For educative scientific YT channels I’d recommend Veritasium, The Action Lab and NileRed to name a few. They produce top quality scientific videos about really interesting phenomenas and experiments. And the best part is they make the concepts simple to understand without the need of a degree or smth lol

What’s bad about it? OP has voluntarily turned ads on on ddg (to support ddg I guess). DDG has been working great for me, so care to enlighten me please?

I don’t personally listen to podcasts often, but a Spotify client called Spotube can play the same Spotify podcasts ad-free.

On Android you can get Spotube from its official Git site, or just from the F-Droid app store. iOS/macOS guides are also in the website.
