Papers We Love Belfast's new and experimental book club has selected Milewski's Category Theory for Programmers ( as our first book. The aim is to hold a monthly book club for programmers to get together and discuss a "must-read" CS text.

Trello board ( to vote for upcoming books.

On November 11th we'll be discussing part two and a few chapters of part three of the book, up to and including Chapter 3, "Free and Forgetful Adjunctions". It is not required to read the book before attending the group, but probably recommended to get the most out of the discussion.

For some time now I’ve been floating the idea of writing a book about category theory that would be targeted at programmers. Mind you, not computer scientists but programmers — engineers rather than scientists. I know this sounds crazy and I am properly scared. I can’t deny that there is a huge gap between science and engineering because I have worked on both sides of the divide. But I’ve always felt a very strong compulsion to explain things. I have tremendous admiration for Richard Feynman who was the master of simple explanations. I know I’m no Feynman, but I will try my best. I’m starting by publishing this preface — which is supposed to motivate the reader to learn category theory — in hopes of starting a discussion and soliciting feedback.

Please consider joining us for lunch/coffee and some interesting conversation. Hope to see you there!
