Michael Faraday – fizyk i chemik angielski, eksperymentator, samouk. Profesor Instytutu Królewskiego i Uniwersytetu Oksfordzkiego, członek Royal Society, w młodości asystent H.B. Davy’ego.

Największe znaczenie miały prace Faradaya dotyczące elektryczności. W 1831 r. odkrył zjawisko indukcji elektromagnetycznej, co przyczyniło się do powstania elektrodynamiki. W latach 1833-1834 sformułował prawa elektrolizy i wprowadził nomenklaturę dla opisu tego zjawiska.

Stworzył podstawy elektrochemii. Faraday odkrył również zjawisko samoindukcji, zbudował pierwszy model silnika elektrycznego. W 1845 r. stwierdził, że diamagnetyzm jest powszechną właściwością materii, odkryty zaś przez niego paramagnetyzm – właściwością szczególną niektórych jej rodzajów. Faraday wprowadził pojęcie linii sił pola i wysunął twierdzenie, że ładunki elektryczne działają na siebie za pomocą takiego pola. W 1848 r. odkrył zjawisko magnetooptyczne.

W 1825 roku odkrył benzen, wydzielił naftalen, heksachloroetan, koloidalne złoto. Był też twórcą prostej metody skraplania gazów.

Prowadził pionierskie prace nad stalami stopowymi i szkłem optycznym. Stwierdził katalityczne działanie światła w reakcjach chlorowców na węglowodory .

2 czerwca 1821 ożenił się z Sarą Barnard; związek był bezdzietny. Faraday był członkiem sandemanianów

„Nothing is too wonderful to be true, if it be consistent with the laws of nature“

— Michael Faraday
Context: ALL THIS IS A DREAM. Still examine it by a few experiments. Nothing is too wonderful to be true, if it be consistent with the laws of nature; and in such things as these, experiment is the best test of such consistency. Laboratory journal entry #10,040 (19 March 1849); published in The Life and Letters of Faraday (1870) Vol. II, edited by Henry Bence Jones https://archive.org/stream/lifelettersoffar02joneiala#page/248/mode/2up/search/wonderful,p.248.This has sometimes been quoted partially as "Nothing is too wonderful to be true," and can be seen engraved above the doorway of the south entrance to the Humanities Building at UCLA in Los Angeles, California. http://lit250v.library.ucla.edu/islandora/object/edu.ucla.library.universityArchives.historicPhotographs%3A67

„Among those points of self-education which take up the form of mental discipline, there is one of great importance, and, moreover, difficult to deal with, because it involves an internal conflict, and equally touches our vanity and our ease. It consists in the tendency to deceive ourselves regarding all we wish for, and the necessity of resistance to these desires.“

Context: Among those points of self-education which take up the form of mental discipline, there is one of great importance, and, moreover, difficult to deal with, because it involves an internal conflict, and equally touches our vanity and our ease. It consists in the tendency to deceive ourselves regarding all we wish for, and the necessity of resistance to these desires. It is impossible for any one who has not been constrained, by the course of his occupation and thoughts, to a habit of continual self-correction, to be aware of the amount of error in relation to judgment arising from this tendency. The force of the temptation which urges us to seek for such evidence and appearances as are in favour of our desires, and to disregard those which oppose them, is wonderfully great. In this respect we are all, more or less, active promoters of error. In place of practising wholesome self-abnegation, we ever make the wish the father to the thought: we receive as friendly that which agrees with, we resist with dislike that which opposes us; whereas the very reverse is required by every dictate of common sense. Royal Institution Lecture On Mental Education (6 May 1854), as reprinted in Experimental Researches in Chemistry and Physics, by Michael Faraday, 1859, pp 474-475, emphasis verbatim.

„I have far more confidence in the one man who works mentally and bodily at a matter than in the six who merely talk about it“

— Michael Faraday
Context: I have far more confidence in the one man who works mentally and bodily at a matter than in the six who merely talk about it — and I therefore hope and am fully persuaded that you are working. Nature is our kindest friend and best critic in experimental science if we only allow her intimations to fall unbiased on our minds. Nothing is so good as an experiment which, whilst it sets an error right, gives us (as a reward for our humility in being reproved) an absolute advancement in knowledge. Letter to John Tyndall (19 April 1851); letter 2411, edited by

„Bacon in his instruction tells us that the scientific student ought not to be as the ant, who gathers merely, nor as the spider who spins from her own bowels, but rather as the bee who both gathers and produces.“

— Michael Faraday
Context: Bacon in his instruction tells us that the scientific student ought not to be as the ant, who gathers merely, nor as the spider who spins from her own bowels, but rather as the bee who both gathers and produces. All this is true of the teaching afforded by any part of physical science. Electricity is often called wonderful, beautiful; but it is so only in common with the other forces of nature. The beauty of electricity or of any other force is not that the power is mysterious, and unexpected, touching every sense at unawares in turn, but that it is under law, and that the taught intellect can even now govern it largely. The human mind is placed above, and not beneath it, and it is in such a point of view that the mental education afforded by science is rendered super-eminent in dignity, in practical application and utility; for by enabling the mind to apply the natural power through law, it conveys the gifts of God to man. Lecture notes of 1858, quoted in The Life and Letters of Faraday (1870) by Bence Jones, Vol. 2, p. 404
