King of Infinite Space: Donald Coxeter, the Man Who Saved Geometry


Siobhan Roberts - 2006
    Yet geometry is so much more than shapes and numbers; indeed, it governs much of our lives—from architecture and microchips to car design, animated movies, the molecules of food, even our own body chemistry. And as Siobhan Roberts elegantly conveys in The King of Infinite Space, there can be no better guide to the majesty of geometry than Donald Coxeter, perhaps the greatest geometer of the twentieth century.Many of the greatest names in intellectual history—Pythagoras, Plato, Archimedes, Euclid— were geometers, and their creativity and achievements illuminate those of Coxeter, revealing geometry to be a living, ever-evolving endeavor, an intellectual adventure that has always been a building block of civilization. Coxeter's special contributions—his famed Coxeter groups and Coxeter diagrams—have been called by other mathematicians "tools as essential as numbers themselves," but his greatest achievement was to almost single-handedly preserve the tradition of classical geometry when it was under attack in a mathematical era that valued all things austere and rational.Coxeter also inspired many outside the field of mathematics. Artist M. C. Escher credited Coxeter with triggering his legendary Circle Limit patterns, while futurist/inventor Buckminster Fuller acknowledged that his famed geodesic dome owed much to Coxeter's vision. The King of Infinite Space is an elegant portal into the fascinating, arcane world of geometry.

The Afghan Wars In An Hour


Rupert Colley - 2011
    American, British and coalition forces have been fighting in Afghanistan since October 2001, a month following the attacks on the Twin Towers in New York. By the end of the year the war seemed won. But a decade on the ongoing conflict seems far from over.Today's conflict has historical parallels - in the nineteenth century Great Britain twice invaded Afghanistan, in 1839 and 1878. Both times they had seemingly defeated the Afghan forces only to find that the Afghan soldier, not knowing the meaning of defeat, fought back inflicting on the mighty British Empire humiliating retreats. A century later, the Soviet Union, technologically and militarily superior, also discovered to its cost that the Afghan was a tenacious foe and impossible to defeat. After a decade of conflict the Soviet Union withdrew, its military reputation in tatters. Today, Afghanistan has been in a state of constant conflict for almost four decades. When not fighting external enemies its people have fought against each other. The Civil War of 1990 to 1996, during which the Taliban emerged, was ferocious in its intensity.The coalition forces of today are embroiled in an equally unending war. But why are we still fighting in Afghanistan? What are the lessons of history? Who are the Taliban; who are the Mujahedeen, and why was Osama bin Laden so significant? These, in an hour, are the Afghan Wars.

Hitler's Jet Plane: The Me 262 Story


Mano Ziegler - 2006
    Mano Ziegler was involved from its inception and contributed to the design, testing, training and even served in it operationally. Could the ME 262 have broken the Allied supremacy in the air? Why did it take so long to come into service and why were hundreds of German pilots sacrificed in developing it? Why did the ME 262 prove not to be the unparalleled success claimed by Goering and why were German cities left dangerously exposed against Allied bombing campaigns? These are only some the important questions this new book answers. Mano Ziegler, born 7 June 1908, had a lifetime fascination with flight. At the age of eight, he wrote to Manfred Freiherr von Richthofen, the famous "Red Baron", asking to be allowed to fly with him. Richthofen even replied, telling him, "Yes, we'll fly together!". At the age of 21, he took up glider flying. He also pursued his sport of diving and was a core member of Germany's Olympic high-diving team. In 1932 and 1934 he was student world high-diving champion at the world championships in Darmstadt and Turin. When war broke out in 1939 he became a pilot in the Luftwaffe, and from 1943 until the war's end he flew the Me 163 with Erprobungskommando 16 (Operational Test Unit 16) and Jagdgeschwader 400 (Fighter Group 400). After the war he escaped from Russian captivity and - having returned to Berlin - continued to fly and write newspaper articles. In Berlin he guested as a high-wire walker with the Camilla Mayer circus troupe, walking the 24-metre high wire - without any prior training - for a newspaper article. He eventually became editor-in-chief of the Flug-Revue aviation monthly in Stuttgart and, as such, made his first supersonic flight in an English fighter aircraft in the spring of 1960. Hitler's Jet Plane fills an important gap in the history of the Luftwaffe and of aviation in general with new research which dicloses how the first ever military jet plane failed to make its mark on World War II.

A Full Cup: Sir Thomas Lipton's Extraordinary Life and His Quest for the America's Cup


Michael D'Antonio - 2010
     Today Lipton means tea. However, in his time Sir Thomas Lipton was known for much more. Raised in desperate poverty, he became rich beyond his wildest dreams. He built a global empire of markets, factories, plantations, and stockyards. And his colorful pursuit of the America's Cup trophy made him a beloved figure on both sides of the Atlantic. In A Full Cup, Michael D'Antonio tells the tale of this larger- than-life figure. Beginning with a journey across the United States just after the Civil War, Thomas J. Lipton developed the ambition and learned the business techniques that helped him create the first chain of grocery stores. Wealthy before the age of thirty, he set his sights on the tea trade, and soon his name became synonymous with his product. Lipton's great business success makes for a compelling story of innovation and achievement. Moreover, though, Lipton's most intriguing creation was a public persona-one of the first formed with the help of a modern mass media-that appealed to millions of ordinary people, as well as the elites in America and Europe. Concocting simple stunts like elephant parades, Lipton mastered the new art of obtaining free publicity. With shameless self-promotion, he became one of the world's most eligible bachelors, a patron of the poor, and ultimately reached legendary heights when he revived the competition for the America's Cup. With one losing attempt after another, the gallant Lipton, who didn't even know how to sail his own yacht, became ever more popular. D'Antonio's biography brings to vivid life this remarkable figure.

