**Title: **Unlimited Power: Introduction to pseudofinite structures

**Abstract: **Model Theory seems to be on the dark side of the mathematical spectrum for most mathematicians. In this talk I will introduce the attendees to the power of the dark side by presenting the notion of pseudofiniteness for one famous mathematical object: Abelian groups.

In general, a pseudofinite abelian group is an abelian group that is elementary equivalent to an ultraproduct of finite abelian groups. During my talk, I will give a brief introduction to the definition of pseudofiniteness and the construction of an ultraproduct of abelian groups. Afterwards, I will show that the additive group of the real numbers is pseudofinite.
