The Story of the Universe in 100 Stars
Visit one hundred extraordinary stars that unveil the mysteries of the universe Our own Sun—a source of awe, myth, and mystery for untold generations of sky-gazers—is just one of roughly two hundred billion trillion stars. Together, they’re a window into the profoundest questions in physics—overturning, again and again, how we understand light, matter, time, and existence itself. Florian Freistetter explains all this and more, in brief, easy-to-read profiles of the hundred most history-making stars, inviting readers to gaze into the past and future of the universe alongside a stellar cast of scientists— from Annie Jump Cannon, who revolutionized how we classify the stars, to Dorrit Hoffleit, who first counted them. Enjoy your journey through the cosmos . . . GRB 080319B, the farthest we’ve seen into space with the naked eye V1364 CYGNI, pivotal in the discovery of dark matter 72 Tauri, definitive evidence for Einstein’s theory of relativity Algol, called the Demon Star for its mysterious blinking—and many more! Publisher’s note: 100 Stars That Explain the Universe was previously published in hardcover as The Story of the Universe in 100 Stars.
A History of the Universe in 100 Stars
From the Big Bang to the Gaia Mission, this is a very personal history of the universe through the author's favourite 100 stars. Astronomer Florian Freistetter has chosen 100 stars that have almost nothing in common. Some are bright and famous, some shine so feebly you need a huge telescope. There are big stars, small stars, nearby stars and faraway stars. Some died a while ago, others have not even yet come into being. Collectively they tell the story of the whole world, according to Freistetter. There is Algol, for example, the Demon Star, whose strange behaviour has long caused people sleepless nights. And Gamma Draconis, from which we know that the earth rotates around its own axis. There is also the star sequence 61 Cygni, which revealed the size of the cosmos to us. Then there are certain stars used by astronomers to search for extra-terrestrial life, to explore interstellar space travel, or to explain why the dinosaurs became extinct. In 100 short, fascinating and entertaining chapters, Freistetter not only reveals the past and future of the cosmos, but also the story of the people who have tried to understand the world in which we live.
Stephen Hawking
A science writer explains the significance of Stephen Hawking's work--in terms all of us can understand. Stephen Hawking was one of the most important astrophysicists of the last fifty years. After the publication of A Brief History of Time, he became an international celebrity. Though the book sold in the millions, few readers really grasped the significance of his groundbreaking work. Now popular Austrian science blogger Florian Freistetter, himself an astronomer, makes Hawking's contributions accessible to everyday readers in this concise, very readable book. By focusing on the essentials, Freistetter deftly and entertainingly makes Hawking's complex theoretical accomplishments understandable. Avoiding technicalities and jargon, he elucidates the great scientist's fascinating work on black holes, gravitational waves, the big bang, and singularities. Concluding with an appreciation of Hawking as a science communicator and popularizer, Freistetter conveys the importance of Hawking's scientific research in terms that nonspecialists can follow.
Chaos and Stability in Planetary Systems
This book is intended as an introduction to the field of planetary systems at the postgraduate level. It consists of four extensive lectures on Hamiltonian dynamics, celestial mechanics, the structure of extrasolar planetary systems and the formation of planets. As such, this volume is particularly suitable for those who need to understand the substantial connections between these different topics.
White Skin, Black Fuel
Rising temperatures and the rise of the far right. What disasters happen when they meet? In the first study of the far right’s role in the climate crisis, White Skin, Black Fuel presents an eye-opening sweep of a novel political constellation, revealing its deep historical roots. Fossil-fuelled technologies were born steeped in racism. No one loved them more passionately than the classical fascists. Now right-wing forces have risen to the surface, some professing to have the solution—closing borders to save the nation as the climate breaks down. Epic and riveting, White Skin, Black Fuel traces a future of political fronts that can only heat up.
Fact and Prejudice
When having coffee with your family, you are offered energized water. On Twitter you discuss with vaccination opponents. The WhatsApp kitagroup discusses zodiac signs, the pharmacy sells you globules, the neighbor proselytizes for her guru, and the news is once again about demonstrations by right-wing extremists. Everywhere you encounter conspiracy myths, superstition, esotericism, pseudoscience and Co. and you want to respond to them - while remaining as factual as possible, clarify your position, provide facts, but also not unnecessarily provoke or overload. In addition, you do not want to hurt your counterpart, but to encourage him to rethink. But how do you do that? If you are asking you...
The Secret of Ishango
The Ishango bones were found in the 1950s by Belgian archaeologist Jean de Heinzelin near a Palaeolithic residence in Ishango, Africa. The inscriptions in the bones, which can be interpreted as numbers, are unique in their complexity in human history. Interestingly, on one of the two Ishango bones, we also find the six consecutive prime numbers 5, 7, 11, 13, 17 and 19. Did Stone Age people already know the secret of the prime numbers? This question is explored in my mathematical essay "The Secret of Ishango Bones", an adventurous journey around the world from Basel in Switzerland to Erode in India. The presumed connection between the numbers on the Ishango bones and the structure of the prim...
