After an introductory chapter 1, which quickly previews much of the later material, French systematically analyzes the many observations and contradictions (the Michelson-Morley experiment just one of them), astronomical and laboratory, about the behavior of light that fitted neither an ether-wave model or a particle model. We are thus lead to a deeper appreciation for Einstein's insight and genius in his creation of the special theory of relativity; it was much more than just an extension of the Lorentz-transformations.
French is a master at his subject, and his systematic elucidation will reward the reader with a deep understanding. His problems are very well designed, and he provides answers which is always very helpful in learning.
If you have some time, and would like also to gain historical perspective about what it was like to struggle for a consistent theory in a mass of contradictory observations from the world view of Newtonian mechanics, I highly recommend this book.
