Edison's method was to invent systems rather than components of systems. Edison did not just invent a light bulb, he invented an economically viable system of lighting including its generators, cables, metering and so on. Edison invented by repeatedly trying devices in more complex environments to progressively approximate their final use ...
The Big Bang theory was confirmed in 1929 by the American astronomer Edwin Hubble's analysis of galactic redshifts. [63] But the Big Bang theory had been presaged three-quarters of a century earlier in the American poet and short-story writer Edgar Allan Poe's then much-derided essay, Eureka: A Prose Poem (1848).

The quantum theory was needed to explain effects even with visual light that Maxwell's classical theory could not (such as spectral lines). Quantum theory In 1900 Max Planck , attempting to explain black-body radiation , suggested that although light was a wave, these waves could gain or lose energy only in finite amounts related to their ...
1878 – Thomas Edison, following work on a "multiplex telegraph" system and the phonograph, invents an improved incandescent light bulb. This was not the first electric light bulb but the first commercially practical incandescent light. In 1879 he produces a high-resistance lamp in a very high vacuum; the lamp lasts hundreds of hours. While ...
1835 James Bowman Lindsay demonstrates a light bulb based electric lighting system to the citizens of Dundee. 1841 Arc-lighting is used as experimental public lighting in Paris. 1853 Ignacy Łukasiewicz invents the modern kerosene lamp. 1856 glassblower Heinrich Geissler confines the electric arc in a Geissler tube.
Alexander Nikolayevich Lodygin, known after immigration to US as Alexandre de Lodyguine (Russian: Александр Николаевич Лодыгин; October 6, 1847 – March 16, 1923) was a Russian electrical engineer and inventor, one of the inventors of the incandescent light bulb.

its predecessors like the theories of luminiferous aether, its early competitors, i.e.: Ritz’s ballistic theory of light, the models of electromagnetic mass created by Abraham (1902), Lorentz (1904), Bucherer (1904) and Langevin (1904). This list also mentions the origins of standard notation (like c) and terminology (like theory of relavity).
