A young woman finished a doctoral thesis in 1925 and answered the oldest question anyone has ever asked about the sky: what are the stars made of? Her answer was hydrogen. Overwhelmingly, almost comically, hydrogen, with a generous helping of helium and a rounding error of everything else...

Hoe zag de elektrische auto er al in 1835 uit?In deze aflevering het bijzondere verhaal van het wagentje van de Groningse hoogleraar Sybrandus Stratingh. Hij combineerde een vroege batterij met een elektromotor en bouwde zo het eerste elektrische karretje dat daadwerkelijk rondreed.Het wagentje past bijna in een schoenendoos en kon ongeveer twintig minuten rijden. De beperkte batterijcapaciteit bleek een groot probleem. Toch zien we in Stratingh’s uitvinding een vraagstuk dat ook vandaag nog actueel is: hoe maak je elektrische aandrijving krachtig genoeg voor praktisch gebruik?Conservator ...

Horror Stories by Howard Phillips Lovecraft. Howard Phillips Lovecraft (August 20, 1890 – March 15, 1937) was an American author of weird fiction and horror, best known for originating the subgenre of cosmic horror, which emphasizes humanity's cosmic insignificance amid indifferent, ancient entities beyond human comprehension. Born and raised in Providence, Rhode Island, spending most of his life there, Lovecraft published most of his stories in pulp magazines like Weird Tales during the 1920s and 1930s, achieving little financial success or widespread recognition before his death from ...

Horror stories are narrative works designed to evoke fear, dread, or terror in the audience, tracing back to ancient civilizations like Mesopotamia and Egypt. Origins and History: • Ancient Roots: The earliest written narratives, such as the Epic of Gilgamesh (circa 1700 BCE), feature monsters, ghosts, and underworld journeys. Early ghost and demon tales also appeared in ancient Greek, Roman, and Egyptian texts. • Gothic Tradition: Modern literary horror began during the 18th-century Gothic era. Horace Walpole's novel The Castle of Otranto (1765) established the genre, while Mary ...

The National Aeronautics and Space Administration - NASA - was established on July 29, 1958. Ever since that day, NASA has been at the forefront of efforts to explore outer space, resulting in the Apollo missions to the moon, the Skylab space-station, and today's space shuttle. But behind the open face of NASA, there is a much more mysterious world. NASA has been linked to a wealth of high-level cover-ups.

Over 50 years ago, astronomers launched the world's first orbiting telescope. This allowed them to gaze further into outer space and examine anything that appears in the sky above our heads, from comets and planets to galaxy clusters and stars. Since then, almost 100 space telescopes have been...

Stephen Hawking is one of the most remarkable figures of our time, a Cambridge genius who has earned international celebrity as a brilliant theoretical physicist and become an inspiration and revelation to those who have witnessed his courageous triumph over disability. This is Hawking's life story by Kitty Ferguson, who has had special help from Hawking himself and his close associates and who has a gift for translating the language of theoretical physics for non-scientists.

Dieses Hörbuch nimmt Sie mit auf eine Reise durch das Leben des Physikers Richard Feynman und beschreibt eindrucksvoll, welche wegweisenden wissenschaftlichen Beiträge der Nobelpreisträger zur Entwicklung der modernen Physik geleistet hat. Feynman war ein Querdenker, der immer versucht hat, den Dingen auf den Grund zu gehen. Dabei entwickelte er eine intuitive Anschauung, die seinesgleichen sucht und die ihn zu einem der großen Vermittler von physikalischen Gesetzen machte. Der Autor Jörg Resag fängt diese Entwicklung ein und erklärt sie im Rahmen des Zeitgeistes der modernen Physik.

On October 4, 1957, a time of Cold War paranoia, the Soviet Union secretly launched the Earth's first artificial moon. No bigger than a basketball, the tiny satellite was powered by a car battery. Yet, for all its simplicity, Sputnik stunned the world.

An inspiring collection of essays, in which Albert Einstein addresses the topics that fascinated him as a scientist, philosopher, and humanitarian. Divided by subject matter - “Science,” “Convictions and Beliefs,” “Public Affairs,” etc. - these essays consider everything from the need for a “supranational” governing body to control war in the atomic age, to freedom in research and education, to Jewish history and Zionism, to explanations of the physics and scientific thought that brought him world recognition.

Quantum physics is notable for its brazen defiance of common sense. (Think of Schrödinger's Cat, famously both dead and alive.) An especially rigorous form of quantum contradiction occurs in experiments with entangled particles. Our common assumption is that objects have properties whether or not anyone is observing them, and the measurement of one can't affect the other. Quantum entanglement rejects this assumption, offering impeccable reasoning and irrefutable evidence of the opposite. Is quantum entanglement mystical, or just mystifying?

For decades, beloved astrophysicist Neil deGrasse Tyson has interpreted science with a combination of brainpower and charm that resonates with fans everywhere. This pioneering, provocative audiobook brings together the best of StarTalk, his beloved podcast and television show devoted to solving the most confounding mysteries of Earth, space, and what it means to be human. 

“Da qualche anno la mia ricerca si è concentrata sui buchi bianchi, elusivi fratelli minori dei buchi neri. Questo è il mio libro sui buchi bianchi. Provo a raccontare come sono fatti i buchi neri, che vediamo nel cielo a centinaia. Cosa accade sul bordo di queste strane stelle, l’orizzonte, dove il tempo appare rallentare fino a fermarsi e lo spazio sembra strapparsi. Poi giù, dentro, nelle regioni più interne, fin dove tempo e spazio si sciolgono. Fin dove è come rimbalzare indietro nel tempo. Fin dove nascono i buchi bianchi.”

The third installment and possibly our most challenging audiobook of the series! But, of course, you will be the judge. We dug deeper, flew further, and sorted through tons of cosmic dust to bring you another 601 mind-blowing facts. You’ll laugh, you’ll cheer, and you’ll cry…well, you’re not likely to cry, but the dedicated astronomers have uncovered space successes as well as losses. Inside, you will find 165 trivia questions to challenge students, the avidly curious novice, and above.

When people look up into the night sky, the stars seem fixed and immutable, as unchanging as the darkness of space itself, but the truth is that stars are born, live, and die in a never-ending cycle of creation and annihilation. These cycles stretch over such vast spans of time that to short-lived humans, they seem to last forever. No one knows just how many stars there are, but their number is almost beyond comprehension.

Max Tegmark leads us on an astonishing journey through past, present and future, and through the physics, astronomy and mathematics that are the foundation of his work, most particularly his hypothesis that our physical reality is a mathematical structure and his theory of the ultimate...

In this 12-lecture masterpiece of scientific reporting, you'll learn everything you need to know to fully grasp the significance of this discovery, including the basics of quantum mechanics; the four forces that comprise the Standard Model of particle physics; how these forces are transmitted by fields and particles; and the importance of symmetry in physics.

At once elegant and riveting, Sync tells the story of the dawn of a new science. Steven Strogatz, a leading mathematician in the fields of chaos and complexity theory, explains how enormous systems can synchronize themselves, from the electrons in a superconductor to the pacemaker cells in our hearts. He shows that although these phenomena might seem unrelated on the surface, at a deeper level there is a connection, forged by the unifying power of mathematics.
