Welcome to the 30 Day Challenge for July, where we’ll be looking at the STEM fields: Science, Technology, Engineering, and Math. I originally conceived of the as the Science & Math Challenge so those two categories will get more attention, but we will touch on all of them.

Today we want to talk about what sci-fi gets wrong. Yes, it’s finally time to embrace your inner Neil Degrasse Tyson and share the worst science and math flubs you’ve been subjected to throughout your media-consuming life. As with yesterday, all types of media are fair game.

Bonus: When was the worst science used to the best effect?
