I think you make a great point about adding even further abstraction. I was inspired by Michael Nielsen's idea of "Discovery Fiction"[0], and porting the Sussman library gave me the idea that building the abstraction layers required to to do the physics in "Structure and Interpretation of Classical Mechanics" would make for a great narrative backbone.

I DID start the newsletter thinking I would read Road to Reality and get a community going around the book, and I still want to do that! What happened there was when I tried to talk about the book to anyone that wasn't already dialed on the math I was learning (close family, my wife, software engineer friends) I found that I couldn't communicate what I thought was so beautiful about the book and Penrose's development.

I wanted interactive visualizations that could run in the browser to function as little set pieces, so I could set them down and say

- look, this is what I mean!, and

- Here, you take the controls, let's play!

TRTR will come in, mixed in, I hope, with executable Feynman Lectures etc...

Hopefully that helps fill in some context that I left out!
