And then my other drawing question is if you could draw how an algorithm works? How an algorithm works? Just on the other half of the page. And I'll leave this on if you want to narrate what you're drawing. Sure. So my understanding is that you have some sort of input from the user and that input will sort of do whatever the user wants. So you have some sort of intermediate step, call that the middle, and then the algorithm will have some sort of output. Which is whatever the user wants the algorithm to do or compute on the medium in the middle. Okay and where have you heard the term algorithm before? In computing mostly. Is that something you work in? No, I do things with physics. Oh, okay. But have taken a classes? Yeah. Okay, got it.
