Heisenberg’s principle implied that scientific quantities/concepts do not have absolute, independent meaning, but acquire meaning only in terms of the experiments used to measure them. This proposition, undermining the cherished belief that science could reveal the physical world with limitless detail and precision, placed Heisenberg in direct opposition to the revered Albert Einstein. The eminent scientist Niels Bohr, Heisenberg’s mentor and Einstein’s long-time friend, found himself caught between the two.Uncertainty chronicles the birth and evolution of one of the most significant findings in the history of science, and portrays the clash of ideas and personalities it provoked. Einstein was emotionally as well as intellectually determined to prove the uncertainty principle false. Heisenberg represented a new generation of physicists who believed that quantum theory overthrew the old certainties; confident of his reasoning, Heisenberg dismissed Einstein’s objections. Bohr understood that Heisenberg was correct, but he also recognized the vital necessity of gaining Einstein’s support as the world faced the shocking implications of Heisenberg’s principle.

    Their dramatic lives are here unfolded in a rich historical biography certain to appeal to fans of Downton Abbey, ‘Georgiana’ and Stella Tillyard’s ‘Aristocrats’.Mary, Madeline and Pamela – the three Wyndham sisters – were painted by John Singer Sargent in 1899. For The Times it was, quite simply, ‘the greatest picture of modern times’. But these beautiful, fin de siecle gentlewomen came to epitomize a vanished world. The languor of their pose reflects the leisured, gilded, existence of the late Victorian aristocracy that was to be dealt a deathblow by the First World War.Yet the lives of these three Wyndham sisters were far more turbulent than their air of calm suggests. Brought up in artistic circles, their childhood was liberal and romantic. Their parents were intimate friends with the Pre-Raphaelites and the girls grew to become leaders of the aesthetic movement. Bowing to convention, they made excellent marriages but found emotional support from others – Mary with Arthur Balfour and the poet Wilfrid Scawen Blunt; Pamela with Liberal statesman and ornithologist Edward Grey. Their liaisons shocked society, while the First World War devastated their way of life.‘Those Wild Wyndhams’ is their first ever biography, and is based on the many letters they have left behind – compelling, humorous and brilliantly illuminating. This sparkling debut by Claudia Renton captures them and their age in an unforgettable piece of historical and political biography.

    What happened during those years and what has happened since to refine the understanding of this phenomenon is the fascinating story told here.We move from a coffee shop in Zurich, where Einstein and Max von Laue discuss the madness of quantum theory, to a bar in Brazil, as David Bohm and Richard Feynman chat over cervejas. We travel to the campuses of American universities—from J. Robert Oppenheimer’s Berkeley to the Princeton of Einstein and Bohm to Bell’s Stanford sabbatical—and we visit centers of European physics: Copenhagen, home to Bohr’s famous institute, and Munich, where Werner Heisenberg and Wolfgang Pauli picnic on cheese and heady discussions of electron orbits.Drawing on the papers, letters, and memoirs of the twentieth century’s greatest physicists, Louisa Gilder both humanizes and dramatizes the story by employing their own words in imagined face-to-face dialogues. Here are Bohr and Einstein clashing, and Heisenberg and Pauli deciding which mysteries to pursue. We see Schrödinger and Louis de Broglie pave the way for Bell, whose work is here given a long-overdue revisiting. And with his characteristic matter-of-fact eloquence, Richard Feynman challenges his contemporaries to make something of this entanglement.

    She found a way of being a respected sovereign in an age when people were deeply uncomfortable with having a woman on the throne.As well as a queen, Victoria was a daughter, a wife, a mother and a widow, and at each of these steps along life's journey she was expected to conform to what society demanded of a woman. On the face of it, she was deeply conservative. But if you look at her actions rather than her words, she was in fact tearing up the rule book for how to be female. By looking at the detail of twenty-four days of her life, through diaries, letters and more, we can see Victoria up close and personal. Examining her face-to-face, as she lived hour to hour, allows us to see, and to celebrate, the contradictions at the heart of British history's most recognisable woman.

