Galton board (W3)
Engl. "Quincunx" geht zurück auf lat. "quincunx" = dt. "fünf Zwölftel" setzt sich zusammen aus lat. "quinque" = dt. "fünf" und lat. "uncia" = dt. "1 Unze" = "5/12 As" ("quinque uncio") (Münze). Als Bezeichnung für ein Hohlmaß war es "5/12 sextarius" = "0,225 l".Beim Würfeln mit 2 Würfeln entsprach eine 5 auch "ein zwölftel" der möglichen Gesamtpunktzahl. Dies führte wohl dazu, dass auch die 5 Punkte auf einem Würfel als "Quincunx" bezeichnet wurden und wo die Art der Anordnung, die Kreuzstellung z.B. bei Anpflanzungen oder bei der Anordnung von Säulen zu finden ist (:·: oder in längerer Anodnung :·:·:·:·:·:·:) (z.B. im Tempel Angkor Vat in der Ruinenstadt in Kambodscha), spricht man ebenfalls von "Quincunx". 5/12 eines Kreises 360*5/12 sind 150° und in diesem Sinne wird es auch in der Astrologie für den Winkelabstand zwischen den Planeten benutzt.
Und das im deutschsprachigen Raum als "Galtonbrett" (engl. "Galton's Board", nach Sir Francis Galton, 1890, Naturforscher, Mediziner, 16.02.1822 (Birmingham) - 17.01.1911 (London)) bezeichnete Experimentierbrett für die Gauss'che Normalverteilung wird auch engl. "Quincunx" genannt, wegen der Anordnung der Stifte an denen sich eine herunterrollende Kugel für lings oder rechts entscheiden muß.
Die Bezeichnung bot. "Galtonia" geht ebenfalls auf Sir Francis Galton, der sich auch als Afrikaforscher einen Namen machte.

It would be more appropriate to call our applet Galton's board or a quincunx board, however this is far more difficult to pronounce.

Galton's Board or Quincunx
This applet simulates Galton's Board, in which balls are dropped through a triangular array of nails. This device is also called a quincunx. Every time a ball hits a nail it has a probability of 50 percent to fall to the left of the nail and a probability of 50 percent to fall to the right of the nail.
