Content Update: October 2018 (US History and Government, Calculus, Partner Content, and more!)

In October we added some timely US Government content, including videos on the politicization of the Supreme Court, media and partisanship, and the changing role of the presidency. But if you’re looking for other topics we’ve got you covered too, don’t worry :) Challenge yourself with some new Differential Calculus videos and exercises, see some of the top submissions from the Breakthrough Junior Challenge, and then learn how Pixar gets its lighting right. And more!
