Balls roll down a nail board into parallel chutes
forming a probability curve similar to the distribution of molecular velocities. |
1A20.10a |
Gaussian curve: Probability Board |
1000's of small ball bearings are funneled down through an array
of posts to form the Gaussian Curve. (Must be retrieved from the Physics
Exporitorium.) |
