In response to the Oct 22nd posting, The Sun and the Climate, the mathematical explanation of Bode's Law may actually have already been worked out – by Robert Bass. He was due to speak at the SIS conference on 'Cosmic Catastrophes – Asteroids, Comets and Planets' held at Fitzwilliam College in Cambridge in 2007, in order to present his explanation of the Titus-Bode Law. Unfortunately he had to withdraw and we never learnt what it was. His theory was published in a refereed journal but Bass has said, and confirmed, that he made a fundamental error, which the referee missed as well. Any mathematician seeking to find an alternative explanation would be well advised to visit the Bass web site at http://www.innoventek.com/science and read article 32, 'Dynamic Origin of Bode's Law' in order to appreciate how difficult the problem is.
