Trous noirs, exoplanètes, les nouvelles techniques d'observation en astronomie ont permis d'extraordinaires découvertes. Une résolution beaucoup plus fine des images. Durant les dernières décennies, de nouveaux instruments d'observation situés sur Terre et dans l'espace ont, grâce à des progrès dans la résolution des images, donné lieu à des découvertes extraordinaires. Trous noirs et exoplanètes : des découvertes extraordinaires. Pierre Léna décrit ici ces innovations instrumentales et s'attarde sur deux découvertes majeures récentes.

Einstein et l'espace-temps. Jusqu'aux premières années du XXe siècle, l'espace et le temps sont perçus comme les catégories préexistantes dans lesquelles se manifeste tout le contenu de l'univers : la matière sous toutes ses formes et la force à l'origine de toutes les interactions de la matière. Relativité et théorie quantique Les révolutions conceptuelles du début du XXe siècle initiées par Einstein, relativité et théorie quantique, vont changer radicalement ces notions et les relations qu'elles entretiennent entre elles.

Neues vom Bestsellerautor von Das Universum für Eilige: Wie schaut der Kosmos auf die menschliche Zivilisation? In einer Zeit der gesellschaftlichen Spaltung blickt der Star-Astrophysiker Neil deGrasse Tyson mit der kosmischen Brille auf die Menschheit und zeigt auf, was uns auf der Erde politisch und kulturell zusammenschweißt. Gleichzeitg liefert er ein leidenschaftliches Plädoyer für wissenschaftliches und rationales Denken ab.

Claude Cohen-Tannoudji, prix Nobel de physique 1997, retrace son itinéraire personnel et scientifique et un demi-siècle d'évolution de la physique quantique. Sur ce sujet nul n'est mieux placé que lui, qui en a extrait les applications les plus caractéristiques et les plus étonnantes à la fois: la domestication –; et en particulier le refroidissement –; des atomes à l'aide de la lumière. La genèse de ces résultats révolutionnaires –; dont les applications commencent seulement à poindre aujourd'hui –; constitue un témoignage unique sur le développement de la physique et des techniques du XXè siècle.

Une histoire des notions d'espace et de temps. Des visions du cosmos dans la Grèce ancienne aux théories récentes sur la gravité quantique, Carlo Rovelli explore les métamorphoses de la notion d'espace et de temps. Une approche lumineuse de l'histoire des sciences par le biais de ces " coordonnées fondamentales de notre description du monde ". L'espace et le temps dans la physique contemporaine.

Au début du 17è siècle, Galilée est le fondateur emblématique de la science moderne. Par ses observations astronomiques, il nous fait passer du monde clos et géocentrique hérité de l'Antiquité à l'Univers pluri-centrique et infini d'aujourd'hui.C'est aussi le premier physicien véritablement expérimentateur, qui posera les bases de la mécanique moderne et de la théorie de la résistance des matériaux.

Книга рассказывает о жизни людей в далекой середине XX века, о формировании увлекательной науки о мозге человека, о тех, кто в мимолетных встречах на научных форумах или в теснейших контактах повседневной работы обогатил своими мыслями и трудом изучение сложнейшего создания на нашей планете — мозга человека. В книге — о расшифровке законов активности здорового и больного мозга и о приложимости этих законов не только в медицине, но и к событиям социального порядка государственного масштаба.

Immortality: A User's Guide takes listeners on a thrilling journey through recent scientific history and reveals the cutting-edge technology that may help us live deep into our second centuries. Featuring insightful conversations with longevity experts, archival footage, immersive sound design, and Johnson's trademark storytelling, Immortality explores the recent paradigm shift in our understanding of aging and wrestles with what we should do, as a society, to prepare for advances in science and technology that may radically transform the potential length of human life.

Before the discovery of insulin, diabetes was treated almost exclusively through diet, from subsistence on meat, to reliance on fats, to repeated fasting and near-starvation regimens. After two centuries of conflicting medical advice, most authorities today believe that those with diabetes can have the same dietary freedom enjoyed by the rest of us, leaving the job of controlling their disease to insulin therapy and other blood-sugar-lowering medications.

The commonly held view of Albert Einstein is of an eccentric genius for whom the pursuit of science was everything. But in actuality, the brilliant innovator whose Theory of Relativity forever reshaped our understanding of time was a man of his times, always politically engaged and driven by strong moral principles. An avowed pacifist, Einstein’s mistrust of authority and outspoken social and scientific views earned him death threats from Nazi sympathizers in the years preceding World War II.

Embark on a captivating voyage through the skies with "In The Sky With Stars: A History of Air Balloons." This meticulously crafted exploration unveils the extraordinary story of humanity's quest to conquer the skies, from the pioneering days of the Montgolfier brothers to the modern frontiers of space exploration.

This momentous biography tells the story of the Huxleys: the Victorian natural historian T. H. Huxley ("Darwin's Bulldog") and his grandson, the scientist, conservationist, and zoologist Julian Huxley.

For as long as humans have lived, we have lived beneath the stars. But under the glow of today’s artificial lighting, we have lost the intimacy our ancestors once shared with the cosmos. In Starborn, cosmologist Roberto Trotta reveals how stargazing has shaped the course of human civilization. The stars have served as our timekeepers, our navigators, our muses—they were once even our gods. How radically different would we be, Trotta also asks, if our ancestors had looked up to the night sky and seen… nothing?

When the Smithsonian’s Hall of Physical Anthropology opened in 1965 it featured 160 Andean skulls affixed to a wall to visualize how the world’s human population had exploded since the birth of Christ. Through a history of Inca mummies, a preHispanic surgery called trepanation, and Andean crania like these, Empires of the Dead explains how “ancient Peruvians” became the single largest population in the Smithsonian and many other museums in Peru, the Americas, and beyond.

In the last 350-odd years, the international “scientific community” has come to be the bastion of consensus and concerted action, especially in the face of two global crises: disastrous climate change, and a deadly pandemic. How did “the scientific community” come into existence, and why does it work? Rivals is an attempt to answer these questions in the form of a brief historical overview, from the late seventeenth to the early twenty-first centuries.

From the beginning of history, measurement has been interwoven into the human experience, shaping our understanding of nature, personal relationships, and the supernatural. We measure the world to know our past, comprehend the present, and plan the future.

In his first book since the best-selling Fermat's Enigma, Simon Singh offers the first sweeping history of encryption, tracing its evolution and revealing the dramatic effects codes have had on wars, nations, and individual lives. From Mary, Queen of Scots, trapped by her own code, to the Navajo Code Talkers who helped the Allies win World War II, to the incredible (and incredibly simple) logistical breakthrough that made internet commerce secure, The Code Book tells the story of the most powerful intellectual weapon ever known: secrecy.

In our muddled era of conspiracy theories, fake news and groupthink, science's only goal is truth. Like all human pursuits it can go wrong, but it has the great strength of being self-correcting. At its best, what lasts - after much deliberation, rigour and sweat - is the truth. The story of science is how we get there. Standing on the shoulders of giants, world-renowned immunologist Luke O'Neill (aka the People's Immunologist) tells the zigzag story of how we got to this moment in human history, and what the future might hold.

A century ago, sleep was considered a state of nothingness—even a primitive habit that we could learn to overcome. Then, an immigrant scientist and his assistant spent a month in the depths of a Kentucky cave, making nationwide headlines and thrusting sleep science to the forefront of our consciousness. Award-winning journalist Kenneth Miller weaves together science and history to tell the story of four outsider scientists who took sleep science from fringe discipline to mainstream obsession through spectacular experiments, technological innovation, and single-minded commitment.
