Special relativity - a first encounter
As well as deriving the equations of special relativity, Guilini shows how they relate to the rest of physics, for example how Maxwell's equations for electromagnetism become invariant under changes of frame. There is also a chapter showing the derivation of that most famous of equations E=mc2. The final chapter includes the current status of several experimental tests of relativity.
Although the book is subtitled '100 years since Einstein' and has come out at the same time as many other books about him, it is different in that it isn't meant to be biographical - its subject is special relativity rather than Einstein.
