      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

      I recently began thinking about how plants get their shape and discovered "morphogenesis" after some inept googling. It seems like a fascinating subject so I'd like to learn a bit more. I have some A-level university courses in chemistry and microbiology, but never dug too deep. So I am looking for suggestions on what to read up on in order to gain some understanding of how plants and other organisms get their shape. The ultimate goal is of course to plant my own house.
