In the history of chemistry, fire air was postulated to be one of two fluids of common air. This theory was positioned in 1775 by Swedish chemist Carl Wilhelm Scheele. In Scheele’s Chemical Treatise on Air and Fire he states: “air is composed of two fluids, differing from each other, the one of which does not manifest in the least the property of attracting phlogiston, whilst the other, which composes between the third and forth part of the whole mass of the air, is peculiarly disposed to such attraction.” These two constituents of common air Scheele called Foul Air (“verdorbene Luft”) and Fire Air (“Feuerluft”); afterwards these components came to be known as nitrogen and oxygen, respectively.
Famous quotes containing the words fire and/or air:
“Can fire be carried in the bosom without burning one’s clothes? Or can one walk on hot coals without scorching the feet? So is he who sleeps with his neighbor’s wife; no one who touches her will go unpunished.”
—Bible: Hebrew, Proverbs 6:27-29.
“If when a businessman speaks of minority employment, or air pollution, or poverty, he speaks in the language of a certified public accountant analyzing a corporate balance sheet, who is to know that he understands the human problems behind the statistical ones? If the businessman would stop talking like a computer printout or a page from the corporate annual report, other people would stop thinking he had a cash register for a heart. It is as simple as that—but that isn’t simple.”
—Louis B. Lundborg (1906–1981)
