Calculate Pi in 10 steps without Guns, only Zombies!
Step 0: Kill a zombie by removing its head or destroying its brain. In a pinch you can lure one up high and shove it to the ground below.
Step 1: Detach one of the bigger bones of the arm or leg. If you have access to a cooler or are far enough north or south you may use the whole frozen zombie.
Step 2: Create your unit of measure. Detach a small straight segment of zombie -- the little bone at the end of the hand or foot will work. This will be our Zinch.
Step 3: Spin the larger zombie part while anchoring one end to create a circle of blood upon a flat bit of ground.
a. If the ground is uneven and you have only the corner of a wall, stand the zombie part in the corner and let it fall over to create a quarter circle arc.
b. Repeat 3a if you have a flat wall but no corner, falling the other direction to create a half circle.
Step 4: Place the Zinch on the edge of the whole, half, or quarter circle. Count the number of Zinches along the perimeter of the circle or arc.
a. For a quarter circle arc multiply this zinches by 4.
b. For a half circle arc multiply the zinches by 2.
Step 6: Count the number of Zinches of the larger zombie part. This is your Radius.
Step 7: Calculate Pi using the Radius and Circumference from step 4:
Circumference = 2 * Pi * Radius;
Thus:
Pi = Circumference / (Radius * 2).
Step 8: For accuracy, each Mathematician present should repeat the above with a different zombie / zinch then average your values.
Step 9: Congratulations! You have managed to distract all of the other Mathematicians long enough for them to be eaten by Zombies!
Step 10: Enjoy rebuilding society using the superior Tau constant!
There are Tau radians in one circle
Tau = Circumference / radius
