Predictability: Does the flap of a butterflys 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 The text of the talk, in its original form, as then prepared for press release but unpublished, is in Edward Lorenz, Essence of Chaos (1995), Appendix 1, 181.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 butterflys 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.
Who then can calculate the path of the molecule? how do we know that the creations of worlds are not determined by the fall of grains of sand?
Victor Hugo and Charles E. Wilbour (trans.), Les Misιrables (1862), 41.
