Joseph built the pyramids in order to store grain. Now, all the archeologists think that they were made for the pharaoh's graves. But, you know, it would have to be something awfully big, when you stop and think about it - and I don't think it would just disappear over the course of time - to store that much grain.

Reading activates and exercises the mind. Reading forces the mind to discriminate. From the beginning, readers have to recognize letters printed on the page, make them into words, the words into sentences, and the sentences into concepts. Reading pushes us to use our imagination and makes us more creatively inclined.

I would love to see music reinstated as an essential part of schooling. The culture that it brings; the knowledge that it brings. Just learning how to read music requires metrics, and I think that helps you with mathematics. A lot of scientists and doctors have a musical background - it's very interesting.

Economics is not brain surgery.

I'm not even sure I like surgery, but I like what it does, I like the effects. I like to be able to give people longevity and quality of life, and I also think it's good for people to use the special gifts and talents that they have. And when I was in medical school, when I began to analyze the gifts and talents that I had, I realized that surgery would probably be a very good fit for me.

In general I was a good kid. It usually took a lot to make me mad. But once I reached the boiling point, I lost all rational control. Totally without thinking, when my anger was aroused, I grabbed the nearest brick, rock, or stick to bash someone. It was as if I had no conscious will in the matter.

I said Ted Cruz has been lying because if you say something that isn't true, and you say it over and over again, and you know that it's not true, there's no other word for it.
