This is the 13th episode of The Show About Science, and people with triskaidekaphobia might be afraid to listen. Triskaidekaphobia is an extreme superstition regarding the number 13. In this episode, I talk to Stuart Vyse, a behavioral scientist, teacher, and writer. Stuart explains the science behind superstitions and phobias - so don’t be afraid to press play. A big big thanks to my Mom for recording this episode. “Triskaidekaphobia” by Jimmy Sutton’s Four Charms is available at http://www.histylerecords.com/four-charms/

When I was 2, one of the first science videos I ever watched was by the Amoeba Sisters - two amorphous amoebas that teach science. I think the topic of that video was viruses. I played it over and over and over. Then I watched the next one. Fast forward 3 years and here I am talking to Brianna and Sarina (the two real life sisters behind the Amoeba Sisters). How cool is that!!! In this episode, we discuss mitosis, DNA replication, viruses and so much more! You can watch all of the Amoeba Sisters videos on youtube (https://www.youtube.com/user/AmoebaSisters) or on their website (http://www.amoebasisters.com/).
