Journey through Genius: The Great Theorems of Mathematics Paperback – August 1, 1991
Purchase options and add-ons
Dunham places each theorem within its historical context and explores the very human and often turbulent life of the creator — from Archimedes, the absentminded theoretician whose absorption in his work often precluded eating or bathing, to Gerolamo Cardano, the sixteenth-century mathematician whose accomplishments flourished despite a bizarre array of misadventures, to the paranoid genius of modern times, Georg Cantor. He also provides step-by-step proofs for the theorems, each easily accessible to readers with no more than a knowledge of high school mathematics. A rare combination of the historical, biographical, and mathematical, Journey Through Genius is a fascinating introduction to a neglected field of human creativity.
“It is mathematics presented as a series of works of art; a fascinating lingering over individual examples of ingenuity and insight. It is mathematics by lightning flash.” —Isaac Asimov

Amazing book I love it

- Reviewed in the United States on June 13, 2019In a phrase, this is one of my favorite books on mathematics. I read it first when it was recommended by my Calculus I professor and thought it was great. I read it again when I took a course in the history of mathematics and thought it was brilliant. Now it remains one of my favorites and I return to it regularly for discussion of some remarkable theorems and the great minds who produced them.
One of the first questions anyone might have before reading a book about mathematics is what level of mathematical sophistication is required on the part of the reader. In this case, the reader can feel pretty safe. While these are real and deep mathematical theorems, their proofs only require high-school level mathematics. In the vast majority of cases, the reader familiar with basic algebra and a little bit of geometry will have no trouble following the discussions. One theorem (Newton's approximation of pi) requires a little bit of integral calculus and another (the discussion of some of Euler's sums) requires a smidge of elementary trigonometry. In both cases, the author holds the reader's hand through the discussion so even if you haven't taken a course in trigonometry or calculus, you'll still be able to follow most of the conversation.
In fact, even if you don't really have a lot of algebra and geometry, the bulk of the book will still be accessible to you. The majority of the text is a history of mathematics wherein the author discusses the context and importance of the theorems and some biographical details of their discoverers. While I find the recreations of the proofs themselves to be perhaps the most interesting part, the reader with a general interest (even if that interest is not supported by mathematical skill) will find the book fascinating. For those of us who do have some knowledge of mathematics, though, the recreations of the theorems presented in their historical context provides a rich and inspiring series of vignettes from the history of mathematics.
This brings us to another important point. While this is a book about the history of mathematics. it is not *a* history of mathematics, and the theorems selected are not the only "great" theorems of mathematics, but a cross-section thereof. Many readers of sufficient mathematical background may quibble over the inclusion of some theorems at the expense of others--personally I would like to have seen more from combinatorics--but no one can deny that these theorems are remarkable in their elegance and in their importance in the development of mathematics from the Ancient Greeks to the very end of the nineteenth century.
It might be helpful to know what theorems are actually included in the book. Aside from a handful of lemmas and minor results presented before or after each of the "Great Theorems," the book consists of a single major result per chapter. They are:
*Hippocrates' quadrature of the lune
*Euclid's proof of the Pythagorean Theorem
*Euclid's proof of the infinitude of primes
*Archimedes' determination of a formula for circular area
*Heron's formula for triangular area
*Cardano's solution of the cubic
*Netwon's approximation of pi
*Bernoulli's proof of the divergence of the harmonic series
*Euler's evaluation of the infinite series 1+1/4+1/9+1/16+...
*Euler's refutation of Fermat's conjecture
*Cantor's proof that the interval (0,1) is not countable
*Cantor's theorem that the power set of A has strictly greater cardinality than A
Each of these theorems is surrounded by the historical discussion that makes this book a triumph not merely of teaching a dozen results to students but of actually educating students on the human enterprise of mathematics. It is not only interesting but, I think, important to be reminded of the human side of a field as abstract as mathematics, and Dunham bridges the mathematical and the biographical with remarkable dexterity. It is useful for the student of mathematics to understand that Cantor's work on the transfinite was resisted by the mathematicians of his day just as much as students struggle with it when they're exposed to it in today's lecture halls. It might further be useful to know that, perhaps partly due to his demeanor and perhaps partly due to the attacks on his work, Cantor spent much of his life in mental hospitals--and yet, despite his unhappy life his work has achieved immortality as one of the great developments in mathematical history.
