THE GENERAL SOLUTION OF A CUBIC: CARDAN’S METHOD
a brief history of cardan or gerolamo cardano
Jerome Cardan, or Gerolamo Cardano (1501–1576), was a Renaissance mathematician, physician, astrologer, and gambler who was the first to describe the Cardan suspension and the Cardan joint in detail.
A subcategory of Euler angles is often called Cardan angles
He wrote the book “ The Book on Games of Chance” on his gambling experience in the field of probability
