How to Count Infinity

The video explores the concept of counting, starting with basic set equivalence and moving to infinite sets. It discusses how infinite sets can be compared, using the example of real numbers and integers. Cantor's diagonal argument is introduced to show that there are more real numbers between zero and one than integers. The video concludes with the idea that some infinities are larger than others.
