This is an account of the author's investigation, on behalf of the Canadian government, into the life and ideas of the eccentric genius Nikola Tesla. This is a completely revised and redesigned edition, with a new introduction by the former head of the Tesla Museum, a new chapter and a selection of photographs of Tesla and his work in search of the holy grail of electricity - the transmission of power without loss. As a student in Prague in the 1870s, Tesla "saw" the electric induction motor and patented his discovery, -the first of many inventions whose plans seem to have come to him fully fledged. He worked for the Edison company in Paris before emigrating to the US and battling with Thomas Edison himself to ensure that alternating, rather than direct current, became the standard. He sold his patent in the induction motor for $1 million dollars to George Westinghouse, who used this system for the Niagara Falls Power Project. Moving to Colorado Springs, Tesla worked on resonance, building enormous oscillating towers in experiments which still intrigue today. In later life Tesla became a recluse, bombarding newspapers with eccentric claims, including energy transmissions to other planets. Though he died alone and virtually forgotten, rumours gradually grew that Tesla had made further remarkable discoveries. In an attempt to replicate his experiments, people still build Tesla towers and puzzle over the possible link with low-frequency broadcasts which can supposedly disrupt the weather and affect the human mind.

Elgar Advanced Introductions are stimulating and thoughtful introductions to major fields in the social sciences and law, expertly written by the world's leading scholars. Designed to be accessible yet rigorous, they offer concise and lucid surveys of the substantive and policy issues associated with discrete subject areas. This cutting edge book introduces the origins and consequences of digital platforms, examining how artificial intelligence-enabled digital platforms collect and process data from and about users by providing social media and e-commerce services. Robin Mansell and W. Edward Steinmueller compare and contrast neoclassical, institutional and critical political economy approaches. They show how uneven power relationships between platform operators and their users are analysed in different economic traditions. Key features include: analysis of economic and public values provides a foundation for platform regulation examines the impacts of platforms on the media industry challenges claims of the inevitability of platform dominance discusses key challenges, including: artificial intelligence, data sharing and competition in the digital economy. This concise book will be indispensable for advanced undergraduate and postgraduate students of media and communication studies, innovation studies and economics, particularly those focusing on platform economics.

'Witty, approachable and captivating' - Robin Ince 'A fascinating exploration of how we learned what matter really is' - Sean Carroll 'A delightfully fresh and accessible approach to one of the great quests of science' - Graham Farmelo 'Lays out not just what we know, but how we found out (and what is left to be discovered' - Katie Mack 'If you wish to make an apple pie from scratch, you must first invent the universe' - Carl Sagan Inspired by Sagan's famous line, How To Make An Apple Pie From Scratch sets out on a journey to unearth everything we know about our universe: how it started, how we found out, and what we still have left to discover. Will we ever be able to understand the very first moments of the world we inhabit? What is matter really made of? How did anything survive the fearsome heat of the Big Bang? In pursuit of answers, we meet the scientists, astronomers and philosophers who brought us to our present understanding of the world - offering readers a front-row seat to the most dramatic journey human beings have ever embarked on. Harry Cliff's How To Make An Apple Pie From Scratch is an essential, fresh and funny guide to how we got to where we are now - and what we have to come.

This book covers thirty years of the Leningrad Mathematical Olympiad, which was, ostensibly, the very first formally organized, open, official city-level mathematical contest in the world. Founded in 1934 by a group of dedicated Soviet mathematicians, it played an outstanding (and often underappreciated) role in creating the Leningrad (St. Petersburg) school of mathematics of the 20th century.The book begins with the extensive introduction containing two prefaces (one of them written specifically for this edition), a large historical survey of the Leningrad Mathematical Olympiad, a section describing the logistical side of the contest, and a small chapter dedicated to the very first Mathematical Olympiad held in 1934, whose problems were recently found in the Soviet-era library archives.The main text contains approximately 1,100 highly original questions for students of grades 5 through 10 (ages 11-12 through 17-18) offered at the two concluding rounds of the Leningrad City Mathematics Olympiads in the years of 1961-1991. Full solutions, hints and answers are provided for all questions with very rare exceptions.It also includes 120 additional questions, offered at the various mathematical contests held in Leningrad over the same thirty-year period — on average, their difficulty is somewhat higher than that of the regular Mathematical Olympiad problems.
