Description

SciShow Tangents is the lightly competitive knowledge showcase from the geniuses behind the YouTube series SciShow. Every other Tuesday, join Hank Green, Ceri Riley, and Sam Schultz as they try to one-up and amaze each other with weird and funny scientific research... while not getting distracted. There will be tangents about video games, music, weird smells, surprisingly deep insights about life, and of course, poop, but it always comes back to the science.

It's all right there on the tin - this episode is BANANAS. And not just because we have the most guests we've ever had in Tangents history. Not even just because one of them is a super special surprise RETURN friend of the pod. And not even because we check out some flowers that are way more uncomfortable to look at than you think.

No, your eyes and ears don't deceive you - this is, in fact, a super special cross-feed treat from our friends over at Crash Course in the form of the first episode of their brand new show, "Crash Course Pods: The Universe." Hosted by novelist John Green and astrophysicist Dr. Katie Mack, "The Universe" is a podcast about the history of the entire universe, from its explosive beginnings to its mysterious, but inevitable, end. In this first episode Dr. Mack walks John through the Big Bang and the very first micro-moments of the universe, and some of the ways that that ancient event is actually still connected to us, here, today. It's great, we really like it, we're really proud of the Crash Course team, and we thought you guys would also really enjoy the show! So to make it easy, we put the entire first episode right here! The rest of John and Dr. Mack's conversation will cover 11 episodes airing every other week on the Crash Course YouTube channel at youtube.com/crashcourse or wherever you get your podcasts. Give it a listen, and we hope you enjoy!

in our solar calendar (iran), weeks start from zero (shambe which is saturday) then yekshambe (yek means one in farsi) (which is sunday) and doshambe (do meaning 2- monday) and so on

Used to live near Times Beach and drive by it all the time. It was super creepy.

Sam was robbed. Soduku barely has anything to do with numbers. It doesn't even need to have numbers in it at all. Sam's fact was completely about mathematical equations exclusively involving numbers! Sorry, Sam. In my opinion, this happens to you a lot.

Sam had a point from the Science Poem, Sam and Ceri tied in Truth or Fail, and Ceri got a point from the Fact-Off. They tied 1-1 in the end

my dive instructor when I was getting certified nearly a decade ago, actually advised we keep a bottle of vinegar in our dive bag specially for jellyfish stings. Good to see it wasn't another myth.

Can I just say that I really don't like Rhyme Time ^^' First of all, as a non-native English speaker, it's just a bit frustrating because I find it too hard, I'm never as fast as Ceri or Sam. But more importantly, it just doesn't give us any good science facts, it's just these rough, sort of funny, almost-rhymes and I don't really see the point of a language game when we already have the science poem at the start. It was fine a couple of times but I really wish we would get more fact-based games again ^^
