Individual events. Events beyond law. Events so numerous and so uncoordinated that, flaunting their freedom from formula, they yet fabricate firm form.

"But some numbers, called dimensionless numbers, have the same numerical value no matter what units of measurement are chosen. Probably the most famous of these is the 'fine-structure constant,' .... Physicists love this number not just because it is dimensionless, but also because it is a combination of three fundamental constants of nature."
