Your very belief is tested in combat, you must kill your enemy, or your enemy will kill you – that is the simple, hard cold fact. Because in my humble opinion, War is hell on Earth. Evil roams freely in War, and it will kill you, one way or another, with its evil intent. Nightmares are common and, in their fantasy, never reflect the real horror and the reality that War can bring to your mind. No matter what your personal spiritual beliefs are, you will be tested. The conduct of your intent will be your judge for life. It is your second guessing that can be dangerous to you. A wise Philosopher once said in Greece, “If you want real peace, you must always prepare for War.” This book is about war. It tells my experiences of the paths I took as a United States Marine in Vietnam. The mouths of many soldiers will say the same – the same soldiers who had shared my paths with the experiences of my many paths in life. I have not shared these words or reflections with anyone, except in bits and pieces, and that too, with other veterans in the form of bunker talk.

    The space shuttle Columbia disintegrated 37 miles above Texas, seven brave astronauts were killed and America's space program, always an eyeblink from disaster, suffered its second catastrophic in-flight failure. Unlike the Challenger disaster 17 years earlier, Columbia's destruction left the nation one failure away from the potential abandonment of human space exploration. Media coverage in the immediate aftermath focused on the possible cause of the disaster, and on the nation's grief. But the full human story, and the shocking details of NASA's crucial mistakes, have never been told -- until now.Based on dozens of exclusive interviews, never-before-published documents and recordings of key meetings obtained by the authors, "Comm Check" takes the reader inside the conference rooms and offices where NASA's best and brightest managed the nation's multi-billion-dollar shuttle program -- and where they failed to recognize the signs of an impending disaster. It is the story of a space program pushed to the brink of failure by relentless political pressure, shrinking budgets and flawed decision making. The independent investigation into the disaster uncovered why Columbia broke apart in the sky above Texas. "Comm Check" brings that story to life with the human drama behind the tragedy.Michael Cabbage and William Harwood, two of America's most respected space journalists, are veterans of all but a handful of NASA's 113 shuttle missions. Tapping a network of sources and bringing a combined three decades of experience to bear, the authors provide a rare glimpse into NASA's inner circles, chronicling the agency's most devastating failure andthe challenges that face NASA as it struggles to return America to space.

    In this amazingly comprehensible history of the universe, Simon Singh decodes the mystery behind the Big Bang theory, lading us through the development of one of the most extraordinary, important, and awe-inspiring theories in science.

    It has, among many other achievements, revealed thousands of galaxies in what seemed to be empty patches of sky; transformed our knowledge of black holes; found dwarf planets with moons orbiting other stars; and measured precisely how fast the universe is expanding. In Handprints on Hubble, retired astronaut Kathryn Sullivan describes her work on the NASA team that made all of this possible. Sullivan, the first American woman to walk in space, recounts how she and other astronauts, engineers, and scientists launched, rescued, repaired, and maintained Hubble, the most productive observatory ever built.Along the way, Sullivan chronicles her early life as a “Sputnik Baby,” her path to NASA through oceanography, and her initiation into the space program as one of “thirty-five new guys.” (She was also one of the first six women to join NASA's storied astronaut corps.) She describes in vivid detail what liftoff feels like inside a spacecraft (it's like “being in an earthquake and a fighter jet at the same time”), shows us the view from a spacewalk, and recounts the temporary grounding of the shuttle program after the Challenger disaster.Sullivan explains that “maintainability” was designed into Hubble, and she describes the work of inventing the tools and processes that made on-orbit maintenance possible. Because in-flight repair and upgrade was part of the plan, NASA was able to fix a serious defect in Hubble's mirrors—leaving literal and metaphorical “handprints on Hubble.”Handprints on Hubble was published with the support of the MIT Press Fund for Diverse Voices.

