A pitiful play on words. Where's the physics ? A physical
constant forms the absolute algebraic relationship between
covariant quantities. For example, hbar = E / w
A physical quantity that's invariant WRT choice of
reference frame is absolute. 4-vector length is invariant,
and therefore, absolute.
