His inventions, patents, and theoretical work formed the basis of modern AC electricity, and contributed to the development of radio and television. Like his competitor Thomas Edison, Tesla was one of America's first celebrity scientists, enjoying the company of New York high society and dazzling the likes of Mark Twain with his electrical demonstrations. An astute self-promoter and gifted showman, he cultivated a public image of the eccentric genius. Even at the end of his life when he was living in poverty, Tesla still attracted reporters to his annual birthday interview, regaling them with claims that he had invented a particle-beam weapon capable of bringing down enemy aircraft.Plenty of biographies glamorize Tesla and his eccentricities, but until now none has carefully examined what, how, and why he invented. In this groundbreaking book, W. Bernard Carlson demystifies the legendary inventor, placing him within the cultural and technological context of his time, and focusing on his inventions themselves as well as the creation and maintenance of his celebrity. Drawing on original documents from Tesla's private and public life, Carlson shows how he was an idealist inventor who sought the perfect experimental realization of a great idea or principle, and who skillfully sold his inventions to the public through mythmaking and illusion.This major biography sheds new light on Tesla's visionary approach to invention and the business strategies behind his most important technological breakthroughs.

    New languages, new frameworks, new ways of doing things - a constant struggle just to stay current in the industry. This left no time to learn the foundational concepts and skills that come with a degree in Computer Science.

    While the scientist may identify problems, it falls to the engineer to solve them. It is the inherent practicality of engineering, which takes into account structural, economic, environmental, and other factors that science often does not consider, that makes engineering vital to answering our most urgent concerns. Henry Petroski takes us inside the research, development, and debates surrounding the most critical challenges of our time, exploring the feasibility of biofuels, the progress of battery-operated cars, and the question of nuclear power. He gives us an in-depth investigation of the various options for renewable energy--among them solar, wind, tidal, and ethanol--explaining the benefits and risks of each. Will windmills soon populate our landscape the way they did in previous centuries? Will synthetic trees, said to be more efficient at absorbing harmful carbon dioxide than real trees, soon dot our prairies? Will we construct a "sunshade" in outer space to protect ourselves from dangerous rays? In many cases, the technology already exists. What's needed is not so much invention as engineering. Just as the great achievements of centuries past--the steamship, the airplane, the moon landing--once seemed beyond reach, the solutions to the twenty-first century's problems await only a similar coordination of science and engineering. Eloquently reasoned and written, "The Essential Engineer" identifies and illuminates these problems--and, above all, sets out a course for putting ideas into action.

    The author shows how each manager must be a human resource problem solver. The tenth edition emphasises the most relevant and up-to-date practices.

    This book describes BEAM✲, an agile approach to dimensional modeling, for improving communication between data warehouse designers, BI stakeholders and the whole DW/BI development team. BEAM✲ provides tools and techniques that will encourage DW/BI designers and developers to move away from their keyboards and entity relationship based tools and model interactively with their colleagues. The result is everyone thinks dimensionally from the outset! Developers understand how to efficiently implement dimensional modeling solutions. Business stakeholders feel ownership of the data warehouse they have created, and can already imagine how they will use it to answer their business questions. Within this book, you will learn: ✲ Agile dimensional modeling using Business Event Analysis & Modeling (BEAM✲) ✲ Modelstorming: data modeling that is quicker, more inclusive, more productive, and frankly more fun! ✲ Telling dimensional data stories using the 7Ws (who, what, when, where, how many, why and how) ✲ Modeling by example not abstraction; using data story themes, not crow's feet, to describe detail ✲ Storyboarding the data warehouse to discover conformed dimensions and plan iterative development ✲ Visual modeling: sketching timelines, charts and grids to model complex process measurement - simply ✲ Agile design documentation: enhancing star schemas with BEAM✲ dimensional shorthand notation ✲ Solving difficult DW/BI performance and usability problems with proven dimensional design patterns Lawrence Corr is a data warehouse designer and educator. As Principal of DecisionOne Consulting, he helps clients to review and simplify their data warehouse designs, and advises vendors on visual data modeling techniques. He regularly teaches agile dimensional modeling courses worldwide and has taught dimensional DW/BI skills to thousands of students. Jim Stagnitto is a data warehouse and master data management architect specializing in the healthcare, financial services, and information service industries. He is the founder of the data warehousing and data mining consulting firm Llumino.

