JF Ptak Science Books Post 2095
I am probably not understanding this wonderful effort1 by the dead Lewis Carroll, establishing a new algorithm for doing long division. It came into view while I was looking for a paper in Nature by A.A. Michelson on his analog computer, the harmonic analyzer, a fantastic device that he used to help measure the speed of light back in 1898. Carroll (as Dodgson) appeared just a few pages away2; his obituary appears not much after the division article, thus making the paper the last of his career here on Earth.
It is a very interesting effort, and it perhaps is even brilliant and of a wonderful construct, but the bottom line is that it makes the process of division harder to do--perhaps it is mire understandable as a process, but the process itself is decidely not a preferred one. Perhaps it is appropriate for his last work to have been on mathematics, since the majority of his 20 published books relate to mathematics or logic.
I've reprinted the entire article, below, as well as a list of his mathematical efforts.
