Leonard Mlodinow takes us on a passionate and inspiring tour through the exciting history of human progress and the key events in the development of science. In the process, he presents a fascinating new look at the unique characteristics of our species and our society that helped propel us from stone tools to written language and through the birth of chemistry, biology, and modern physics to today’s technological world.   Along the way he explores the cultural conditions that influenced scientific thought through the ages and the colorful personalities of some of the great philosophers, scientists, and thinkers: Galileo, who preferred painting and poetry to medicine and dropped out of university; Isaac Newton, who stuck needlelike bodkins into his eyes to better understand changes in light and color; and Antoine Lavoisier, who drank nothing but milk for two weeks to examine its effects on his body. Charles Darwin, Albert Einstein, Werner Heisenberg, and many lesser-known but equally brilliant minds also populate these pages, each of their stories showing how much of human achievement can be attributed to the stubborn pursuit of simple questions (why? how?), bravely asked.  The Upright Thinkers is a book for science lovers and for anyone interested in creative thinking and in our ongoing quest to understand our world. At once deeply informed, accessible, and infused with the author’s trademark wit, this insightful work is a stunning tribute to humanity’s intellectual curiosity.  (With black-and-white illustrations throughout.)

    Nobody is perfect. And that includes five of the greatest scientists in history—Charles Darwin, William Thomson (Lord Kelvin), Linus Pauling, Fred Hoyle, and Albert Einstein. But the mistakes that these great luminaries made helped advance science. Indeed, as Mario Livio explains, science thrives on error, advancing when erroneous ideas are disproven.As a young scientist, Einstein tried to conceive of a way to describe the evolution of the universe at large, based on General Relativity—his theory of space, time, and gravity. Unfortunately he fell victim to a misguided notion of aesthetic simplicity. Fred Hoyle was an eminent astrophysicist who ridiculed an emerging theory about the origin of the universe that he dismissively called “The Big Bang.” The name stuck, but Hoyle was dead wrong in his opposition.They, along with Darwin (a blunder in his theory of Natural Selection), Kelvin (a blunder in his calculation of the age of the earth), and Pauling (a blunder in his model for the structure of the DNA molecule), were brilliant men and fascinating human beings. Their blunders were a necessary part of the scientific process. Collectively they helped to dramatically further our knowledge of the evolution of life, the Earth, and the universe.

    It expands on the foundation acquired in chemistry courses and enables students to understand the mechanisms as they come across them in your classroom or laboratory.Organic Reaction Mechanisms provides extensive coverage of various organic reaction and rearrangements with emphasis on their applications in syntheses. The authors discuss reaction pathways, such as substitutions, additions, eliminations, oxidations, reductions, aromatic substitutions, aliphatic nucleophilic substitution, and electrophilic substitutions with numerous reaction equations to show the mechanism. The text also details the various reaction intermediates, including carbocations, carbanions, free radicals, carbenes, nitrines, benzynes, arynes, ylides, and enamines.Furthermore, the reagents are surveyed throughout the text, and correlation tables are provided to aid in identifying which oxidation/reduction agents to use for oxidizing/reducing various types of compounds. The applications of organic reagents are illustrated with examples and problems at the end of each chapter, which also serve to review the mechanisms learned and topics discussed. A comprehensive discussion on organic reactions, Organic Reaction Mechanisms will benefit advanced undergraduate and graduate chemistry students in their understanding and application of organic syntheses.

    Priestley represented a unique synthesis: by the 1780s, he had established himself as one of the world's most celebrated scientists, most prominent religious figures, and most outspoken political thinkers. Yet he would also have become one of the most hated men in all of his native England. When an angry mob burned down his house in Birmingham, Priestley and his family set sail for Pennsylvania.In the nascent United States, Priestley hoped to find the freedom to bridge the disciplines that had governed his life, to find a quiet lab and a receptive pulpit. Once he arrived, as a result of his close relationships with the Founding Fathers—Jefferson credited Priestley as the man who prevented him from abandoning Christianity—Priestley found himself at the center of what would go down as one of the seminal debates in American history. And as Johnson brilliant charts, Priestley exerted profound if little-known influence on the shape and course of this great experiment in nation-building.As in his most recent bestselling work, The Ghost Map, Steven Johnson here uses a dramatic historical story to explore themes that have long engaged him: innovation and the way new ideas emerge and spread, and the environments that foster these breakthroughs. As he did in Everything Bad is Good for You, he upsets some fundamental assumptions about the world we live in—namely, what it means when we invoke the Founding Fathers—and replaces them with a clear-eyed, eloquent assessment of where we stand today.

    A THOROUGH STUDY OF THE BOOK WILL ENSURE EXCELLENT SUCCESS AT ALL LEVELS.

    Johnson takes us to those times when the world seemed filled with mysterious forces, when scientists were dazzled by light, by electricity, and by the beating of the hearts they laid bare on the dissecting table. We see Galileo singing to mark time as he measures the pull of gravity, and Newton carefully inserting a needle behind his eye to learn how light causes vibrations in the retina. William Harvey ties a tourniquet around his arm and watches his arteries throb above and his veins bulge below, proving that blood circulates. Luigi Galvani sparks electrical currents in dissected frog legs, wondering at the twitching muscle fibers, and Ivan Pavlov makes his now-famous dogs salivate at ascending chord progressions.For all of them, diligence was rewarded. In an instant, confusion was swept aside and something new about nature leaped into view. In bringing us these stories, Johnson restores some of the romance to science, reminding us of the existential excitement of a single soul staring down the unknown.

