Maxwell’s theory of electromagnetism was derived from 4 field equations, later converted to vector equations by self-taught Oliver Heaviside, because he hated field equations.
The other 196 of JCM’s equations were discarded by Heaviside because they were “impossible”.
Original copies of JCM’s work are either very rare or lost.
