Happy First Day of Summer! Watch Bill Nye Explain Seasons

Consider the Following

One of the most memorable moments of my Astronomy 101 class was when the professor played this video for us, of graduating Harvard students who could not correctly explain why we have seasons. Of course, since that video was filmed in the ’80s, I’m sure we’ve worked all of that out now with Bill Nye the Science Guy, right?

Happy Summer!

Susana Polo thought she'd get her Creative Writing degree from Oberlin, work a crap job, and fake it until she made it into comics. Instead she stumbled into a great job: founding and running this very website (she's Editor at Large now, very fancy). She's spoken at events like Geek Girl Con, New York Comic Con, and Comic Book City Con, wants to get a Batwoman tattoo and write a graphic novel, and one of her canine teeth is in backwards.
