Learning on Purpose

This is coming from my last post.

What is the last thing you learned on purpose?

For me it was about Kline Fogleman Airfoil.  The KF airfoil is a revolutionary airfoil first developed some time in the 70's.  It was used on a world record holding paper airplane but it was laughed at by aviation experts because they did not understand how it work.  It involves putting a step about midway on either the top or the bottom of a wing.  The step creates some turbulence which then generates a surprising amount of lift.  Right now it is getting a lot of attention by remote control model airplane enthusiasts.  (That is where I picked up the idea.)  YouTube, Google, a couple of podcasts, and many discussion forums were my partners in my research.

A challenge:  What was the last thing you really learned on purpose?  I don't mean something that you learned in passing.  I mean something you went out of your way to find out about.  Not because you had to but because you wanted to.  I am passing the challenge on to a few of you (and anyone else is welcome to join in).
