In the coming years, we will make decisions regarding our human spaceflight program that will lead to one of two familiar futures: the open universe of "Star Trek, "where we allow ourselves the opportunity to spread our wings and attempt to flourish as an interplanetary species--or the closed, dystopian, and ultimately self-destructive world of "Soylent Green." If we ever hope to live in the future that is the former scenario, our first stepping stone must be a manned mission to Mars. In this four-part e-special, Dr. Robert Zubrin details the challenges of a manned Earth-to-Mars mission. Challenges which, according to Zubrin, we are technologically more prepared to overcome than the obstacles of the missions to the moon of the sixties and seventies. Dr. Zubrin's relatively simple plan, called Mars Direct, could feasibly have humans on the surface of Mars within a decade. Zubrin also discusses the current predicament of NASA, the promise of privatized space flight from companies like SpaceX, and the larger implication behind the absolute necessity to open the final frontier to humanity--the human race's future as a species that takes the necessary baby steps away from the cradle that is planet Earth or, ultimately, perishes here.

    With clear explanations of some of the most complex scientific endeavors in history, Mahaffey's new book looks back at the atom's wild, secretive past and then toward its potentially bright future.Mahaffey unearths lost reactors on far flung Pacific islands and trees that were exposed to active fission that changed gender or bloomed in the dead of winter. He explains why we have nuclear submarines but not nuclear aircraft and why cold fusion doesn't exist. And who knew that radiation counting was once a fashionable trend? Though parts of the nuclear history might seem like a fiction mash-up, where cowboys somehow got a hold of a reactor, Mahaffey's vivid prose holds the reader in thrall of the infectious energy of scientific curiosity and ingenuity that may one day hold the key to solving our energy crisis or sending us to Mars.

    In the late 1920s, astronomers defeated this assumption with a startling new discovery. From Earth, the light of distant galaxies appeared to be red, meaning that those galaxies were receding from us. This led to the revolutionary realization that the universe is expanding. The Red Limit is the tale of this discovery, its ramifications, and the passionately competitive astronomers who charted the past, present, and future of the cosmos.

    “A marvelously readable and level-headed explanation of basic science and how it relates to the issues.” —John Tierney, New York TimesThis is “must-have” information for all presidents—and citizens—of the twenty-first century: Is Iran’s nascent nuclear capability a genuine threat to the West? Are biochemical weapons likely to be developed by terrorists? Are there viable alternatives to fossil fuels that should be nurtured and supported by the government? Should nuclear power be encouraged? Can global warming be stopped?

    Nothing you experience would be possible without the intricate power of your senses. But how much about them do you really know?Your ability to sense and perceive the world around you is so richly detailed and accurate as to be miraculous. No tool in the entire universe of scientific exploration can come close to matching the ability of your brain to use information sensed by your eyes, ears, skin, tongue, and nose to produce a rich sensory experience in just milliseconds.In recent years, neurobiologists and other scientists have uncovered new insights into how your senses work and the amazingly complex and fascinating things they can do. And now you can share in what they've discovered-through this intriguing series of 24 lectures from an award-winning teacher.Knowing how your senses work and the ways they shape how you see, interact with, and understand your life will help you think more critically about everything you sense and perceive, strengthen your appreciation of the senses that make this possible, prepare you to be an active consumer of new scientific evidence on how our senses work, and much more.With Professor Vishton as your guide, you'll. consider each of your senses from multiple perspectives:Explore how your brain processes different sensory informationConsider how your senses work together and within the context of the environment around youdiscover how your senses connect you to the world and other people.Using both cutting-edge research and simple experiments, tests, and demonstrations to hone your understanding, he has created a world-class learning experience that will change the way you think about your senses.

    Plait created his popular web site: http://www.badastronomy.com/index.html, to debunk bad astronomy in popular culture. This website proved popular, which led to this first book by Plait, that carries on from the website and in a detailed and clear fashion criticises and disproves popular myths and misconceptions relating to astronomy, and promotes science as a means of explaining the skies. The work describes 24 common astronomical fallacies, including the beliefs that the Coriolis effect determines the direction that water drains in a bathtub, and that planetary alignments can cause disaster on Earth. The author sharply and convincingly dismisses astrology, creationism, and UFO sightings, and explains the principles behind basic general concepts (the Big Bang, why the sky is blue, etc.).

    Growing up in a working-class Long Island family, Massimino catapulted himself to Columbia and then MIT, only to flunk his qualifying exams and be rejected twice by NASA before making it to the final round of astronaut selection—where he was told his poor eyesight meant he’d never make the cut. But even that couldn’t stop him from finally earning his wings, making the jump to training in T-38 Air Force jets and preparing his body—and soul—for the journey to the cosmos.Taking us through the surreal wonder and beauty of his first spacewalk, the tragedy of losing friends in the Columbia shuttle accident, and the development of his enduring love for the Hubble telescope—which he’d be tasked with saving on his final mission— Massimino has written an ode to never giving up and the power of teamwork to make anything possible. Spaceman invites us into a rare, wonderful world where the nerdiest science meets the most thrilling adventure, and pulls back a curtain on just what having “the right stuff” really means.

