Abstract

The evolution of drift with time at a plane normal to the passage of a body from far right to far left is investigated. It is shown that the measurable part of the drift volume as a function of time is uniquely determined, and that the indeterminacy of Darwin's drift integral simply does not matter to the physical world, in which there is a Darwin theorem stating that the drift mass is equal to the added mass. The method for determining the shape of the drift surface is also given.
