Helix

While working on a helix (LINK) related problem at work today I came across this definition:

"A helix is a curve for which the tangent makes a constant angle with a fixed line. The shortest path between two points on a cylinder (one not directly above the other) is a fractional turn of a helix, as can be seen by cutting the cylinder along one of its sides, flattening it out, and noting that a straight line connecting the points becomes helical upon re-wrapping. It is for this reason that squirrels chasing one another up and around tree trunks follow a helical path."

The squirrel analogy is 100% true. We have millions of the little shit-monkeys in our back garden and I have often see them do the helical chase around the oak tree.

Squirrel-centric analogies are key to my survival in the modern workplace.
