Richard Gott take readers on an unforgettable journey of exploration to reveal how our universe actually works.Propelling you from our home solar system to the outermost frontiers of space, this book builds your cosmic insight and perspective through a marvelously entertaining narrative. How do stars live and die? What are the prospects of intelligent life elsewhere in the universe? How did the universe begin? Why is it expanding and accelerating? Is our universe alone or part of an infinite multiverse? Exploring these and many other questions, this pocket-friendly book is your passport into the wonders of our evolving cosmos.

    In this compelling, accessible, and elegantly reasoned new book, award-winning scholar and researcher Chris Impey explores the foundations of this rapidly developing discipline, where it’s going, and what it’s likely to find. The journey begins with the earliest steps of science, gaining traction through the revelations of the Renaissance, including Copernicus’s revolutionary declaration that the Earth was not the center of the universe but simply a planet circling the sun. But if Earth is not the only planet, it is so far the only living one that we know of. In fascinating detail, The Living Cosmos reveals the incredible proliferation and variety of life on Earth, paying special tribute to some of its hardiest life forms, extremophiles, a dizzying array of microscopic organisms compared, in Impey’s wise and humorous prose, to superheroes that can survive extreme heat and cold, live deep within rocks, or thrive in pure acid.From there, Impey launches into space, where astrobiologists investigate the potential for life beyond our own world. Is it to be found on Mars, the “death planet” that has foiled most planetary missions, and which was wet and temperate billions of years ago? Or on Venus, Earth’s “evil twin,” where it rains sulfuric acid and whose heat could melt lead? (“Whoever named it after the goddess of love had a sorry history of relationships.”) The answer may lie in a moon within our Solar System, or it may be found in one of the hundreds of extra-solar planets that have already been located. The Living Cosmos sees beyond these explorations, and imagines space vehicles that eschew fuel for solar- or even nuclear-powered rockets, all sent by countries motivated by the millions to be made in space tourism.But The Living Cosmos is more than just a riveting work about experiment and discovery. It is also an affecting portrait of the individuals who have devoted their lives to astrobiology. Illustrated throughout, The Living Cosmos is a revelatory book about a science that is changing our view of the universe, a mesmerizing guide to what life actually means and where it may–or may not–exist, and a stunning work that explains our past as it predicts our future.

    Before the decade is out, telltale signs that they harbor life may be found. If they are, the ramifications for all areas of human thought and endeavor--from religion and philosophy to art and biology--will be breathtaking. In Strange New Worlds, renowned astronomer Ray Jayawardhana brings news from the front lines of the epic quest to find planets--and alien life--beyond our solar system.Only in the past fifteen years, after millennia of speculation, have astronomers begun to discover planets around other stars--hundreds in fact. But the hunt to find a true Earth-like world goes on. In this book, Jayawardhana vividly recounts the stories of the scientists and the remarkable breakthroughs that have ushered in this extraordinary age of exploration. He describes the latest findings--including his own--that are challenging our view of the cosmos and casting new light on the origins and evolution of planets and planetary systems. He reveals how technology is rapidly advancing to support direct observations of Jupiter-like gas giants and super-Earths--rocky planets with several times the mass of our own planet--and how astronomers use biomarkers to seek possible life on other worlds.Strange New Worlds provides an insider's look at the cutting-edge science of today's planet hunters, our prospects for discovering alien life, and the debates and controversies at the forefront of extrasolar-planet research.

    Right?! Machine Learning is a branch of computer science that wants to stop programming computers using a detailed list of commands to follow blindly. Instead, their aim is to implement high-level routines that teach computers how to approach new and unknown problems – these are called algorithms. In practice, they want to give computers the ability to Learn and to Adapt. We can use these algorithms to obtain insights, recognize patterns and make predictions from data, images, sounds or videos we have never seen before – or even knew existed. Unfortunately, the true power and applications of today’s Machine Learning Algorithms remain deeply misunderstood by most people. Through this book I want fix this confusion, I want to shed light on the most relevant Machine Learning Algorithms used in the industry. I will show you exactly how each algorithm works, why it works and when you should use it.

    A number of the key figures in the new edition are revised to provide a more inviting and informative treatment. The figures are broken into component parts with supporting commentary so that they can more readily see the key ideas. Material from The Flying Circus is incorporated into the chapter opener puzzlers, sample problems, examples and end-of-chapter problems to make the subject more engaging. Checkpoints enable them to check their understanding of a question with some reasoning based on the narrative or sample problem they just read. Sample Problems also demonstrate how engineers can solve problems with reasoned solutions.

    Half a century later, only robots have been to the Red Planet and our astronauts rarely venture beyond Earth orbit.Now Mars is back With everyone from Elon Musk to Ridley Scott and Donald Trump talking about it, interplanetary exploration is back on the agenda and Mars is once again the prime destination for future human expansion and colonisation. In Destination Mars, astrophysicist and science writer Andrew May traces the history of our fascination with the Red Planet and explores the science upon which a crewed mission would be based, from assembling a spacecraft in Earth orbit to surviving solar storms. With expert insight, he analyses the new space race and assesses what the future holds for human life on Mars.

