Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

    More than a possibility, it is becoming a necessity: whether our hand is forced by climate change and resource depletion or whether future catastrophes compel us to abandon Earth, one day we will make our homes among the stars.World-renowned physicist and futurist Michio Kaku explores in rich, accessible detail how humanity might gradually develop a sustainable civilization in outer space. With his trademark storytelling verve, Kaku shows us how science fiction is becoming reality: mind-boggling developments in robotics, nanotechnology, and biotechnology could enable us to build habitable cities on Mars; nearby stars might be reached by microscopic spaceships sailing through space on laser beams; and technology might one day allow us to transcend our physical bodies entirely.With irrepressible enthusiasm and wonder, Dr. Kaku takes readers on a fascinating journey to a future in which humanity could finally fulfil its long-awaited destiny among the stars - and perhaps even achieve immortality.

    Yuri Gagarin is one of the great heroes of the twentieth century, but the details of his life and the Russian space effort have been shrouded in secrecy: even the names of the engineers who worked with Gagarin were a mystery to the West for many years.Starman is the first book to tell the compelling story behind Gagarin's life and his audacious first flight into space aboard a converted nuclear weapon.He was once the most famous man in the world yet in his life, as in death, he was a man the world knew almost nothing about.

    

    Unlike the rest of the world's archipelagoes, it still has 95 percent of its prehuman quota of species. Wildlife of the Galapagos is the most superbly illustrated and comprehensive identification guide ever to the natural splendor of these incomparable islands--islands today threatened by alien species and diseases that have diminished but not destroyed what so enchanted Darwin on his arrival there in 1835. Covering over 200 commonly seen birds, mammals, reptiles, invertebrates, and plants, it reveals the archipelago's striking beauty through more than 400 color photographs, maps, and drawings and well-written, informative text. While the Galapagos Giant Tortoise, the Galapagos Sea Lion, and the Flightless Cormorant are recognized the world over, these thirty-three islands--in the Pacific over 600 miles from mainland Ecuador--are home to many more unique but less famous species. Here, reptiles well outnumber mammals, for they were much better at drifting far from a continent the archipelago was never connected with; the largest native land mammals are rice rats. The islands' sixty resident bird species include the only penguin to breed entirely in the tropics and to inhabit the Northern Hemisphere. There is a section offering tips on photography in the Equatorial sunlight, and maps of visitors' sites as well as information on the archipelago's history, climate, geology, and conservation. Wildlife of the Galapagos is the perfect companion for anyone who wants to know what so delighted Darwin. Covers over 200 commonly seen species including birds, mammals, reptiles, invertebrates, plants, and coastal and marine life Illustrated with over 400 color photographs, maps, and drawings; includes maps of visitors' sites Written by wildlife experts with extensive knowledge of the area Includes information on the history, climate, geology, and conservation of the islands The most complete identification guide to the wildlife of the Galapagos

    Every massive star leaves behind a black hole when it dies, and every galaxy harbors a supermassive black hole at its center. Frighteningly enigmatic, these dark giants continue to astound even the scientists who spend their careers studying them. Which came first, the galaxy or its central black hole? What happens if you travel into one—instant death or something weirder? And, perhaps most important, how can we ever know anything for sure about black holes when they destroy information by their very nature?In Einstein’s Monsters, distinguished astronomer Chris Impey takes readers on an exploration of these and other questions at the cutting edge of astrophysics, as well as the history of black holes’ role in theoretical physics—from confirming Einstein’s equations for general relativity to testing string theory. He blends this history with a poignant account of the phenomena scientists have witnessed while observing black holes: stars swarming like bees around the center of our galaxy; black holes performing gravitational waltzes with visible stars; the cymbal clash of two black holes colliding, releasing ripples in space-time.Clear, compelling, and profound, Einstein’s Monsters reveals how our comprehension of black holes is intrinsically linked to how we make sense of the universe and our place within it. From the small questions to the big ones—from the tiniest particles to the nature of space-time itself—black holes might be the key to a deeper understanding of the cosmos.

    Decades ago, astronauts brought back 850 pounds of rocks from their lunar journeys; the U.S. gave some away as “goodwill” gifts to the world’s nations. Over time, many of them disappeared, stolen or lost in the aftermath of political turmoil, and offered for millions on the black market. Gutheinz, first as a NASA investigator and then the leader of a intrepid group of students, has dedicated his life to getting them back. Author Joe Kloc tells a wild story of geopolitics, crime, science, and one man’s obsession with keeping the moon out of the wrong hands.

    As a young navy pilot, Alan wished he could paint the view from the cockpit. So he took an art class to learn patterns and forms. But no class could prepare him for the beauty of the lunar surface some 240,000 miles from Earth. In 1969, Alan became the fourth man and first artist on the moon. He took dozens of pictures, but none compared to what he saw through his artistic eyes. When he returned to Earth, he began to paint what he saw. Alan's paintings allowed humanity to experience what it truly felt like to walk on the moon. Journalist and storyteller Dean Robbins's tale of this extraordinary astronaut is masterful, and artist Sean Rubin's illustrations are whimsical and unexpected. With back matter that includes photos of the NASA mission, images of Alan's paintings, and a timeline of lunar space travel, this is one adventure readers won't want to miss!
