Most mathematics video present the results of deep researches. Results only. How does one come up with a result like that? Silence. Not even a hint of the first step along the path.
This video caught my eye because it walks through the thought process of coming up with a proof. The result is not deep, and the proof is not hard, but topic "how to get started on coming up with ones own proofs" is rarely tackled.
There doesn't seem to be anything here yet
