Person: Stampioen, Jan Jansz de Jonge
Jan Stampioen was a Dutch mathematician who published a work on spherical trigonometry.
Mathematical Profile (Excerpt):
 We know relatively little about the life of Jan Stampioen Jr, and essentially nothing about his early life, but he appears to have been brought up and educated in Rotterdam.
 Stampioen taught mathematics in Rotterdam where, in 1632, he published his own treatment of spherical trigonometry appended to van Schooten's sine tables.
 Descartes presented a solution but it was rejected by Stampioen as not being complete.
 Stampioen's criticism was fair for although Descartes had taken the geometric problem and derived the correct quartic equation, he left the problem there without solving the quartic.
 Fair though Stampioen's criticism was, it was definitely unwise for he made an enemy of Descartes who was a very powerful figure.
 In 1638 Stampioen moved from Rotterdam to The Hague on being appointed tutor to the twelve year old Prince William.
 How successful Stampioen was in tutoring William, and whether this had any bearing on his years as Prince of Orange, we can only leave to the imagination.
 The move to the Hague to become tutor to William, however, set Stampioen on a new career for, while in The Hague, he opened a printing shop in which he printed his own writings on mathematics.
 In 1639 Stampioen published Algebra or the New Method , a work which he had written while still teaching in Rotterdam.
 The problem which Stampioen was interested in came as a consequence of using the CardanTartaglia formula to solve cubic equations.
 Stampioen let this cube root be A+√BA + √BA+√B, where a,b,Aa, b, Aa,b,A and BBB are all natural numbers.
 Since we know that Descartes described his rule in a letter to Waessenaer written on 1 February 1640, it looks as though Descartes was probably out to discredit Stampioen and realised that it would be even more telling if it came from a relatively unknown mathematician.
 Stampioen rejected Waessenaer's solution which prompted Waessenaer to reply with a broadly based attack on the mathematics contained in Stampioen's Algebra or the New Method.
 Was Stampioen correct?
 It may indicate that Descartes actually had a higher opinion of Stampioen than that which he showed in public.
 Little else is known about Stampioen.
Born 1610, Rotterdam, Netherlands. Died 1690, The Hague, Netherlands.
