Book Description
Barnes Wallisrsquo;s work covers far more than just basketwork bombers and bouncing bombs. So how did his engineering genius take ideas from airships and push them forward to aircraft faster than Concorde? Barnes Wallis is best known as thersquo; boffinrsquo; behind the famous bouncing bomb used by 617 Squadron to breach the Ruhr dams in 1943, but his work covers a far wider canvas. It ranges from airships, through novel aircraft structures and special weapons to long-range supersonic aircraft, and an extensive patent portfolio. This book describes the huge breadth of Wallisrsquo;s work. It shows why his genius brought totally new ideas into these fields, and reveals the science and engineering expertise that he deployed to make them work.

Book Description
In 1922 Barnes Wallis FRS, who later invented the transatlantic airship and the bouncing bomb immortalized in the movie The Dam Busters, fell in love for the first and last time - aged 35. The object of his affection, Molly Bloxam, was 17 and setting off to study science at University College London. Her father decreed that the two could correspond only if Barnes taught Molly mathematics in his letters. Mathematics with Love presents, for the first time, the result of this curious diktat: a series of witty, tender and totally accessible introductions to calculus, trigonometry and electrostatic induction that remarkably, wooed and won the girl. Deftly narrated by Barnes and Molly's daughter Mary, Mathematics with Love is an evocative tale of a twenties courtship, a surprising insight into the early life of an engineering genius - and a great way to learn a little mathematics.

Book Description
THE SUNDAY TIMES BESTSELLER A masterly history of the Dambusters raid from bestselling and critically acclaimed Max Hastings. Operation Chastise, the overnight destruction of the Möhne and Eder dams in north-west Germany by the RAF's 617 Squadron, was an epic that has passed into Britain's national legend. Max Hastings grew up embracing the story, the classic 1955 movie and the memory of Guy Gibson, the 24-year-old wing-commander who won the VC leading the raid. In the 21st Century, however, Hastings urges that we should review the Dambusters in much more complex shades. The aircrew's heroism was wholly authentic, as was the brilliance of Barnes Wallis, who invented the 'bouncing bombs'. But commanders who promised their young fliers that success could shorten the war fantasised wildly. What Germans call the Möhnekatastrophe imposed on the Nazi war machine temporary disruption, rather than a crippling blow. Hastings vividly describes the evolution of Wallis' bomb, and of the squadron which broke the dams at the cost of devastating losses. But he also portrays in harrowing detail those swept away by the torrents. Some 1,400 civilians perished in the biblical floods that swept through the Möhne valley, more than half of them Russian and Polish women, slave labourers under Hitler. Ironically, Air Marshal Sir Arthur 'Bomber' Harris gained much of the credit, though he opposed Chastise as a distraction from his city-burning blitz. He also made what the author describes as the operation's biggest mistake - the failure to launch a conventional attack on the Nazis' huge post-raid repair operation, which could have transformed the impact of the dam breaches upon Ruhr industry. Chastise offers a fascinating retake on legend by a master of the art. Hastings sets the dams raid in the big picture of the bomber offensive and of the Second World War, with moving portraits of the young airmen, so many of whom died; of Barnes Wallis; the monstrous Harris; the tragic Guy Gibson, together with superb narrative of the action of one of the most extraordinary episodes in British history.

Book Description
At the dawn of the twentieth century mankind had not yet achieved powered flight. The main motive power then was provided by steam engines – heavy, dirty and inefficient. If one wanted to travel ‘over seas’ one had to travel on them. A journey from London to New York, by steam-driven train and ship, took more than 6 days. By the time the same century drew to a close in December 1999, air travel was the normal choice for long journeys. Millions of people every day flew comfortably and safely in pressurised aluminium airliners propelled by simple, clean and efficient gas turbine engines. The same journey from London to New York could be achieved at supersonic speed in less than 6 hours. For much of that century, many of the extraordinary developments that moved aviation from fragile wood and fabric biplanes to supersonic transports were achieved on 330 acres of low-lying former estate farmland in Surrey, England. The estate was called Brooklands. Those marshy acres were transformed from 1907 into the world’s first custom-built motor-racing circuit, then a rapidly developing aerodrome, and finally one of the country’s largest aircraft factories, employing tens of thousands of people. Nearly 19,000 aircraft of many different types were built at Brooklands during nine decades of peace and war. By the 1980s however it was being eclipsed by larger manufacturing sites elsewhere, with longer runways and better communications links; its owner, by then called British Aerospace, finally closed the factory in 1989. This book tells the history of those amazing developments through 100 of the key aircraft, engines, places and other objects that can still be seen, either in or near Brooklands Museum or in other locations around the country. It also highlights the stories of six designers whose inspiring creativity produced aircraft, engines and weapons ranging from Camel to Concorde, Fury to Harrier, Wellington to Viscount, Merlin to Olympus. Between them, Thomas Sopwith, Barnes Wallis, Rex Pierson, Sydney Camm, Stanley Hooker and George Edwards were responsible for much of what was designed, built and flown, not only at Brooklands but elsewhere too. The book is arranged in successive historical episodes but the many links between the objects and the designers should allow readers to follow different paths if they so wish. It is not intended as a technical reference but rather to inspire the reader to seek out the objects and discover more about them.

Book Description
One of the most well-known and loved stories of Jesus's ministry is the encounter with the Samaritan woman at Jacob's well. Now the creative mind of Diana Wallis Taylor imagines how the Samaritan woman got there in the first place. Marah is just a girl of thirteen when her life is set on a path that will eventually lead her to a life-changing encounter with the Messiah. But before that momentous meeting she must traverse through times of love lost and found, cruel and manipulative men, and gossiping women. This creative and accurate portrayal of life in the time of Jesus opens a window into a fascinating world. Taylor's rich descriptions of the landscapes, lifestyles, and rituals mesh easily with the emotional and very personal story of one woman trying to make a life out of what fate seems to throw at her. This exciting and heartwrenching story will fascinate readers and lend new life to a familiar story.

Book Description
When we start with the wrong question, no matter how good an answer we get, it won’t give us the results we want. Rather than joining the throngs who are asking, When will this economic crisis be over? Jim Wallis says the right question to ask is How will this crisis change us? The worst thing we can do now, Wallis tells us, is to go back to normal. Normal is what got us into this situation. We need a new normal, and this economic crisis is an invitation to discover what that means. Some of the principles Wallis unpacks for our new normal are . . . • Spending money we don’t have for things we don’t need is a bad foundation for an economy or a family. • It’s time to stop keeping up with the Joneses and start making sure the Joneses are okay. • The values of commercials and billboards are not the things we want to teach our children. • Care for the poor is not just a moral duty but is critical for the common good. • A healthy society is a balanced society in which markets, the government, and our communities all play a role. • The operating principle of God’s economy says that there is enough if we share it. • And much, much more . . . In the pages of this book, Wallis provides us with a moral compass for this new economy—one that will guide us on Wall Street, Main Street, and Your Street. Embracing a New Economy Getting back to "the way things were" is not an option. It is time we take our economic uncertainty and use it to find some moral clarity. Too often we have been ruled by the maxims that greed is good, it’s all about me, and I want it now. Those can be challenged only with some of our oldest and best values—enough is enough, we are in it together, and thinking not just for tomorrow but for future generations. Jim Wallis shows that the solution to our problems will be found only as individuals, families, friends, churches, mosques, synagogues, and entire communities wrestle with the question of values together.
