The other day, Jim excitedly told me, "Did you realise I will turn x years old in the year x^2?"
He wasn't the first to think of this. The 19th century mathematician August de Morgan used to used to boast that he was x years old in the year x^2. He died in 1871.
In what year was Jim born? When will his prediction be true? In what year was de Morgan born? What is x in each case?

No answer is particularly WRONG, but I wouldn't think of someone living to 111... I would think they would die earlier.
The way I got 111 was 2003-1892.
What TomM says is true too... I assumed this puzzle was recent... This may not be right.
