I’ve been getting bogged down in discrete lately, trying to keep up with all the concepts. The tricky thing is this: while most of the concepts are easy to understand, the nuances can trip you up when you’re dealing with a lot of ideas at once.
I was hanging out at a coffee shop downtown with Chason last week when I decided to start a glossary. I was having a hell of a time understanding what an “inverse image” was. The more I tried to get it, the more I realized I was having trouble because I didn’t understand a bunch of root concepts fully. So, I did something I’ve done in the past – I started a glossary.
This isn’t just a glossary of terms. It’s a particular phrasing of ideas designed to goose me into remembering something if I’ve forgotten it. In the spirit of Griffith’s physics books, I try to include a rigorous definition, and a friendly informal one. I wish all texts did this.
Check it out! I’ll be updating as I learn, and perhaps it’ll be useful to some of you struggling in this area.
