But there is one other crucial factor, which is much less well known. The same team had done it before. The truth is that many of those most closely involved in cracking the Enigma code – Alistair Denniston, Frank Birch, Dilly Knox – had wrestled with German naval codes for most of the First World War. By the end of the war they had been successfully cracking a new code every day, from their secret Room 40 at the Old Admiralty Building, in a London blacked out for Zeppelin Raids.The techniques they developed then, the ideas that they came to rely on, the people they came to trust, had been developed the hard way, under intense pressure and absolute secrecy during World War I. Before Enigma tells their story and explains how they managed to crack the supposedly indecipherable code. The book outlines the capture of the Magdeburg and the Hobart, discusses the use of cracked codes to bring German fleets to battle at Dogger Bank and Jutland, and focuses on individuals such as Winston Churchill and Admiral Sir Reginald ‘Blinker’ Hall and their importance in the development of a British naval code tradition.

    The British expected R.101 to spearhead a fleet of imperial airships that would dominate the skies as British naval ships, a century earlier, had ruled the seas. The dream ended when, on its demonstration flight to India, R.101 crashed in France, tragically killing nearly all aboard.Combining meticulous research with superb storytelling, Fatal Flight guides us from the moment the great airship emerged from its giant shed—nearly the largest building in the British Empire—to soar on its first flight, to its last fateful voyage. The full story behind R.101 shows that, although it was a failure, it was nevertheless a supremely imaginative human creation. The technical achievement of creating R.101 reveals the beauty, majesty, and, of course, the sorrow of the human experience.The narrative follows First Officer Noel Atherstone and his crew from the ship’s first test flight in 1929 to its fiery crash on October 5, 1930. It reveals in graphic detail the heroic actions of Atherstone as he battled tremendous obstacles. He fought political pressures to hurry the ship into the air, fended off Britain’s most feted airship pilot, who used his influence to take command of the ship and nearly crashed it, and, a scant two months before departing for India, guided the rebuilding of the ship to correct its faulty design. After this tragic accident, Britain abandoned airships, but R.101 flew again, its scrap melted down and sold to the Zeppelin Company, who used it to create LZ 129, an airship even more mighty than R.101—and better known as the Hindenburg. Set against the backdrop of the British Empire at the height of its power in the early twentieth century,Fatal Flight portrays an extraordinary age in technology, fueled by humankind’s obsession with flight.

It is the perfect photographic field guide for the birdwatching beginner.

    Set in Edwardian London and on the stormy coasts of Cornwall, Cape Cod, and Nova Scotia, Thunderstruck evokes the dynamism of those years when great shipping companies competed to build the biggest, fastest ocean liners, scientific advances dazzled the public with visions of a world transformed, and the rich outdid one another with ostentatious displays of wealth. Against this background, Marconi races against incredible odds and relentless skepticism to perfect his invention: the wireless, a prime catalyst for the emergence of the world we know today. Meanwhile, Crippen, “the kindest of men,” nearly commits the perfect crime. With his superb narrative skills, Erik Larson guides these parallel narratives toward a relentlessly suspenseful meeting on the waters of the North Atlantic. Along the way, he tells of a sad and tragic love affair that was described on the front pages of newspapers around the world, a chief inspector who found himself strangely sympathetic to the killer and his lover, and a driven and compelling inventor who transformed the way we communicate. Thunderstruck presents a vibrant portrait of an era of séances, science, and fog, inhabited by inventors, magicians, and Scotland Yard detectives, all presided over by the amiable and fun-loving Edward VII as the world slid inevitably toward the first great war of the twentieth century. Gripping from the first page, and rich with fascinating detail about the time, the people, and the new inventions that connect and divide us, Thunderstruck is splendid narrative history from a master of the form.

    Vallee Introduction by Burt Rutan Commentary by Tom Clancy A never-before-heard firsthand account of a government insider’s experience on the cutting edge of UFO exploration; includes a new afterword “Forget everything you think you know about UFOs - this insider's account exposes the reality... Packed with top grade information, insightful analysis and fascinating anecdotes, Alexander's interesting and controversial book sets the gold standard for titles on this subject.†–Nick Pope, author of Open Skies, Closed Minds “Changes the playing field for both true believers and skeptics alike. Alexander strongly warns, be careful what you wish for when asking for presidential intervention.  Success could set the field of ufology back decades.†--George Noory, host of Coast to Coast AM While still on active duty in the U.S. Army during the 1980s, Colonel John B. Alexander, Ph.D. created an interagency group to explore the controversial topic of UFOs. All members held Top Secret clearance. What they discovered was not at all what was expected. UFOs covers the numerous cases they saw, and answers questions like: • What was really in Hanger 18? • Did a UFO land at Holloman Air Force Base? • What happened at Roswell? • What is Majestic 12? • What is the Aviary? • What does the government know about UFOs? • What has happened with disclosure in other countries? • Has the U.S. reverse engineered a UFO? • Why don’t presidents get access to UFO info? UFOs is at once a complete account of Alexander’s findings, and a call to action. There are no conspiracy theories here—only hard facts—but they are merely the beginning.

    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.

    Some had got lost, others were brought by defectors; some were lured through electronic countermeasures by the RAF, others brought down in unusual combat circumstances. All manner of types appeared He111, Go145, Me110, Ju88, Me109 F and G, FW190, Do217 and all were of great interest to the RAF. In some cases aircraft were repaired and test flown, betraying vital and invaluable information. Distinguished author Andy Saunders examines a selection of such fascinating cases and draws upon his own research, interviews, official reports and eyewitness accounts to bring alive these truly unusual accounts, all richly illustrated with contemporary photographs."
