public class PhysicalConstants
extends Object

High Energy Physics coherent Physical Constants. This class is a Java port of the C++ version found in CLHEP 1.4.0, which in turn has been provided by Geant4 (a simulation toolkit for HEP).

For aliasing see physicalConstants.

public static final PhysicalConstants physicalConstants
Little trick to allow for "aliasing", that is, renaming this class. Normally you would write
 PhysicalConstants.twopi;
 PhysicalConstants.c_light;
 PhysicalConstants.h_Planck;
 
Since this class has only static methods, but no instance methods you can also shorten the name "PhysicalConstants" to a name that better suits you, for example "P".
 PhysicalConstants P = PhysicalConstants.physicalConstants; // kind of "alias"
 P.twopi;
 P.c_light;
 P.h_Planck;
