Not his best work, but interesting nonetheless
on 23 November 2004
This is basically transcripts of a series of lectures given by Feynman. As such they are informal in style, but also relaxed on things such as sentence structure an punctuation. I'm not just being picky because this led to me having trouble reading some of the passages, they're not impenetrable, just not to his usual high standard.
The content however is good. I have read a few of his books and I wouldn't rate this amongst his best work. Usually he puts a new slant on ideas, presenting them in a way which gives fresh insights, but that isn't so evident here. He did introduce a couple of new concepts to me, like the equivalence of the symmetries and conservation laws, and how orbits can be described by conservation. These were entirely new though, so it wasn't like the new understanding of general relativity I gained from 'Six Not-so-Easy Pieces'. The final chapter on 'Seeking New Laws' fails to strike the right note for me, falling short of it's aims to explain where innovation comes from.
This is a book which doesn't deal directly with the laws of physics, there's plenty of those around already, some from the same author. It deals instead with the general structure of these laws, and how it is possible to have these laws in the first place. As such it is an interesting read, and should be considered if you have tired of books on relativity and quantum mechanics.
