You may find it delightful to encounter sequences composed of prime numbers, or numbers who are divisors of each other. Maybe they're components of your first phone number, your first car license,...
You may find it delightful to encounter sequences composed of prime numbers, or numbers who are divisors of each other. Maybe they're components of your first phone number, your first car license, your kid's birthday, the day a relative died, or the release of Star Trek II: The Wrath of Khan. What numbers and combinations of numbers you see everywhere that you find curious, amusing, or meaningful?

So, my 5-year-old nephew is obsessed with huge numbers, especially named numbers such as googol, duodecillion, and centillion. The other day I spent some time reciting these numbers to him, and trying (and failing) to describe them. What I need are some cool facts about these numbers, such as "there are 1 quadrillion cat hairs in the world", or "there are not enough stars in the universe to fill one googol".
Besides math, his main interests are super-heroes and, apparently, cars.
I'm not a math or physics guy, so hopefully you guys can help me cheat :P
