In this article Art Shapiro and two Bucknell University graduates created an illusion that fools the brain. There illusion shows a spinning ball, when you watch the ball directly it moves in a straight line, but when you see the ball from the corner of your eye the spinning of the ball tricks the brain into thinking that the ball is sharply curving. This study may explain why batters in baseball can have so much trouble hitting the pitch. Knowing this you could possible improve your batting average. This study could help us understand more about sensory perception and the more of the brain since it is so complex..
