- Calculus was on very shaky ground when Newton first used and invented it,
- as Bishop Berkeley pointed out a generation later
- ("The Analyst: a Discourse Addressed to an Infidel Mathematician").
- It was very very unclear what constituted a real proof in calculus at that stage,
- and it wasn't until the late 19th Century that the subject was properly tidied.
- Newton liked proofs he could trust, and that were comprehensible to his peers.

- The fact that he could prove so many answers without calculus
- (after finding them with calculus) doesn't mean that everything
- can be done that way.
- Anybody who thinks they can prove that every complex polynomial
- has at least one root without using analysis
- (the study of the kind of proofs that apply to calculus),
- see me after class.
