Allein in unserer Galaxie gibt es etwa eine Milliarde erdähnlicher Planeten. Im sichtbaren Universum finden sich etwa 200 Milliarden Galaxien. Liegt es daher nicht nahe, dass sich irgendwo da draußen eine Zivilisation entwickelt hat, die mindestens genauso fortgeschritten ist wie unsere eigene? Die schieren Zahlen verlangen fast danach. Aber: Wieso sind wir dann noch nicht auf Botschaften, Artefakte oder sonstige Hinweise auch nur einer einzigen außerirdischen Zivilisation gestoßen? In diesem Buch führt Stephen Webb durch fünfzig überzeugende und faszinierende Lösungen des berühmten Fermi-Paradoxons, die kurzweilig präsentiert zum Nachdenken und auch Schmunzeln anregen.
This book presents the reader with some of the earliest classic SF short
stories - all of them published between 1858 and 1934, featuring both well-
known and long-forgotten writers - dealing for the first time with topics to
which science had (some) answers only at much later stages.
Exploring the evolution of symbols, this book delves into the rich history of characters like the ampersat and ampersand, alongside smileys and runes. It highlights the significance of both well-known and obscure glyphs in various contexts, showcasing their presence in historical and contemporary documents across sciences and technology. The text offers insights into how these symbols have shaped communication and understanding throughout time.
"It has been argued that science fiction (SF) gives a kind of weather forecast - not the telling of a fortune but rather the rough feeling of what the future might be like. The intention in this book is to consider some of these bygone forecasts made by SF and to use this as a prism through which to view current developments in science and technology. In each of the ten main chapters - dealing in turn with antigravity, space travel, aliens, time travel, the nature of reality, invisibility, robots, means of transportation, augmentation of the human body, and, last but not least, mad scientists - common assumptions once made by the SF community about how the future would turn out are compared with our modern understanding of various scientific phenomena and, in some cases, with the industrial scaling of computational and technological breakthroughs. A further intention is to explain how the predictions and expectations of SF were rooted in the scientific orthodoxy of their day, and use this to explore how our scientific understanding of various topics has developed over time, as well as to demonstrate how the ideas popularized in SF subsequently influenced working scientists."--Back cover

In a 1950 conversation at Los Alamos, four world-class scientists generally agreed, given the size of the Universe, that advanced extraterrestrial civilizations must be present. But one of the four, Enrico Fermi, asked, "If these civilizations do exist, where is everybody?" Given the fact that there are perhaps 400 million stars in our Galaxy alone, and perhaps 400 million galaxies in the Universe, it stands to reason that somewhere out there, in the 14 billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. Webb discusses in detail the 50 most cogent and intriguing solutions to Fermi's famous paradox.
