Class PhysicalConstants

- 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
.

- 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;
