What is a perfect physical science constant?
When I examine the NIST list of fundamental physical constants, they identify a group of constants that
they categorize as "universal".
Universal constants
Each of the constants have numeric values that are dependent upon SI base units or SI derived units. There
is not one unit in the list that is an actual invariable universal unit.
Units
Mathematics has defined a number of perfect constants, they are dimensionless and are truly universal.
In the physical sciences it is rare to find a dimensionless constant, at least there are none defined in the
SI list of constants. The next best thing to a perfect physical science constant is one that would be defined
by only one unit, but that unit should be something that is an actual universal value.
Are there any such physical science constants?