    In 24 enthralling lectures, Professor Miller guides you through a core selection of the major books of the Old Testament, inviting you to probe their meaning and relevance in incisive and thought-provoking commentary. Among the books of the Old Testament, you’ll explore:• Genesis: Uncover fascinating features of the Old Testament’s opening, such as how the events of the first week of creation form an elaborate pattern, expressing the complex order of the universe; and how the text does not lay primary blame for “the fall” on the woman, Eve;• Deuteronomistic History: Study the epic history of the people of Israel in the Promised Land; follow the story of the Israelites’ disobedience to God, and its tragic consequences; • The Prophets: Through the dramatic stories of the prophets, take account of the challenges faced by those who sought to actualize God’s plan for humanity; • The Books of Ruth and Esther: Among notable women in the Old Testament, explore two stories of women who are doubly at risk, and who prevail through loyalty, resourcefulness, and integrity; and• Daniel and the Apocalyptic: In the Book of Daniel, encounter the genre of apocalyptic literature - revelation initiated by God - and contemplate the figure of “the Son of Man,” a promised redeemer.Throughout the lectures, Professor Miller offers a wealth of perspectives on how to approach the texts. You’ll assess the role of translation in the understanding of the texts, studying the meanings of key Hebrew words; you’ll also look in depth at the history, dating, and writing of the texts, and you’ll study their literary and linguistic features, noting how they achieve their impact on the reader.In Understanding the Old Testament, you’ll take a revelatory look at this epically impactful document, finding its deeper historical and religious meanings, as well as its sublime literary treasures.

    In the 14 billion years since, scientists have pointed their telescopes upward, peering outward in space and backward in time, developing and refining theories to explain the weird and wonderful phenomena they observed.Through these observations, we now understand concepts like the size of the universe (still expanding), the distance to the next-nearest star from earth (Alpha Centauri, 26 trillion miles) and what drives the formation of elements (nuclear fusion), planets and galaxies (gravity), and black holes (gravitational collapse). But are these cosmological questions definitively answered or is there more to discover?Oxford University astrophysicist and popular YouTube personality Dr. Becky Smethurst presents everything you need to know about the universe in 10 accessible and engaging lessons.In Space at the Speed of Light: The History of 14 Billion Years for People Short on Time, she guides you through fundamental questions, both answered and unanswered, posed by space scientists. Why does gravity matter? How do we know the big bang happened? What is dark matter? Do aliens exist? Why is the sky dark at night? If you have ever looked up at night and wondered how it all works, you will find answers - and many more questions - in this pocket-sized tour of the universe!

    But almost everything about it, from the elements that forged stars, planets, and lifeforms, to the fundamental forces of physics, can be traced back to what happened in just the first three minutes of its life.In this book, Nobel Laureate Steven Weinberg describes in wonderful detail what happened in these first three minutes. It is an exhilarating journey that begins with the Planck Epoch - the earliest period of time in the history of the universe - and goes through Einstein's Theory of Relativity, the Hubble Red Shift, and the detection of the Cosmic Microwave Background. These incredible discoveries all form the foundation for what we now understand as the "standard model" of the origin of the universe. The First Three Minutes examines not only what this model looks like, but also tells the exciting story of the bold thinkers who put it together.Clearly and accessibly written, The First Three Minutes is a modern-day classic, an unsurpassed explanation of where it is we really come from.

    Filled with surprising stories of accidental genius and brilliant mistakes—from the French publisher who invented the phonograph before Edison but forgot to include playback, to the Hollywood movie star who helped invent the technology behind Wi-Fi and Bluetooth—How We Got to Now investigates the secret history behind the everyday objects of contemporary life. In his trademark style, Johnson examines unexpected connections between seemingly unrelated fields: how the invention of air-conditioning enabled the largest migration of human beings in the history of the species—to cities such as Dubai or Phoenix, which would otherwise be virtually uninhabitable; how pendulum clocks helped trigger the industrial revolution; and how clean water made it possible to manufacture computer chips. Accompanied by a major six-part television series on PBS, How We Got to Now is the story of collaborative networks building the modern world, written in the provocative, informative, and engaging style that has earned Johnson fans around the globe.

    In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard’s top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization.   In Extraterrestrial, Loeb takes readers inside the thrilling story of the first interstellar visitor to be spotted in our solar system. He outlines his controversial theory and its profound implications: for science, for religion, and for the future of our species and our planet. A mind-bending journey through the furthest reaches of science, space-time, and the human imagination, Extraterrestrial challenges readers to aim for the stars—and to think critically about what’s out there, no matter how strange it seems.

    Supernatural magic is what our ancestors used in order to explain the world before they developed the scientific method. The ancient Egyptians explained the night by suggesting the goddess Nut swallowed the sun. The Vikings believed a rainbow was the gods’ bridge to earth. The Japanese used to explain earthquakes by conjuring a gigantic catfish that carried the world on its back—earthquakes occurred each time it flipped its tail. These are magical, extraordinary tales. But there is another kind of magic, and it lies in the exhilaration of discovering the real answers to these questions. It is the magic of reality—science.Packed with clever thought experiments, dazzling illustrations and jaw-dropping facts, The Magic of Reality explains a stunningly wide range of natural phenomena. What is stuff made of? How old is the universe? Why do the continents look like disconnected pieces of a puzzle? What causes tsunamis? Why are there so many kinds of plants and animals? Who was the first man, or woman? This is a page-turning, graphic detective story that not only mines all the sciences for its clues but primes the reader to think like a scientist as well.Richard Dawkins, the world’s most famous evolutionary biologist and one of science education’s most passionate advocates, has spent his career elucidating the wonders of science for adult readers. But now, in a dramatic departure, he has teamed up with acclaimed artist Dave McKean and used his unrivaled explanatory powers to share the magic of science with readers of all ages. This is a treasure trove for anyone who has ever wondered how the world works. Dawkins and McKean have created an illustrated guide to the secrets of our world—and the universe beyond—that will entertain and inform for years to come.
