Who knew that he also was a pivotal figure in the development of the airplane, the hydrofoil, genetic engineering, and more? Charlotte Gray does, and she tells us how and why she brought to life the passionate mind and heart of the man behind so many amazing ideas and innovations. --Lauren Nemroff Some Questions for Charlotte Gray [image] 1. Most people picture Alexander Graham Bell as that grandfatherly looking man with a long white beard who invented the telephone. What's wrong with that image? The image of Alexander Graham Bell as a kindly Santa Claus figure is the one we all know: It is as familiar as the one of Einstein with his hair in a frizzy grey mass. But when Alexander Graham Bell was struggling to invent the telephone, he was a skinny, clean-shaven, neurotically intense young man and a hypochondriac, with obsessive work habits and a very volatile nature. Reading his letters and journals, I was shocked to discover how often he would ricochet between euphoria and depression. Invention was Alexander Graham Bell's passion, but I frequently wondered whether, if he had not had an early success and the right wife, his difficult personality would have prevented him achieving anything. I think it is important to revise the grandfatherly stereotype of Bell in order to show that invention is difficult, and inventors are not easy, placid people to live with. 2. In what way does Bell's genius different from other inventors of his age, such as Thomas Edison or the Wright brothers? The wonderful thing about the inventions of such nineteenth century giants as Bell, Edison and the Wright brothers is that, with a little bit of effort, even those of us who never did Grade 12 physics can actually understand how their inventions worked. One could never say that about today's microelectronic technology. Intuition and imagination were all crucial for the breakthroughs made by Edison, the Wright brothers and Bell. However, what sets Bell apart from Edison and the Wright brothers was that he didn't have an entrepreneurial bone in his body. He was more like a holdover from the eighteenth century Enlightenment, while the others were go-getting twentieth-century hustlers. Edison was always looking for financial backers; he announced his breakthroughs before he had even built working prototypes; he was one of the first inventors to put together a real R and D team at a purpose-built laboratory, at Menlo Park. He understood that invention is, in his own words, "One percent inspiration, ninety percent perspiration." Similarly the Wright Brothers were eager to make money out of their flying machines. They refused to share their technological breakthroughs, guarded their patents fiercely, and wouldn't give any demonstrations to the public of their biplanes. Bell was the opposite--totally absorbed in extending the frontiers of knowledge, and completely careless about commercial exploitation of his ideas. 3. Is it true that "necessity is the mother of invention" or is it something else? Invention has many mothers - the right materials, a widespread understanding that this will improve the world in some way, the right individual to pursue the elusive dream. In the case of the telephone, one can argue that there was no overwhelming necessity for a new form of communication: the telegraph had been working well for 30 years, and only a few people realized that a device that could carry the human voice, rather than the Morse code, would pull people together in a revolutionary way. As soon as telephones appeared in the market, their advantages were obvious. But there was still incredible resistance. In Britain, the upper classes were slow to acquire telephones because they posed a class issue: who should answer them? Everybody knew that, in a house with servants, the servant answered the door when the telegraph boy rang the bell. But should master or servant speak on the phone? The democratic nature of the telephone--anybody could use it, not just qualified operators--also shackled its spread. In Russia after the revolution, Stalin is said to have vetoed the idea of a modern telephone system. "It will unmake our work," the dictator decreed. "No greater instrument for counter-revolution and conspiracy can be imagined." So did necessity drive the invention of the telephone? No--when Bell first started speculating on its impact, people thought he was mad. But it quickly became a total necessity…imagine life without electronic communication today! 4. It was amazing to learn that Bell's mother and his wife were both deaf, and that from an early age he was immersed in research on the nature of sound and oral communication. How important were these personal relationships in shaping his outlook and inventions? One of my greatest surprises when I started research for Reluctant Genius was the discovery that Bell's first ambition was to be a teacher of the deaf, and that he remained committed to the cause of improved education for the hearing impaired throughout his life. I had no idea of this side of him, or of his long relationship with Helen Keller. The fact that the two most important women in his life, his mother and his wife, were deaf was of crucial importance both to his own work, and to his attitude to others. His respect for their intelligences