I thought that I understood these issues well, having been a researcher in the area myself until 1987, but I have to report that they filled embarrassingly large gaps in my knowledge, particularly in relation to experiments, including in subjects that I used to teach to undergraduates.
I would recommend this book to anyone, but most of all to those who call themselves practitioners in the subject, to remind them of how, if at all, what they do fits in to the bigger picture, and also to remind them, to quote Murray Gell Mann (who was probably quoting someone else at the time), that "the best instrument that a theoretician has is his waste paper basket". As the mathematical tangents that theoreticians have gone off on in the last twenty years get ever more bizarre and disconnected from reality, I fully expect this to be full to overflowing soon.
