When Life Throws You A Curveball
Found this on Deadspin today. Awesome optical illusion, that explains why a curveball doesn't really curve, but looks that way to a hitter.
An interesting part of this illusion is the fact that if you focus on the opposite side (not the side with the blue dot), then the ball looks straight. I wonder if the key to hitting a big league curveball is simply focusing your eyes away from the ball, staring at the space opposite the curveball's spin. I'll have to try it next time I'm in the major leagues.
