Sir John Leslie (10 April 1766 – 3 November 1832) was a Scottish mathematician and physicist best remembered for his research into heat. Leslie gave the first modern account of capillary action in 1802 and froze water using an air-pump in 1810, the first artificial production of ice. In 1804, he experimented with radiant heat using a cubical vessel filled with boiling water. One side of the cube is composed of highly polished metal, two of dull metal (copper) and one side painted black. He showed that radiation was greatest from the black side and negligible from the polished side. The apparatus is known as a Leslie cube. ==Early life== Leslie was born of humble parentage at Largo in Fife and received his early education there and at Leven. In his thirteenth year, encouraged by friends who had even then remarked his aptitude for mathematical and physical science, he entered the University of St Andrews. On the completion of his arts course, he nominally studied divinity at Edinburgh until 1787. From 1788–1789 he spent rather more than a year as private tutor in a Virginian family, and from 1791 till the close of 1792 he held a similar appointment at Etruria, Staffordshire, with the family of Josiah Wedgwood, employing his spare time in experimental research and in preparing a translation of Buffon's ''Natural History of Birds'', which was published in nine volumes in 1793, which brought him money. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「John Leslie (physicist)」の詳細全文を読む スポンサード リンク
