Nel 1714 il Parlamento inglese offrì una ricompensa di ventimila sterline in oro (l'equivalente di 10 milioni di euro) a chi avesse scoperto come determinare la longitudine di una nave nell'oceano. Astronomi famosi come Galileo, Cassini, Huygens, Newton e Halley avevano cercato invano in passato una soluzione rivolgendosi alla Luna e alle stelle. La posta in palio stimolò altri ad avanzare proposte. Fu un orologiaio autodidatta, l'inglese John Harrison, a trovare la soluzione: bastava che ogni nave fosse equipaggiata con un cronometro in grado di segnare sempre l'ora "esatta", quella di Londra, ad esempio, e un semplice confronto con l'ora locale avrebbe subito fornito la longitudine della nave. Questo libro è la storia avventurosa dei quarant'anni di sforzi che furono necessari a Harrison non solo per costruire e perfezionare quel cronometro, ma per persuadere la comunità scientifica dell'efficacia del suo metodo.

The magnificent vault of stars emblazoning Earth's night skies are but an infinitesimal fraction of the hundreds of billions that inhabit our galaxy - and there are at least as many galaxies in the universe as there are stars in the Milky Way. Cosmos makes sense of this dizzying celestial panorama by exploring it one step at a time, illustrating the planets, moons, stars, nebulae, white dwarfs, black holes and other exotica that populate the heavens with some of science's most spectacular photographs. The book opens with an orbital survey of planet Earth, before venturing into the solar system heading for interstellar space and the heart of our galaxy. As the journey unfolds, the rhythms of stellar life emerge: we pass through dark clouds of dust and gas ablaze with newly smelted stars and we witness dying stars bloom and fade as planetary nebulae, or tear themselves apart as supernovae. Having crossed the Milky Way, we enter intergalactic space. Out here we watch the hidden lives of galaxies: we see them flock and cluster, forming massive conglomerations that span millions of light years, visibly warping space with their tremendous gravity. After covering an almost unimaginable 13.4 billion light years, we approach the edge of space and the dawn of time where our voyage must end, but not before we consider how the universe was born, and how it might die.

For over a millennium, Polynesians have inhabited the remote islands of the Pacific, a vast triangle from Hawaii to New Zealand to Easter Island. Before European explorers arrived, they were the sole inhabitants of these islands. Polynesians, both closely related and widely dispersed, trace their ancestry to epic voyagers who embarked on remarkable journeys across the ocean. The mystery of how these early Polynesians discovered and colonized such distant islands—without writing or metal tools—has puzzled scholars since the eighteenth century, known as the Problem of Polynesian Origins. This enigma is particularly personal for the author, whose Maori husband and sons descend from these ancient navigators. In this exploration, she delves into the rich history of these ancestors and the contributions of sailors, linguists, archaeologists, folklorists, biologists, and geographers who have sought to understand this legacy for three centuries. Blending history, geography, anthropology, and navigation science, the narrative offers a vivid tour of one of the world’s most intriguing regions, capturing the essence of Polynesian exploration and its significance in human history.

Focusing on the life and contributions of a groundbreaking female scientist, the book explores her significant impact on the field and highlights the lesser-known stories of the young women who trained in her laboratory. Through a blend of biography and historical context, it sheds light on their struggles and achievements, offering a fresh perspective on women's roles in science. The narrative emphasizes both the individual's legacy and the collective experiences of women in a male-dominated profession.

By 1514, the reclusive cleric Nicolaus Copernicus had developed an initial outline of his heliocentric theory-in which he defied common sense and received wisdom to place the sun, and not the earth, at the center of our universe, and set the earth spinning among the other planets. Over the next two decades, Copernicus expanded his theory and compiled in secret a book-length manuscript that tantalized mathematicians and scientists throughout Europe. For fear of ridicule, he refused to publish. In 1539, a young German mathematician, Georg Joachim Rheticus, drawn by rumors of a revolution to rival the religious upheaval of Martin Luther's Reformation, traveled to Poland to seek out Copernicus. Two years later, the Protestant youth took leave of his aging Catholic mentor and arranged to have Copernicus's manuscript published, in 1543, as De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres)-the book that forever changed humankind's place in the universe. In her elegant, compelling style, Dava Sobel chronicles, as nobody has, the conflicting personalities and extraordinary discoveries that shaped the Copernican Revolution. At the heart of the book is her play "And the Sun Stood Still," imagining Rheticus's struggle to convince Copernicus to let his manuscript see the light of day.