    Herndon aspired to write a faithful portrait of his friend and law partner, Abraham Lincoln, based on his own observations and on hundreds of letters and interviews he had compiled for the purpose. Even more importantly, he was determined to present Lincoln as a man, rather than a saint, and to reveal things that the prevailing Victorian conventions said should be left out of the biography of a great national hero. A variety of obstacles kept Herndon from writing his book, however, and not until he found a collaborator in Jesse W. Weik did the biography begin to take shape. It finally appeared in 1889, to decidedly mixed reviews. Though controversial from the outset, "Herndon's Lincoln" nonetheless established itself as a classic, and remains, as Don E. Fehrenbacher declared, "the most influential biography of Lincoln ever published." This new edition restores the original text, includes two chapters added in the revised (1892) edition, and traces the story of how this landmark biography got written. Extensive annotation affords the reader a detailed look at the biography's sources.

    When he emerged three years later, the summation of his efforts only hinted at what he'd experienced in one of the most dangerous regions on earth. Armed with an astonishing collection of zoological specimens, Du Chaillu leapt from the physical challenges of the jungle straight into the center of the biggest issues of the time--the evolution debate, racial discourse, the growth of Christian fundamentalism--and helped push each to unprecedented intensities. He experienced instant celebrity, but with that fame came whispers--about his past, his credibility, and his very identity--which would haunt the young man. Grand in scope, immediate in detail, and propulsively readable, Between Man and Beast brilliantly combines Du Chaillu's personal journey with the epic tale of a world hovering on the sharp edge of transformation.

    'Wonderfully imaginative' Bernard Cornwell, author of The Last Kingdom. Perfect for fans of Simon Scarrow and Bernard Cornwell.James Keane - card sharp and ladies' man - is one of the finest soldiers of Wellington's army. Keane - hot-tempered, a maverick, never quite accepted by his fellow officers - is in trouble for killing his man in a duel: an activity forbidden by Wellington. To avoid court martial, he takes on an unwelcome assignment: to form an ill-assorted bunch of reprobates into an elite unit capable of operating behind the lines. A nineteenth-century Dirty Dozen.

    Until Mary's incredible discovery, it was widely believed that animals did not become extinct. The child of a poor family, Mary became a fossil hunter, inspiring the tongue-twister, "She Sells Sea Shells by the Seashore." She attracted the attention of fossil collectors and eventually the scientific world. Once news of the fossils reached the halls of academia, it became impossible to ignore the truth. Mary's peculiar finds helped lay the groundwork for Charles Darwin's theory of evolution, laid out in his On the Origin of Species. Darwin drew on Mary's fossilized creatures as irrefutable evidence that life in the past was nothing like life in the present.A story worthy of Dickens, The Fossil Hunter chronicles the life of this young girl, with dirt under her fingernails and not a shilling to buy dinner, who became a world-renowned paleontologist. Dickens himself said of Mary: "The carpenter's daughter has won a name for herself, and deserved to win it."Here at last, Shelley Emling returns Mary Anning, of whom Stephen J. Gould remarked, is "probably the most important unsung (or inadequately sung) collecting force in the history of paleontology," to her deserved place in history.

