- See "Huygens, Barrow, Hooke and Newton" by V.I. Arnol'd.
- He gives the above limit as an example of a problem
- that mathematicians today simply can't solve quickly (in
- contrast to their predecessors). He remarks that the only
- exception known to him, G. Faltings, proves the rule.

- The book is well worth reading, by the way.
