Free-Body Diagrams
In this video Paul Andersen explains how free-body diagrams can be used to solve kinematics problems. The only two parts of a free-body diagram are the object and all external forces acting on the object. Numerous situations are...

TED-Ed: Why are human bodies asymmetrical? - Leo Q. Wan
Symmetry is everywhere in nature. And we usually associate it with beauty: a perfectly shaped leaf or a butterfly with intricate patterns mirrored on each wing. But it turns out that asymmetry is pretty important, too - and more common...

Why Do Things Look Darker When They're Wet?
It's kinda embarrassing when you spill stuff on your shirt and it makes a stain. So you might as well understand the science behind it, so at least you can act all smart and explain it to people.
