Beginning with an obscure discovery in 1896, radioactivity led researchers on a quest for understanding that ultimately confronted the intersection of knowledge and mystery. Mysterious from the start, radioactivity attracted researchers who struggled to understand it. What caused certain atoms to give off invisible, penetrating rays? Where did the energy come from? These questions became increasingly pressing when researchers realized the process seemed to continue indefinitely, producing huge quantities of energy. Investigators found cases where radioactivity did change, forcing them to the startling conclusion that radioactive bodies were transmuting into other substances. Chemical elements were not immutable after all. Radioactivity produced traces of matter so minuscule and evanescent that researchers had to devise new techniques and instruments to investigate them. Scientists in many countries, but especially in laboratories in Paris, Manchester, and Vienna unraveled the details of radioactive transformations. They created a new science with specialized techniques, instruments, journals, and international conferences. Women entered the field in unprecedented numbers. Experiments led to revolutionary ideas about the atom and speculations about atomic energy. The excitement spilled over to the public, who expected marvels and miracles from radium, a scarce element discovered solely by its radioactivity. The new phenomenon enkindled the imagination and awakened ancient themes of literature and myth. Entrepreneurs created new industries, and physicians devised novel treatments for cancer. Radioactivity gave archaeologists methods for dating artifacts and meteorologists a new explanation for the air's conductivity. Their explorations revealed a mysterious radiation from space. Radioactivity profoundly changed science, politics, and culture. The field produced numerous Nobel Prize winners, yet radioactivity's talented researchers could not solve the mysteries underlying the new phenomenon. That was left to a new generation and a new way of thinking about reality. Radioactivity presents this fascinating history in a way that is both accessible and appealing to the general reader. Not merely a historical account, the book examines philosophical issues connected with radioactivity, and relates its topics to broader issues regarding the nature of science.

    This is Nick's story of his world record-breaking adventure and the extraordinary people who joined him along the way. On January 6th 2018, Nick Butter tied his laces and stepped out on to an icy pavement in Toronto, where he began to take the first steps of an epic journey that would see him run 196 marathons in every one of the world's 196 countries. Spending almost two years on the road and relying on the kindness of strangers to keep him moving, Nick's odyssey allowed him to travel slowly, on foot, immersing himself in the diverse cultures and customs of his host nations. Running through capital cities and deserts, around islands and through spectacular landscapes, Nick dodges bullets in Guinea-Bissau, crosses battlefields in Syria, survives a wild dog attack in Tunisia and runs around an erupting volcano in Guatemala. Along the way, he is often joined by local supporters and fellow runners, curious children and bemused passers-by. Telling their stories alongside his own, Nick captures the unique spirit of each place he visits and forges a new relationship with the world around him. Running the World captures Nick's journey as he sets three world records and covers over five thousand miles. As he recounts his adventures, he shares his unique perspective on our glorious planet, celebrates the diversity of human experience, and reflects on the overwhelming power of running.

    To the public he is a figure of tragic dimensions - a brilliant scientist and author of the phenomenal best-seller A Brief History of Time, and yet confined to a wheelchair, unable to speak or write. Hawking has mastered the two great theories of 20th-century physics - Einstein's General Theory of Relativity and Quantum Mechanics - and has made breathtaking discoveris about where they break down or overlap, such as on the edge of a Black Hole or at the Big Bang origin of the Universe. Here is the perfect introduction to Hawking's work by the author, who was helped by several long discussions with Hawking in researching the book.

    With clear explanations of some of the most complex scientific endeavors in history, Mahaffey's new book looks back at the atom's wild, secretive past and then toward its potentially bright future.Mahaffey unearths lost reactors on far flung Pacific islands and trees that were exposed to active fission that changed gender or bloomed in the dead of winter. He explains why we have nuclear submarines but not nuclear aircraft and why cold fusion doesn't exist. And who knew that radiation counting was once a fashionable trend? Though parts of the nuclear history might seem like a fiction mash-up, where cowboys somehow got a hold of a reactor, Mahaffey's vivid prose holds the reader in thrall of the infectious energy of scientific curiosity and ingenuity that may one day hold the key to solving our energy crisis or sending us to Mars.

    His first was that nothing can travel faster than light-the ultimate speed limit. This simple fact leads to the unavoidable conclusion that space and time must be linked together forever as Spacetime. With his second monumental insight, Einstein showed how Spacetime is warped and stretched by the gravity of all objects in the Universe and even punctured by black holes. But such possible twisting of Spacetime allowed a magic not even Einstein could have imagined: time-travel.Theoretical physicist Jim Al-Khalili finally lays science fiction to rest as he opens up Einstein's Universe. Leading us gently and light-heartedly through the dizzying world of our space and time, he even gives us the recipe for a time machine, capable of taking us Back to the Future, to Alice's Wonderland, or on a trip with the Terminator.

    Wolke, professor emeritus of chemistry at the University of Pittsburgh and acclaimed author of What Einstein Didn't Know, understands the need to...well, understand. Now he provides more amusing explanations of such everyday phenomena as gravity (If you're in a falling elevator, will jumping at the last instant save your life?) and acoustics (Why does a whip make such a loud cracking noise?), along with amazing facts, belly-up-to-the-bar bets, and mind-blowing reality bites all with his trademark wit and wisdom.If you shoot a bullet into the air, can it kill somebody when it comes down? You can find out about all this and more in an astonishing compendium of the proverbial mind-boggling mysteries of the physical world we inhabit.Arranged in a question-and-answer format and grouped by subject for browsing ease, WHAT EINSTEIN TOLD HIS BARBER is for anyone who ever pondered such things as why colors fade in sunlight, what happens to the rubber from worn-out tires, what makes red-hot objects glow red, and other scientific curiosities. Perfect for fans of Newton's Apple, Jeopardy!, and The Discovery Channel, WHAT EINSTEIN TOLD HIS BARBER also includes a glossary of important scientific buzz words and a comprehensive index. -->

    But in the scalp of a balding man, they do not get everything they need and as a result, the hair-producing cells gradually die off. Here we have an example of a mild ‘disease’ which is caused by cellular malnutrition.” —Dr. Roger J. Williams “A living cell requires energy not only for all of its functions, but also for maintenance of its structure.” —Nobel Laureate Albert Szent-Györgyi "What could be more important to understand than biological energy? Thought, growth, movement, every philosophical and practical issue involves the nature of biological energy.” —Raymond Peat, PhD ======== The Current View of Pattern Hair Loss is Unproductive (and Dangerous) While it is often stated with great confidence that pattern pattern hair loss is the result of defective genes and "male" androgenic hormones (e.g., dihydrotestosterone or DHT), the theory is physiologically unsound. After 60 years of research the "genetic-androgen" hypoheses has produced a single FDA-approved "therapy" that works less than 50% the time and can result in permanent chemical castration (Minoxidil is a nonstarter for many men and women). In contrast, castrates and pseudohermaphrodites--who serve as the foundation for all baldness research--are protected from pattern hair loss 100% of the time. Steps Towards a 'Bioenergetic' View of Pattern Hair Loss Standing on the shoulders of giants (e.g., Otto Warburg, Albert Szent-Györgyi, Gilbert Ling, Ray Peat and others), HAIR LIKE A FOX sets up an alternative 'bioenergetic model' of pattern hair loss with a focus on the smallest unit of life, the cell. This same context elucidates simple yet effective therapies for halting and perhaps reversing pattern hair loss in a way that harmonizes with our unique physiology.