and personalities meant that, unlike many of his contemporaries, he never assumed that deafness was linked to intellectual disability. Moreover, his scientific interest in their condition informed his telephone research. Because he knew why their ears didn't work, he understood how sound should reach the brain in a hearing person's ear, through the ear drum. None of his competitors made that intuitive leap. Their early attempts to build working telephones were foiled because they didn't include the diaphragm that mimicked the action of the ear drum, and which was the key feature of Bell's first phone. Lastly, Bell was also fascinated by the intergenerational transmission of deafness. This led to his research on genetics in general - and the program he initiated at his summer home, in Cape Breton, to breed a flock of "super sheep" that would always have twin births. 5. Bell's wife, Mabel Hubbard Bell, was a remarkable person in her own right. Why was it so important to tell her story? Too often, biographies of "Great Men" suggest they achieved everything by their own efforts. A few did, of course, but most depended on the support and encouragement of others--parents, partners, associates--to provide the right environment in which they could achieve their goals. Behind every great man….This was the case with Alexander Graham Bell. He would always have had his "Eureka Moment", in the summer of 1874, when he realized how a "talking telegraph" might work. But without Mabel, we probably would never have heard of him. He would not have patented the invention or found the business partners who helped him moved his invention from the laboratory to the market place. Mabel's father, Gardiner Hubbard, was his patent lawyer: Mabel herself ensured that he went to the Philadelphia Exposition, in 1876, to demonstrate his new apparatus. In later years, Mabel provided all kinds of other practical help, in ensuring that her exasperating husband could focus on his inventions. She handled the financial side of their marriage: she found qualified young men who could help him work on his flying machines: she was always cheering him up and stroking his ego when he got depressed. And she created, along with their two daughters, a warm family environment which gave balance to Bell's life - and which so many of his contemporaries, including Thomas Edison, never enjoyed. I was determined to give Mabel her due in the story of Bell. I found her such an attractive and intriguing figure. She was stone deaf, ten years younger than her husband, and their relationship began as a teacher-student one. It would be easy to assume that this brilliant, world famous man would be the dominant figure in the relationship. In fact, the reverse is true. 6. What do you think Bell would think of cell phones, the internet and other wireless means of communication? Bell himself anticipated "electric communication": he was very frustrated by how long it took for a letter from Nova Scotia to reach Europe. I'm sure he would be delighted by the internet. However, he would be appalled by the constant buzz of other technological advances, and the way we've allowed them to trump all other forms of human intercourse. This is a man who wouldn't have a telephone in his own study, because its ring would disturb his train of thought. He was a gracious, well-mannered man who would have been horrified by the way many of us let our cell phones to interrupt our face-to-face conversations. And if somebody pulled out a Blackberry and started punching into it while Bell was speaking of him--well, Alec would have muttered, "Shee-e-esh" (the nearest he ever got to swearing) and stomped out of the room. 7. What was the most exciting research discovery that you made? As a biographer, I have to say that my most exciting discovery was the wealth of material I had to work with. Because Alexander Graham Bell could never speak to his wife on the telephone, he and Mabel exchanged long, intimate, colourful letters whenever they were apart--and that was often. I was thrilled to discover, at the Alexander Graham Bell Historic Site in Baddeck, Nova Scotia, 180 three-ring binders of family correspondence (another set is housed at the Library of Congress, Washington.) These letters let me explore the inner-workings of the mind of a genius, and of a remarkable marriage, in a way that I had hardly dared hope for. I was also amazed at the range of Bell's activities. The telephone, the photophone (which sent sounds down beams of light), an early iron lung, a desalination process for salt water, flying machines, hydrofoils, genetic experiments…his scientific interests were enormously varied. And at the same time, he was doing so much else, for example with the Smithsonian Institute, and the National Geographic Society. And throughout his career, there was his long-running commitment to deaf education. It was hard not to be overwhelmed! 8. What are you working on right now? Yes, I'm already launched on my next biography. (In fact, I find it very hard not to start my next book before the previous one is even in the stores--I have a psychological need to live both my own life and someone else's!) My next project is a short biography of Nellie McClung, the Canadian author and political activist.

