- Applied category theory, like abstract mathematics, lol?by pishpash
- Yay, John!
- I knew it was going to be Baez just from the title and domain.by esafak
- I participated there and couldn't guess for the life of me how does Baez gathers the amount of energy needed to put together all the materials, setup all the exercises and review and comment all the participation in a tuition free everybody-welcomed online experience such as that, beyond his normal academic duties. In the link there are the e-lectures but all the online forum give-and-take is sadly lost.by jesuslop
- The part in the beginning about Galois Connections is very worth learning. It has countless applications.by ufo
- As a programmer interested in category theory, I found this book a rather good balance between the abstract non-sense of CT and what I might actually use in programming. I wonder if anyone else has good books to recommend? I feel that the contents of the book remains a bit hard to appreciate in full unless you have ran into these concepts previously.by Jhsto
- Not sure of your level, but as a beginner, these two were recommended to me on HN previously:
- https://www.cambridge.org/highereducation/books/conceptual-m...
- https://bartoszmilewski.com/2014/11/04/category-the-essence-... (a blog series on CT specifically for programmers)
by jhartikainen - F. William Lawvere - Conceptual Mathematics: A First Introduction to Categories
Eugenia Cheng - The Joy of Abstraction: An Exploration of Math, Category Theory, and Life
She builds up to the category theory chapters.
