Cubic derivation

David Cushing blackboardThis photo is from PhD student David Cushing from Newcastle University. He was deriving the formula for solving a cubic equation, and says it looks messy because it was done ‘live’! The history of the solution to the cubic is a very interesting one, with all sorts of mathematical duels and underhanded dealings by 16th century mathematicians: Tartaglia, Cardano and Ferrari. You can read one account of it here: The solution to the cubic was actually what started the development of complex numbers!

    I will send you a photograph of a blackboard taken from “Constructions of Natural Numbers” courses given by Prof.Dr.Ali Nesin from Bilgi University (Istanbul-Turkey), at world’s *unique* *Mathematics-Willage* placed in Şirince Willage-Selçuk-İzmir-Turkey!

    Thank you for your efforts!
