It provides a simple, thorough survey of elementary topics, starting with set theory and advancing to metric and topological spaces, connectedness, and compactness. 1975 edition.

    The work is predicated on the idea that studying mathematics can generate the same enthusiasm as playing a team sport - without necessarily being competitive.

    On that first day we sold twenty-four bottles, and now we sell over 2 million a week, so we've grown since then. This book is about the stuff we've learned since selling those first few smoothies. About having ideas and making drinks, about running a business and getting started, about nature and fruit, about company life and working with friends, about the stuff we've got right and the stuff we got wrong, and about squirrels . . . and camping . . . and doing the right thing. We thought we'd write it all down in a book so we don't forget any of it, and to maybe help other people too. We started innocent from scratch, so we've learnt a lot of things by getting stuff wrong. Some other lessons have come from listening carefully to people clever than us. And some stuff we just got lucky on. But all of it, the good the bad and the useful, is in here. Plus, perhaps our mums will finally believe us when we tell them we haven't rung home for a while because we've been a bit busy these past few years.

    At last, his path is destined for one last stop: the Baseball Hall of Fame in Cooperstown.Long before he cemented his status as one of the finest players of his generation, Martinez honed his batting skills by hitting rocks in his backyard and swinging for hours at individual raindrops during storms. Loyal and strong-willed from a young age, he made the difficult decision at only 11 to remain behind with his grandparents while his family relocated to New York, attending school and then working multiple jobs until a chance Mariners try-out at age 20 changed everything.In this illuminating, highly personal autobiography, Martinez shares these stories and more with candor, characteristic humility, and surprising wit. Highlights include the memorable 1995 and 2001 seasons, experiences playing with stars like Randy Johnson, Ken Griffey Jr., and Alex Rodriguez, and life after retirement as a family man, social advocate, and Mariners hitting coach. Martinez even offers practical insight into the mental side of baseball and his training regimen, detailing how he taught himself to see the ball better than so many before and after him.Interwoven with Martinez’s own words throughout are those of his teammates, coaches, and contemporaries, contributing a distinctive oral history element to this saga of a remarkable career.

    In How Not to Be Wrong, Jordan Ellenberg shows us how terribly limiting this view is: Math isn’t confined to abstract incidents that never occur in real life, but rather touches everything we do—the whole world is shot through with it.Math allows us to see the hidden structures underneath the messy and chaotic surface of our world. It’s a science of not being wrong, hammered out by centuries of hard work and argument. Armed with the tools of mathematics, we can see through to the true meaning of information we take for granted: How early should you get to the airport? What does “public opinion” really represent? Why do tall parents have shorter children? Who really won Florida in 2000? And how likely are you, really, to develop cancer?How Not to Be Wrong presents the surprising revelations behind all of these questions and many more, using the mathematician’s method of analyzing life and exposing the hard-won insights of the academic community to the layman—minus the jargon. Ellenberg chases mathematical threads through a vast range of time and space, from the everyday to the cosmic, encountering, among other things, baseball, Reaganomics, daring lottery schemes, Voltaire, the replicability crisis in psychology, Italian Renaissance painting, artificial languages, the development of non-Euclidean geometry, the coming obesity apocalypse, Antonin Scalia’s views on crime and punishment, the psychology of slime molds, what Facebook can and can’t figure out about you, and the existence of God.Ellenberg pulls from history as well as from the latest theoretical developments to provide those not trained in math with the knowledge they need. Math, as Ellenberg says, is “an atomic-powered prosthesis that you attach to your common sense, vastly multiplying its reach and strength.” With the tools of mathematics in hand, you can understand the world in a deeper, more meaningful way. How Not to Be Wrong will show you how.

    Louis are all intimately connected with the mysterious number e. In this informal and engaging history, Eli Maor portrays the curious characters and the elegant mathematics that lie behind the number. Designed for a reader with only a modest mathematical background, this biography brings out the central importance of e to mathematics and illuminates a golden era in the age of science.
