- Elementary particles are pointlike and points are small more or less by
- definition.

- The above snide but true answer doesn't count bound states like protons
- as being elementary. One could ponder the properties of bound states
- that were as big as a baseball... for example, a baseball is itself a
- bound state! Of course, a baseball consists of lots more elementary
- particles than a proton does. A bound state consisting of only a few
- elementary particles but big as a baseball would probably be very weakly
- bound hence too fragile to have much fun with.
