Alembert

D’Alembert is best known for his collaboration on the famed Encyclopédie of human knowledge—a 20-year effort with coauthor Denis Diderot.

In memory of that occasion, the child was named Jean Le Rond, and he eventually took the surname d’Alembert.

But d’Alembert was more than an encyclopedist.

It was d’Alembert who realized that it was important to consider the journey as well as the destination.

D’Alembert realized that the Achilles problem vanishes if you consider the limit of the race.
