New Books in Mathematics

Today we’ll be discussing Lance Fortnow‘s bookThe Golden Ticket:P, NP, and the Search for the Impossible (Princeton University Press, 2013).The book focuses on the challenges associated with solving problems requiring significant computation, such as “What is the largest group of Facebook users, all of whom know each other?”If it is shown that all computational problems can be solved relatively easily (this is known as showing that P=NP), then such problems as finding a cure for cancer and other diseases would be much more easily solved.

You may well have seen “Numb3rs,” a TV show in which mathematicians help solve crimes. It’s fiction. But, as Leila Schneps and Coralie Colmez show in their eye-opening new book Math on Trial: How Numbers Get Used and Abused in the Court Room (Basic Books, 2013) math does play a role in criminal prosecution. Alas, it’s often bad math and, as such, often leads to bad outcomes: people get off who shouldn’t and others get convicted who shouldn’t. Schneps and Colmez show how math has been misused in ten interesting (and disturbing) cases. In some instances the errors are trivial; in others rather complex. But they all add up (excuse the pun) to injustice. Listen in and find out how and why. Learn more about your ad choices.

Challenging conventional modes of understanding China and the circulation of knowledge within the history of science, Catherine Jami‘s new book looks closely at the imperial science of the reign of the Kangxi Emperor (r. 1662-1722). It focuses on the history of mathematics in this context, but situates the story of mathematics and Kangxi within a larger framework that extends from the late Ming through the years after Kangxi’s reign, and treating much more than mathematics in the course of the analysis. The Emperor’s New Mathematics: Western Learning and Imperial Authority During the Kangxi Reign (1662-1722) (Oxford University Press, 2012) takes us from the beginning of Western learning in China in the late Ming dynasty through the commissioning by Kangxi of a massive compendium that was the largest mathematical work ever printed in imperial China. Along the way, Jami’s work surveys the changing pedagogy of imperial mathematics in late imperial China, the crucial role that materiality and instruments played in the mathematics of this period, the many languages of sciences at the court, and the ways that Kangxi alternately used Jesuit mathematics to undergird his authority over Chinese scholar-officials, and sidelined them in the service of championing the mathematical knowledge of Chinese scholars and Bannermen. It is a rich and powerful account that rewards a wide range of readers. Enjoy! Learn more about your ad choices.

Roger Hart‘s The Chinese Roots of Linear Algebra (Johns Hopkins University Press, 2011) is the first book-length study of linear algebra in imperial China, and is based on an astounding combination of erudition and expertise in both Chinese history and the practice and history of linear algebra. Alternating among an interdisciplinary array of materials and ideas that range from the Nine Chapters on the Mathematical Arts to modern matrix theory, Hart argues for the importance of visualization to the solution of linear algebra problems in China in the years before Leibniz. In the course of a detailed and exhaustive account of fangcheng practice, Hart explores issues of primary importance to the history of science broadly writ, including the relationship and distinction between popular and elite knowledge, the challenges of inferring and extracting historical practices from the textual record, and the challenges of translating scientific terminology across the languages and cultures of the past and present. Hart’s book is a unique and standout contribution to the history of science in what have been called “non-Western” cultures, and our conversation touched on both the specifics of his study and the broader historiographical issues that his work speaks to.