    Surprisingly, a great many players surveyed did not even know you need to hit down to get the ball up in the air. Hit Down @#!*% ! concisely explains the concept - and the technique - of hitting down at the golf ball for proper trajectory, increased backspin, much improved distance, proper divot taking, and best of all: consistent shotmaking.If you are inadvertently - or intentionally - hitting up at the ball, Hit Down @#!*% ! is for you. (Also available as DVD series, and MP3 download, all on Amazon.)If you are a seasoned amateur who has inexplicably “plateaud” - just cannot seem to get to the next level despite lessons and/or acquiring a library of books and videos - Hit Down @#!*% ! is for you.Symptoms of hitting up include (but are not limited to): - topping the ball- skulling the ball- pushing the ball- slicing the ball- poor distance- difficulty getting off back foot- poor backspin- no divot- fat divots- chunking the ball- thin/fat chip shots- roofing the ball with your driver- inability to hit long irons and/or fairway woods- good shots followed immediately by poor shotsHitting down at the golf ball is not a new concept, but it is a hitherto poorly explained (or completely avoided) concept. All pros agree on the need to hit down, so there is no debate there. Even Tiger Woods, in his 306 page “How I Play Golf”, states the need to hit down at the ball – but does not explain how. Hit Down @#!*% ! does. Learn to hit down, watch the ball go up, and your scores go down. BONUS: At the end of this book you will find a link to purchase the Hit Down @#!*% ! 4 DVD series and receive a full credit for the purchase of this Kindle ebook.

    

    The theory is sound, but something goes wrong, and a highly contagious combination of virus and prion is unleashed, a middle-stage organism too dangerous to test. With emergency services overwhelmed, a small community hospital tries to combat the unthinkable--an illness that causes aggression, spreads through violence, and won’t allow the dead to rest.

    Whatever your circumstances, you can create the life you desire by following simple, counterintuitive steps; not the steps society wants you to follow. Unfortunately, you cannot even trust yourself when it comes to creating the life that you desire, because you’re programmed by your past, an accumulation of hundreds of thousands of years, a mind still adapted for a hunter-gatherer time period. What does this mean? It means every day you’re battling your emotions, logic versus emotion. Logically, you want to do one thing, but emotionally, you are drawn to something else. First, if this sounds familiar, then great, because it means you are human. But, if you’re going to win the game of life, you cannot sit around and wait for things to happen, because you’ll be living a life of supreme comfort and sameness; ultimately, a great sin. You are destined for great things, capable of forging dreams and living your aspirations. Maybe you’ve forgotten about this truth: that you are capable, worthy, and ready. Maybe you’ve been beaten into the ground by life, a teacher who doesn’t care if you’re rich or poor, weak or strong, ready or not, because life will continue forward regardless, waiting for no one. Fortunately, there’re things you can do to set yourself apart from the millions that will ultimately suffer and fail. One such thing, perhaps the most powerful of all, is by studying the great, people who have succeeded and who have gone beyond what is humanly thought possible. When it comes to studying someone great, there’s one name that stands tall, Stephen Hawking, a person who has persevered and flourished. Not only has he conquered great adversity, but he has inspired millions around the world with his brilliant mind. There is a reason why people compare him with the once living Albert Einstein, the genius. What follows are Stephen Hawking’s greatest life lessons, gems of wisdom that you can easily apply to your own life, which will help you live a more abundant, stronger life. If you’re in need of inspiration, a boost of confidence, or just a friendly reminder of the wonders in life, you’ve come to the right place. See for yourself why millions study his work and regard him as a genius. Scroll up and grab your copy today.*** Limited time offer ***

    The book is designed for advanced undergraduates or beginning graduate students and assumes no prior knowledge of general relativity. An emphasis is placed on developing the readers' physical insight rather than losing them with complex math. An approachable writing style and wealth of fresh and imaginative analogies from "everyday" physics are used to make the concepts of cosmology more accessible. The book is unique in that it not only includes recent major developments in cosmology, like the cosmological constant and accelerating universe, but also anticipates key developments expected in the next few years, such as detailed results on the cosmic microwave background.

    It has been developed specifically for emerging courses in astrobiology, though it can also be used for introductory astronomy.

    All three astronauts were experienced pilots and had dreams of one day walking on the moon, but little did they know, nor did anyone else, that once they entered the spacecraft that cold winter day they would never leave it alive. The Apollo program would be perilously close to failure before it ever got off the ground. But rather than dooming the space program, this tragedy caused the spacecraft to be completely overhauled, creating a stellar flying machine to achieve the program’s primary goal: putting man on the moon. Apollo 1 is a candid portrayal of the astronauts, the disaster that killed them, and its aftermath. In it, readers will learn: How the Apollo 1 spacecraft was doomed from the start, with miles of uninsulated wiring and tons of flammable materials in a pure oxygen atmosphere, along with a hatch that wouldn’t open How, due to political pressure, the government contract to build the Apollo 1 craft went to a bidder with an inferior plan How public opinion polls were beginning to turn against the space control before the tragedy and got much worse after Apollo 1 is about America fulfilling its destiny of man setting foot on the moon. It’s also about the three American heroes who lost their lives in the tragedy, but whose lives were not lost in vain.
