Following closely behind is y, or gamma, a constant that arises in many mathematical areas yet maintains a profound sense of mystery. In a tantalizing blend of history and mathematics, Julian Havil takes the reader on a journey through logarithms and the harmonic series, the two defining elements of gamma, toward the first account of gamma's place in mathematics. Introduced by the Swiss mathematician Leonhard Euler (1707-1783), who figures prominently in this book, gamma is defined as the limit of the sum of 1 + 1/2 + 1/3 + . . . Up to 1/n, minus the natural logarithm of n--the numerical value being 0.5772156. . . . But unlike its more celebrated colleagues π and e, the exact nature of gamma remains a mystery--we don't even know if gamma can be expressed as a fraction. Among the numerous topics that arise during this historical odyssey into fundamental mathematical ideas are the Prime Number Theorem and the most important open problem in mathematics today--the Riemann Hypothesis (though no proof of either is offered!). Sure to be popular with not only students and instructors but all math aficionados, Gamma takes us through countries, centuries, lives, and works, unfolding along the way the stories of some remarkable mathematics from some remarkable mathematicians.-- "Notices of the American Mathematical Society"

    For mathematicians, physicists, engineers, and everyone else with an interest in mathematics' cutting edge, The Millennium Problems is the definitive account of a subject that will have a very long shelf life.

    

    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.

    Dana Mackenzie starts from the opposite premise: He celebrates equations. No history of art would be complete without pictures. Why, then, should a history of mathematics -- the universal language of science -- keep the masterpieces of the subject hidden behind a veil?"The Universe in Zero Words" tells the history of twenty-four great and beautiful equations that have shaped mathematics, science, and society -- from the elementary (1+1 = 2) to the sophisticated (the Black-Scholes formula for financial derivatives), and from the famous (E = mc^2) to the arcane (Hamilton's quaternion equations). Mackenzie, who has been called a "popular-science ace" by Booklist magazine, lucidly explains what each equation means, who discovered it (and how), and how it has affected our lives.(From the jacket copy.)Note: The Princeton University Press version (black cover) is for sale in the English-speaking world outside Australia.

Martinez and even selected as required reading for a college course on baseball history, "The Book of Baseball Literacy: 3rd Edition" puts over a century and a half of legends and lore, right in your mitt. It will settle arguments and provoke them, answer questions and ask them. It’s a must for veteran baseball fans—and a perfect way to get up to speed on baseball history for newcomers.

    Carter's unpopularity helped Republicans win seats in the House and gain control over the Senate for the first time in over 20 years. The Reagan Era had begun, ushering in a generation of conservative power. Democrats blamed Carter for this catastrophe and spent the next decade pretending he had never existed. Republicans cheered his demise and trotted out his name to scare voters for years to come. Carter and his wife Rosalynn returned to their farm in the small town of Plains, Georgia. They were humiliated, widely unpopular, and even in financial debt. 35 years later, Carter has become the most celebrated post-president in American history. He has won the Nobel Peace Prize, written bestselling books, and become lauded across the world for his efforts on behalf of peace and social justice. Ex-presidents now adopt the Carter model of leveraging their eminent status to benefit humanity. By pursuing diplomatic missions, leading missions to end poverty and working to eradicate disease around the world, Carter has transformed the idea of what a president can accomplish after leaving the White House.This is the story of how Jimmy Carter lost the biggest political prize on earth--but managed to win back something much greater.

    He discovered the Conway groups in mathematical symmetry, and invented the aptly named surreal numbers, as well as the cult classic Game of Life--more than a cool fad, Life demonstrates how simplicity generates complexity and the game provides an analogy for all mathematics and the entire universe. Moving to Princeton in 1987, as a mathemagician he deployed cards, ropes, dice, coat hangers, and even the odd Slinky as props to extend his winning imagination and share his mathy obsessions with signature contagion. He is a jet-setting ambassador-at-large for the beauties of all things mathematical.Genius At Play is an intimate investigation into the mind of an endearing genius, laying bare Conway's personal and professional idiosyncrasies. The intimacy comes courtesy of the man himself. He generously granted Roberts full access, though not without the occasional grudge and grumble: "Oh hell," he'd say. "You're not going to put that in the book. Are you?!?

    The view 16-year-old Thomas Osborne first had of Muskoka was at night, trudging alone with his even younger brother along unmarked primitive roads to find their luckless father who, in 1875, had decided to make a new start for his beleaguered family on some "free land" in the bush east of the pioneer village of Huntsville, Ontario. The miracle is that Thomas lived to tell the tale.For the next five years Thomas endured starvation, falling through the ice and freezing, accidents with axes and boats, and narrow escapes from wolves and bears. Many years later, after returning to the United States, Osborne wrote down all his adventures in a graphic memoir that has become, in the words of author and journalist Roy MacGregor, "an undiscovered Canadian classic."Reluctant Pioneer provides a brooding sense of adventure and un- sentimental realism to deliver a powerful account of pioneer life where tragedies arrive as naturally as rain and where humour resides in irony.
