That fact is betrayed by the the similarity of the shapes of atomic orbitals and the sensitivity patterns of Abisonic B-format channels.

...and the same patterns appear on the unit disk with the Zernike polynomials, used to describe optical aberrations and more.
I noticed that (similarity between the graphs and the shapes of atomic orbitals), and assumed that was what the article was about. And it wasn’t, and never brought it up, so I was thinking maybe I was confused about the similarity. So thank you for showing me I was not.