    . . . Readers will never again look into the night sky the same way.” —MICHAEL SHERMER, author of The Believing Brain on Parallax: The Race to Measure the CosmosIn 1930, Edwin Hubble announced the greatest discovery in the history of astronomy since Galileo first turned a telescope to the heavens. The galaxies, previously believed to float serenely in the void, are in fact hurtling apart at an incredible speed; the universe is expanding. This stunning discovery was the culmination of a decades-long arc of scientific and technical advancement. In its shadow lies an untold, yet equally fascinating, backstory whose cast of characters illuminates the gritty, hard-won nature of scientific progress.The path to a broader mode of cosmic observation was blazed by a cadre of 19th-century amateur astronomers and inventors, galvanized by the advent of photography, spectral analysis, and innovative technology to create the entirely new field of astrophysics. From William Bond, who turned his home into a functional observatory, to John and Henry Draper, a father and son team who were trailblazers of astrophotography and spectroscopy, to geniuses of invention such as Léon Foucault, and George Hale, who founded the Mount Wilson Observatory, Hirshfeld reveals the incredible stories—and the ambitious dreamers—behind the birth of modern astronomy.Alan Hirshfeld, Professor of Physics at the University of Massachusetts Dartmouth and an Associate of the Harvard College Observatory, is the author of Parallax: The Race to Measure the Cosmos, The Electric Life of Michael Faraday, and Eureka Man: The Life and Legacy of Archimedes.

    Yet in Three Armies on the Somme, William Philpott makes a convincing argument that the battle ultimately gave the British and French forces on the Western Front the knowledge and experience to bring World War I to a victorious end.It was the most brutal fight in a war that scarred generations. Infantrymen lined up opposite massed artillery and machine guns. Chlorine gas filled the air. The dead and dying littered the shattered earth of no man’s land. Survivors were rattled with shell-shock. We remember the shedding of so much young blood and condemn the generals who sent their men to their deaths. Ever since, the Somme has been seen as a waste: even as the war continued, respected leaders—Winston Churchill and David Lloyd George among them—judged the battle a pointless one. While previous histories have documented the missteps of British command, no account has fully recognized the fact that allied generals were witnessing the spontaneous evolution of warfare even as they sent their troops “over the top.” With his keen insight and vast knowledge of military strategy, Philpott shows that twentieth-century war as we know it simply didn’t exist before the Battle of the Somme: new technologies like the armored tank made their battlefield debut, while developments in communications lagged behind commanders’ needs. Attrition emerged as the only means of defeating industrialized belligerents that were mobilizing all their resources for war. At the Somme, the allied armies acquired the necessary lessons of modern warfare, without which they could never have prevailed. An exciting, indispensable work of military history that challenges our received ideas about the Battle of the Somme, and about the very nature of war.

    Let us determine to die here and we will conquer. Rally behind them!” With these words Gen. B. E. Bee of the Confederates States Army inspired the famous nickname for Gen. T. J. Jackson, and his brigade, at the First Battle of Bull Run: Stonewall. Three months earlier the 2d, 4th, 5th and 27th Virginia Infantry Regiments had been brigaded together with the 33rd, in whose “A” Company John O. Casler was serving as a Private.However, their reputation came at a cost: if there was an extra hard duty, Jackson would send in his old brigade lest he be thought of as favouring them.Drawn from his diary at the time, Casler recounts his experiences in the ranks, from marches and looting to nail-biting escapades and the monotony of life as a prisoner of war. Instead of a history of the war, Four Years in the Stonewall Brigade is a remarkable account of men in war, graphically bringing to light the challenges they faced on a daily basis.Praise for Four Years in the Stonewall Brigade“…as illustrating the daily life of a soldier in the ranks it is one of the very best publications I have read. I found it a vivid reminder of the days gone by…” — E. M. Schutte, late Sergeant Company C, 13th Massachusetts.“Your style is clear and entertaining. It will do all the old boys of both sides good to read it.” — J. G. Winne, late 16th New York Horse Artillery.“This is to certify that John O. Casler belonged to Company A, 33d Virginian Infantry, Stonewall Brigade. John was a good soldier, always ready and willing to perform any duty assigned him.” — W. H. Powell, Captain Company A, 33d Virginian Infantry, Stonewall Brigade.John O. Casler (1838-1926) was an American soldier and author born in Frederick County, Virginia. While he had left the family home aged twenty one, when it seemed that war was imminent he returned and enlisted in the Confederate States Army in June 1861. Following the war he emigrated to Sherman, Texas. For details of other books published by Albion Press go to the website at www.albionpress.co.uk.

