For me it’s DJ Peach Cobbler. I’ve been watching his videos since he had around 2,000 subscribers. Now it’s nearly 450,000.
He used to mostly make videos on games, now he does a lot of history stuff too. He also has a little satirical news show, and a few tasteful shitposts. A really diverse YouTube channel.
What’s your favorite YouTube channel that’s not a mainstream big-name like pewdiepie, mrbeast, ksi, etc…?

A fairly clear explanation with a small amount of simple mathematics, probably the minimum that is possible. It helps to understand at least a little such a complex and illogical science for the average layman.
