People are starting to go on about my weight but I'm not going to change my size because they don't like the way I look.
It is no good getting furious if you get stuck. What I do is keep thinking about the problem but work on something else. Sometimes it is years before I see the way forward. In the case of information loss and black holes, it was 29 years.
Music is harmony, harmony is perfection, perfection is our dream, and our dream is heaven.
