and I'm not even a great big nerdy nerd like some people.
This site (that I found linked on BoingBoing.net) has a list of numbers from 1 to 9999 and a reason it's special.
For instance, did you know that;
27 is the largest number that is the sum of the digits of its cube.
2 is the only even prime.
30 is the largest number with the property that all smaller numbers relatively prime to it are prime.
