The Guardian's Best Science Book of 2017: the fascinating science and history of the air we breathe. It's invisible. It's ever-present. Without it, you would die in minutes. And it has an epic story to tell. In Caesar's Last Breath, New York Times bestselling author Sam Kean takes us on a journey through the periodic table, around the globe, and across time to tell the story of the air we breathe, which, it turns out, is also the story of earth and our existence on it. With every breath, you literally inhale the history of the world. On the ides of March, 44 BC, Julius Caesar died of stab wounds on the Senate floor, but the story of his last breath is still unfolding; in fact, you're probably inhaling some of it now. Of the sextillions of molecules entering or leaving your lungs at this moment, some might well bear traces of Cleopatra's perfumes, German mustard gas, particles exhaled by dinosaurs or emitted by atomic bombs, even remnants of stardust from the universe's creation. Tracing the origins and ingredients of our atmosphere, Kean reveals how the alchemy of air reshaped our continents, steered human progress, powered revolutions, and continues to influence everything we do. Along the way, we'll swim with radioactive pigs, witness the most important chemical reactions humans have discovered, and join the crowd at the Moulin Rouge for some of the crudest performance art of all time. Lively, witty, and filled with the astounding science of ordinary life, Caesar's Last Breath illuminates the science stories swirling around us every second.

From New York Times bestselling author Sam Kean comes incredible stories of science, history, finance, mythology, the arts, medicine, and more, as told by the Periodic Table. Why did Gandhi hate iodine (I, 53)? How did radium (Ra, 88) nearly ruin Marie Curie's reputation? And why is gallium (Ga, 31) the go-to element for laboratory pranksters? The Periodic Table is a crowning scientific achievement, but it's also a treasure trove of adventure, betrayal, and obsession. These fascinating tales follow every element on the table as they play out their parts in human history, and in the lives of the (frequently) mad scientists who discovered them. The Disappearing Spoon masterfully fuses science with the classic lore of invention, investigation, and discovery -- from the Big Bang through the end of time. Though solid at room temperature, gallium is a moldable metal that melts at 84 degrees Fahrenheit. A classic science prank is to mold gallium spoons, serve them with tea, and watch guests recoil as their utensils disappear.

Could the killing of Germanicus Julius Caesar—the grandson of Mark Antony, adopted son of the emperor Tiberius, father of Caligula, and grandfather of Nero—while the Roman Empire was still in its infancy have been the root cause of the empire's collapse more than four centuries later? This brilliant investigation of Germanicus Caesar’s death and its aftermath is both a compelling history and first-class murder mystery with a plot twist Agatha Christie would envy.

A lively exploration of the joys of a not-so-dead language From the acclaimed novelist and Oxford professor Nicola Gardini, a personal and passionate look at the Latin language: its history, its authors, its essential role in education, and its enduring impact on modern life—whether we call it “dead” or not. What use is Latin? It’s a question we’re often asked by those who see the language of Cicero as no more than a cumbersome heap of ruins, something to remove from the curriculum. In this sustained meditation, Gardini gives us his sincere and brilliant reply: Latin is, quite simply, the means of expression that made us—and continues to make us—who we are. In Latin, the rigorous and inventive thinker Lucretius examined the nature of our world; the poet Propertius told of love and emotion in a dizzying variety of registers; Caesar affirmed man’s capacity to shape reality through reason; Virgil composed the Aeneid, without which we’d see all of Western history in a different light. In Long Live Latin, Gardini shares his deep love for the language—enriched by his tireless intellectual curiosity—and warmly encourages us to engage with a civilization that has never ceased to exist, because it’s here with us now, whether we know it or not. Thanks to his careful guidance, even without a single lick of Latin grammar readers can discover how this language is still capable of restoring our sense of identity, with a power that only useless things can miraculously express.

In this story of the most famous assassination in history, “the last bloody day of the [Roman] Republic has never been painted so brilliantly” (The Wall Street Journal). Julius Caesar was stabbed to death in the Roman Senate on March 15, 44 BC—the Ides of March according to the Roman calendar. He was, says author Barry Strauss, the last casualty of one civil war and the first casualty of the next civil war, which would end the Roman Republic and inaugurate the Roman Empire. “The Death of Caesar provides a fresh look at a well-trodden event, with superb storytelling sure to inspire awe” (The Philadelphia Inquirer). Why was Caesar killed? For political reasons, mainly. The conspirators wanted to return Rome to the days when the Senate ruled, but Caesar hoped to pass along his new powers to his family, especially Octavian. The principal plotters were Brutus, Cassius (both former allies of Pompey), and Decimus. The last was a leading general and close friend of Caesar’s who felt betrayed by the great man: He was the mole in Caesar’s camp. But after the assassination everything went wrong. The killers left the body in the Senate and Caesar’s allies held a public funeral. Mark Antony made a brilliant speech—not “Friends, Romans, Countrymen” as Shakespeare had it, but something inflammatory that caused a riot. The conspirators fled Rome. Brutus and Cassius raised an army in Greece but Antony and Octavian defeated them. An original, new perspective on an event that seems well known, The Death of Caesar is “one of the most riveting hour-by-hour accounts of Caesar’s final day I have read....An absolutely marvelous read” (The Times, London).

