To understand how error correction works and to learn more about Hamming codes & Reed-Solomon, 3Blue1Brown and Ben Eater were invaluable. 3Blue1Brown and Ben Eater are by far some of the best educational content creators within their fields, mathematics and computer engineering respectively.

I would strongly recommend anyone interested in the topic to check out any of these videos:

How to send a self-correcting message (Hamming codes): https://www.youtube.com/watch?v=X8jsijhllIA

Hamming codes part 2, the elegance of it all: https://www.youtube.com/watch?v=b3NxrZOu_CE

And any of Ben Eater's five videos on error correction: https://eater.net/crc

As an aside, Ben Eater does all of his videos and demonstrations using an 8-bit computer he has built step by step in videos on a breadboard. Very impressive and inspiring.
