A physicist, an engineer, and a statistician go hunting...
The three see a buck a little distance away.
The physicist makes a quick, back-of-the-envelope calculation, assuming an ideal bullet and neglecting wind resistance, and then fires. The bullet lands 10 meters in front of the buck.
The engineer has been doing his own calculations, adding in wind resistance and adding a fudge factor to include wind variations, Coriolis forces, and other, unknown variables. He fires, and the round lands 1…
