Summary

Summary

How Euler Did It is a collection of 40 monthly columns that appeared on MAA Online between November 2003 and February 2007 about the mathematical and scientific work of the great 18th-century Swiss mathematician Leonhard Euler. Inside we find interesting stories about Euler's work in geometry and his solution to Cramer's paradox and its role in the early days of linear algebra. We see Euler's first proof of Fermat's little theorem for which he used mathematical induction, as well as his discovery of over a hundred pairs of amicable numbers, and his work on odd perfect numbers, about which little is known even today. Professor Sandifer based his columns on Euler's own words in the original language in which they were written. In this way, the author was able to uncover many details that are not found in other sources.

Choice Review

Sandifer (Western Connecticut State Univ.) offers a collection of articles by the same name that appeared on the Mathematical Association of America's MAA Online over a period of four years starting in 2003. These articles are a look at the work and influence of Leonhard Euler, one of the greatest 18th-century mathematicians. Each article reviews, comments on, and explains the mathematics that this Swiss mathematician made famous. The articles are interesting to read on several levels: mathematically, historically, and for plain fun. The order in which one reads the articles is for the most part not an issue, as they were originally meant to be read individually. Sandifer based his articles on Euler's own words, in the original language in which they were written, thus he was able to uncover many details not found in other sources. The collection ends with a humorous, but factual, description of Euler's role in the discovery of America. Summing Up: Recommended. General readers; lower-division undergraduates through faculty. M.