    Whatever it is, we call it matter or material substance. It is solid; it has mass. But what is matter, exactly? We are taught in school that matter is not continuous, but discrete. As a few of the philosophers of ancient Greece once speculated, nearly two and a half thousand years ago, matter comes in 'lumps', and science has relentlessly peeled away successive layers of matter to reveal its ultimate constituents.Surely, we can't keep doing this indefinitely. We imagine that we should eventually run up against some kind of ultimately fundamental, indivisible type of stuff, the building blocks from which everything in the Universe is made. The English physicist Paul Dirac called this 'the dream of philosophers'. But science has discovered that the foundations of our Universe are not as solid or as certain and dependable as we might have once imagined. They are instead built from ghosts and phantoms, of a peculiar quantum kind. And, at some point on this exciting journey of scientific discovery, we lost our grip on the reassuringly familiar concept of mass.How did this happen? How did the answers to our questions become so complicated and so difficult to comprehend? In Mass Jim Baggott explains how we come to find ourselves here, confronted by a very different understanding of the nature of matter, the origin of mass, and its implications for our understanding of the material world. Ranging from the Greek philosophers Leucippus and Democritus, and their theories of atoms and void, to the development of quantum field theory and the discovery of a Higgs boson-like particle, he explores our changing understanding of the nature of matter, and the fundamental related concept of mass.

    To his contemporaries he was a minor disciple of Emerson; he has since joined the ranks of America's most respected and beloved writers. Few, however, really know the complexity of the man they revere — wanderer and scholar, naturalist and humorist, teacher and surveyor, abolitionist and poet, Transcendentalist and anthropologist, inventor and social critic, and, above all, individualist.In this widely acclaimed biography, outstanding Thoreau scholar Walter Harding presents all of these Thoreaus. Scholars will find here the culmination of a lifetime of research and study, meticulously documented; general readers will find an absorbing story of a remarkable man. Writing always with supreme clarity, Professor Harding has marshaled all the facts so as best to "let them speak for themselves." Thoreau's thoughtfulness and stubbornness, his more than ordinarily human amalgam of the earthy and the sublime, his unquenchable vitality emerge to the reader as they did to his own family, friends, and critics.You will see Thoreau's work in his family's pencil factory, his accidental setting of a forest fire, his love of children and hatred of hypocrisy, his contributions to the scientific understanding of forest trees, and other more and less familiar aspects of the man and his works. You will find the social as well as the reclusive Thoreau. Reactions to him by such notable contemporaries as Margaret Fuller, Nathaniel Hawthorne, and Walt Whitman — with Thoreau's responses to them — are given in rich detail.The totality is as complete, accurate, fair, vivid, and fully rounded a portrait as has ever been drawn. On its appearance, Professor Harding's work immediately established itself as "the standard biography" (Edward Wagenknecht). It has never been superseded. For this Dover edition, the author has corrected minor errors, provided an appendix bibliographically documenting hundreds of facts, and contributed an Afterword updating some of his findings and discussing Thoreau scholarship.

    The 1866 title story, by Australian writer Mary Fortune, is the first known detective story by a woman, a suspenseful clue-strewn manhunt in the Outback. Pioneer writers Anna Katharine Green and C. L. Pirkis take you from high society New York to bustling London, introducing colorful detectives such as Violet Strange and Loveday Brooke.In another forgotten classic, November Joe, the Canadian half-Native backwoods detective who stars in Hesketh Prichard's "The Crime at Big Tree Portage," demonstrates that Sherlockian attention to detail works as well in the woods as in the city. Holmes himself is here, too, of course-not in another reprint of an already well-known story, but in the first two chapters of A Study in Scarlet, the first Holmes case, in which the great man meets and dazzles Watson.Introduced by Michael Sims's insightful overview of detective fiction, The Dead Witness unfolds the irresistible antecedents of what would mature into the most popular genre of the twentieth century.
