come venture into number theory in this spooky post halloween talk, where i plan on talking about some objects that are (at least tangentially) related to number theory. which objects will show up? maybe elliptic curves, maybe p-adic numbers, maybe lie groups. it's a bit of a mystery, so come to the talk to find out! in order to keep the talk from being too scary, i'll try to keep the prerequisite knowledge to a minimum.
