Ordinary folks can construct 13 awesome ballistic devices in their garage or basement workshops using inexpensive household or hardware store materials and this step-by-step guide. Clear instructions, diagrams, and photographs show how to build projects ranging from the simple a match-powered rocket to the more complex a scale-model, table-top catapult to the offbeat a tennis ball cannon. With a strong emphasis on safety, the book also gives tips on troubleshooting, explains the physics behind the projects, and profiles scientists and extraordinary experimenters such as Alfred Nobel, Robert Goddard, and Isaac Newton. This book will be indispensable for the legions of backyard toy-rocket launchers and fireworks fanatics who wish every day was the fourth of July.
L szl B r 's last name is, in much of the world, a synonym for his revolutionary writing tool. But few people know that B r began his career in interwar Budapest as a journalist frustrated with spotty ink; that he escaped fascism by fleeing to Paris and, finally, to Buenos Aires; that a fellow Hungarian, Andor Goy, also played a vital role in the pen's development⎯and that, in a tragic twist of shared fate, business pressures and politics ultimately deprived both men of their rights to the ballpoint pen. Taking us from Hitler's Europe in 1938, to Argentina, where B r settled, and to Communist-era Hungary, where Goy lived out his life, Ballpoint is a painstakingly researched, absorbing narrative that reads simultaneously like a work of history and a novel.
Gy rgy Moldova is one of Hungary's most successful--and prolific--writers, and he is respected in particular for his achievements on the nonfiction front. He has earned the Kossuth Prize, Hungary's most prestigious literary honor, and his work has been translated into many languages, including English, German, Russian, and Chinese. He is the only Hungarian author to have achieved sales of 600,000 copies, and he continues to fare well in the country's bestseller lists to this day. Born in 1934, he lives in Budapest with his family. The author lives in Budapest.
"Mr. Moldova tells this tale of ingenuity and disappointed hopes with considerable verve; his book is a page-turner." ⎯Wall Street Journal
"In terms of history-making inventions, the ballpoint pen is no electric light bulb, but its story is far wilder." ⎯Maclean's (Canada's leading news magazine)
"Ballpoint reads like a fast-paced mystery. Although we know from the start that its technological protagonist⎯the ballpoint pen⎯will triumph, we find ourselves repeatedly surprised by the story's unfolding episodes of international intrigue, financial deception, and legal shenanigans." ⎯Henry Petroski, author of The Pencil and The Essential Engineer
"Part biography, part historical novel, this fascinating book tells the remarkable story of L szl B r and Andor Goy, the two Hungarians who made the first workable ballpoint pen and who, despite the resounding success of their product, earned almost nothing from it." ⎯John Emsley, author of Molecules of Murder and The Elements of Murder
"The tale of L szl B r and Andor Goy ... is a wonderful illustration of the role that human passions, foibles, and genius play in shaping the world around us." ⎯Robert Friedel, author of Zipper: An Exploration in Novelty
The Barefoot Navigator introduces the navigation skills of the ancients--methods using the sun, sea, wind, and stars, and even the flight patterns of ocean birds. The Barefoot Navigator also shows today's sailors how to apply these methods to augment--and in the case of emergency, replace-their modern navigation systems. And it not just for emergencies--sometimes it is just plain fun to create a simple astrolabe or polar stick and confirm what your GPS tells you.
Polynesians managed to populate an area of ocean larger than North America simply by analyzing clouds, currents, and wind direction--how did they do it? In the first portion of The Barefoot Navigator Lagan introduces these ancient seafarers and their powerful, accurate--and seemingly simple--navigation techniques. We also learn that the Vikings routinely traveled on the notorious stretches of water between Iceland, Greenland, and Scandinavia--no charts, no GPS; it seems mind-boggling but Lagan shows us how. The second section of The Barefoot Navigator teaches how to combine these ancient techniques--and even construct the simple devices if we desire-with today's modern navigational devices, especially in emergency situations (loss of power, loss of signal), to ensure a constant grasp on your vessel's location--no matter what.
Interlacing fascinating history with useful advice and enjoyable writing, The Barefoot Navigator is unlike every other navigation reference out there.

From a Pulitzer Prize-winning journalist and Los Angeles Times contributor, the untold story of how science went "big," built the bombs that helped win World War II, and became dependent on government and industry--and the forgotten genius who started it all, Ernest Lawrence.Since the 1930s, the scale of scientific endeavors has grown exponentially. Machines have become larger, ambitions bolder. The first particle accelerator cost less than one hundred dollars and could be held in its creator's palm, while its descendant, the Large Hadron Collider, cost ten billion dollars and is seventeen miles in circumference. Scientists have invented nuclear weapons, put a man on the moon, and examined nature at the subatomic scale--all through Big Science, the industrial-scale research paid for by governments and corporations that have driven the great scientific projects of our time. The birth of Big Science can be traced to Berkeley, California, nearly nine decades ago, when a resourceful young scientist with a talent for physics and an even greater talent for promotion pondered his new invention and declared, "I'm going to be famous " Ernest Orlando Lawrence's cyclotron would revolutionize nuclear physics, but that was only the beginning of its impact. It would change our understanding of the basic building blocks of nature. It would help win World War II. Its influence would be felt in academia and international politics. It was the beginning of Big Science. This is the incredible story of how one invention changed the world and of the man principally responsible for it all. Michael Hiltzik tells the riveting full story here for the first time.
