how long range locators work

[Elie]

An Engineer, a Mathematician, and a Physicist are tasked with building a fence for a Texan's ranch that encloses the most amount of area using the least fence. The engineer goes first. She builds a circular fence about 100m in diameter, and states that her design is the most efficient under the conditions stated.

With much handwaving, the Physicist proposes to build a fence around the equator of the earth, as the curvature of the 2D surface of the earth in 3D will enable more area to be enclosed per unit of perimeter. His design is thrown out for lack of practicality.

By this time, the Mathematician has finished thinking. The Engineer and the Physicist follow him to the very back of the Texan's property. He takes 4 short sections of fence, builds a tiny fence around himself, and says...

"I declare myself to be on the outside."
