American students vary in educational achievement, but white students in general typically have better test scores and grades than black students. Why is this the case, and what can school leaders do about it? In The Color of Mind, Derrick Darby and John L. Rury answer these pressing questions and show that we cannot make further progress in closing the achievement gap until we understand its racist origins. Telling the story of what they call the Color of Mind—the idea that there are racial differences in intelligence, character, and behavior—they show how philosophers, such as David Hume and Immanuel Kant, and American statesman Thomas Jefferson, contributed to the construction of this pernicious idea, how it influenced the nature of schooling and student achievement, and how voices of dissent such as Frederick Douglass, Frances Ellen Watkins Harper, and W. E. B. Du Bois debunked the Color of Mind and worked to undo its adverse impacts. Rejecting the view that racial differences in educational achievement are a product of innate or cultural differences, Darby and Rury uncover the historical interplay between ideas about race and American schooling, to show clearly that the racial achievement gap has been socially and institutionally constructed. School leaders striving to bring justice and dignity to American schools today must work to root out the systemic manifestations of these ideas within schools, while still doing what they can to mitigate the negative effects of poverty, segregation, inequality, and other external factors that adversely affect student achievement. While we cannot expect schools alone to solve these vexing social problems, we must demand that they address the dignitary injustices associated with how we track, discipline, and deal with special education that reinforce long-standing racist ideas. That is the only way to expel the Color of Mind from schools, close the racial achievement gap, and afford all children the dignity they deserve.

This elegant little book discusses a famous problem that helped to define the field now known as graph theory: what is the minimum number of colors required to print a map such that no two adjoining countries have the same color, no matter how convoluted their boundaries are. Many famous mathematicians have worked on the problem, but the proof eluded formulation until the 1970s, when it was finally cracked with a brute-force approach using a computer. The Four-Color Theorem begins by discussing the history of the problem up to the new approach given in the 1990s (by Neil Robertson, Daniel Sanders, Paul Seymour, and Robin Thomas). The book then goes into the mathematics, with a detailed discussion of how to convert the originally topological problem into a combinatorial one that is both elementary enough that anyone with a basic knowledge of geometry can follow it and also rigorous enough that a mathematician can read it with satisfaction. The authors discuss the mathematics and point to the philosophical debate that ensued when the proof was announced: just what is a mathematical proof, if it takes a computer to provide one - and is such a thing a proof at all?

On October 23, 1852, Professor Augustus De Morgan wrote a letter to a colleague, unaware that he was launching one of the most famous mathematical conundrums in history--one that would confound thousands of puzzlers for more than a century. This is the amazing story of how the "map problem" was solved. The problem posed in the letter came from a former student: What is the least possible number of colors needed to fill in any map (real or invented) so that neighboring counties are always colored differently? This deceptively simple question was of minimal interest to cartographers, who saw little need to limit how many colors they used. But the problem set off a frenzy among professional mathematicians and amateur problem solvers, among them Lewis Carroll, an astronomer, a botanist, an obsessive golfer, the Bishop of London, a man who set his watch only once a year, a California traffic cop, and a bridegroom who spent his honeymoon coloring maps. In their pursuit of the solution, mathematicians painted maps on doughnuts and horseshoes and played with patterned soccer balls and the great rhombicuboctahedron. It would be more than one hundred years (and countless colored maps) later before the result was finally established. Even then, difficult questions remained, and the intricate solution--which involved no fewer than 1,200 hours of computer time--was greeted with as much dismay as enthusiasm. Providing a clear and elegant explanation of the problem and the proof, Robin Wilson tells how a seemingly innocuous question baffled great minds and stimulated exciting mathematics with far-flung applications. This is the entertaining story of those who failed to prove, and those who ultimately did prove, that four colors do indeed suffice to color any map. This new edition features many color illustrations. It also includes a new foreword by Ian Stewart on the importance of the map problem and how it was solved.

The traditional debate among philosophers of mathematics is whether there is an external mathematical reality, something out there to be discovered, or whether mathematics is the product of the human mind. This provocative book, now available in a revised and expanded paperback edition, goes beyond foundationalist questions to offer what has been called a "postmodern" assessment of the philosophy of mathematics--one that addresses issues of theoretical importance in terms of mathematical experience. By bringing together essays of leading philosophers, mathematicians, logicians, and computer scientists, Thomas Tymoczko reveals an evolving effort to account for the nature of mathematics in relation to other human activities. These accounts include such topics as the history of mathematics as a field of study, predictions about how computers will influence the future organization of mathematics, and what processes a proof undergoes before it reaches publishable form. This expanded edition now contains essays by Penelope Maddy, Michael D. Resnik, and William P. Thurston that address the nature of mathematical proofs. The editor has provided a new afterword and a supplemental bibliography of recent work.
