Hungarian-born Erdős believed that the meaning of life was to prove and conjecture. His work in the United States and all over the world has earned him the titles of the century's leading number theorist and the most prolific mathematician who ever lived. Erdős's important work has proved pivotal to the development of computer science, and his unique personality makes him an unforgettable character in the world of mathematics. Incapable of the smallest of household tasks and having no permanent home or job, he was sustained by the generosity of colleagues and by his own belief in the beauty of numbers. Witty and filled with the sort of mathematical puzzles that intrigued Erdős and continue to fascinate mathematicians today, My Brain Is Open is the story of this strange genius and a journey in his footsteps through the world of mathematics, where universal truths await discovery like hidden treasures and where brilliant proofs are poetry.

    The Times called it elegant, discursive, and littered with quotes and allusions from Aquinas via Gershwin to Woolf and The Philadelphia Inquirer praised it as absolutely scintillating. In this delightful new book, Robert Kaplan, writing together with his wife Ellen Kaplan, once again takes us on a witty, literate, and accessible tour of the world of mathematics. Where The Nothing That Is looked at math through the lens of zero, The Art of the Infinite takes infinity, in its countless guises, as a touchstone for understanding mathematical thinking. Tracing a path from Pythagoras, whose great Theorem led inexorably to a discovery that his followers tried in vain to keep secret (the existence of irrational numbers); through Descartes and Leibniz; to the brilliant, haunted Georg Cantor, who proved that infinity can come in different sizes, the Kaplans show how the attempt to grasp the ungraspable embodies the essence of mathematics. The Kaplans guide us through the Republic of Numbers, where we meet both its upstanding citizens and more shadowy dwellers; and we travel across the plane of geometry into the unlikely realm where parallel lines meet. Along the way, deft character studies of great mathematicians (and equally colorful lesser ones) illustrate the opposed yet intertwined modes of mathematical thinking: the intutionist notion that we discover mathematical truth as it exists, and the formalist belief that math is true because we invent consistent rules for it. Less than All, wrote William Blake, cannot satisfy Man. The Art of the Infinite shows us some of the ways that Man has grappled with All, and reveals mathematics as one of the most exhilarating expressions of the human imagination.

    Traditional mathematics teaching is largely about solving exactly stated problems exactly, yet life often hands us partly defined problems needing only moderately accurate solutions. This engaging book is an antidote to the rigor mortis brought on by too much mathematical rigor, teaching us how to guess answers without needing a proof or an exact calculation.In Street-Fighting Mathematics, Sanjoy Mahajan builds, sharpens, and demonstrates tools for educated guessing and down-and-dirty, opportunistic problem solving across diverse fields of knowledge--from mathematics to management. Mahajan describes six tools: dimensional analysis, easy cases, lumping, picture proofs, successive approximation, and reasoning by analogy. Illustrating each tool with numerous examples, he carefully separates the tool--the general principle--from the particular application so that the reader can most easily grasp the tool itself to use on problems of particular interest. Street-Fighting Mathematics grew out of a short course taught by the author at MIT for students ranging from first-year undergraduates to graduate students ready for careers in physics, mathematics, management, electrical engineering, computer science, and biology. They benefited from an approach that avoided rigor and taught them how to use mathematics to solve real problems.Street-Fighting Mathematics will appear in print and online under a Creative Commons Noncommercial Share Alike license.

    Men like Andrew Carnegie built empires like Carnegie Steel, and financiers like J.P. Morgan merged and consolidated them. The era also made names like Astor, Cooke, and Vanderbilt instantly recognizable across the globe. Over time, the unfathomable wealth generated by the businesses made the individuals on top incredibly rich, and that in turn led to immense criticism and an infamous epithet used to rail against them: robber barons. Dozens of men were called “robber barons”, but few of them were as notorious as Cornelius Vanderbilt, who also happened to be one of the nation’s first business titans. Vanderbilt was a railroad and shipping magnate at a time that the industry was almost brand new, but he rode his success to become one of the richest and most powerful men in American history. When historians are asked to name the richest man in history, a name that often pops up is that of John D. Rockefeller, who co-founded Standard Oil and turned it into the first real trust in the United States. Rockefeller had been groomed ambitiously by a huckster father nicknamed “Devil Bill”, who was just as willing to cheat his son as an unsuspecting public, and John certainly chased his dreams of living long and large. Rockefeller forged his empire in the first few decades of his life and nearly worked himself to death by the time he was 50, which helped compel him to retire for the last several decades of his life. At one point, Rockefeller’s wealth was worth more than 1.5% of the entire country’s gross domestic product, and by adjusting for inflation, he is arguably the richest man in American history if not world history. When robber barons across America took the reins of vast industries, they needed financing, and many of them turned to the most famous banker of all: John Pierpont Morgan. It was J.P. Morgan who bankrolled the consolidation of behemoth corporations across various industries, including the merging of Edison General Electric and Thomson-Houston Electric Company, which subsequently became General Electric, still known simply as GE across the world today. Similarly, he financed Federal Steel Company and consolidated various other steel businesses to help form the United States Steel Corporation. While critics complained about the outsized influence that these gigantic businesses had, Morgan’s massive wealth also gave him unprecedented power in the financial sector and the ability to deal with politicians. In fact, Morgan played an important part in the Panic of 1907 and the subsequent decision to create the Federal Reserve as a monetary oversight. Ironically, one of America’s most famous robber barons, Andrew Carnegie, epitomized the American Dream, migrating with his poor family to America in the mid-19th century and rising to the top of the business world in his adopted country. A prodigious writer in addition to his keen sense of business, Carnegie was one of the most outspoken champions of capitalism at a time when there was pushback among lower social classes who witnessed the great disparities in wealth; as he once put it, “Upon the sacredness of property civilization itself depends—the right of the laborer to his hundred dollars in the savings bank, and equally the legal right of the millionaire to his millions.

    From the early Greek influences to the Middle Ages and the Renaissance to the end of the 19th century, trace the fascinating foundation of mathematics as it developed through the ages. Aristotle, Galileo, Kepler, Newton: you know the names. Now here's what they really did, and the effect their discoveries had on our culture, all explained in a way the layperson can understand. Begin with the basis of arithmetic (Plato and the introduction of geometry), and discover why the use of Arabic numerals was critical to the development of both commerce and science. The development of calculus made space travel a reality, while the abacus prefigured the computer. The greats examined in depth include Leonardo da Vinci, a brilliant mathematician as well as artist; Pascal, who laid out the theory of probabilities; and Fermat, whose intriguing theory has only recently been solved.

    As exciting as any action/adventure novel, this is actually the story of incredible individuals and engrossing tales behind the most profound, enduring mathematical theorems.Archimedes famously ran naked through the streets shouting, “Eureka, eureka!” after finding a method for measuring the volume of an irregular-shaped object. René Descartes was not only a great French mathematician, philosopher, physicist, and natural scientist; he was also an expert swordsman who traveled with European armies from town to town, dressed in green taffeta and accompanied by a valet. Georg Cantor grappled with mental illness as he explored the highly counterintuitive, bizarre properties of infinite sets and numbers. Emmy Noether struggled to find employment as she laid the mathematical groundwork for modern theoretical physics. And Alexander Grothendieck taught himself mathematics while interned in Nazi concentration camps, only to disappear into the Pyrenees at the zenith of his career.These are just a few stories recounted in this absorbing narrative. In probing the lives of the preeminent mathematicians in history, a Strange Wilderness will leave you entertained and enlightened, with a newfound appreciation of the tenacity, complexity, and brilliance of the mathematical genius.
