Science + Technology

• Applied Science - In depth videos about random science-y things this dude finds interesting. No clickbait, just an excited dude talking about a project he tried.

• Atomic Frontier - A lot like Tom Scott. He's also a rare case where the video is more interesting than the title/thumbnail. Generally focused on science-y topics + has shockingly high production value considering the dude seems to be an overworked college student.

• NileRed/NileBlue - Crazy in depth chemistry videos. Personally find NileBlue more entertaining as he tends to explore things he's not that great at.

• Practical Engineering - Explanations of various civil engineering concepts.

Other

• Krazam - Legendary comedy channel focused on software engineering related topics. Most famous video - microservices.

• You Suck At Cooking - Short videos presenting recipes in an entertaining way.

• Studio Binder ; High quality videos about all things movie/video production. Owned by a movie production software company so you're gonna see ads for it in every video but SponsorBlock gets rid of that with no issues. Ultimate Guide to Camera Movement - Every Technique Explained
