there are only 6 major constants according to Martin Rees:

**?, Nu**: the ratio of the coupling constants for the electroweak force and gravitation (circa 1043). The former is simply the fine structure constant, while the latter is the gravitational coupling constant;**?, Epsilon**: related to the strong force;**?, Omega**: the number of electrons and protons in the observable universe (circa 1080);**?, Lambda**: the cosmological constant;**Q**: a ratio of fundamental energies;**?, Delta**: the number of spatial dimensions.
