If you were 35 years old in the year 1225. It would be a very special time mathematically because 35^2 = 1225. That is the square of your age at the moment is equal to the year. Augustus de Morgan, a famous mathematician was one of those lucky people and in 1864 he wrote ''At some point, in my life the square of my age was the same as the year.'' When was Augustus de Morgan born?
