Use a better marker, what you wrote on the whiteboard is almost unreadable for me.
Expanding on the previous point, write bigger and make better use of the space on the board.
If you have complex graphics, pre-make them accurately and print them out, put them on the whiteboard with weak tape. (What is the weird of bridge at the start?)
Use Whisper to make subtitles to help non-native speakers (as another commenter suggested).
Invest in a tripod to have the camera at a natural height instead of bottom to top.
I did not watch the lectures, this feedback is from skimming around in the first one.
In lecture 3, visualizing the Fourier matrix (Discrete Cosine Transform) matrix, could be really interesting.
Are the lectures ordered by something or following a thread? If so you should make it clear by posting an overview lecture at the start.
Do not wear glasses, it makes you look weird and lose connection to the viewer.
Thanks a lot for your effort, we really need to spread mathematical education for the benefit of the whole society.
I don’t think these are necessarily bad suggestions if there were a future series. But my sense is that John did this for the people in the audience, somebody asked him to record it so he did, and now he’s putting them online in case they’re useful to anyone. It’s very hard to make good production quality lectures, and it would have required more effort. But it sounds like John knew this and decided he would rather spend his time elsewhere, which is completely his choice to make. As written, these suggestions feel a bit pushy to me.
Yes, the tone of my comment could be improved. I appreciate him for publishing his lessons to the community and wanted to give some suggestions to improve (eventual) future ones, if he feels like the higher quality is worth the higher effort, and with no obligation. “Al caval donato non si guarda in bocca” (You should not look at the teeth of a gift horse (to learn about its age))
