Can you give examples of laws in science that have no mathematical formula attendant to them

This is not homework, haven't needed that for a while now.

I'm just interested in any laws that science has brought forward that
do not have any related mathematical formula.

..

Pretty much every law in biology. This is probably due to the fact that most aspects of life are too complex to be described in a simple mathematical formula.

Cell theory:
The cell is the fundamental building block of all (terrestrial) life.

Mendel's laws:
Each individual possesses two alleles for any given trait; each parent randomly gives one to the offspring.
Traits are inherited independent of each other (later corrected to only apply to unlinked genes, Mendel had no way of knowing about chromosomes)

The law of evolution:
The allele frequency within a population changes over time
