Dyson's remarks on his personal experience as a student at Cambridge with Ludwig Wittgenstein are interesting. Wittgenstein was a brilliant but troubled person.
Dyson thinks "the multiverse is philosophy and not science." He writes: "Science is about facts that can be tested and mysteries that can be explored, and I see no way of testing hypotheses of the multiverse." I laughed when I read "the multiverse has its place in philosophy and in literature." It was a Scandinavian-Finnish laugh, which is indiscernible to anyone nearby.