    The depth below is hot, much warmer than the surface and this book tunnels down through the geological layers, meeting the creatures that dwell in darkness, real and fictional -- rats and eels, monsters and ghosts. There is a bronze-age trackway under the Isle of Dogs, Wren found Anglo-Saxon graves under St Paul's, and the monastery of Whitefriars lies beneath Fleet Street. In Kensal Green cemetery there was a hydraulic device to lower bodies into the catacombs below -- "Welcome to the lower depths". A door in the plinth of statue of Boadicea on Westminster Bridge leads to a huge tunnel, packed with cables -- gas, water, telephone. When the Metropolitan Line was opened in 1864 the guards asked for permission to grow beards to protect themselves against the sulphurous fumes, and called their engines by the names of tyrants -- Czar, Kaiser, Mogul -- and even Pluto, god of the underworld.Going under London is to penetrate history, to enter a hidden world. "The vastness of the space, a second earth," writes Peter Ackroyd, "elicits sensations of wonder and of terror. It partakes of myth and dream in equal measure."

    In order to enable students to apply the basics of data modeling to real models, the book addresses the realities of developing systems in real-world situations by assessing the merits of a variety of possible solutions as well as using language and diagramming methods that represent industry practice.This revised edition has been given significantly expanded coverage and reorganized for greater reader comprehension even as it retains its distinctive hallmarks of readability and usefulness. Beginning with the basics, the book provides a thorough grounding in theory before guiding the reader through the various stages of applied data modeling and database design. Later chapters address advanced subjects, including business rules, data warehousing, enterprise-wide modeling and data management.

    Grant, arguing that the great Civil War commander’s battle to save the Union continued to the very end of his presidency when a crisis threatened to fracture the still fragile nation once again.In this follow-up to his acclaimed “Three Days” trilogy, Bret Baier’s To Rescue the Republic dramatically illuminates the life of one of America’s most consequential yet misunderstood leaders, Ulysses S. Grant, whose actions both as general and as president played an unparalleled role in preserving the United States.Born a tanner’s son in rugged Ohio in 1822 and battle-tested by the Mexican American War, Grant met his destiny on the bloody fields of the Civil War. His daring and resolve as a general gained the attention of President Lincoln, then desperate for bold leadership. Lincoln appointed Grant as Lieutenant General of the Union Army in March 1864. Within a year, Grant’s forces had seized Richmond and forced Robert E. Lee to surrender.Four years later, the reunified nation faced another leadership void after Lincoln’s assassination and an unworthy successor completed his term. Again, Grant answered the call. At stake once more was the future of the Union, for though the Southern states had been defeated, it remained to be seen if the former Confederacy could be reintegrated into the country—and if the Union could ensure the rights and welfare of African Americans in the South. Grant met the challenge by boldly advancing an agenda of Reconstruction and aggressively countering the Ku Klux Klan.  In his final weeks in the White House, however, Grant faced a crisis that threatened to undo his life’s work. The contested presidential election of 1876 produced no clear victory for either Republican Rutherford B. Hayes or Democrat Samuel Tilden, who carried most of the former Confederacy. Soon Southern states vowed to revolt if Tilden was not declared the victor. Grant was determined to use his influence to preserve the Union, establishing an electoral commission to peaceably settle the issue. Grant brokered a grand bargain: the installation of Republican Hayes to the presidency, with concessions to the Democrats that effectively ended Reconstruction. This painful compromise saved the nation, but tragically condemned the South to another century of civil-rights oppression.Deep with contemporary resonance and brimming with fresh detail that takes readers from the battlefields of the Civil War to the corridors of power where men decided the fate of the nation in back rooms, To Rescue the Republic reveals Grant, for all his complexity, to be among the first rank of American heroes.