From one of the world's most beloved writers and New York Times bestselling author of A Walk in the Woods and The Body, a vivid, nostalgic, and utterly hilarious memoir of growing up in the 1950s. Bill Bryson was born in the middle of the American century—1951—in the middle of the United States—Des Moines, Iowa—in the middle of the largest generation in American history—the baby boomers. As one of the best and funniest writers alive, he is perfectly positioned to mine his memories of a totally all-American childhood for 24-carat memoir gold. Like millions of his generational peers, Bill Bryson grew up with a rich fantasy life as a superhero. In his case, he ran around his house and neighborhood with an old football jersey with a thunderbolt on it and a towel about his neck that served as his cape, leaping tall buildings in a single bound and vanquishing awful evildoers (and morons)—in his head—as "The Thunderbolt Kid." Using this persona as a springboard, Bill Bryson re-creates the life of his family and his native city in the 1950s in all its transcendent normality—a life at once completely familiar to us all and as far away and unreachable as another galaxy. It was, he reminds us, a happy time, when automobiles and televisions and appliances (not to mention nuclear weapons) grew larger and more numerous with each passing year, and DDT, cigarettes, and the fallout from atmospheric testing were considered harmless or even good for you. He brings us into the life of his loving but eccentric family, including affectionate portraits of his father, a gifted sportswriter for the local paper and dedicated practitioner of isometric exercises, and of his mother, whose job as the home furnishing editor for the same paper left her little time for practicing the domestic arts at home. The many readers of Bill Bryson’s earlier classic, A Walk in the Woods, will greet the reappearance in these pages of the immortal Stephen Katz, seen hijacking literally boxcar loads of beer. He is joined in the Bryson gallery of immortal characters by the demonically clever Willoughby brothers, who apply their scientific skills and can-do attitude to gleefully destructive ends. Warm and laugh-out-loud funny, and full of his inimitable, pitch-perfect observations, The Life and Times of the Thunderbolt Kid is as wondrous a book as Bill Bryson has ever written. It will enchant anyone who has ever been young.

From New York Times bestselling author Sam Kean comes the gripping, untold story of a renegade group of scientists and spies determined to keep Adolf Hitler from obtaining the ultimate prize: a nuclear bomb. Scientists have always kept secrets. But rarely have the secrets been as vital as they were during World War II. In the middle of building an atomic bomb, the leaders of the Manhattan Project were alarmed to learn that Nazi Germany was far outpacing the Allies in nuclear weapons research. Hitler, with just a few pounds of uranium, would have the capability to reverse the entire D-Day operation and conquer Europe. So they assembled a rough and motley crew of geniuses -- dubbed the Alsos Mission -- and sent them careening into Axis territory to spy on, sabotage, and even assassinate members of Nazi Germany's feared Uranium Club. The details of the mission rival the finest spy thriller, but what makes this story sing is the incredible cast of characters -- both heroes and rogues alike -- including: Moe Bergm, the major league catcher who abandoned the game for a career as a multilingual international spy; the strangest fellow to ever play professional baseball. Werner Heisenberg, the Nobel Prize-winning physicist credited as the discoverer of quantum mechanics; a key contributor to the Nazi's atomic bomb project and the primary target of the Alsos mission. Colonel Boris Pash, a high school science teacher and veteran of the Russian Revolution who fled the Soviet Union with a deep disdain for Communists and who later led the Alsos mission. Joe Kennedy Jr., the charismatic, thrill-seeking older brother of JFK whose need for adventure led him to volunteer for the most dangerous missions the Navy had to offer. Samuel Goudsmit, a washed-up physics prodigy who spent his life hunting Nazi scientists -- and his parents, who had been swept into a concentration camp -- across the globe. Irène and Frederic Joliot-Curie, a physics Nobel-Prize winning power couple who used their unassuming status as scientists to become active members of the resistance. Thrust into the dark world of international espionage, these scientists and soldiers played a vital and largely untold role in turning back one of the darkest tides in human history.
