The Number 3 in Physics

The Number 3 in Physics

It seems that Physics likes the number 3 at all levels, from the macroscopic down to the quantum level. Consider this..

- There are 3 macroscopic spacial dimensions.

- The Standard Model of elementary particles has 3 families of fermions.

- The Color Force has 3 charges, RGB.

- And we now have the recently discovered "Efimov States" which are bound groups of 3 bosons.

Coincidence? Maybe. Maybe not.
