In this episode, Charlie remembers Euclid's Orchard Problem when his facial recognition program fails to find a match when searching for a renegade CIA agent. Charlie explains that when looking at an orchard from the sky, you can see all of the trees that comprise it; however, if you stand on the ground, the view is considerably different. Some of the trees block your view of others.
This activity explores ideas related to the Orchard Problem.
