This lecture is part of an online algebraic geometry course (Berkeley math 256A fall 2020), based on chapter I of "Algebraic geometry" by Hartshorne. The full set of lectures is in the playlist "Algebraic geometry I: varieties". 

(The course continues in the playlist "Algebraic geometry II: schemes" based on chapter II.)

The first lecture describes a birational map from a circle to a line.
