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.
Learn to count with the #1 New York Times bestselling artist of The Day the Crayons Quit and his hilarious cast of Hueys! "Is none a number?" you might ask. I'm glad you did. The answer is Yes! For example, how many lumps of cheese do you see next to you? The answer, depending on where you are, is likely "none." Counting with the reader all the way up to ten, the Hueys explain numbers as only they can. Such as: The number 4 is the number of tantrums thrown by Dave every day. 7 is the number of oranges balanced on things. And 9 is the number of seagulls who attacked Frank's French fries. Together they make quite a spectacle. But when you take away all of these fun illustrations in the book? You're left with none! This funny and accessible counting book from #1 New York Times bestseller Oliver Jeffers (The Day the Crayons Quit; This Moose Belongs to Me) gives the Hueys one more reason to be every young child's best friends. Praise for NONE THE NUMBER "Delightfully droll and enlightening . . . . The illustrations, 'made with pencils and a bit of color' on large white pages, are deceptively simple and ridiculously funny."--School Library Journal

Today complex numbers have such widespread practical use--from electrical engineering to aeronautics--that few people would expect the story behind their derivation to be filled with adventure and enigma. In An Imaginary Tale, Paul Nahin tells the 2000-year-old history of one of mathematics' most elusive numbers, the square root of minus one, also known as i. He recreates the baffling mathematical problems that conjured it up, and the colorful characters who tried to solve them. In 1878, when two brothers stole a mathematical papyrus from the ancient Egyptian burial site in the Valley of Kings, they led scholars to the earliest known occurrence of the square root of a negative number. The papyrus offered a specific numerical example of how to calculate the volume of a truncated square pyramid, which implied the need for i. In the first century, the mathematician-engineer Heron of Alexandria encountered I in a separate project, but fudged the arithmetic; medieval mathematicians stumbled upon the concept while grappling with the meaning of negative numbers, but dismissed their square roots as nonsense. By the time of Descartes, a theoretical use for these elusive square roots--now called "imaginary numbers"--was suspected, but efforts to solve them led to intense, bitter debates. The notorious i finally won acceptance and was put to use in complex analysis and theoretical physics in Napoleonic times. Addressing readers with both a general and scholarly interest in mathematics, Nahin weaves into this narrative entertaining historical facts and mathematical discussions, including the application of complex numbers and functions to important problems, such as Kepler's laws of planetary motion and ac electrical circuits. This book can be read as an engaging history, almost a biography, of one of the most evasive and pervasive "numbers" in all of mathematics.

A critical look at the risk measurement tool that has repeatedly hurt the financial world The Number That Killed Us finally tells the "greatest story never told": how a mysterious financial risk measurement model has ruled the world for the past two decades and how it has repeatedly, and severely, caused market, economic, and social turmoil. This model was the key factor behind the unleashing of the cataclysmic credit crisis that erupted in 2007 and which the effects are still being felt around the world. The Number That Killed Us is the first and only book to thoroughly explain this hitherto-uncovered phenomenon, making it the key reference for truly understanding why the malaise took place. The very number financial institutions and regulators use to measure risk (Vale at Risk/VaR) has masked it, allowing firms to leverage up their speculative bets to unimaginable levels. VaR sanctioned and allowed the monstrously geared toxic punts that sank Wall Street, and the world, during the latest crisis. We can confidently say that VaR was the culprit. In The Number That Killed Us, derivatives expert Pablo Triana takes you through the development of VaR and shows how its inevitable structural flaws allowed banks to take on even greater risks. The precise role of VaR in igniting the latest crisis is thoroughly covered, including in-depth analysis of how and why regulators, by falling in love with the tool, condemned us to chaos. Uncritically embraced worldwide for way too long, VaR is, in the face of such destruction, just starting to be examined as problematic, and in this book Triana (long an open critic of the tool's role in encouraging mayhem) uncovers exactly why it makes our financial world a more dangerous place. If we care for our safety, we should let VaR go. Contains controversial analysis of the hotly debated risk metric Value at Risk (VaR) and its central role in the credit crisis Denounces the role of regulators and academics in forcing the presence of the inevitably malfunctioning in financeland Describes how bonus-hungry traders can use VaR as an alibi to take on the most reckless of bets Reveals how the most recent financial crisis will simply repeat itself if the problems behind VaR are not unmasked Pablo Triana is also the author of Lecturing Birds on Flying The very risk measurement tool that was intended to contain risk allowed financial firms to blindly take on more. The model that was supposed to save us condemned us to misery. The Number That Killed Us reveals how this has happened and what needs to be done to correct the situation.

"In Great Dames, Marie Benner introduces us to a pantheon of women whose lives are both gloriously individual and yet somehow universal. Her subjects range from Jacqueline Kennedy Onassis, who found happiness in her last decade, to Constance Baker Motley, who argued Brown versus the Board of Education before the United States Supreme Court, to Luise Rainer, who won two Academy Awards by age thirty, then fled Hollywood for good. We meet Kitty Carlisle Hart, a professional charmer and tireless advocate of the arts, and Diana Trilling, the intellectual's intellectual, who published her final, splendid memoir at age ninety-one. There are even the Becky Sharps, who maneuvered powerful men to help them ascend: Marietta Tree, Pamela Harriman, and Clare Boothe Luce. And the wonderfully flamboyant Kay Thompson, whose pint-sized creation, Eloise, gave her a place in American cultural history. Finally, there is Thelma Brenner, who was the first great dame her daughter ever knew." "These are women who helped shape a century. Marie Brenner's portraits are intimate, vivid, and true, and full of subtle but important lessons. The way the great dames lived their lives - their rules, their codes, their insistence on certain fundamentals - are models that today's women should consider as they ascend to positions of leadership in a new millennium."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
