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.

    QFT is the only physics theory that makes sense and that dispels or resolves the paradoxes of relativity and quantum mechanics that have confused and mystified so many people.

    G. Wells' 1895 classic The Time Machine, readers of science fiction have puzzled over the paradoxes of time travel. What would happen if a time traveler tried to change history? Would some force or law of nature prevent him? Or would his action produce a "new" history, branching away from the original?In the last decade of the twentieth century a group of theoretical physicists at the California Institute of Technology undertook a serious investigation of the possibility of pastward time travel, inspiring a serious and sustained study that engaged more than thirty physicists working at universities and institutes around the world.Many of the figures involved are familiar: Einstein, Stephen Hawking and Kip Thorne; others are names known mostly to physicists. These are the new time travelers, and this is the story of their work--a profoundly human endeavor marked by advances, retreats, and no small share of surprises. It is a fantastic journey to the frontiers of physics.

    In this thrill-ride across millennia and continents, the complete history of the planet comes to life: from the Earth's fiery birth to its near-obliteration in the Triassic period, and from the first signs of human life to the tentative future of a world with a burgeoning population and a global warming crisis. Covering a wide range of topics including astrophysics, zoology, and sociology, and complete with maps and illustrations, What on Earth Happened? In Brief is the endlessly entertaining story of the planet, life, and people.

    Traveling to a tropical island with the mysterious "Tribe of Millionaires," Ethan finds his whole approach to business and life shifting with each lesson.The more time Ethan spends with the enigmatic members of the tribe, the more he comes to realize that the answers he seeks are, as they are for all of us, hidden in plain sight.

     There are only men, and their kings and queens, and some such rulers are always looking for trouble. In the brutal north, thieves Maskan and Sand know the king Morag’s justice is uncommonly harsh, while his politics seem to drive a wedge between allies and granting opportunities for their enemies. The man is, in short, rumored to be mad, and one of those kings who find trouble. Such politics and kings are no concern of theirs, until they pickpocket the wrong victim, and get caught in the aforementioned politics, and tangled with the harsh law of Morag. In the end, both thieves find themselves allied with noble families, whose motives are shady, and perhaps, also, they find the world is not made only for men, and the king is not as mad as rumoured. Something has crept into Midgard. The Beast of the North is a book one in bestselling, savage story of the Nine Worlds, a Norse Mythology inspired epic, dark fantasy adventure.

    The book emphasizes a general introduction to probability theory and provides a detailed discussion of specific designs and analyses that are typically encountered in ecology and environmental science. Appropriate for use as either a stand-alone or supplementary text for upper-division undergraduate or graduate courses in ecological and environmental statistics, ecology, environmental science, environmental studies, or experimental design, the Primer also serves as a resource for environmental professionals who need to use and interpret statistics daily but have little or no formal training in the subject.

    They have learned and integrated systematic thinking into their own mental toolbox. They can leverage these models to produce better than average results. A mental model is just a simplified way of looking at a more complex problem. It allows you to more easily understand and reach an accurate conclusion. You may not be aware, but you use models every day. A map is an example of a model that most people understand. When you leave your house to go to work you don’t need to constantly consult written directions, you have internalized the map. You have a mental model of how to get to work. This saves you time and simplifies your life. Now imagine being able to internalize mental models for different and more complex types of problems. Author, Kevin Wagonfoot, covers 30 mental models that you can use to improve any facet of your life. The book is broken down into eight chapters, each containing several relevant models. Chapters include: Decision Making Dealing With Others Understanding Creativity Reasoning Negotiating Learning Working While there are literally thousands of different mental models out there, this book serves as a guide to understanding some of the most basic and broadly applied models. If you have ever wanted to streamline your thought process, increase your mental horsepower, or just simplify your life... Buy this Book Today!

    For the calculus-based General Physics course primarily taken by engineers and scientists.

    David Peat explains the development and meaning of this Superstring Theory in a thoroughly readable, dramatic manner accessible to lay readers with no knowledge of mathematics. The consequences of the Superstring Theory are nothing less than astonishing.

    Damage to a Russian aircraft carrier leads to a breakdown in the detente with the United States. Star wars erupt as the two countries invoke space-based weapons in a deadly face off in orbit. Robert Issacs, Deputy Director of Scientific Intelligence for the CIA, and his top aide, Dr. Patricia Danielson, connect the carrier damage with a mysterious seismic signal. Thwarted by internal CIA politics, they put their careers at risk to engage in an unauthorized consultation with Jason, the secret group of physicists who consult for the government. Astrophysicist Alex Runyan advances a fantastic theory that triggers a race for the truth before the conflict with Russia can spin out of control. The quest leads to the New Mexico laboratory of Paul Krone. The true danger dwarfs that posed by the international crisis. Bonus links to historical background material are provided at the end of the book. The Krone saga continues in the sequel, Krone Ascending, also available for Kindle.

    Provides a review of introductory noncalculus-based physics for those who do not have a strong background in mathematics.

    Written for the engineer as well as the race car enthusiast, the authors, who developed many of the original vehicle dynamics theories and principles covered in this book, including the Moment Method, pair analysis and lap time simulation, include much information that is not available in any other vehicle dynamics text.

    But what if, nonetheless, Einstein got it wrong?Since the 1930s, physicists have noticed an alarming discrepancy between the universe as we see it and the universe that Einstein's theory of relativity predicts. There just doesn't seem to be enough stuff out there for everything to hang together. Galaxies spin so fast that, based on the amount of visible matter in them, they ought to be flung to pieces, the same way a spinning yo-yo can break its string. Cosmologists tried to solve the problem by positing dark matter—a mysterious, invisible substance that surrounds galaxies, holding the visible matter in place—and particle physicists, attempting to identify the nature of the stuff, have undertaken a slew of experiments to detect it. So far, none have.Now, John W. Moffat, a physicist at the Perimeter Institute for Theoretical Physics in Waterloo, Canada, offers a different solution to the problem. The cap­stone to a storybook career—one that began with a correspondence with Einstein and a conversation with Niels Bohr—Moffat's modified gravity theory, or MOG, can model the movements of the universe without recourse to dark matter, and his work chal­lenging the constancy of the speed of light raises a stark challenge to the usual models of the first half-million years of the universe's existence.This bold new work, presenting the entirety of Moffat's hypothesis to a general readership for the first time, promises to overturn everything we thought we knew about the origins and evolution of the universe.
