  • Impossible?by Julian Havil

    Princeton University Press 2011; US$ 19.95

    In Nonplussed! , popular-math writer Julian Havil delighted readers with a mind-boggling array of implausible yet true mathematical paradoxes. Now Havil is back with Impossible? , another marvelous medley of the utterly confusing, profound, and unbelievable--and all of it mathematically irrefutable. Whenever Forty-second Street in New York is... more...

  • Nonplussed!by Julian Havil

    Princeton University Press 2010; US$ 16.95

    Math--the application of reasonable logic to reasonable assumptions--usually produces reasonable results. But sometimes math generates astonishing paradoxes--conclusions that seem completely unreasonable or just plain impossible but that are nevertheless demonstrably true. Did you know that a losing sports team can become a winning one by adding worse... more...

  • John Napierby Julian Havil

    Princeton University Press 2014; US$ 35.00

    John Napier (1550?1617) is celebrated today as the man who invented logarithms?an enormous intellectual achievement that would soon lead to the development of their mechanical equivalent in the slide rule: the two would serve humanity as the principal means of calculation until the mid-1970s. Yet, despite Napier?s pioneering efforts, his life and... more...

  • The Irrationalsby Julian Havil

    Princeton University Press 2012; US$ 18.95

    The ancient Greeks discovered them, but it wasn?t until the nineteenth century that irrational numbers were properly understood and rigorously defined, and even today not all their mysteries have been revealed. In The Irrationals , the first popular and comprehensive book on the subject, Julian Havil tells the story of irrational numbers and the... more...

  • Gammaby Julian Havil; Freeman Dyson

    Princeton University Press 2010; US$ 19.95

    Among the myriad of constants that appear in mathematics, p , e , and i are the most familiar. Following closely behind is g , 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... more...

  • Gammaby Julian Havil; M. Stern; Manfred Stern

    Springer-Verlag Berlin and Heidelberg GmbH & Co. KG 2007; US$ 9.95

    Jeder kennt die Kreiszahl p = 3,14159, viele kennen auch e = 2,71828, die Basis der natrlichen Logarithmen, und die imaginre Einheit i. Und dann? Die viertwichtigste" Konstante ist die Eulersche Zahl g = 0,5772156, benannt nach dem genialen Leonhard Euler (1707-1783). p und e sind transzendent, aber bis heute ist unbekannt, ob g eine rationale... more...
