Let's learn math! This video contains no math.

Let's learn the concepts behind vector math, and see if we can get a clear understanding in our heads. Then we can get the vectors to do what we want by simply telling the program to do what we want.

Today's specific example: bouncing a ball off a paddle. Reflecting a vector off a surface using simple operations and no math!

I do say 70% / 30% at one point, and that's wrong. I just had taken too many takes and was running on autopilot. It's a sine/cosine thing, so it's more like 70/70.
