The story of the Harvard mathematics department’s growth into one of the world’s premier centers of mathematical research is of interest not only in its own right but as a microcosm of the development of the larger American mathematical community. A collaboration between a scientific journalist (Nadis) and an eminent Harvard mathematician (Yau) has now brought us a very readable account of this history.

[The authors] treat mathematics of ever-increasing theoretical difficulty with hands that manage deftly…to reveal the spirit, the excitement, and the dynamics of the mathematical endeavor at the cutting edge of research.

Yau and Nadis succeed admirably in making clear how Harvard has long served as a magnet, attracting some of the world’s best mathematicians and thus making it an exciting place to be, a melting pot of mathematical activity.

[An] interesting history of mathematics at Harvard… The book starts from the mid-19th century, when mathematics came into being as an area of study at Harvard University. It reveals a myriad of personalities who have contributed to its prestige as a center of mathematical research. It portrays life at Harvard from around 1825 to times of the great depression and the years following the 2nd World War. More importantly, it provides meaningful insight into all sorts of mathematical topics.

The remarkable result is an account, at a consistently clear, non-specialist level, of a wide swath of modern mathematics.

The development of American mathematics, and American education more generally, cannot be told without an account of Harvard University… Though a department history seems like a parochial exercise, Harvard’s mathematics department’s history is much bigger and well worth the read.

This book tells the tale of how mathematics developed at Harvard—and by extension in the United States—since early days. It is filled with fascinating stories about some of the legendary names of modern mathematics. Both fans of mathematics and readers curious about the history of Harvard will enjoy it.

A History in Sum is a beautiful tribute to a beautiful subject, one that illuminates mathematics through the lens of some of its most remarkable practitioners. The authors’ love of mathematics shines through every chapter, as they use accessible and spirited language to describe a wealth of heady insights and the all-too-human stories of the minds that discovered them. There is perhaps no better book for immersion into the curious and compelling history of mathematical thought.

A triumph! I know of no other book like A History in Sum. Nadis and Yau offer a delightfully lucid introduction to the dazzling and heroic ideas of twentieth-century mathematics—and the colorful personalities and stories behind them.

Nadis and Yau are very successful at bringing some of the major figures in American mathematics to life. A History in Sum is a genuine and valuable addition to the world of mathematical biography.

A History in Sum contains a wealth of good stories, stories that go to the heart of the development of mathematics in this country. The authors succeed in humanizing and enlivening what might otherwise be a dry treatment of the subject.

The book is written in a leisurely style, the scope is remarkably broad, and the topics covered are explained astonishingly well. Once I started the book, I simply couldn’t put it down and I was ecstatic to easily understand important mathematics far from my own research interests.
