Constants

Fundamental Physical Constants

"This document gives the values of the basic constants and conversion factors of physics and chemistry resulting from the 1986 least-squares adjustment of the fundamental physical constants as published by the CODATA Task Group on Fundamental Constants and as recommended for international use by CODATA". By E. Richard Cohen and Barry N. Taylor.

Mathematical Constants

"All numbers are not created equal; that certain constants appear at all and then echo throughout mathematics, in seemingly independent ways, is a source of fascination. Just as physical constants provide "boundary conditions" for the physical universe, mathematical constants somehow characterize the structure of mathematics." Steven Finch, Research and Development Team, MathSoft, Inc.
