Remarkable feat, to put all hands (even students)

What a feat on the part of the Canadian scientist, is known for its renowned qualities popularizer.
But for once, and we will not be fooled by the layout and cover "child", the theory is presented in its entirety, in all its rigor. This is not one of those rough "great public" stories published in spades by gender specialists (specialist publications, no relativity!).
We find in the end the few mathematical development enabling any schoolboy sit rigorously the concepts previously acquired by intuition (you can even demonstrate the transformation Lorenz in 2 times 3 movements!).

We find in the development of the author annoyance with abstract presentations and historically false relativity found in 90% of university textbooks (and often criticized by E. Klein in particular).

Do not hesitate to recommend the book to all the L3 students studying RR, if they have at their disposal a transformation Lorenz placed on the Michelson-Morley !! You hiding to read, but read it!
I just regret that the author did not explicitly included the idea of ​​constant speed in space-time that I had found in the course of the athenaeum of Luxembourg (high school level), and that was not bad too ( when one is stationary in space, we move in time - time passes - and when moving in space, it inevitably moves slower in time so that our speed in space-time is always constant) ...

Finally, a small mix of all this will address the mathematical study of the thing with one (or more) steps ahead. Therefore recommend the Hladik, accessible at L1-L2, to have a rigorous course and free of embarrassing slag all other courses that merely copy itself over each other from one generation to another without understanding real.
