'''Werner Karl Heisenberg''' (December 5, 1901  – February 1, 1976)  was a [[German]] physicist and [[Nobel]] laureate (1932), most credited with the discovery of [[quantum mechanics]], in 1925. Heisenberg proposed that it is impossible to assign to an electron a position in space at a given time or follow it precisely in its orbit. Heisenberg thereby challenged the model of subatomic particles that was based on planetary orbits. Instead, Heisenberg suggested that mechanical quantities like position and velocity are better represented, not by ordinary [[commutative]] [[number]]s, but by non-commutative mathematical objects called [[matrix|matrices]]. He had this historic moment of [[insight]] in June 1925 while on the treeless island of Helgoland in the North Sea while sitting on a very large rock on the shore.<ref>http://www.pbs.org/wgbh/aso/databank/entries/bpheis.html</ref><ref>http://www.applet-magic.com/quantumdrama.htm</ref>
