Johann Bernoulli Quotes and Sayings  Page 1

“But just as much as it is easy to find the differential [derivative] of a given quantity, so it is difficult to find the integral of a given differential. Moreover, sometimes we cannot say with certainty whether the integral of a given quantity can be found or not.”
 Johann Bernoulli 
“The solution "cost me study that robbed me of rest for an entire night."”
 Johann Bernoulli