The tender, inspiring relationship between Galileo and his daughter, a nun, is revealed through letters written between the two. Reprint.

In einer Zeit, als Edison mit seiner elektrischen Glühbirne für Aufsehen sorgte, begannen Frauen an der amerikanischen Ostküste, die Gestirne zu erkunden. In den 1880er-Jahren engagierte ein Professor der Harvard University Frauen als „Computer“ am Observatorium. Dazu gehörten nicht nur Angehörige von Astronomen, sondern auch Absolventinnen neuer Frauen-Colleges und leidenschaftliche Sternbeobachterinnen. Diese Frauen leisteten Erstaunliches: Williamina Fleming, eine ledige Mutter und ehemalige Haushälterin, entdeckte rund 300 Sterne, während Antonia Maury eine eigene Klassifikation der Planeten entwickelte, die als Grundstein der modernen Astrophysik gilt. Dennoch fanden nur wenige von ihnen später die verdiente Anerkennung. Dava Sobel widmet sich in ihrem neuen Buch dem Wirken dieser ambitionierten Wissenschaftlerinnen und setzt ihnen ein Denkmal. Die Autorin hat intensiv recherchiert und präsentiert ihre Erkenntnisse auf spannende und persönliche Weise. Sobels Werk sensibilisiert die Leser für historische Geschlechterungleichheiten in der Wissenschaft und zeigt, dass unser Wissen über den Nachthimmel auf den Verdiensten beider Geschlechter beruht. Es ist ein lebendiges Porträt fast vergessener Wissenschaftlerinnen, die entscheidend zur Entwicklung der Astrophysik beitrugen.

Frank Drake ist der erste Mensch in der Geschichte, der mit Hilfe eines Radioteleskops nach anderen Zivilisationen im Weltraum forscht. Seit über 30 Jahren spielt er eine entscheidende Rolle bei der Suche nach außerirdischer Intelligenz. Dieses Buch - teils Autobiographie, teils moderner Überblick über das Themengebiet - ist für den Nicht-Spezialisten geschrieben und eine Pflichtlektüre für alle, die sich mit der aufregenden Aussicht beschäftigen - daß wir nicht allein sind.

W drugiej połowie XIX wieku Obserwatorium Harvarda zaczęło zatrudniać kobiety na stanowiskach obliczeniowców, tzw. ludzkich komputerów. Ich zadaniem było interpretowanie obserwacji teleskopowych wykonywanych co noc przez męskich pracowników instytucji. Początkowo grupa ta składała się z żon, sióstr i córek astronomów, ale wkrótce jej szeregi zasiliły absolwentki nowych college’ów dla kobiet – Vassar, Wellesley oraz Smith. Kiedy fotografia zmieniła sposób uprawiania astronomii, kobiety przeniosły uwagę z obliczeń na badanie gwiazd utrwalanych każdej nocy na szklanych płytach fotograficznych. „Szklany wszechświat”, składający się z pół miliona płyt przez dekady gromadzonych przez Uniwersytet Harvarda, umożliwił kobietom dokonanie niesamowitych odkryć, dzięki którym ich nazwiska zajęły honorowe miejsce w dziejach astronomii. Były to: Williamina Fleming, Antonia Maury, Henrietta Swan Leavitt, Annie Jump Cannon oraz Cecilia Payne. Książka Szklany wszechświat, wzbogacona fragmentami listów, dzienników i pamiętników, to ukryta historia kobiet, których wkład w rozwój astronomii na zawsze zmienił sposób rozumienia gwiazd oraz naszego miejsca we Wszechświecie.
