He emigrated in 1884 to the United States, where he became a naturalized citizen. He worked for a short time at the Edison Machine Works in New York City before he struck out on his own. With the help of partners to finance and market his ideas, Tesla set up laboratories and companies in New York to develop a range of electrical and mechanical devices. His alternating current (AC) induction motor and related polyphase AC patents, licensed by Westinghouse Electric in 1888, earned him a considerable amount of money and became the cornerstone of the polyphase system which that company eventually marketed. -

Tribute to a Genius: the Electrifying Legacy of Nikola Tesla Cleveland Plain Dealer May 17, 2006
Tribute to a Genius: The electrifying legacy of Nikola Tesla Cleveland Plain Dealer May 17, 2006 With preparations under way to commemorate the 150th anniversary of Nikola Tesla's birth, members of the Serbian-American community are heartened that their Balkan countryman is gaining widespread recognition as one of the greatest pioneers in the history of electrical science. On June 4, a tribute to Tesla will be held at St. Sava Serbian Orthodox Cathedral in Parma. Organized by Paul Cosic, a Serbian-American businessman, the event is open to the public and includes a memorial service, followed by a banquet at 1 p.m. The keynote speaker will be Professor Jasmina Vujic, the chair of the department of nuclear engineering at the University of California, Berkeley. Tesla, the son of a Serbian Orthodox priest, was born July 10, 1856, in what is now the Republic of Croatia. A physicist, mechanical engineer and electrical engineer, Tesla migrated to the United States in 1884 at age 28. Over the next six decades, he was responsible for numerous inventions relating to radio devices, electrical transmission and electrical motors. Tesla held dozens of basic U.S. patents for his poly-phase alternating current (AC) system of generators, motors and transformers, which eventually supplanted Thomas Edison's direct current (DC) system. Along with his impact on modern technology, Tesla also was an influence on generations of aspiring engineers, particularly in his homeland. "From an early age, he was kind of my hero," says the Serbian-born Vujic, who is the first woman to lead a nuclear engineering program at a U.S. -
Thomas Edison Vs Nikola Tesla THOMAS EDISON VS NIKOLA TESLA
M C SCIENTIFIC RIVALRIES PHERSON AND SCANDALS In the early 1880s, only a few wealthy people had electric lighting in their homes. Everyone else had to use more dangerous lighting, such as gas lamps. Eager companies wanted to be the first to supply electricity to more Americans. The early providers would set the standards—and reap great profits. Inventor THOMAS EDISON already had a leading role in the industry: he had in- vented the fi rst reliable electrical lightbulb. By 1882 his Edison Electric Light Company was distributing electricity using a system called direct current, or DC. But an inventor named NIKOLA TESLA challenged Edison. Tesla believed that an alternating cur- CURRENTS THE OF rent—or AC—system would be better. With an AC system, one power station could deliver electricity across many miles, compared to only about one mile for DC. Each inventor had his backers. Business tycoon George Westinghouse put his money behind Tesla and built AC power stations. Meanwhile, Edison and his DC backers said that AC could easily electrocute people. Edison believed this risk would sway public opinion toward DC power. The battle over which system would become standard became known as the War of the Currents. This book tells the story of that war and the ways in which both kinds of electric power changed the world.

Rotating Magnetic Field in Induction Motor
Rotating Magnetic Field in AC Machines 1 Introduction In a DC machine, the stator winding is excited by DC current and hence the field produced by this wind- ing is time invariant in nature. In this machine the conversion of energy from electrical to mechanical form or vice versa is possible by one of the following ways: 1. rotating the rotor in the field produced by the stator 2. feeding external dc current through carbon brushes to the rotor 2 Pre-lab questions Let, XX = Last two digits of your roll number g1(t) = cos(!t) and g2(t; θ) = cos(!t) cos(θ) 1. Take ! = 2πf, where f = XX × 50. Vary !t from 0 to 2π. Plot g1(t) vs t using MATLAB (or any other suitable software) 2. Take ! = 2πf, where f = XX × 50. Vary !t from 0 to 2π. Take θ = 0 to 2π. Plot g2(t; θ) vs t; for θ = XX Plot g2(t; θ) vs θ; for !t = 0; π=4; π=2; 2π=3 3 Theory Now consider three coils A, B and C of N turns each, displaced in space by 120◦ and connected to a balanced 3 phase system as shown in Fig. 1. (Note that the stator winding of 3 phase induction machine is distributed in a large number of slots as shown in Fig. 2). The expressions for the current Figure 1: Coil arrangement to produce rotating magnetic field 1 drawn by these coils are given by: ia = I sin(!st) o ib = I sin(!st + 120 ) (1) o ic = I sin(!st + 240 ) where !s = 2πF1 is supply frequency in rad/s and F1 is supply frequency in Hertz. -

