翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Gauss's Pythagorean right triangle proposal ： ウィキペディア英語版 Gauss's Pythagorean right triangle proposal Gauss's Pythagorean right triangle proposal is an idea attributed to Carl Friedrich Gauss for a method to signal extraterrestrial beings by constructing an immense right triangle and three squares on the surface of the Earth. The shapes would be a symbolical representation of the Pythagorean theorem, large enough to be seen from the Moon or Mars. Although credited in numerous sources as originating with Gauss, with exact details of the proposal set out, the specificity of detail, and even whether Gauss made the proposal, have been called into question. Many of the earliest sources do not actually name Gauss as the originator, instead crediting a "German Astronomer" or using other nonspecific descriptors, and in some cases naming a different author entirely. The details of the proposal also change significantly upon different retellings. Nevertheless, Gauss's writings reveal a belief and interest in finding a method to contact extraterrestrial life, and that he did, at the least, propose using amplified light using a heliotrope, his own 1818 invention, to signal supposed inhabitants of the Moon. ==Proposal== Carl Friedrich Gauss is credited with an 1820 proposal for a method to signal extraterrestrial beings in the form of drawing an immense right triangle and three squares on the surface of the Earth, intended as a symbolical representation of the Pythagorean theorem, large enough to be seen from the Moon or Mars. Details vary across sources, but typically the "drawing" was to be constructed on the Siberian tundra, and made up of vast strips of pine forest forming the right triangle's borders, with the interior of the drawing and exterior squares composed of fields of wheat. Gauss is said to have been convinced that Mars harbored intelligent life and that this geometric figure, invoking the Pythagorean theorem through the squares on the outside borders (sometimes called a "windmill diagram," as originated by Euclid), would demonstrate to such alien observers the reciprocal existence of intelligent life on Earth and its grounding in mathematics. Wheat was said to be chosen by Gauss for contrast with the pine tree borders "because of its uniform color". 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「Gauss's Pythagorean right triangle proposal」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
