      "Discovery fiction" is a fictional re-creation of an invention of something. It's an awesome way to teach how something works, because you have to explain what problems led to each part of the solution. (1/6)

      I was first introduced to this style by @mojombo and his "The Git Parable", which walks you through designing a git-like source control system. https://tom.preston-werner.com/2009/05/19/the-git-parable.html … (2/6)

      Yesterday @michael_nielsen tweeted a mini fiction about the positional number system. https://twitter.com/michael_nielsen/status/1174420006907473920 … (4/6)

      Imagine you're a designer or mathematician living in ancient Rome. Being a curious & imaginative sort, used to exploring wild ideas, you ask yourself: is there some way you can improve on the roman numeral system? Might it be possible to find a better way of representing number?

      The best part of discovery fiction is seeing the sequence of problems, their solutions, and the problems those solutions create, leading to more solutions, a la @DavidDeutschOxf and "The Beginning of Infinity". (5/6)

      I want a whole book of these! This should be a thing! What other topics could there be? It works best for human-invented (not discovered) complex topics. I'm thinking TCP/IP, Diffie-Hellman, Paxos, JPEG. (6/6)

      I don't see why you believe this. I have hundreds of thousands of words of notes in this style for the natural sciences. It works just fine.

      I'd love to see an example! I don't immediately see how to demonstrate conscious problem-solving for something that wasn't consciously problem-solved, but even better if that's possible.

      I'm not sure I've written one up very consciously in that style. But it was very nearly the default way I approached all mathematics and physics for more than a decade. Funny to think that I "translated" a lot of that into the more conventional style.

          In particular, for a long time my rule was to _always_ attempt to derive results myself first, while looking as little at others work as possible. Very often this failed, of course, but I sometimes succeeded. Such is very naturally discovery fiction.

          Now that I think about it, discovery fiction is how I explained loops in my "Introduction to Programming": https://www.teamten.com/lawrence/programming/intro/intro8.html …
