Mathematicians Of The Day
31st August
On this day in 1682, Michael Rolle published an elegant solution to a difficult problem publicly posed by Ozanam:
Find four integers the difference of any two of which is a perfect square as well as the sum of the first three will be a perfect square.
This brought him public recognition.
