Abstract:
Given a large number of particles where each pair
experiences a force determined by their distance.
When can a flock form, and what should it look like?

Suppose that any two particles attract when they are
far apart, and repel each other when they are close. One
may conjecture that a sufficiently large number of
particles would organize itself in a round flock; if the
number of particles is too small, they would disperse. I will
describe recent progress towards this conjecture,
and mention open problems.
