Wolfram Research's MathWorld is a comprehensive and interactive mathematics encyclopedia intended for students, educators, math enthusiasts, and researchers. It has been assembled by internet encyclopedist Eric W.ÊWeisstein with assistance from the mathematics and internet communities. Like the discipline of mathematics, this site is continuously updated to include new material and incorporate new discoveries. This is a free service for the mathematical community provided by Wolfram Research, makers of Mathematica, with additional support from the National Science Foundation.

Lissajous Curve -- from MathWorld - Weisstein, Eric W.
Lissajous curves are the family of curves described by the parametric equations x(t) = A\cos(\omega_x t-\delta_x) y(t) = B\cos(\omega_y t-\delta_y), sometimes also written in the form x(t) = a\sin(\omega t+\delta) y(t) = b\sin t. They are sometimes known as Bowditch curves after Nathaniel Bowditch, who studied them in 1815. They were studied in more detail (independently) by Jules-Antoine Lissajous in 1857 (MacTutor Archive). Lissajous curves have applications in physics, astronomy, and other...

Quadrivium -- from MathWorld - Weisstein, Eric W.
A word derived from the Latin roots quad- (four) and via (ways, roads), therefore a crossing of four roads. In medieval universities, the quadrivium consisted of the four subjects in the upper division of the seven liberal arts: arithmetic, astronomy, geometry, and music. See also: Trivium
