Hertz published his work in a book titled: Electric waves: being researches on the propagation of electric action with finite velocity through space. [134] The discovery of electromagnetic waves in space led to the development of radio in the closing years of the 19th century.
Michael Faraday (/ ˈ f ær ə d eɪ,-d i /; 22 September 1791 – 25 August 1867) was an English chemist and physicist who contributed to the study of electrochemistry and electromagnetism. His main discoveries include the principles underlying electromagnetic induction , diamagnetism and electrolysis .
This field emerged in the middle of the 18th century, following electrical researches and the discovery of the effects of electricity on the human body by scientists including Bertrand Bajon and Ramón M. Termeyer in the 1760s, [8] and by John Walsh [9] [10] and Hugh Williamson in the 1770s. [11] [12]
Heinrich Rudolf Hertz (/ h ɜːr t s /, HURTS; German: [ˈhaɪnʁɪç hɛʁts]; [1] [2] 22 February 1857 – 1 January 1894) was a German physicist who first conclusively proved the existence of the electromagnetic waves predicted by James Clerk Maxwell's equations of electromagnetism.
1873 – J. C. Maxwell publishes A Treatise on Electricity and Magnetism which states that light is an electromagnetic phenomenon. 1874 – German scientist Karl Ferdinand Braun discovers the "unilateral conduction" of crystals. [20] [21] Braun patents the first solid state diode, a crystal rectifier, in 1899. [22]
James Clerk Maxwell FRS FRSE (13 June 1831 – 5 November 1879) was a Scottish physicist and mathematician [1] who was responsible for the classical theory of electromagnetic radiation, which was the first theory to describe electricity, magnetism and light as different manifestations of the same phenomenon.
Using his newly developed electromagnetic principle, in 1831, Henry created one of the first machines to use electromagnetism for motion. This was the earliest ancestor of modern DC motor . It did not make use of rotating motion, but was merely an electromagnet perched on a pole, rocking back and forth.
The work of Principia by Newton, who also refined the scientific method, and who is widely regarded as the most important figure of the Scientific Revolution. [4] [5] Science (ancient) Thales (c. 624/623 – c. 548/545 BC) [6] [7] Attempted to explain natural phenomena without recourse to mythology
