Exploding Dots

2.1 Welcome

Lesson materials located below the video overview.

All right. It’s time to explain what the machines from the previous chapter are really doing. (Did you already figure it all out? Did you play with the final explorations of that chapter?)

Let’s go back to the \(1 \leftarrow\ 2\) machine first and make sense of that curious device. Then understanding for all the other machines will follow.
