The phlogiston theory (from the Ancient Greek φλογιστόν phlogistón "burning up", from φλόξ phlóx "flame"), first stated in 1667 by Johann Joachim Becher, is an obsolete scientific theory that postulated the existence of a fire-like element called "phlogiston", which was contained within combustible bodies and released during combustion. The theory was an attempt to explain processes of burning such as combustion and the rusting of metals, which are now collectively known as oxidation.

Famous quotes containing the word theory:
“In the theory of gender I began from zero. There is no masculine power or privilege I did not covet. But slowly, step by step, decade by decade, I was forced to acknowledge that even a woman of abnormal will cannot escape her hormonal identity.”
—Camille Paglia (b. 1947)
