I know that there are developers and engineers out there who would like to learn more physics, but either need the structure of courses, or don't have much time.
Would you pay for this? I'm thinking a Netflix-ish subscription fee. iOS, Android, PC, Mac, Linux.
You have deigned to ask this very question on the forum. Presumably because finding a good answer by searching for existing content was not likely to address your question.
Now don't you think graduate-level physics is a little bit more hard and complicated to learn?
