And all I knew about drugs was what I read in magazines like Time and Life. I learned that marijuana was a dangerous addictive drug and that I should stay away from it.

I can say exactly what I feel about any issue, and I'm going to do that.

I'm not driven by being understood.

We were fortunate to have the Russians as our childhood enemies. We practiced hiding under our desks in case they had the temerity to drop a nuclear weapon.

Science grows like a weed every year.

You can't ask your pharmacist to stock larger quantities of potassium nitrate because you want to make a bigger rocket.

Scientists are doing an awful lot of damage to the world in the name of helping it. I don't mind attacking my own fraternity because I am ashamed of it.
