public class PhysicalConstants extends java.lang.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

Little trick to allow for "aliasing", that is, renaming this class. Normally you would writePhysicalConstants.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;
