An enjoyable 25-minute introductory talk: YOW! Lambda Jam 2019 – Ken Scambler – Applied Category Theory (slides)
What do programming, quantum physics, chemistry, neuroscience, systems biology, natural language parsing, causality, network theory, game theory, dynamical systems and database theory have in common?
As functional programmers, we know how useful category theory can be for our work – or perhaps how abstruse and distant it can seem. What is less well known is that applying category theory to the real world is an exciting field of study that has really taken off in just the last few years. It turns out that we share something big with other fields and industries – we want to make big things out of little things without everything going to hell! The key is compositionality, the central idea of category theory.