I can't recommend this book highly enough for the mathematician, the math student, or the merely curious. In fact, I recommend reading it twice. First, just read it straight through and enjoy the story of mathematics told through these vignettes. Then read it again with pencil and paper in hand and work through the theorems and proofs with the author as your guide. You'll come away with a much deeper understanding of and appreciation for these great theorems in particular and mathematics in general.
- Reviewed in the United States on November 12, 2024What a fun read. I love mathematics, but I don't remember ever enjoying a math book so much. A combination of math history, biographies, and proofs. And to top it off, well-written and engaging. I was first exposed to Dr. Dunham through The Great Courses. He offers a class there with the same format as this book. This book, though, goes into much more depth. A big thank you to Dr. Dunham.
- Reviewed in the United States on October 23, 2024The book was delivered in pristine condition and the delivery was prompt. The book itself is wonderful. The whole experience was great.
- Reviewed in the United States on January 6, 2012This is a wonderful book. People with a basic grasp of math who are open to the idea that math might be beautiful will be rewarded. But I have a PhD in math and thoroughly enjoyed it, and learned some things along the way. (Because math is taught very ahistorically, Chapter 1 was entirely unfamiliar to me).
These are *not* "*The* Great Theorems of Mathematics," as the subtitle suggests, but they certainly are "Great Theorems of Mathematics." Most "Great Theorems" are too technical to be presented in a book of this sort, but Mr. Dunham has done a wonderful job selecting theorems that can be proved with a minimum of prerequisites. In some ways this is a more challenging task than choosing the "greatest" theorems.
My main reservation is the fact that at times the proofs get more ponderous than necessary, and can wind up obscuring the simplicity and elegance of the mathematics. The most glaring example is the already-noted proof of Fermat's Little Theorem (p. 226-9). The proof is incomplete, and presented in a very obscure way. The key fact, that (a+b)^p = a^p + b^p (mod p) follows easily and beautifully from the binomial theorem, so a complete proof could be given quite straightforwardly. I had the sense that some of the other theorems could have been presented somewhat more cleanly as well.
The story behind Bernoulli's proof of the divergence of the harmonic series is enjoyable, but Bernoulli's proof is complex and unmotivated. Happily Mr. Dunham presents the beautiful proof Nicole Oresme from the 14th century. It is superior to Bernoulli's in every way: shorter, more elegant, and more illuminating, since pursuing his line of thinking makes it clear that the series grows as the log of the number of terms. So it's hard to see why Bernoulli is getting high marks for this particular proof, though he is overall a towering figure in the history of mathematics.
Really, all my complaints are nit-picking. This is a wonderful book.
I do want to defend Mr. Dunham from one of the other reviews: Euclid can prove (in modern language) that the area of a circle divided by the radius squared is a constant, and he can prove that the circumference divided by the diameter is a constant. But Euclid didn't show that these are the *same* constant, and that is why Archimedes result can fairly be seen as "greater" than Euclid's. Not that those theorems of Euclid's were slouches by any means.

I ordered this book which was very influential to me the first time I read a copy from my local library back in 1992; this is one of my favorite books, and I decided to buy a hard cover copy from Amazon. The book came mostly in good condition, freshly printed, just 5 days before it was delivered to my home. I rate the Amazon service with 4 stars because the covers are slightly warped, and there is a stain (fingerprint?) at the bottom edge of the book. This was an unpleasant experience for me, I can't help but feeling a little disappointed and frustrated, but at least now I have my own copy of this great book (don't judge a book by its cover). All pages appear to be properly printed. Ordered on May 13th, 2022 from Amazon website, delivered to my home on June 2nd, 2022; printed in Monee, IL, USA, on May 28th, 2022.

If to her grace, some female errors fall, look into her face and you will forget them all (Alexander Pope). And if mathematics is a science of enigma to you (and of enigmas, which of course it is), read this book and you will start to see, in parts even comprehend its beauty.
