Using old bottles and lumber, he made a crude electrostatic generator and did simple experiments. 5, 2023, thoughtco.com/james-clerk-maxwell-inventor-1991689. London: C. and R. Baldwin. E {\displaystyle m=E/c^{2}} The good contrast it provides between the different soft tissues of the body make it especially useful in brain, muscles, heart, and cancer compared with other medical imaging techniques such as computed tomography (CT) or X-rays. In 1887, the German physicist Heinrich Hertz in a series of experiments proved the actual existence of electromagnetic waves, showing that transverse free space electromagnetic waves can travel over some distance as predicted by Maxwell and Faraday. In 1947, while he was traveling by train to reach Schenectady from New York,[180] after giving a talk at the conference at Shelter Island on the subject, Bethe completed the first non-relativistic computation of the shift of the lines of the hydrogen atom as measured by Lamb and Retherford. [36] Experiments with the electric machine were largely aided by the discovery that a glass plate, coated on both sides with tinfoil, would accumulate electric charge when connected with a source of electromotive force. "James Clerk Maxwell, Master of Electromagnetism." He provided the experimental, and a good deal of the theoretical, foundation upon which James Clerk Maxwell erected classical electromagnetic field theory. It took a bit longer for scientists to discover the higher-energy (shorter wavelength) light in the electromagnetic spectrum. Davy concluded that this gas was an element, to which he gave the name chlorine, and that there was no oxygen whatsoever in muriatic acid. Although little of major importance was added to electromagnetic theory in the 19th century after Maxwell, the discovery of the electron in 1898 opened up an entirely new area of study: the nature of electric charge and of matter itself. Gamma-rays were first observed in 1900 by Paul Villard when he was Rugbyc. II, Chap.
