Abstract
In this talk I will define ordinals and cardinals. I will prove some very basic properties of ordinals, including transfinite induction, before moving on to cardinals and discussing alephs and cardinal arithmetic. At the end we will see some of examples of how these things are used in different areas of mathematics.
