mpylab.tools.physical_constants module

Physical constants used by mpylab tools.

The canonical uppercase names and their scientific aliases are protected, unit-aware scuq.constants.PhysicalConstant objects based on the CODATA 2022 values. The historical names c, mu0, and eps0 remain plain SI-valued floats for compatibility with existing scripts. Those floats contain expectation values only and therefore discard the uncertainties of mu_0 and epsilon_0.

pi remains math.pi because it is a mathematical constant rather than a measured physical constant.
