“ken” and “milliken”

The story that Robert Millikan’s colleagues jokingly called a unit of talkativeness a “ken,” and its thousandth a “milliken,” is not confirmed by reliable sources located. I found no such term in accessible institutional biographies of Millikan, archival material, or scholarly literature. It should therefore be treated as an unverified joke, not a real unit or a documented anecdote. The illustration is AI-generated.
