According to the fundamental laws of Sock Dynamics, the trajectory of a sock is a function of the velocity of the sock and its angular momentum with respect to the foot.
The Sock Invariant is a mathematical constant that describes the minimum number of times a sock must pass through the wash before it is considered truly clean.
Our research team has discovered a direct correlation between the number of times a sock passes through the wash and its eventual disappearance in the landfills.