    Vaughn Vernon couples guided approaches to implementation with modern architectures, highlighting the importance and value of focusing on the business domain while balancing technical considerations.Building on Eric Evans’ seminal book, Domain-Driven Design, the author presents practical DDD techniques through examples from familiar domains. Each principle is backed up by realistic Java examples–all applicable to C# developers–and all content is tied together by a single case study: the delivery of a large-scale Scrum-based SaaS system for a multitenant environment.The author takes you far beyond “DDD-lite” approaches that embrace DDD solely as a technical toolset, and shows you how to fully leverage DDD’s “strategic design patterns” using Bounded Context, Context Maps, and the Ubiquitous Language. Using these techniques and examples, you can reduce time to market and improve quality, as you build software that is more flexible, more scalable, and more tightly aligned to business goals.

    This book provides coverage of pedagogy, and other topics such as sources of on-the-job conflict, how to use informational interviews, and others.

    He constructed a fleet of customized unicycles and a flamethrowing trumpet, outfoxed Vegas casinos, and built juggling robots. He also wrote the seminal text of the digital revolution, which has been called “the Magna Carta of the Information Age.” His discoveries would lead contemporaries to compare him to Albert Einstein and Isaac Newton. His work anticipated by decades the world we’d be living in today—and gave mathematicians and engineers the tools to bring that world to pass.In this elegantly written, exhaustively researched biography, Jimmy Soni and Rob Goodman reveal Claude Shannon’s full story for the first time. It’s the story of a small-town Michigan boy whose career stretched from the era of room-sized computers powered by gears and string to the age of Apple. It’s the story of the origins of our digital world in the tunnels of MIT and the “idea factory” of Bell Labs, in the “scientists’ war” with Nazi Germany, and in the work of Shannon’s collaborators and rivals, thinkers like Alan Turing, John von Neumann, Vannevar Bush, and Norbert Wiener.And it’s the story of Shannon’s life as an often reclusive, always playful genius. With access to Shannon’s family and friends, A Mind at Play brings this singular innovator and creative genius to life.

    You can not study human nature from a book, you must study yourself and your neighbors. This book may help you to know what to look for and to understand what you find, but it can do little more than this. It is true, this text gives you many facts learned by psychologists, but you must verify the statements, or at least see their significance to you, or they will be of no worth to you. However, the facts considered here, properly understood and assimilated, ought to prove of great value to you. But perhaps of greater value will be the psychological frame of mind or attitude which you should acquire. The psychological attitude is that of seeking to find and understand the causes of human action, and the causes, consequences, and significance of the processes of the human mind. If your first course in psychology teaches you to look for these things, gives you some skill in finding them and in using the knowledge after you have it, your study should be quite worth while.

    Along the way, we encounter black holes, turtles, snakes, dragons, axe-sharpening, and yak-shaving—and take a guided tour through the theories and methods, both brilliant and misguided, that litter the history of software development, from the famous ‘mythical man-month’ to Extreme Programming. Not just for technophiles but for anyone captivated by the drama of invention, Dreaming in Code offers a window into both the information age and the workings of the human mind.

    Through the worst years of the Great Depression as many as five thousand laborers toiled twenty-four hours a day, seven days a week, to erect the huge structure that would harness the Colorado River and transform the American West.Construction of the giant dam was a triumph of human ingenuity, yet the full story of this monumental endeavor has never been told. Now, in an engrossing, fast-paced narrative, Joseph E. Stevens recounts the gripping saga of Hoover Dam. Drawing on a wealth of material, including manuscript collections, government documents, contemporary newspaper and magazine accounts, and personal interviews and correspondence with men and women who were involved with the construction, he brings the Hoover Dam adventure to life.Described here in dramatic detail are the deadly hazards the work crews faced as they hacked and blasted the dam’s foundation out of solid rock; the bitter political battles and violent labor unrest that threatened to shut the job down; the deprivation and grinding hardship endured by the workers’ families; the dam builders’ gambling, drinking, and whoring sprees in nearby Las Vegas; and the stirring triumphs and searing moments of terror as the massive concrete wedge rose inexorably from the canyon floor.Here, too, is an unforgettable cast of characters: Henry Kaiser, Warren Bechtel, and Harry Morrison, the ambitious, headstrong construction executives who gambled fortune and fame on the Hoover Dam contract; Frank Crowe, the brilliant, obsessed field engineer who relentlessly drove the work force to finish the dam two and a half years ahead of schedule; Sims Ely, the irascible, teetotaling eccentric who ruled Boulder City, the straightlaced company town created for the dam workers by the federal government; and many more men and women whose courage and sacrifice, greed and frailty, made the dam’s construction a great human, as well as technological, adventure.Hoover Dam is a compelling, irresistible account of an extraordinary American epic.

