I first read and owned this book in the late 80s whilst studying for a physics degree. In the intervening years I lent my copy to someone who subsequently failed to return it. It has been missed, so much so that I recently bought a used copy of it to cure my longing - sad, I know! It is because I have recently re-acquired it that I am writing this review to tell anyone who cares that this really is a great book.
Now I also have a copy of another MIT Introductory Physics book by A.P. French, namely Newtonian Mechanics which I have to say is not such a great book as it is overly long and verbose. So I can only conclude that the Special Relativity book is just that, a bit special.
Despite the fact that the price has soared since I bought it I can still recommend this book as it is fairly short, clear, concise and readable ( well, as readable as any textbook can realistically be - I nearly wrote, relativistically ).
It was and still is to me the best introductory text book on Special Relativity available.
