    This entire youtube channel is a gem btw.

    Delightful video on the lambda calculus and other compution concepts https://www.youtube.com/watch?v=RcVA8Nj6HEo

      Thanks for sharing. I remember reading Introduction to Lambda Calculus many years ago and it was one of those times where I had crazy math dreams and would wonder around SF convinced everything is functions. Like literally everything.

        I miss having the crazy math dreams I used to get when I was in college. If only life could be an endless stream of turning over new stones.

          I wonder if it's an age/brain development thing. I also had crazy math and programming dreams in my early 20s. I don't get those any more, though I still spend a lot of waking time (possibly more now than back then) obsessing over math and programming problems.

    Great, but audio and audio mix is absolutely horrendous and super turbo 2.0 annoying. So much so I had to turn it off and read CC.

    Youtube quality really let's stuff like this down.

    The emergent patterns are... stunning. Especially the ones around 2m35s https://www.youtube.com/watch?v=kL9BTbIGxLg&t=2m35s

    Wow this is stunningly beautiful and extremely cool. And I learned something I had never heard about.

    BRB going to go make hyperbolic outer billards art

    I will never cease to be amazed by the range of thought experiments that get published as math papers.

    This is math junk food. Pretty though.

      It made me reconsider what I think about mathematics in general. So, if it was junk food, it was a nutritious one at that.

      I would call it art, not junk food.
