Book Description
François Arago, the first to show in 1810 that the surface of the Sun and stars is made of incandescent gas and not solid or liquid, was a prominent physicist of the 19th century. He used his considerable influence to help Fresnel, Ampere and others develop their ideas and make themselves known. This book covers his personal contributions to physics, astronomy, geodesy and oceanography, which are far from negligible, but insufficiently known. Arago was also an important and influential political man who, for example, abolished slavery in the French colonies. One of the last humanists, he had a very broad culture and range of interests. In parallel to his biography, this title also covers the spectacular progresses of science at the time of Arago, especially in France: the birth of physical optics, electromagnetism and thermodynamics. Francois Arago’s life is a fascinating epic tale that reads as a novel.

Book Description
Ce livre historique peut contenir de nombreuses coquilles et du texte manquant. Les acheteurs peuvent generalement telecharger une copie gratuite scannee du livre original (sans les coquilles) aupres de l'editeur. Non reference. Non illustre. 1865 edition. Extrait: ...il l'a circonscrite, ne produira pas ce resultat. Le gouvernement ne veut maintenant travailler qu'au chemin de Belgique; il n'y aurait donc qu'une partie de la population, celle du nord de la France qui verrait le gouvernement dans toute sa splendeur; au Midi, ce ne serait plus le gouvernement, mais des compagnies particulieres. Ainsi, ce motif ne devait pas etre bien puissant pour le gouvernement, puisqu'il y a renonce pour la plus grande partie des populations. Il y a une consideration qu'on a formulee en ces termes: Le gouvernement serait a la remorque des compagnies. Non, Messieurs, le gouvernement ferait ce que les compagnies ne font pas. II y a des chemins qui peuvent avoir une immense utilite nationale, et pour lesquels des compagnies ne se presentent pas, le gouvernement ferait ces lignes-la; de plus, le gouvernement fera d'autres travaux. Est-ce que nos routes ordinaires ne sont pas, sur plusieurs points, dans un etat deplorable? (Mouvements divers.) Je crois apercevoir une denegation (Tres-bien!) je citerai des faits, je citerai une route royale, une des routes qui conduisent a Londres, ou la diligence a ete obligee d'abandonner un grand bourg et de passer a travers des jardins, et cela pendant six mois! Je citerai la route de Chalons a Sainte-Menehould, ou il est presque impossible de voyager l'hiver. M. Perignon. Rien n'est plus vrai 1 M. Arago. Ou l'on est oblige d'atteler dix chevaux aux diligences, ou les voitures versent sans que les carreaux se brisent dans la boue, tant la route est liquide. M. Roul. La route de...

Book Description
Everything you think you know about Nikola Tesla is wrong. The Truth About Tesla sets the record straight. Nikola Tesla was one of the greatest electrical inventors who ever lived. For years, the engineering genius was relegated to relative obscurity, his contributions to humanity (we are told) obscured by a number of nineteenth-century inventors and industrialists who took credit for his work or stole his patents outright. In recent years, the historical record has been "corrected" and Tesla has been restored to his rightful place among historical luminaries like Thomas Edison, George Westinghouse, and Gugliemo Marconi. Most biographies repeat the familiar account of Tesla's life, including his invention of alternating current, his falling out with Edison, how he lost billions in patent royalties to Westinghouse, and his fight to prove that Marconi stole 13 of his patents to "invent" radio. But, what really happened? Consider this: Everything you think you know about Nikola Tesla is wrong. Newly uncovered information proves that the popular account of Tesla's life is itself very flawed. In The Truth About Tesla, Christopher Cooper sets out to prove that the conventional story not only oversimplifies history, it denies credit to some of the true inventors behind many of the groundbreaking technologies now attributed to Tesla and perpetuates a misunderstanding about the process of innovation itself. Are you positive that Alexander Graham Bell invented the telephone? Are you sure the Wright Brothers were the first in flight? Think again! With a provocative foreword by Tesla biographer Marc. J. Seifer, The Truth About Tesla is one of the first books to set the record straight, tracing the origin of some of the greatest electrical inventions to a coterie of colorful characters that conventional history has all but forgotten.
