Bartolomeo SoveroBartolomeo Sovero was a Swiss mathematician.BiographySovero was born in Corbières in 1576. In 1594 he entered the Jesuit order and studied logic, mathematics and theology at the Jesuit College of Brera. In 1604 he left the Society of Jesus. in 1624 Sovero replaced Giovanni Camillo Glorioso on the chair of mathematics at the University of Padua. In his main work, Curvi ac recti proportio, Sovero proves to be a precursor of the geometry of indivisibles and of the method called "proportional parallel movement". It is elucidated by an algebraic formulation. The work of Sovero gave rise to two important polemics, one with the first successor of Galileo in Padua, Glorioso; the second between Guldin and Cavalieri on the subject of the latter's originality.Works*
