I love clear explanations of complex things



I like this little video explaining how a differential gear works.  Whether you don't know what a differential gear is or you already know how it works, I recommend watching this little explanation from the 1930s.  I like how it moves through the problem and illustrates each step clearly.  Spend a few minutes watching and you'll understand it for life.

Original video is available here.