Andrew May Pseudoscience and Science Fiction Science and Fiction Editorial Board Mark Alpert Philip Ball Gregory Benford Michael Brotherton Victor Callaghan Amnon H Eden Nick Kanas Geoffrey Landis Rudi Rucker Dirk Schulze-Makuch Ru€diger Vaas Ulrich Walter Stephen Webb Science and Fiction – A Springer Series This collection of entertaining and thought-provoking books will appeal equally to science buffs, scientists and science-fiction fans. It was born out of the recognition that scientific discovery and the creation of plausible fictional scenarios are often two sides of the same coin. Each relies on an understanding of the way the world works, coupled with the imaginative ability to invent new or alternative explanations—and even other worlds. Authored by practicing scientists as well as writers of hard science fiction, these books explore and exploit the borderlands between accepted science and its fictional counterpart. Uncovering mutual influences, promoting fruitful interaction, narrating and analyzing fictional scenarios, together they serve as a reaction vessel for inspired new ideas in science, technology, and beyond. Whether fiction, fact, or forever undecidable: the Springer Series “Science and Fiction” intends to go where no one has gone before! Its largely non-technical books take several different approaches. Journey with their authors as they • Indulge in science speculation—describing intriguing, plausible yet unproven ideas; • Exploit science fiction for educational purposes and as a means of promoting critical thinking; • Explore the interplay of science and science fiction—throughout the history of the genre and looking ahead; • Delve into related topics including, but not limited to: science as a creative process, the limits of science, interplay of literature and knowledge; • Tell fictional short stories built around well-defined scientific ideas, with a supplement summarizing the science underlying the plot. -
Chronicles of Mechanical Engineering in the United States
From the time it was organized in 1880, the American Society of Mechanical Engineers recorded aspects of the history of the mechanical engineering profession and the careers of some of its notable practitioners. The Society’s CHRONICLES OF historical efforts were formalized in 1971 with the creation of a History and Heritage Committee. This volume commemorates the fiftieth anniversary of the formation of that committee and collects, in a single place, many of the historical contributions published over the past fifty years in ASME’s flagship journal Mechanical Engineering. In preparation for the United States’ bicentennial year, and later the Society’s centennial, the editors of Mechanical Engineering contracted with engineer-historian Fritz Hirschfeld for a long series of articles about the county’s early mechanical engineering heritage and the lives of notable mechanical engineers, particularly those associated with ASME’s founding. Hirschfeld’s articles form the foundation of this volume. To supplement Hirschfeld’s work, the editors have added numerous other historical articles published in Mechanical Engineering. The engineering innovations described by these articles have been enormously important to the development of modern technological society, and the stories behind their development should be of interest to engineers interested in the history of their profession, as well as anyone interested in American Downloaded from http://asmedigitalcollection.asme.org/ebooks/book/chapter-pdf/6715821/356056_fm.pdf by guest on 05 August 2021 history.

HOWEVER, due to the fact that the 1969 text is no longer in publication, complicated by the fact that these copies are forty-four (44) years old and in a very fragile condition, this PDF version of the text was created for student use in the Department of Mathematics and Science. - Professor Charles Rubenstein, January 2013 Man of High Fidelity: Edwin Howard Armstrong EDWIN HOWARD ARMSTRONG Was the last – and perhaps the least known – of the great American Inventors. Without his major contributions, the broadcasting industry would not be what it is today, and there would be no FM radio. But in time of mushrooming industry and mammoth corporations, the recognition of individual genius is often refused, and always minimized. This is the extraordinary true story of the discovery of high fidelity, the brilliant man and his devoted wife who battled against tremendous odds to have it adopted, and their long fight against the corporations that challenged their right to the credit and rewards. Mrs. Armstrong finally ensured that right nearly ten years after her husband’s death.

Tesla's Polyphase System and Induction Motor
SERBIAN JOURNAL OF ELECTRICAL ENGINEERING Vol. 3, No. 2, November 2006, 121-130 Tesla’s Polyphase System and Induction Motor Petar Miljanić1 1 Introduction While new scientific knowledge is acquired by learning, observation, experiments and thinking, the inventions are mostly the fruit of the intuition of individuals and of their creative impulses. Inventors are people who use consciously or unconsciously the accumulated human knowledge and experi- ence, and find useful solutions for the humanity. Some of those inventions are epochal, like for instance the inventions of the steam and the internal combustion engine. These epochal inventions obviously include the Tesla’s system of poly- phase alternate currents and Tesla’s induction motor. It can be often heard that in some eras of civilization there appear needs and there ripen circumstances for the appearance of great inventions. The sequence of the human acquisition of knowledge of natural phenomena on which the function of the induction motor is based, and the sequence of experiments in the attempt to make the induction motor show that that opinion is not without basis. In the following lines, we will tell the story of the induction motor. That story will not be limited to Tesla’s key contribution only, but it will mention things that happened before and after Tesla’s patent applications by the end of 1887. 2 Discoveries The induction motor rotates thanks to the natural phenomenon which may be described by the following words: the moving magnetic field of one part of the motor, for instance the stator, induces currents in the conducting parts of another part of the motor, the rotor.
