and no aeroplane will ever be practically successful." A statement falsely attributed to Kelvin is: "There is nothing new to be discovered in physics now. All that remains is more and more precise measurement." This has been widely misattributed to Kelvin since the 1980s, either without citation or stating that it was made in an address to the British Association for the Advancement of Science (1900). There is no evidence that Kelvin said this, and the quote is instead a paraphrase of Albert A. Michelson, who in 1894 stated: "… it seems probable that most of the grand underlying principles have been firmly established … An eminent physicist remarked that the future truths of physical science are to be looked for in the sixth place of decimals." Similar statements were given earlier by others, such as Philipp von Jolly. The attribution to Kelvin in 1900 is presumably a confusion with his "Two clouds" speech, delivered to the Royal Institution in 1900 (see above), and which on the contrary pointed out areas that would subsequently see revolutions. In 1898, Kelvin predicted that only 400 years of oxygen supply remained on the planet, due to the rate of burning combustibles. In his calculation, Kelvin assumed that photosynthesis was the only source of free oxygen; he did not know all of the components of the oxygen cycle. He could not even have known all of the sources of photosynthesis: for example the cyanobacterium Prochlorococcus—which accounts for more than half of marine photosynthesis—was not discovered until 1986. Eponyms A variety of physical phenomena and concepts with which Thomson is associated are named Kelvin, including: Kelvin bridge (also known as Thomson bridge) Kelvin functions Kelvin–Helmholtz instability Kelvin–Helmholtz luminosity Kelvin–Helmholtz mechanism Kelvin material Joule–Kelvin effect Kelvin sensing Kelvin transform in potential theory Kelvin water dropper Kelvin wave Kelvin’s heat death paradox Kelvin's circulation theorem Kelvin–Stokes theorem Kelvin–Varley divider The SI unit of temperature, kelvin Mount Kelvin in New Zealand's Paparoa Range was named after him by the botanist William Trownson.
