As the years have gone by, starting quite early, I realized I tried to formulate a picture of the universe. In a sense, a theory of everything. Whenever I hear something new, I try to fit it into the picture that I have already formed of the universe. If it fits in, well and good, I don’t need to worry about it. But, if it doesn’t fit in, then I ask, “Why doesn’t it fit in with my ideas about how the universe ought to be operating?” I’d better try to find the answer to that. So, then I can ask, “How well is my background of knowledge and experience, such that I have a reasonable chance of finding the answer?” And if it isn’t, then I say, “Well, perhaps someone else will make some progress with that idea, but I better go on with the others.” So, I have lots of ideas. I do a lot of scientific reading, and quite often, every week perhaps, I read about something that someone is reporting that puzzles me. So I have a big pile of questions of this sort that I would like to settle down to work on.
