Last year, I gave a talk at Boston Haskell introducing people to the basics of denotational semantics, starting with Scott’s domain theory and touching on the metric space approaches as well. I never did post the slides or notes from that talk.
I have been working on ideas for how to make category theory more accessible and easier to learn, with the belief that it could be eventually be reorganized to the point where it could be taught to high school students interested in math.
I gave a 20-minute talk yesterday at Boston Haskell about the progress of my ideas so far. This stimulated some interesting discussions. I am posting the slides here.
