A Soulwinning Mathematician
Helped progress the study on partial differential equations
Helped progress the study of polygons
In 1811 he proved that the angles of a convex polyhedron are determined by its faces
He was the first to make a rigorous definition of the conditions for the convergence of infinite series.
In 1829 he defined for the first time a complex function with a complex variable
Cauchy would often visit sick friends and led them to faith in Christ.
Yet he did not always have good relations with all scientists because of his Catholic views. His Catholicism associated him with the Jesuits who quarreled with the Académie des Sciences.
This was said about him by a French journalist, “…It is a curious thing to see an academician who seemed to fulfill the respectable functions of a missionary preaching to heathens.”
Although he was a Catholic, many of his views on Christianity parallel those of the Puritans and Protestants. For instance
He gave a report on the theory of light and attacked an author that said that Newton had not believed that people had souls.
During the Second French Revolution Cauchy was exiled from France. Before the civil war he had taken an oath to Charles X. Because he was an honest man he would not break that oath to take another. He continued his work in Italy for a while and learned to speak their language well. Then he moved to Prague with Charles where he taught the prince and was given the title of Baron by the king.
He furthered the mathematics in nearly every field, especially calculus .
