From the plains of ancient Mesopotamia to the rolling hills of medieval England to the vast sheep farms of modern-day Australia, sheep have been central to the human story. Starting with our Neolithic ancestors' first forays into sheep-rearing nearly 10,000 years ago, these remarkable animals have fed us, clothed us, changed our diet and languages, helped us to win wars, decorated our homes and financed the conquest of large swathes of the earth.

Dos médicos en la misma ciudad pueden dar diagnósticos diferentes a pacientes idénticos; dos jueces pueden dictar sentencias distintas ante delitos similares; nosotros mismos podemos decidir una cosa u otra según sea por la mañana o por la tarde, o según se acerque o no la hora de comer. Estos son ejemplos de ruido: el sesgo que conlleva variabilidad en juicios que deberían ser iguales.

Informative, entertaining, and upbeat, this audiobook continues Grazier and Cass’ exploration of how technology, science, and scientists are portrayed in Hollywood productions. Both big and small-screen productions are featured and their science content illuminated - first by the authors and subsequently by a range of experts from science and the film world. Starring roles in this volume are played by, among other things, computers (human and mechanical), artificial intelligences, robots, and spacecraft.

Lighthearted, quirky, and upbeat, this book explores the portrayal of science and technology on both the big and little screen - and how Hollywood is actually doing a better job of getting it right than ever before. Grounded in the real-word, and often cutting-edge, science and technology that inspires fictional science, the authors survey Hollywood depictions of topics such as quantum mechanics, parallel universes, and alien worlds.

Que se passe-t-il dans une étoile ? Quel est son rôle dans la galaxie et dans l'économie générale de l'Univers ?Des centrales nucléaires qui transforment les éléments...Les étoiles ont toujours été chères au cœur des poètes et des enfants. L'astrophysique donne une explication rationnelle à cette admiration. Elle révèle que les étoiles sont les mères des atomes. Elles brillent parce qu'elles transmettent les éléments et s'ouvrent comme des fleurs. Elles inséminent l'espace de légions d'atomes qui ont pour nom carbone, azote, oxygène, magnésium, fer, uranium.

We prefer not to talk about it, but we should. Disease spread by waste kills more people worldwide every year than any other single cause of death. Even in America, nearly two million people have no access to an indoor toilet. Yet the subject remains unmentionable. Moving from the underground sewers of Paris, London, and New York (an infrastructure disaster waiting to happen) to an Indian slum where ten toilets are shared by 60,000 people, The Big Necessity breaks the silence, revealing everything that matters about how people do - and don't - deal with their own waste.

THE INTERNATIONAL BEST SELLER FEATURING INTERVIEWS WITH DR ANTHONY FAUCI, DAME SALLY DAVIES AND DR JIM DOWN For every doctor there is that one patient, whose story touches them in a way they didn’t expect, changing their entire outlook on life. This inspiring and deeply moving book is the...

Blood carries life, yet the sight of it makes people faint. It is a waste product and a commodity pricier than oil. It can save lives and transmit deadly infections. Each one of us has roughly nine pints of it, yet many don’t even know their own blood type. And for all its ubiquitousness, the few tablespoons of blood discharged by 800 million women are still regarded as taboo: menstruation is perhaps the single most demonized biological event.

Just 45 years ago, the age of gene modification was born. Researchers could create glow-in-the-dark mice, farmyard animals producing drugs in their milk, and vitamin-enhanced rice that could prevent half a million people going blind every year. But now GM is rapidly being supplanted by a new system called CRISPR or "gene editing". Using this approach, scientists can manipulate the genes of almost any organism with a degree of precision, ease and speed that we could only dream of ten years ago.

The explorers featured in this volume include: Michele Dougherty, the mathematician who persuaded the Cassini mission to Saturn to make a diversion; Richard Fortey on his love of trilobites; Monica Grady, Meteorite Lady; neurosurgeon Henry Marsh on slicing through our thoughts; the Director of the British Antarctic Survey, Jane Francis; Jocelyn Bell Burnell describing how she missed out on a Nobel Prize; Brian Cox on quantum mechanics; and Nobel Prize winner John Sulston on why he thought it would be a good idea to sequence the human genome.
