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.

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.

Mihajlo Pupin and Father Vasa Živković
Mihajlo Pupin and father Vasa Živković DRAGOLJUB A. CUCIĆ Regional centre for talents “Mihajlo Pupin”, Pančevo, Serbia, [email protected] Summary There is often a bond between two great men of a society at the time when one is at the peak of his life and the other at its beginning. The great Serbian 19th century poet, clergyman and educator father Vasa Živković, interceding in favour of his student Mihajlo Pupin, significantly influenced the conditions necessary for Pupin`s development into the person he later became. Mihajlo Pupin was certainly not the only student to benefit from father Vasa Živković advice and material support. However their relationship is a perfect example of an acclaimed person successfully influencing a person yet to win acclaim. Key words: Mihajlo Pupin, father Vasa Živković, Pančevo, secondary school1, parish, scholarship, Prague. Introduction Many books, studies and papers were written about Mihajlo Pupin and many national and international symposiums were dedicated to his life and work. Inspite of everything that was achieved in bringing to light Pupin`s life and work there are still insufficiently explored periods filled with important events and influences. The reason to adventure into this work is the educational character of discovering talent in the pupils and giving necessary support throughout the adversity of growing up. Many talents have disappeared in the everyday of life for the lack of support when it was most needed. Supporting the talented students does not ensure that their talent would be successfully developed. Many factors need be fulfilled before this is achieved: diligence, health, good fortune .. -
The Curious Case of U.S. Letters Patent No. 223,898
CHAPTER 5 The Curious Case of U.S. Letters Patent No. 223,898 I have not failed. I’ve just found ten thousand ways that don’t work. —Thomas Edison ho invented the light bulb? This was the topic at hand. Technically, the litigation Wwas between the Edison Electric Light Company and the Mount Morris Electric Light Company, but everyone knew that these were subsidiaries and legal proxies for their parent companies. Even the attorneys litigating this $1 billion case called it simply Edison v. Westinghouse. The issue before them: U.S. Letters Patent No. 223,898, granted to Thomas Edison on January 27, 1880, which described the invention of an “incandescent electric lamp.” Quickly nicknamed the Light Bulb Patent by the press, it was without question the most valuable patent ever granted in the history of the United States. And George Westinghouse was accused of infringing on it. Yet, as Paul Cravath pointed out to his client George Westinghouse, even a problem so simply put might yet admit to many layers of unraveling. In fact, the question hinged on one’s precise definition of the terms involved—“who,” “in- vented,” “the,” and, most importantly, “light bulb.” The first electric lamps had actually been invented almost a cen- tury before, Paul had learned when he’d first begun to research the case. Sir Humphry Davy had publicly demonstrated early “arc lights” in 1809. By attaching a battery to two charcoal sticks, he’d caused a U-shaped thread of electricity to “arc” across the gap between the sticks. The explosion of light was blindingly bright; perfect for light- ing dark outdoor areas, if it could be tamed into safety and reliability. -
