Student Lectures - All lectures - Set Theory - Classes, sets and proper classes: Oxford Mathematics 3rd Year Student Lecture

This is the fourth of four lectures from Robin Knight's 3rd Year Set Theory course. Robin writes: "Infinity baffled mathematicians, and everyone else, for thousands of years. But around 1870, Georg Cantor worked out how to study infinity in a way that made sense, and created set theory. Modern mathematics can be built on set theory. These lectures begin to explore how".
