Title: Adjunctions! Everywhere!

Abstract: What do free groups, existential quantifiers and Stone-Cech compactifications all have in common? This isn't the start of a bad maths joke: in fact these things are all examples of left-adjoint functors. The category theoretic notion of an adjunction captures a number of interesting concepts in disparate areas of mathematics. Abstract nonsense is inevitable but I will exercise restraint in using it.