    Written by Curie’s daughter, the renowned international activist Eve Curie, this biography chronicles Curie’s legendary achievements in science, including her pioneering efforts in the study of radioactivity and her two Nobel Prizes in Physics and Chemistry. It also spotlights her remarkable life, from her childhood in Poland, to her storybook Parisian marriage to fellow scientist Pierre Curie, to her tragic death from the very radium that brought her fame. Now updated with an eloquent, rousing introduction by best-selling author Natalie Angier, this timeless biography celebrates an astonishing mind and a extraordinary woman’s life.

    A twenty-eight year old — and not widely famous — Christopher Wren was giving a lecture on astronomy. As his audience listened to him speak, they decided that it would be a good idea to create a Society to promote the accumulation of useful knowledge.With that, the Royal Society was born. Since its birth, the Royal Society has pioneered scientific exploration and discovery. Isaac Newton, Charles Darwin, Albert Einstein, Robert Hooke, Robert Boyle, Joseph Banks, Humphry Davy, Isambard Kingdom Brunel, John Locke, Alexander Fleming — all were fellows.Bill Bryson’s favourite fellow was Reverend Thomas Bayes, a brilliant mathematician who devised Bayes’ theorem. Its complexity meant that it had little practical use in Bayes’ own lifetime, but today his theorem is used for weather forecasting, astrophysics and stock market analysis. A milestone in mathematical history, it only exists because the Royal Society decided to preserve it — just in case. The Royal Society continues to do today what it set out to do all those years ago. Its members have split the atom, discovered the double helix, the electron, the computer and the World Wide Web. Truly international in its outlook, it has created modern science.Seeing Further celebrates its momentous history and achievements, bringing together the very best of science writing. Filled with illustrations of treasures from the Society’s archives, this is a unique, ground-breaking and beautiful volume, and a suitable reflection of the immense achievements of science.

    Silver translates our most important, and often most obscure, scientific developments into a vernacular that is not only accessible and illuminating but also enjoyable. Silver makes his comprehensive case with much clarity and insight; his book aptly locates science as the apex of human reason, and reason as our best path to the truth. For all readers curious about--or else perhaps intimidated by--what Silver calls the scientific campaign up to now in his Preface, The Ascent of Science will be fresh, vivid, and fascinating reading.

    It was the government, led by the Social Democratic Party, which took power, albeit with some trepidation, after Kaiser Wilhelm II abdicated the German throne. Socialists saw this as the opportunity they had been waiting for, the day when workers would be the ones in power. For the conservatives who could not accept the German defeat in World War I, however, the Weimar Republic was a feeble entity which had capitulated to Germany’s enemies.The German Revolution of 1918-1919 told the story of a bruised nation attempting to overcome its military defeat at the hands of enemies who wanted to punish Germany for starting the war. Because Germany was caught in the vise of such irreconcilable political philosophies between the left and the right, the Weimar Republic, although it was the ruling power following the German Revolution, was destined to have a doomed, short life in Germany’s tragic twentieth-century history.

    This empire dominates western Europe from 800 until 1806, when it is defeated by Napoleon. The Second Reich: All of Germany is united behind Prussia under the leadership of Otto von Bismarck, victor of the Franco-Prussian War. Only Germany's defeat in World War I can break the power of the second German empire.What was the Third Reich?In 1933, Adolf Hitler was appointed Chancellor of Germany after convincing other members of the Reichstag that the Nazi party was better for the country than their feared rivals, the Communists. Within the year, the President of the German Republic will be dead, and Hitler will declare himself supreme leader of Germany.But how did it happen?The Third Reich: Adolf Hitler, Nazi Germany, World War II and The Last German Empire takes you on a guided tour of German history for the last thousand years. You'll study the constitution of the Weimar republic and the Treaty of Versailles, and come to understand why Hitler believed it was crucial to build a new Nazi empire that was second to no one other nation in Europe in terms of military development. You'll learn how Hitler used the rhetoric of racism and nationalism to transform himself from a democratically elected member of government into a dictator whose word was law.Most importantly, you'll learn how those changes paved the way to World War II and the atrocities of the Holocaust.

    He believed that rogues were in his house. I offered to help him to search the property, to which Gruber replied that he was not afraid.” Sometime during the evening of the 31st March 1922, at an isolated farmstead deep in rural Germany, five members of the same family, alongside their maid, were brutally slain in their own home, hacked to death with a short handled pickaxe. The killings stunned a Bavaria already racked by the aftermath of war and hyper-inflation. Almost a century on the murders remain unsolved. In this, the first in depth English language investigation into the slayings, Edward Chilvers attempts to separate myth from fact, relying on contemporary police sources and witness statements to paint a picture of an insular, incestuous family who, for reasons as yet unknown, took it upon themselves to ignore the numerous warnings of what was to come in the days leading up to their demise.

    These noteworthy accounts of the lives of David Hilbert and Richard Courant are closely related: Courant's story is, in many ways, seen as the sequel to the story of Hilbert. Originally published to great acclaim, both books explore the dramatic scientific history expressed in the lives of these two great scientists and described in the lively, nontechnical writing style of Contance Reid.
