Table 1: m IDitotic calculation*
m Rigatoni length (cm): m 5.3 p m
m Rigatoni outer diameter (cm, from Figure 4): m 1.7 p m
m Rigatoni cylinder surface (length * outer diameter * π), m cm2: m * 3.14156 * p m
m Rigatoni cylinder ends ((outer diameter/2)2 * π * 2), m cm2: m 1.7 2 / , * 3.14156 * 2 * p m
m Rigatoni total surface (surface + ends), cm2: m + p m
m Based on the estimated clearance of insertion, 0.15 cm,
m using the clearance as the radius of a circle
m into which the insertion must be made,
m the target for insertion from either end is m (2 * π * clearance2), m cm2: m
0.15 2 / , * 3.14156 * 2 * 3 d p 1 d m
m Actually the target is much bigger because the tip m of the
m Penne Rigate m is pointy. m It is better to use the inner diameter less the m
m Penne Rigate m tip, which is roughly 0.3 cm (Figure 4). m
m So compute: m (2 * π * (inner diameter - tip)2), m cm2: m

m Probability of one insertion during a random encounter
m is the target area divided by the Rigatoni total surface: m
~ / n p n m m
m Fraction of observed insertions (Figure 2): m 0.6 p m
m Number of available Rigatoni: m 40 0 d p m
m Estimated total number of insertions (40 * 0.6): m * p m
m Probability of all these insertions by random encounter: m n # s ^ p m m
m *This calculation was performed according to standard m Intelligent Design (IDiotic) methods. m
m It was performed using the m calc program with input m idiotic.calc. m
