This book worked for me in a couple of ways. First, it did a better job than any other text I've read to convey the sense of historical development in physics from the 1890s to the 1980s (mostly through the 1930s)... the sense of what burning questions people had, what unexpected insights changed the trajectory of the discipline, etc.
Second, it managed to go a layer deeper into the various topics in the latter half of the book than anything I have read before and give some punchy, satisfying answers to questions like why the strong force behaves as it does. The solid state physics part has some intriguing comments like the conduction electrons of a metal behaving as a degenerate Fermi gas, including a fairly substantive description of what that means.
Interestingly, I thought the presentation of the Schrodinger equation itself was perhaps the least compelling part of the book, at least compared to other texts I've read (most recently McQuarrie's Quantum Chemistry and Eisberg and Resnick's Quantum Physics).
As an overview text to give me a broader sense of 20th century physics I thought this book succeeded well. Now I have my appetite whetted to go deeper and more of a sense how to get there.
