“I am writing to tell you how impressed I was when I just yesterday picked up a copy of your book at a local bookstore here in Princeton. I browsed the preface, then flipped to the back cover and saw your photograph.  I also saw old-German gothic letters along the wall next to you, turned the book in the light to better read them, then almost dropped the book in complete surprise!

‘Raffiniert ‘ist der HerrGott’!!  What an excellent pun -- no wonder you are mischieviously smiling!  I am sure Einstein would NOT be amused!—George McGhee, Professor of Paleobiology, Department of Earth & Planetary Sciences, Rutgers University

“I just read your Einstein’s Mistakes, and am quite taken with your style. It is different, unique and very engaging.  Very simply, I love it…”—Don Richards, Lexington

I enjoyed reading your book on Einstein. It is a great story told exceptionally well. A thought that came to my mind is that whether there exist overlooked ‘mistakes’ in more recent physics. For example, could the use of quantum entropy (von Neumann)…be a problem given that this measure does not
satisfy intuitive ideas of information.—Subhash Kak, Professor and Head of Computer Science Department, Oklahoma State University, Stillwater

I am a 66 year old real estate lawyer, a scientific layperson with a totally inadequate background in mathematics. I just finished reading Einstein’s Mistakes and enjoyed it very much. I especially enjoyed the way you managed to weave stories about some of the great scientists of all ages, Galileo and Newton, for example, into the narrative. The thing that I will take away from the book is the nature of Einstein's genius, so many of his discoveries were predicated on just thinking about things. I think in words, so it is hard for me to imagine his visual way of thinking. I was also struck by the fact, as you emphasize, that so much of the important work in physics was done by young men and women. I would have thought that years of experience would lead to new discoveries, but you seem to indicate that experience seems to lead to ossification of the thought process. The picture of Einstein’s statue near the end of the book brings that home. I understand why the sculptor chose to put that leonine head on what appears to be the body of a young person.—Doug Borchert

And I, little ol' me, can read Hans' book and understand it!!! I am amazed that I can do that! Thank you Hans, for making it comprehensible to little grey haired retired first grade teachers!!!—Georgia Hedrick, Reno
