Napoleon, informed of his works, summoned him in 1801 for a command performance of his experiments. [200] In 1967, Steven Weinberg[201] and Abdus Salam[202] incorporated the Higgs mechanism[203][204][205] into Glashow's electroweak theory, giving it its modern form. The first usage of the word electricity is ascribed to Sir Thomas Browne in his 1646 work, Pseudodoxia Epidemica. Faradays case is not common in the history of physics: although his training was very basic, the laws of electricity and magnetism are due much more to Faradays experimental discoveries than to any other scientist. brainly.ph/question/250553, What is an electromagnetic wave? On the reception of relativity theory around the world, and the different controversies it encountered, see the articles in Thomas F. Glick, ed.. Lise Meitner and O.R. Frisch. 4. He Bellis, Mary. Franklin also documented the conservation of charge, the theory that an isolated system has a constant total charge. Michael Faraday wrote in the preface to his Experimental Researches, relative to the question of whether metallic contact is productive of a part of the electricity of the voltaic pile: "I see no reason as yet to alter the opinion I have given; but the point itself is of such great importance that I intend at the first opportunity renewing the inquiry, and, if I can, rendering the proofs either on the one side or the other, undeniable to all. The collector, consisting of a series of metal points, was added to the machine by Benjamin Wilson about 1746, and in 1762, John Canton of England (also the inventor of the first pith-ball electroscope in 1754[37]) improved the efficiency of electric machines by sprinkling an amalgam of tin over the surface of the rubber. It was also the direct ancestor of electric motors, for it was only necessary to reverse the situation, to feed an electric current to the disk, to make it rotate. "Joseph Henry." [23], The magnetic needle compass was developed in the 11th century and it improved the accuracy of navigation by employing the astronomical concept of true north (Dream Pool Essays, 1088). The Greeks noted that if they rubbed the amber for long enough they could even get an electric spark to jump.
