After the cataract took Euler's sight, he
In 1771, misfortune struck Euler again, when a cataract in
his left eye robbed him of his sight entirely. Incredibly,
this did not seem to slow him at all. In fact, during his
remaining thirteen years, his publishing output
accelerated. Of the 886 books and articles he produced in
his lifetime - on topics including mathematics,
philosophy, mechanics, electricity, astronomy, optics,
and music - half of them were completed after total
blindness!
