At the 1993 Battle of Mogadishu, dramatized by the popular film Black Hawk Down, the majority of soldiers who died were killed instantly or bled to death before they could reach an operating table. This tragedy reinforced the need for a revolutionary treatment that could transform trauma medicine. So, when Frank Hursey and Bart Gullong—who had no medical or military experience—discovered that a cheap, crushed rock called zeolite had blood‑clotting properties, they brought it to the military's attention. The Marines and the Navy adopted the resulting product, QuikClot, immediately.

Weathercaster “Nor’EasterNick” Pittman tells his heartfelt story of learning to embrace the unpredictable and turn rainy days into opportunities.

Sixty-five years ago, a middle-aged woman working with a small group of collaborators out of a converted shed on the outskirts of Cambridge predicted the future of Artificial Intelligence. As world powers raced to discover and exploit the capabilities of the first computers during the Cold War, Masterman emerged from obscurity to become an unlikely prophet of artificial intelligence.

A compelling account of Ruben Miller's years working as a forensic scientist, visiting crime scenes and gathering evidence. His detailed descriptions of what he sees are often heart-breaking. The behaviour of the people he meets—lawyers, police, the media and even the occasional suspect—is always fascinating and occasionally hilarious. Insights into the techniques of forensic science give a fascinating view of what it can and can't do vs what the public, and even legal experts, expect.

Protagonizada pelo brasileiro Eduardo Saverin, estudante de economia, e pelo norte-americano Mark Zuckerberg, gênio da informática–amigos que sobreviviam num ambiente repleto de alunos brilhantes de famílias supertradicionais–este audiolivro mostra a trajetória da criação da rede social que se tornou uma das mais poderosas empresas do mundo e que revolucionou a maneira como milhões de pessoas se relacionam.

The last 20 years have brought us the rise of the Internet, the development of artificial intelligence, the ubiquity of once unimaginably powerful computers, and the thorough transformation of our economy and society. Through it all, Ellen Ullman lived and worked inside that rising culture of technology, and in Life in Code she tells the continuing story of the changes it wrought with a unique, expert perspective.

Today, the world is in the midst of the transformative and ever-developing Digital Age, otherwise referred to as the “Age of Information.” It has been an unprecedented, remarkable, and explosive era marked by social media and computer-generated imagery (and with it, deep fakes), among other novel, previously unimaginable concepts. The bulky monitors and blocky towers of personal computers and laptops, which were once upon a time considered fashionable, futuristic contraptions, have since been replaced with a sleek and stylish array.

Werner Heisenberg was one of the greatest physicists of all time. He probed the depths of not just science but the nature of our very existence. His groundbreaking work in quantum mechanics, particularly the formulation of the uncertainty principle, revolutionized our understanding of the subatomic world and earned him the Nobel Prize in Physics in 1932.

Fusion GPS was founded in 2010 by Glenn Simpson and Peter Fritsch, two former reporters at The Wall Street Journal who decided to abandon the struggling news business and use their reporting skills to conduct open-source investigations for businesses and law firms - and opposition research for political candidates. In the fall of 2015, they were hired to look into the finances of Donald Trump.

Il est impossible aujourd'hui de passer à côté du phénomène Musk. Elon Musk, c'est l'homme qui rêve en grand et promet à l'humanité qu'elle va quitter le berceau Terre, direction Mars. En seulement quelques années, il s'est imposé dans tous les grands champs de la science contemporaine. Il révolutionne le secteur spatial avec SpaceX, il prend position sur l'intelligence artificielle, souhaite transformer les neurosciences en connectant des ordinateurs à nos cerveaux, et joue les influenceurs pour le développement des monnaies virtuelles.

Edwin Grosvenor writes of Bell's other extraordinary inventions: the first transmission of sound over light waves, metal detector, first practical phonograph, and early airplanes, including the first to fly in Canada. He also examines Bell's humanitarian efforts, including support for women's suffrage, civil rights, and speeches about what he warned would be a "greenhouse effect" of pollution causing global warming.

Dr. Temple Grandin gets to the real issues of autism, the ones parents, teachers, and individuals on the spectrum face every day. Temple offers helpful dos and don'ts, practical strategies, and try-it-now tips, all based on her insider perspective and a great deal of research.

Asked to name a great physicist, most people would mention Newton or Einstein, Feynman or Hawking. But ask a physicist and there’s no doubt that James Clerk Maxwell will be near the top of the list. Maxwell, an unassuming Victorian Scotsman, explained how we perceive color. He uncovered the way gases behave. And, most significantly, he transformed the way physics was undertaken in his explanation of the interaction of electricity and magnetism, revealing the nature of light and laying the groundwork for everything from Einstein’s special relativity to modern electronics.

Thomas Edison passed on many decades ago, but his inventions still echo loudly through time. If you watch TV, listen to your favorite songs, or simply click on the lamp next to your bed, it was Thomas Edison who brought all of these innovations into the world. Inside you will hear about Edison's early life, the electric light, the war of the currents, other inventions and projects, his final years and death, Edison's legacy, and much more.

For astronaut Ron Garan, living on the International Space Station was a powerful, transformative experience - one that he believes holds the key to solving our problems here on Earth. On space walks and through windows, Garan was struck by the stunning beauty of the Earth from space but sobered by knowing how much needed to be done to help this troubled planet.

Dorothy Hodgkin (1910-1994) was renowned for her medically-important work on penicillin, vitamin B12 and insulin. Fully engaged with the political and social currents of her time, she participated in some of the greatest upheavals of the 20th century: women's education; the globalisation of science; the rise and fall of communism; and international peace movements. A wife, mother and grandmother, she cared deeply about the well-being of individuals in all cultures.

“We are as gods and might as well get good at it.” These are the opening lines that radical thinker, environmentalist, and technologist Stewart Brand wrote for The Whole Earth Catalog. His thesis—that humans should use our god-like powers to build a better way to live—is at the core of his extraordinary life. At key historical moments in the 20th century, Stewart Brand was behind the scenes shaping things. As founding editor of Wired Magazine Kevin Kelly says, “Stewart has a Forest Gump-like superpower—he can sense where the future is and be there.”

In Traversal, her startling and moving new book, Maria Popova traverses the border between life and death, chance and choice, chemistry and consciousness: What makes a body a person? What makes a planet a world? How do we safeguard our love of truth from our lust for power? What slakes our longings and what redeems our losses?

Stephen Hawking has dazzled listeners worldwide with a string of best sellers exploring the mysteries of the universe.

Gran físico italiano, es famoso principalmente por haber desarrollado la pila eléctrica en 1800, un invento que asombró al mundo entero. Hoy, en mérito a su labor, la unidad de fuerza electromotriz del Sistema Internacional de Unidades lleva el nombre de voltio en su honor desde el año 1881, y desde 1964 la UAI decidió en su honor llamarle Volta a un astroblema lunar.
