Raj's work on scientific machine learning in epidemic modeling is a treat for those who haven't seen it (https://youtu.be/YiDODWjpACo) (bias: I am a co-author on these studies, but he has really cool animations!)
Those animations look like they are lifted from 3blue1brown without attribution...
What do you mean? Are you praising them by making the comparison, or saying they are plagiarized?
I really think you should clarify.
I dont either see the video but 3b1b create Manim a program to make that type of animations
Which video? The guy has open sourced the library he uses to construct the animations
