This is probably Freeman Dyson's best book, although "Infinite in All Directions" comes close. If you've ever seen Dyson speak, he comes across as rather shy and humble. On the written page, however, he is quite bold.His essays range from personal to speculative to profound. But my favorite essays are the ones where he writes very simply about meeting and then working with Robert Oppenheimer. Those essays alone make this book a must read.Out of print? I'm glad I have my copy.
