The miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve.

---E.P. Wigner from ``The Unreasonable Effectiveness of Mathematics in the Natural Sciences'' in Symmetries and Reflections, (Oxbow Press, Woodbridge, Conn., 1979), p. 237.