    Now he makes the case that living on Mars is not just plausible, but inevitable.It sounds like science fiction, but Stephen Petranek considers it fact: Within twenty years, humans will live on Mars. We'll need to. In this sweeping, provocative book that mixes business, science, and human reporting, Petranek makes the case that living on Mars is an essential back-up plan for humanity and explains in fascinating detail just how it will happen.The race is on. Private companies, driven by iconoclastic entrepreneurs, such as Elon Musk, Jeff Bezos, Paul Allen, and Sir Richard Branson; Dutch reality show and space mission Mars One; NASA; and the Chinese government are among the many groups competing to plant the first stake on Mars and open the door for human habitation. Why go to Mars? Life on Mars has potential life-saving possibilities for everyone on earth. Depleting water supplies, overwhelming climate change, and a host of other disasters — from terrorist attacks to meteor strikes — all loom large. We must become a space-faring species to survive. We have the technology not only to get humans to Mars, but to convert Mars into another habitable planet. It will likely take 300 years to "terraform" Mars, as the jargon goes, but we can turn it into a veritable second Garden of Eden. And we can live there, in specially designed habitations, within the next twenty years.In this exciting chronicle, Petranek introduces the circus of lively characters all engaged in a dramatic effort to be the first to settle the Red Planet. How We'll Live on Mars brings firsthand reporting, interviews with key participants, and extensive research to bear on the question of how we can expect to see life on Mars within the next twenty years.

    It doesn't matter how small the tunnel is you never know what's around the bend ... You don't know if it's abandoned, you don't know if it's booby trapped and you don't know why the tunnel is there in the first place."They were young, they were Australian, they were Army engineers and they were the first allied soldiers to risk their lives in the darkness of the Vietcong tunnels of South Vietnam. Staring death squarely in the face every day, not only did they follow their enemy down into these unknown underground labyrinths, but matched the Vietcong's jungle warfare skills and defused thousands of their clever booby traps.Off duty, it was a different story. The bad boys of 3 Field Troop were a boozing, brawling, bonking bunch of larrikins, who cut a swathe through the bars and brothels of Saigon, fought American Military Police to a standstill, built a secret casino and booby-trapped their own HQ to teach their officers a lesson.Thrilling, inspiring and action packed, this is the true story of the unsung heroes of Australia's war in Vietnam. Living up to their motto of 'We Make and We Break', they created the legend of the Tunnel Rats.

    A strong gravitational wave will briefly change that distance by less than the thickness of a human hair. We have perhaps less than a few tenths of a second to perform this measurement. And we don’t know if this infinitesimal event will come next month, next year or perhaps in thirty years.In 1916 Einstein predicted the existence of gravitational waves: miniscule ripples in the very fabric of spacetime generated by unfathomably powerful events. If such vibrations could somehow be recorded, we could observe our universe for the first time through sound: the hissing of the Big Bang, the whale-like tunes of collapsing stars, the low tones of merging galaxies, the drumbeat of two black holes collapsing into one. For decades, astrophysicists have searched for a way of doing so…In 2016 a team of hundreds of scientists at work on a billion-dollar experiment made history when they announced the first ever detection of a gravitational wave, confirming Einstein’s prediction. This is their story, and the story of the most sensitive scientific instrument ever made: LIGO.Based on complete access to LIGO and the scientists who created it, Black Hole Blues provides a firsthand account of this astonishing achievement: a compelling, intimate portrait of cutting-edge science at its most awe-inspiring and ambitious.

    Although it is usually seen as an unqualified success, the Battle for Normandy was actually a much more closely fought affair. In The D-Day Deception the author and journalist Alex Gerlis explores whether it would have been won at all without the Allied deception operation. It was not until the 1970s that details began to emerge the Allies’ top secret and audacious deception plan. Operation Fortitude succeeded in confusing the Germans about where the Allies were going to land: would it be Normandy, or the Pas de Calais? The D-Day Deception looks at the part the deception played in the eventual Allied victory and asks to what extent it may have been helped by those in the German High Command and intelligence organizations who by 1944 wanted to see a swift end to the war. Alex Gerlis was born in Grimsby, Lincolnshire and now lives with his family in West London. He was a BBC journalist for over 25 years, leaving in 2011 to concentrate on his writing. He is the author of The Best of Our Spies, a highly acclaimed espionage thriller based on D-Day and especially the deception operation that played a big part in its success. The Best of Our Spies was published in December 2012, since when it has featured prominently in the Amazon Kindle Spy best-selling lists and has over 180 Amazon reviews.

    Starting with this forgotten episode, 'Backroom Boys' tells the bittersweet story of how one country lost its industrial tradition and got back something else. Sad, inspiring, funny and ultimately triumphant, it follows the technologists whose work kept Concorde flying, created the computer game, conquered the mobile-phone business, saved the human genome for the human race - and who now are sending the Beagle 2 probe to burrow in the cinnamon sands of Mars. 'Backroom Boys' is a vivid love-letter to quiet men in pullovers, to those whose imaginings take shape not in words but in mild steel and carbon fibre and lines of code. Above all, it is a celebration of big dreams achieved with slender means.

