Why was Eugene Wigner so impressed and puzzled with why mathematics describes nature so successfully? Our laws of nature that are expressed in mathematical forms are over idealizations of physical reality. For instance, there is no real continuum but such a concept is useful when describing macroscopic systems. Abstract human thoughts are associated with external things but are distinct from them. That is why one of the essential components of science is predictive power and not merely explanatory power. Predictions attest to the usefulness of human thought when describing nature. Predictive power sets science apart from pseudoscience.

The last sentence presents a curious dogma. It is purely nominalistic, a
view not universally shared. Many mathematicians are persuaded that they
discover rather than construct such relationships. Of course, one may
recognize that all terms are human inventions, but this does not mean
that anything we talk about has no reality beyond our concepts.

If pi is "a purely human conception," it follows that the rest of math is
equally so. Consequently, the equations that describe physical reality do
not. It's all rather arbitrary, and there is no lunatic fringe of
