Readers looking for some educational entertainment might find the YouTube series It's Okay to Be Smart to be just the thing. Launched by PBS Digital Studios in 2013, this web series is enthusiastically hosted by Joe Hanson, a molecular biologist by training with a doctorate from the University of Texas at Austin. Here, viewers will find dozens of fun and upbeat videos exploring all manner of curiosities and scientific topics, such as why cereal tends to either clump together or stick to the edges in your cereal bowl, whether it's true that everyone has a doppelganger, and how fire ants became so widespread in the southern United States. The channel's main page is helpfully organized into numerous categories. While biology-related topics are heavily represented, visitors will also find videos on physics, earth science, and astronomy. Episodes are typically between 5 and 12 minutes in length, making them suitable for classroom use, and the videos' descriptions frequently include a bibliography of sources or links to additional information.
