I’m glad TH-cam thinks I’m smart enough to recommend this to me. I’m not, but it’s cool they think so.
hes basicly talking about a camera and projector that are like star wars holograms
very cool, i've made this simulation that is supposed to be a cymascope simulation, that is a plate of water having point sourced waves in the audio spectrum being the signal input to this video. th-cam.com/users/shortsULSRRkpRJjQ
Thanks for making this great optics content! Really appreciate approaching the subject without straying from applied math; arguably critical to connect physical and mathematical intuitions.
Insane quality. I love this channel. Underrated in my opinion
Thank you very much
this was genius good post!
