About the Number 1,818 (one thousand eight hundred eighteen)

While adding a Karl Marx quote to his quote collection, GDT was reminded that Karl Marx died on Pi Day of 1883. There was already a nBAB for 1883, so this nBAB for the number 1818 was created because Marx was born on 5 May 1818.

The Karl Marx quote... "A man cannot become a child again, or he becomes childish." Note: MathBabbler frequently feels childish while playing with numbers.
