**I don’t find numbers particularly interesting**, in and of themselves. Mathematics’ folklore suggests that, even if you’re misled into thinking that, for example, 1729 is an uninteresting number, you may be wrong. Whatever. I’m just not a numbers person.

But you can *combine* numbers to get interesting things. When you put enough numbers together you get *Toy Story*. Beyond interesting: it was moving. All of the polygons and sound waves (1-D functions of time) are mathematical, and the movie was ultimately encoded as bits — so *Toy Story* is one long number.

**Drama** can be built up with much less. Consider the set `{Jun, Kiko}`

. There is a function which maps pairs from the set to `{0,1}`

: a two-place relation

- ƒ(Jun, Kiko) = 1
- ƒ(Kiko, Jun) = 0

`{0,1}`

is isomorphic to `{true, false}`

and the two-place relation’s name is “Love”. True, **Jun loves Kiko**. False, **Kiko does not love Jun**.

See what I did there? ƒ(a,b)=1 && ƒ(b,a)=0 ——functor—→

- Love(Jun, Kiko) = T
- Love(Kiko, Jun) = F

The possibilities take the shape of the vierergruppe:

A love triangle isn’t far off. And now you have my attention if you want to talk about cohomology or something. Oh, the cohomology of a love triangle? The cohomology of unrequited love? Yeah. I could get interested in that.

**This is why I read mathematics.** Not because numbers fascinate me. Not because deduction is fun. Because with math you can think about sh_t in a totally new way.