    The memoir tells his story starting from the ambivalence he had about being drafted through the firefights and wounds he experienced in Vietnam to the estrangement he felt as he walked out of Walter Reed hospital into a civilian world not very interested in a faraway war. It also tells a tale of the commonplace courage of the twenty-year-old infantrymen of Charley Company, 5th of the 12th, 199th Light Infantry Brigade, and of the cowardice and character flaws of a Lieutenant more interested in his own glory and advancement than the well-being of his platoon. The good, the bad, and the ugly of a country and an army fighting a distant war for unclear purposes are all on display in this account focused on nine months of war in 1969.

    John Brockman brings together the world’s best-known physicists and science writers—including Brian Greene, Walter Isaacson, Nobel Prize-winners Murray Gell-Mann and Frank Wilczek, and Brian Cox—to explain the universe in all wondrous splendor.In Universe, today’s most influential science writers explain the science behind our evolving understanding of the universe and everything in it, including the cutting edge research and discoveries that are shaping our knowledge.Lee Smolin reveals how math and cosmology are helping us create a theory of the whole universe Brian Cox offers new dimensions on the Large Hadron and the existence of a Higgs-Boson particle Neil Turok analyzes the fundamental laws of nature, what came before the big bang, and the possibility of a unified theory.Seth Lloyd investigates the impact of computational revolutions and the informational revolution Lawrence Krauss provides fresh insight into gravity, dark matter, and the energy of empty space Brian Greene and Walter Isaacson illuminate the genius who revolutionized modern science: Albert Einstein and much more.Explore the Universe with some of today’s greatest minds: what it is, how it came into being, and what may happen next.

    Beyond tells the epic story of humanity leaving home—and how humans will soon thrive in the vast universe beyond the earth.A dazzling and propulsive voyage through space and time, Beyond reveals how centuries of space explorers—from the earliest stargazers to today’s cutting-edge researchers—all draw inspiration from an innate human emotion: wanderlust. This urge to explore led us to multiply around the globe, and it can be traced in our DNA.Today, the urge to discover manifests itself in jaw-dropping ways: plans for space elevators poised to replace rockets at a fraction of the cost; experiments in suspending and reanimating life for ultra-long-distance travel; prototypes for solar sails that coast through space on the momentum of microwaves released from the Earth. With these ventures, private companies and entrepreneurs have the potential to outpace NASA as the leaders in a new space race.Combining expert knowledge of astronomy and avant-garde technology, Chris Impey guides us through the heady possibilities for the next century of exploration. In twenty years, a vibrant commercial space industry will be operating. In thirty years, there will be small but viable colonies on the Moon and Mars. In fifty years, mining technology will have advanced enough to harvest resources from asteroids. In a hundred years, a cohort of humans born off-Earth will come of age without ever visiting humanity’s home planet. This is not the stuff of science fiction but rather the logical extension of already available technologies.Beyond shows that space exploration is not just the domain of technocrats, but the birthright of everyone and the destiny of generations to come. To continue exploration is to ensure our survival. Outer space, a limitless unknown, awaits us.

    There are deep connections between stars and atoms, between the cosmos and the microworld. Just six numbers, imprinted in the "big bang," determine the essential features of our entire physical world. Moreover, cosmic evolution is astonishingly sensitive to the values of these numbers. If any one of them were "untuned," there could be no stars and no life. This realization offers a radically new perspective on our universe, our place in it, and the nature of physical laws.

    These special missions were called “Advanced Force Operations.” Subsequently, these special teams brought in the rest of the Green Berets during an operation called "the Ugly Baby." Then, one of the most significant battles in Special Forces history occurred: "Operation Viking Hammer," where six Green Beret teams along with a handful of CIA and Air Force Special Ops personnel, combined with approximately 8000 Peshmerga, took back hundreds of square kilometers from almost 1000 Ansar Al Islam extremists, and secured a poison production facility of national level significance. This book is the only firsthand account of these essential Unconventional Warfare operations, written by an operator who was there. In addition to describing these historically significant Special Operations missions, "One Green Beret" also details a 15-year career in the Green Berets that includes many unique experiences, such as joint operations alongside Russian Spetznaz on the northern border of Kosovo, and postwar operations in Bosnia embedded deeply with the locals. Mark Giaconia questions everything, and provides a VERY humble, sobering, and human perspective on war, military service, and strategic considerations. One Green Beret is very inspiring, and conveys the author’s personal evolution from gunslinger to educated computer scientist; a true tale of “post traumatic success.”
