The quartic equation family of Cassinian Ovals are said to undrgird the Geometry of the Cosmos.
They are most easily seen by taking a plate of iron dust filings and having two parallel identical electric currents go down at right angles into the plane of the plate.
The two families of curves so generated model well the undergirding electrical & magnetical inter-relationship permeating the entire cosmos.
The families of curves intersect each other orthogonally.
