Science channels on YT
 

Lately I've enjoyed watching pop-science videos on YT.

My favourites so far are:

Any recommendations for similar channels?
I prefer shorter videos (<20 min). I also hate it when presenters put on some kind of silly persona or are otherwise annoying (I've grown to like Michael Stevens, but only after initial discomfort). It'd be also nice if the things shown and explained aren't too mundane and threadbare.

Professor Jim Al-Khalili has made some good documentaries for the BBC covering things like chemistry, mathematics, but mostly physics, especially quantum mechanics, many of which are up on youtube.

Here's a taster:

Thanks!
It's a little longer than I'm used to, but the topic really interests me.
Sadly the BBC's own streaming site (you've been posting several interesting links over the last few weeks) is seemingly only available in the UK.

Yeah, BBC iPlayer is only available in the UK. :(

Some of the older Horizon shows can be watched on youtube. These too are an hour in length I'm afraid but are (almost) always good. The following episode gives you a good idea what the show is like, if it's your kinda thing then search for 'BBC Horizon' to find more episodes.

Tried both videos, but didn't make it far.
As it would be logical for TV shows, they deal with the stuff on a very basic level and didn't offer me anything new or exciting.
Also the attempts at a narrative in the Horizon video felt pretty lame.
But thanks anyway. I'll still check out some of the other vids in those series, might stumble across something good.

No worries. It is hard sometimes finding that fitting amount of info in programmes. I'd suggest maybe watching a few university lectures, but they can have a bit too much info and/or are often boring.
