Is Brooklyn expanding?
Alan Turing was fascinated by the possible variation of natural laws in time. There is just a hint of this in his paper, "Computing Machinery and Intelligence," the source of the famous phrase "the imitation game." The subject, long at the intersection of science and philosophy, has recently started to become of practical interest.
Anyone can read Turing's paper, http://j.mp/1m1tat10n , which is freely available from its publisher. I recommend that all participants in this seminar do so beforehand.
