Detailed Description

This class holds several useful physical constants

Values for physical constants correspond to 2018 CODATA internationally recommended values of the Fundamental Physical Constants.

See:

• National Institute of Standards and Technology (NIST): http://physics.nist.gov/constants
• Table of physical constants: https://physics.nist.gov/cuu/Constants/Table/allascii.txt

This class holds several useful physical constants, which are accessed through static const pointers. For example:

SBQuantity::mass m = *SBConstant::protonMass;

Short name: SBConstant
