Set Theory

Set theory is a really useful branch of mathematics that studies collections of things, which are called sets. For example, a bag of marbles could be a set.

Mathematics

Set theory is foundational in mathematics, providing basic mathematical concepts that can be used to explain other concepts such as numbers.

Databases

Set theory concepts underpin how databases work and how we reason about them. They provide a common language to talk about database operations.

Logic

Logic combined with set theory can be used for complex reasoning about the world around us.
