We have a way of discussing the world, when we talk of it at various hierarchies, or levels. Now I do not mean to be very precise, dividing the world into definite levels, but I will indicate, by describing a set of ideas, what I mean by hierarchies of ideas. For example, at one end we have the fundamental laws of physics. Then we invent other terms for concepts which are approximate, which have, we believe, their ultimate explanation in terms of the fundamental laws. For instance, “heat”. Heat is supposed to be jiggling, and the word for a hot …

It starts out all right, with the good, and love, and Christ, and so on, and it builds itself up until it’s afraid of an enemy. And then it forgets its original idea. It turns itself inside out and becomes absolutely contrary to the beginning. I believe that the people who start some of these things, especially the volunteer ladies of Altadena, have a good heart and understand a little bit that it’s good, the Constitution, and so on, but they are lead astray in the system of the thing.

Regarding the design of a nuclear fission trigger that ignites a fusion bomb. Levitation gave the imploding shell time to acquire momentum before it hit the core. Nuclear-weapons designer Theodore B. Taylor explained the principle to the writer John McPhee once without naming it: “The way to get more energy into the middle was to hit the core harder. When you hammer a nail, what do you do? Do you put the hammer on the nail and push?” The solid Fat Man core had been pushed; levitation hammered. And because it increased efficiency, levitation also made it possible to design …

While I was at the [Ethics of Equality in Education] conference, I stayed at the Jewish Theological Seminary, where young rabbis- I think they were Orthodox- were studying. Since I have a Jewish background, I knew some of the things they told me about the Talmud, but I had never seen the Talmud. It was very interesting. It’s got big pages, and in a little square in the corner of the page is the original Talmud, and in a sort of L-shaped margin, all around this square, are commentaries written by different people. The Talmud has evolved, and everything has …
