As given by Britain's brilliant, opinionated Sir Arthur Stanley Eddington, the seven fundamental constants of Nature are:
e, the charge of an electron;
m, the mass of an electron (at rest);
M, the mass of a proton (at rest);
h, Planck's constant (of atomic action) ;
c, the velocity of light;
G, the constant of gravitation;
λ ,the cosmical constant (of large-scale repulsion).
The first four constants are fundamental to Quantum Mechanics, which deals with the microcosm of the atom. The last two are fundamental to four-dimensional spacetime, which deals with the macrocosm of the universe....
