Tornado Quotes (4 quotes)

HURRICANE, n. An atmospheric demonstration once very common but now generally abandoned for the tornado and cyclone. The hurricane is still in popular use in the West Indies and is preferred by certain old-fashioned sea-captains.
The Collected Works of Ambrose Bierce (1911), Vol. 7, The Devil's Dictionary,  143-144.

If the flap of a butterfly’s wings can be instrumental in generating a tornado, it can equally well be instrumental in preventing a tornado.
In talk presented at the 139th Annual Meeting in Washington, D.C. of the American Association for the Advancement of Science (29 Dec 1972). The text of the talk, in its original form, as then prepared for press release but unpublished, is in Edward Lorenz, Essence of Chaos (1995), Appendix 1, 181.

Partly because of improved technology, partly because of the pressures of inflation, partly from causes few understand or agree about, prices have soared. A Spitfire cost £5000 in 1940. A Tornado Air Defence Fighter costs £14 million today. That is a lot of inflation! And even when all has been said about the greater effectiveness of the latter machine, so that far fewer are needed, there still remains a mighty problem. There tend to be limits to the extent to which numbers can be reduced by superior quality. A ship can only cover a certain amount of ocean, however sophisticated it may be; and the most formidable of tanks can’t do much beyond the limits of its commander’s sight. There is a minimum numerical requirement, and meeting it with equipment capable of taking on the enemy was already, in 1955, a source of worry.
In Reflect on Things Past: The Memoirs of Lord Carrington (1089), 110.

Edward Lorenz quote: Predictability: Does the flap of a butterfly’s wings in Brazil set off a tornado in Texas?
Predictability: Does the flap of a butterfly’s wings in Brazil set off a tornado in Texas?
Title of paper presented at the 139th Annual Meeting in Washington, D.C. of the American Association for the Advancement of Science (29 Dec 1972). The text of the talk, in its original form, as then prepared for press release but unpublished, is in Edward Lorenz, Essence of Chaos (1995), Appendix 1, 181. Note: Webmaster has been unable to find a verbatim source for a widely circulated variant, namely: The fluttering of a butterfly’s wing in Rio de Janeiro, amplified by atmospheric currents, could cause a tornado in Texas two weeks later. That form is given in Laura Nader, Naked Science: Anthropological Inquiry Into Boundaries (1996), 209. However, it appears in a sentence as narrative, without quotation marks, and has no citation. Webmaster believes it may be the concept restated by Nader in her own words. Webmaster has not yet found any earlier printed, cited or verbatim example in the wording of the variant. If you know a primary source for this variant, please contact Webmaster.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