    How has Google done it? Veteran technology reporter Steven Levy was granted unprecedented access to the company, and in this revelatory book he takes readers inside Google headquarters—the Googleplex—to show how Google works.While they were still students at Stanford, Google cofounders Larry Page and Sergey Brin revolutionized Internet search. They followed this brilliant innovation with another, as two of Google’s earliest employees found a way to do what no one else had: make billions of dollars from Internet advertising. With this cash cow, Google was able to expand dramatically and take on other transformative projects: more efficient data centers, open-source cell phones, free Internet video (YouTube), cloud computing, digitizing books, and much more.The key to Google’s success in all these businesses, Levy reveals, is its engineering mind-set and adoption of such Internet values as speed, openness, experimentation, and risk taking. After its unapologetically elitist approach to hiring, Google pampers its engineers—free food and dry cleaning, on-site doctors and masseuses—and gives them all the resources they need to succeed. Even today, with a workforce of more than 23,000, Larry Page signs off on every hire.But has Google lost its innovative edge? With its newest initiative, social networking, Google is chasing a successful competitor for the first time. Some employees are leaving the company for smaller, nimbler start-ups. Can the company that famously decided not to be evil still compete?No other book has ever turned Google inside out as Levy does with In the Plex.

    More and more leading businesses today use estimation questions in interviews to test applicants' abilities to think on their feet. Guesstimation enables anyone with basic math and science skills to estimate virtually anything--quickly--using plausible assumptions and elementary arithmetic.Lawrence Weinstein and John Adam present an eclectic array of estimation problems that range from devilishly simple to quite sophisticated and from serious real-world concerns to downright silly ones. How long would it take a running faucet to fill the inverted dome of the Capitol? What is the total length of all the pickles consumed in the US in one year? What are the relative merits of internal-combustion and electric cars, of coal and nuclear energy? The problems are marvelously diverse, yet the skills to solve them are the same. The authors show how easy it is to derive useful ballpark estimates by breaking complex problems into simpler, more manageable ones--and how there can be many paths to the right answer. The book is written in a question-and-answer format with lots of hints along the way. It includes a handy appendix summarizing the few formulas and basic science concepts needed, and its small size and French-fold design make it conveniently portable. Illustrated with humorous pen-and-ink sketches, Guesstimation will delight popular-math enthusiasts and is ideal for the classroom.

    For the most part the book is a discussion of good writing style and effective research strategies. Some of the material is accepted wisdom, some is controversial, and some is my opinions. Although the book is brief, it is designed to be comprehensive: some readers may be interested in exploring topics further, but for most readers this book should be suf?cient. The ?rst edition of this book was almost entirely about writing. This e- tion, partly in response to reader feedback and partly in response to issues that arose in my ownexperiences as an advisor, researcher, and referee, is also about research methods. Indeed, the two topics writing about and doing research are not clearly separated. It is a small step from asking how do I write? to askingwhatisitthatIwriteabout? As previously, the guidance on writing focuses on research, but much of the material is applicable to general technical and professional communication. Likewise, the guidance on the practice of research has broader lessons. A pr- titioner trying a new algorithm or explaining to colleagues why one solution is preferable to another should be con?dent that the arguments are built on robust foundations. And, while this edition has a stronger emphasis on research than did the ?rst, nothing has been deleted; there is additional material on research, but the guidance on writing has not been taken away."
