Over 50 years ago, astronomers launched the world's first orbiting telescope to gaze further into outer space to 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 launched from Earth and are orbiting our planet, with 26 still active and relaying information back to us. As a result of these space-based instruments, such as NASA's iconic Hubble Space Telescope, we know much more about the universe now than we did half a century ago. But why is Hubble, orbiting just 540 kilometres above the Earth, so much more effective than a ground-based telescope? How can a glorified camera tell us not only what distant objects look like, but their detailed chemical composition and three-dimensional structure as well? In Eyes in the Sky, science writer Andrew May takes us on a journey into space to answer these questions and more by looking at the development of revolutionary instruments, such as Hubble and the James Webb Space Telescope, exploring how such technology has helped us understand the evolution of the Universe.
Astronomers are on the verge of answering one of our most profound questions: are we alone in the universe? The ability to detect life in remote solar systems is at last within sight, and its discovery—even if only in microbial form—would revolutionize our self-image. Planet Hunters is the rollicking tale of the search for extraterrestrial life and the history of an academic discipline. Astronomer Lucas Ellerbroek takes readers on a fantastic voyage through space, time, history, and even to the future as he describes the field of exoplanet research, from the early ideas of sixteenth-century heretic Giordano Bruno to the discovery of the first exoplanet in 1995 to the invention of the Kep...
In the vein of acclaimed popular-science bestsellers such as Atlas Obscura, Astrophysics for Young People in a Hurry, The Way Things Work, What If?, and Undeniable, the co-founders of the global science organization Nerd Nite bring readers a collection of wacky, yet fascinating STEM topics. For 20 years, Nerd Nite has delivered to live audiences around the world, the most interesting, fun, and informative presentations about science, history, the arts, pop culture, you name it. There hasn’t been a rabbit hole that their army of presenters hasn’t been afraid to explore. Finally, after countless requests to bring Nerd Nite to more fans across the globe, co-founders and college pals Matt Wa...
"A harrowing account of the profoundly consequential decisions American universities made about refugee scholars from Nazi-dominated Europe. The United States' role in saving Europe's intellectual elite from the Nazis is often told as a tale of triumph, which in many ways it was. America welcomed Albert Einstein and Enrico Fermi, Hannah Arendt and Herbert Marcuse, Rudolf Carnap and Richard Courant, among hundreds of other physicists, philosophers, mathematicians, historians, chemists, and linguists who transformed the American academy. Yet for every scholar who survived and thrived, many, many more did not. To be hired by an American university, a refugee scholar had to be world-class and well connected, not too old and not too young, not too right and not too left and, most important, not too Jewish. Those who were unable to flee were left to face the horrors of the Holocaust. In this rigorously researched book, Laurel Leff rescues from obscurity scholars who were deemed "not worth saving" and tells the riveting, full story of the hiring decisions universities made during the Nazi era."--Provided by publisher.
Met goed onderwijs zijn grote belangen gediend. Niet verwonderlijk dus dat politici, bestuurders en belangenbehartigers het onderwijs willen beheersen en veranderen. Zij richten zich daarbij met name op leraren, die daardoor steeds minder ruimte ervaren om een wezenlijke bijdrage te kunnen leveren aan de essentie van onderwijs: het voortdurende scheppings- en wordingsproces van ieder kind en de wereld. De pedagogische relatie tussen leraar en leerling komt zo steeds meer onder druk te staan. Het gebrek aan professionele ruimte en het gevoel in de pedagogische relatie tekort te schieten, begint steeds meer mensen in het onderwijs te beknellen. Zij zijn de bestuurlijke drukte en de stapeling v...
Una guía sobre una apasionante materia científica, que muestra que los signos que revelan que hay vida en la Tierra pueden ser la clave para detectarla también fuera de nuestro planeta. Un análisis de los numerosos planetas que han descubierto las misiones Kepler y TESS de la NASA fuera del Sistema Solar. Incluye detalles cruciales sobre la búsqueda de vida extraterrestre, como la paradoja de Fermi, la ecuación de Drake y la señal "Wow!". La posibilidad de que exista vida extraterrestre es una de las conjeturas más trascendentales de la humanidad. Hoy en día se indaga en este campo no solo desde la literatura de ciencia ficción, sino también desde la investigación en el ámbito de la ciencia. Puesto que en Marte ya hay todoterrenos de la NASA y otras sondas escudriñan lugares más lejanos del cosmos, esta edición ilustrada combina infografías con imágenes del espacio profundo para ofrecer una visión bien informada sobre las búsquedas científicas más significativas.
“How do alien, faraway worlds reveal their existence to Earthlings? Let Donald Goldsmith count the ways. As an experienced astronomer and a gifted storyteller, he is the perfect person to chronicle the ongoing hunt for planets of other stars.” —Dava Sobel Astronomers have recently discovered thousands of planets that orbit stars throughout our Milky Way galaxy. With his characteristic wit and style, Donald Goldsmith presents the science of exoplanets and the search for extraterrestrial life in a way that Earthlings with little background in astronomy or astrophysics can understand and enjoy. Much of what has captured the imagination of planetary scientists and the public is the unexpec...
