Biot_Jean Quotes (2 quotes)
Biot, who assisted Laplace in revising it [The Mιcanique Cιleste] for the press, says that Laplace himself was frequently unable to recover the details in the chain of reasoning, and if satisfied that the conclusions were correct, he was content to insert the constantly recurring formula, Il est ΰisι a voir [it is easy to see].
How did Biot arrive at the partial differential equation? [the heat conduction equation] Perhaps Laplace gave Biot the equation and left him to sink or swim for a few years in trying to derive it. That would have been merely an instance of the way great mathematicians since the very beginnings of mathematical research have effortlessly maintained their superiority over ordinary mortals.
