"OUTSTANDING ACADEMIC TITLE" (2000) "Clear and engaging style" "extensive discussion of misconceptions about relativity indicates the author's long experience in teaching this material." "Highly recommended." --- ALA's  "CHOICE" Magazine, published by Association of College and Research Libraries, Sept 2000

"...serves as an excellent textbook or supplement for any serious student of special relativity" "The first half to two-thirds of the book should be accessible to anyone with reasonable competence in first-year algebra and sufficient motivation: I could easily see even bright ninth and tenth graders benefitting from it." "...aims to correct this 'understanding gap.' " --- "The Physics Teacher" published by American Association of Physics Teachers   Feb 2001

"marvelously well written. The style is fast-moving and breezy." "the book does indeed live up to its billing, as ‘serious but not ponderous.'" "the gradual increase in difficulty is also very well done." --- from an independent review for University of Chicago Press

"...This isn't a casual 'physics for art majors' treatment. It's 'physics for the intelligent, driven nonphysicist.' " --- "Sky and Telescope," September 2001

"...We were so pleased with your Relativity book last year for our senior summer reading, that this year's seniors will also be reading it. This is unusual for us, as we normally change each year. "... Thanks for a great resource." --- Jacklyn Bonneau, teacher, Massachusetts Academy of Math and Science

"...son vivant ouvrage ... ce livre, effectivement 'sérioux mais non pesant' ne s'en tient pas aux seules prèmices et quoique destiné à un public non-spécialiste, il va audelà de la simple vulgarisation." "Tout au long de l'ouvrage, la terminologie reste précise, l'argumentation abordable, concise." "...l'un des mérites de cet ouvrage technique d'initiation est sans doute de montrer sans complications excessives comment s'appliquent les règles de calcul propres à la relativité spéciale, domaine où notre intuition de l'espace et du temps s'avère plutôt un obstacle qu'une aide." --- Jean-François Courtot, "Pulsar 743" - Mars/Avril 2001

"for the first time I have found a book on relativity that is both rigorous and readable" "just as a question arises in the reader's mind about something [the book] said, it addresses it on the next page." ---Donald Wulfinghoff, author of award-winning "Energy Efficiency Manual"

"A first class job of laying the groundwork, which, of course, is the hard part." --- David Halliday, co-author of "Fundamentals of Physics"

"At last you have cleared up for me the 'lookback time' vs relativistic effects problem -- it has nagged at me for years." --- Keith Burrows, physics teacher, Australia
