**Summary:** I'm building a calculus course from the ground-up focused on *permanent intuition*, not the cram-test-forget cycle we've come to expect. Interested? Sign up for the [mailing list](http://betterexplained.com/articles/betterexplained-email-list/) to get news about the pilot, launching early August. The learning principles below will guide its development.
I usually avoid current events, but recent [skirmishes](http://devlinsangle.blogspot.com/2012/07/cant-we-all-get-along.html) in the math world prompted me to chime in. To recap, there've been heated discussions about math education and the role of online resources like Khan Academy.
I've just added a new feature to the site: an Aha / FAQ section for each article. You can add an aha! moment or question, and vote / discuss them individually. This extends [aha.betterexplained.com](http://betterexplained.com/articles/share-your-insights-aha-betterexplained-com-beta/), making mini-posts for key ideas in an article.
