  • We here on SciShow Tangents may have the market cornered on science podcasting, but that doesn't mean we know everything. Put us in a lab, and we're like fish in water! But put us in a library, with all those big tall shelves and the Dewey Decimal System, and we're like a fish not-in-water! So we called in our friend, podcast, theologian, and noted book-reader Vanessa Zoltan to help us learn more about books!

    Learn more about Vanessa and her myriad of projects at her website, and follow her on Twitter @vanessamzoltan!

  • When, in nature, two little guys are benefiting off each other one way or another, we call that symbiosis. But, if you think about it too hard, you start to realize that everything in nature is benefitting off some other thing in nature somehow and come to the conclusion that all of Earth is a giant symbiotic relationship! To that I say: simply try not to think about it too hard!
