Question

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!

After the cataract took Euler's sight, he wrote more books and articles

.

About how many books and articles did Euler complete after he lost his sight entirely? 450

Answer 2

#1) wrote more books and articles than before; #2) 443

Explanation:

The summary states that Euler's publishing output accelerated after the cataract. This means that he wrote more books and articles than before.

Since half of his books and articles were produced after the cataracts, this means he produced

886/2 = 443 after the cataract.
