SciShow Tangents — Science
SciShow Tangents

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.

Show notes

Things get a little weird this episode, and by ‘little’ I mean very little!

One thing I learned in this episode is that everything in the universe is touching each other, yet the particles in your body never truly touch! Mama Mia!

Well anyway, I hope you enjoy it! Thanks for listening!

Hearts Feb 11, 2020

Show notes

This Valentine’s Day, what could be better than cuddling up with someone special and listening to the Tangents Crew talk about various medical procedures in gory detail! Pucker up!

They say the fastest way to a man’s heart is through his stomach, but I think if you ask a doctor they would probably say that’s wrong! But what do I know?

Meat Feb 04, 2020

Show notes

Meat... seems pretty simple on the surface, but what do we really know about it? Like.. are living things made of meat? Or is meat only meat once it's being eaten? What was the first meat? What was the first thing to eat the first meat? Is eating prehistoric meat a good idea? Do we find the answer to any of these questions in this episode? I can't remember, frankly, but probably a few.

Running Jan 21, 2020

From diet, to shoes, to movement efficiency, people devote their lives to researching and perfecting the art of running. Meanwhile, cheetahs run 75 mph and they sleep all day. No fair!
