Video Explaining PD controllers -- a very nice but surprisingly useful tool in mathematics used to nearly universally balance systems which honestly changed my view on problem solving

I think this is a great little video! Short, sweet, presented in a fun way, and explains the concept in step by step and intuitive way. It actually explains to me PD controllers in a way I hadn’t thought of before.

For things to improve on, I think the title could be more attention grabbing. Emphasizing the Roblox more if you want to get clickbaiting. Honestly, I kind of wanted to see more utilization of Roblox lol. Maybe showcase another example or two where the PD Controllers is utilized.

I’d say you could expand on it some more, but it’s already pretty simple and doesn’t overstay it’s welcome, so I’d say it gets the job done. Maybe slow down the VO just a touch, especially when getting into the more mathy derivatives and whatnot, but overall great job!

The intro to the actual problem was a bit rushed (I would have liked to see the seesaw and dude move in the first few seconds, it would have helped me understand what you were talking about). The explainer was good, not too technical. I had a hard time sharing youre awe, especially at the end, but I liked your enthousiasm nonetheless
