket - you can't get a job if you don't have a Ph.D.

Lucky individuals in each generation find technology appropriate to their needs.

Successful technologies often begin as hobbies. Jacques Cousteau invented scuba diving because he enjoyed exploring caves. The Wright brothers invented flying as a relief from the monotony of their normal business of selling and repairing bicycles.

Boiled down to one sentence, my message is the unboundedness of life and the unboundedness of human destiny.

That's what I learned from World War II. Things are always more complicated than most people believe.

We should try to introduce our children to science today as a rebellion against poverty and ugliness and militarism and economic injustice.
