As a mathematical retard for whom numbers merely connote interesting letter-like detached shapes, I enjoyed the note in comments about the "Discovery Channel Effect."
Someone explained to me that is why we have cruciate ligaments in our knees: for when we have to run in tight circles, or other things that make the legs have different speeds. Whenever you hear of an athlete blowing out their ACL (anterior cruciate ligament), they blew their differential!
I've seen that one before and the demonstration does a great job of explaining a simple solution to a very complex problem. More impressive to me, is think about the guys that sat around with pad and pencil and figured that out from scratch.
That was a great explanation. I took a differential cover off when I was first working on cars and spent a lot more time than that figuring out how it worked.
For centuries the ox-carts of India had square axles that made the outer wheel hop when going around a corner... What did it take to lose such knowledge, or to never have gained it?

For me becoming an EE was the result of a lot of cool 'future tech' from Star Trek and other shows, as well as inspirational sources like Heathkit.

What a great demonstration - after all these years, I understand this!!!!

kx59: I kinda think it was less pad and pencil and more of a hands-on type of thing.