Sikhs: The Untold Agony Of 1984


Nilanjan Mukhopadhyay - 2015
    She claimed the police had inserted a stick inside her… Swaranpreet realised that she had been cruelly violated; He spoke a single sentence but repeated it twice in chaste Punjabi: ‘Please give me a turban? I want nothing else…’ These are voices begging for deliverance in the aftermath of Indira Gandhi’s assassination in October-November 1984 in which 2,733 Sikhs were killed, burnt and exterminated by lumpens in the country. Nilanjan Mukhopadhyay walks us through one of the most shameful episodes of sectarian violence in post Independent India and highlights the apathy of subsequent governments towards Sikhs who paid a price for what was clearly a state-sponsored riot. Poignant, raw and most importantly, macabre, the personal histories in the book reveal how even after three decades, a community continues to battle for its identity in its own country.

Finding Zero: A Mathematician's Odyssey to Uncover the Origins of Numbers


Amir D. Aczel - 2015
    Virtually everything in our lives is digital, numerical, or quantified. The story of how and where we got these numerals, which we so depend on, has for thousands of years been shrouded in mystery. Finding Zero is an adventure filled saga of Amir Aczel's lifelong obsession: to find the original sources of our numerals. Aczel has doggedly crisscrossed the ancient world, scouring dusty, moldy texts, cross examining so-called scholars who offered wildly differing sets of facts, and ultimately penetrating deep into a Cambodian jungle to find a definitive proof. Here, he takes the reader along for the ride.The history begins with the early Babylonian cuneiform numbers, followed by the later Greek and Roman letter numerals. Then Aczel asks the key question: where do the numbers we use today, the so-called Hindu-Arabic numerals, come from? It is this search that leads him to explore uncharted territory, to go on a grand quest into India, Thailand, Laos, Vietnam, and ultimately into the wilds of Cambodia. There he is blown away to find the earliest zero—the keystone of our entire system of numbers—on a crumbling, vine-covered wall of a seventh-century temple adorned with eaten-away erotic sculptures. While on this odyssey, Aczel meets a host of fascinating characters: academics in search of truth, jungle trekkers looking for adventure, surprisingly honest politicians, shameless smugglers, and treacherous archaeological thieves—who finally reveal where our numbers come from.

Tiananmen Square: The Making of a Protest


Vijay Gokhale - 2021
    It was 5 o'clock on the morning of 4 June. Tanks, APCs and troop trucks were sweeping down the avenue. Citizens ran for cover. Helicopters hovered above. Foreign media claimed that Chinese troops had fired into the crowds with several hundred casualties.'More than three decades later, the Tiananmen Square incident refuses to be forgotten. The events that occurred in the summer of 1989 would not only set the course for China's politics but would also re-define its relationship with the world. China's message was clear: it remained committed to market-oriented reform, but it would not tolerate any challenge to the supremacy of the Chinese Communist Party. In return for economic prosperity, the Chinese have surrendered some rights to the state. A democratic future seems far away.Vijay Gokhale, then a young diplomat serving in Beijing, was a witness to the drama that unfolded in Tiananmen Square. This unique account brings an Indian perspective on an event in China's history that the Chinese government has been eager to have the world forget.

Blockhead: The Life of Fibonacci


Joseph D'Agnese - 2010
    He was such a daydreamer that people called him a blockhead.When Leonardo grew up and traveled the world, he was inspired by the numbers used in different countries. Then he realized that many things in nature, from the number of petals on a flower to the spiral of a nautilus shell, seem to follow a certain pattern. The boy who was once teased for being a blockhead had discovered what came to be known as the Fibonacci Sequence!

Alan Turing: Unlocking the Enigma


David Boyle - 2014
    Turing’s openness about his homosexuality at a time when it was an imprisonable offense ultimately led to his untimely lo death at the age of only forty-one. In Alan Turing: Unlocking the Enigma, David Boyle reveals the mysteries behind the man and his remarkable career. Aged just 22, Turing was elected a fellow at King's College, Cambridge on the strength of a dissertation in which he proved the central limit theorem. By the age of 33, he had been awarded the OBE by King George VI for his wartime services: Turing was instrumental in cracking the Nazi Enigma machines at the top secret code breaking establishment at Bletchley Park during the Second World War.But his achievements were to be tragically overshadowed by the paranoia of the post-War years. Hounded for his supposedly subversive views and for his sexuality, Turing was prosecuted in 1952, and forced to accept the humiliation of hormone treatment to avoid a prison sentence. Just two years later, at the age of 41 he was dead. The verdict: cyanide poisoning.Was Turing’s death accidental as his mother always claimed? Or did persistent persecution drive him to take him own life?Alan Turing: Unlocking the Enigma seeks to find the man behind the science, illuminating the life of a person who is still a shadowy presence behind his brilliant achievements.

Math and the Mona Lisa: The Art and Science of Leonardo Da Vinci


Bülent Atalay - 2004
    Readers of The Da Vinci Code were given a glimpse of the mysterious connections between math, science, and Leonardo's art. Math and the Mona Lisa picks up where The Da Vinci Code left off, illuminating Leonardo's life and work to uncover connections that, until now, have been known only to scholars.Following Leonardo's own unique model, Atalay searches for the internal dynamics of art and science, revealing to us the deep unity of the two cultures. He provides a broad overview of the development of science from the dawn of civilization to today's quantum mechanics. From this base of information, Atalay offers a fascinating view into Leonardo's restless intellect and modus operandi, allowing us to see the source of his ideas and to appreciate his art from a new perspective. William D. Phillips, who won the Nobel Prize in physics in 1997, writes of the author, "Atalay is indeed a modern renaissance man, and he invites us to tap the power of synthesis that is Leonardo's model."
