3 laws of motion:

Mathematics

Fundamental work in the calculus; classical and analytic geometry; finite differences; classification of curves; methods of computation and approximation; probability

Secondary academic interests

Alchemy; Philosophy; Theology

Contribution to Calculus

Binomial Theorem

1) Inspired by Wallis' attempt to square the circle and compute areas of curves:

2) Tabulates the results and gets Pascal triangle and thus:
