Cool to see this happened at Caltech :)
It's interesting that the number of crossings is independent of whether L/W is less than or greater than 1, but the probability of crossings is equal to 2pi * L/W only in the short case. This makes sense since in the short case the noodle can at most cross a single line.
> The formal argument for this is known as Girard's Paradox. It is related to a better-known paradox known as Russell's Paradox, which was used to show that early versions of set theory were inconsistent. In these set theories, a set can be defined by a property.
