Ask HN: Which are some of the best online lecture series you have studied?

You really should narrow it down.

Bill Shillito - Introduction to Higher Mathematics | Just the clarity of presentation and pacing.

MIT Calculus Revisited - An almost perfect no nonsense presentation (I like black boards too)

Francis Su - Real Analysis - Very engaging lecture style and great board work.

Feynman Messenger Lectures - Well its Feynman, and the content is interesting if you are still somewhat new to it.

BBC OU courses from generations ago (e.g. Geometrical Topology)

NPTEL can have some amazingly well done lecture courses.

Also StatQuest and Luis Serano for intuition/conceptualization in Stats & ML.

I have been aggregating YouTube lectures at various curation channels that contain what YouTube calls Multiple Playlists that is lists of playlists. I'm perhaps not even half way into filling them up and the lecturers are choosingbto record and upload their courses more and more.

Note that YouTube has a strange UI design that people overlook. You have to click on a multiple playlist title to see all its playlists.

They’re from another decade now but the Yale Online Courses are really good

Not an online lecture series per se, but rather some interesting readings: https://www.ratherlabs.com/blog
