Astronomi og univers

Universet er på én gang vores hjem og en verden af enormt komplekse begreber. Så hvordan skal alle vi, der ikke har en grad i fysik, forstå det? Den berømte amerikanske astrofysiker Neil deGrasse Tysons lille, charmerende bog Astrofysik for travle mennesker er skrevet, så du og jeg kan få en fornemmelse af vores vilde og smukke hjem, mens vi venter på bussen eller morgenkaffen brygger færdig. Her er alle de vigtigste idéer og opdagelser, der ligger til grund for vores moderne forståelse af universet, serveret med liv, vid og en humoristisk pen. Fra Big Bang til sorte huller, fra kvarker til kvantemekanik og mørkt stof og jagten på at opdage exoplaneter og finde andet liv i universet. Neil deGrasse Tyson er en stor formidler, der ikke alene kan forklare astrofysik, så vi alle kan forstå det, men også formår at sætte videnskaben ind i et større perspektiv – og give stof til undren og eftertanke. Han opfordrer os til så ofte som muligt at træde ud, læne nakken tilbage og kigge op i nattehimlen. Fortabe os i, hvor storslået vores univers er og sætte livet og kloden i et kosmisk perspektiv. Astrofysik for travle mennesker er grundlæggende godt selskab – og efterlader en både klogere, mere nysgerrig og fuld af forundring.

The fantastic first book in the Sunday Times bestselling Science of Discworld seriesWhen a wizardly experiment goes adrift, the wizards of Unseen University find themselves with a pocket universe on their hands: Roundworld, where neither magic nor common sense seems to stand a chance against logic. The Universe, of course, is our own. And Roundworld is Earth. As the wizards watch their accidental creation grow, we follow the story of our universe from the primal singularity of the Big Bang to the internet and beyond. Through this original Terry Pratchett story (with intervening chapters from Cohen and Stewart) we discover how puny and insignificant individual lives are against a cosmic backdrop of creation and disaster. Yet, paradoxically, we see how the richness of a universe based on rules, has led to a complex world and at least one species that tried to get a grip of what was going on. Terry Pratchett is the acclaimed creator of the global bestselling Discworld series, the first of which, The Colour of Magic, was published in 1983. Raising Steam is his fortieth Discworld novel. His books have been widely adapted for stage and screen, and he is the winner of multiple prizes, including the Carnegie Medal, as well as being awarded a knighthood for services to literature. After falling out with his keyboard he now talks to his computer. Occasionally, these days, it answers back.www.terrypratchett.co.uk@terryandrob Professor Ian Stewart is the author of many popular science books. He is the mathematics consultant for New Scientist and a Professor of Mathematics at the University of Warwick. He was awarded the Michael Faraday Prize for furthering the public understanding of science, and in 2001 became a Fellow of the Royal Society. Dr Jack Cohen is an internationally-known reproductive biologist, and lives in Newent, Gloucestershire. Jack has a laboratory in his kitchen, helps couples get pregnant by referring them to colleagues, invents biologically realistic aliens for science fiction writers and, in his spare time, throws boomerangs. Jack, who has more letters to his name than can be repeated here, writes, lectures, talks and campaigns to promote public awareness of science, particularly biology. He is mostly retired.

With over 100,000 copies sold since first publication, this is one of the most popular astronomy books of all time. It is a unique guidebook to the night sky, providing all the information you need to observe a whole host of celestial objects. With a new spiral binding, this edition is even easier to use outdoors at the telescope and is the ideal beginner's book. Keeping its distinct one-object-per-spread format, this edition is also designed for Dobsonian telescopes, as well as for smaller reflectors and refractors, and covers Southern hemisphere objects in more detail. Large-format eyepiece views, positioned side-by-side, show objects exactly as they are seen through a telescope, and with improved directions, updated tables of astronomical information and an expanded night-by-night Moon section, it has never been easier to explore the night sky on your own. Many additional resources are available on the accompanying website, www.cambridge.org/turnleft.

Teorien om Big Bang er den bedste model, vi i øjeblikket har om universets skabelse; men det betyder ikke, at det er den endelige sandhed. Men hvorfor er der stort set enighed om, at universet for 13,7 milliarder år siden blev skabt af en tætpakket klump, der rummede al energi og alt stof? Og eksisterede der noget inden Big Bang? Astrofysikeren Anja C. Andersen formidler teorier og forskningsresultater udogmatisk og letforståeligt.

Recommended for viewing on a colour tablet.Professor Brian Cox is back with another insightful and mind-blowing exploration of space. This time he shows us our universe as we've never seen it before.13.7 billion years old. 93 billion light years wide. It contains over 100 billion galaxies, each containing hundreds of billions of stars. This infinite, vast and complex Universe has been the subject of human fascination and scientific exploration for thousands of years. The wonders of the Universe might seem alien to us and impossible to understand, but away from the telescopes, the labs and the white coats, Professor Brian Cox uses the evidence found in the natural world around us to explain its simple truths.The same laws of light, gravity, time, matter and energy that govern us here on Earth are the same as those applied in the Universe. Using his expert knowledge and his infectious enthusiasm, Professor Cox shows us that if we can understand the impact of these governing laws on Earth it will bring us a step closer to an understanding of our Universe.

What is time? The 5th-century philosopher St Augustine famously said that he knew what time was, so long as no one asked him. Is time a fourth dimension similar to space or does it flow in some sense? And if it flows, does it make sense to say how fast? Does the future exist? Is time travel possible? Why does time seem to pass in only one direction?These questions and others are among the deepest and most subtle that one can ask, but "e;Introducing Time"e; presents them - many for the first time - in an easily accessible, lucid and engaging manner, wittily illustrated by Ralph Edney.
