A talking head verbalizing what is much clearer if presented in text form. And not new info, AFAIK.Puts me in mind of KhanAcademy - “talking head” is precisely what Khan does not do. At all.
Khan does video of the text or equations being developed/analyzed, rather than a picture of the speaker.
How does it end?
