Extractions: [Physics FAQ] original by Steve Carlip The fundamental laws of physics, as we presently understand them, depend on about 25 parameters, such as Planck's constant h, the gravitational constant G, and the mass and charge of the electron. It is natural to ask whether these parameters are really constants, or whether they vary in space or time. Interest in this question was spurred by Dirac's large number hypothesis. The "large number" in question is the ratio of the electric and the gravitational force between two electrons, which is about 10^40; there is no obvious explanation of why such a huge number should appear in physics. Dirac pointed out that this number is nearly the same as the age of the Universe in atomic units, and suggested in 1937 that this coincidence could be understood if fundamental constants in particular, G varied as the Universe aged. The ratio of electromagnetic and gravitational interactions would then be large simply because the Universe is old. Such a variation lies outside ordinary general relativity, but can be incorporated by a fairly simple modification of the theory. Other models, including the Brans-Dicke theory of gravity and some versions of superstring theory, also predict physical "constants" that vary. Over the past few decades, there have been extensive searches for evidence of variation of fundamental "constants." Among the methods used have been astrophysical observations of the spectra of distant stars, searches for variations of planetary radii and moments of inertia, investigations of orbital evolution, searches for anomalous luminosities of faint stars, studies of abundance ratios of radioactive nuclides, and (for current variations) direct laboratory measurements.

http://cern.ch/jowett/Accelerator/ConstantsUnits.html

Extractions: This package provides symbols for physical constants commonly occurring in accelerator physics. The properties of these symbols include their values and units in a very natural way. In addition the package provides capabilities for painless conversions between many systems of units and for checking that the dimensions of expressions are consistent. Basic use of the package is via a palette of buttons that will appear on your screen when you load it. Version 3.0 of the package (released 19 January 2001) greatly improved and simplified the facilities for checking dimensions of expressions. The package now maintains an internal database giving the dimensions of all symbols registered with the IntroduceSymbol command. Compound symbols can be introduced with
