Physics of De Luce Hots Up

Recent working meeting with Richard Bower, Hannah Smithson, Tom McLeish and Brian Tanner worked through the surprisingly subtle physics issues of balancing luminous drag and absorption as the celestial spheres crystallise out.
Another surprise is the strong effect of the initial matter distribution (following the original expansion). Well behaved universes of the Aristotelian type seem to require steep initial density distributions, though this requirement may be balanced by sufficient absorption within the shells. Would Grosseteste be surprised to hear that for his universe to work, the heavenly spheres need to possess only partial transparency to “lumen”?
Somewhere in there is not just a medieval universe, but a medieval “multiverse”. All possible numbers of planetery spheres – and other universes where the density goes chaotic and non-monotonic. The initial density profile looks important too … more when the movie comes out!

I am a very badly behaved academic. I know that physics is my 'core discipline' - it's a good one and I love it - but I trespass into interdisciplinary territory all the time. Brief bio: first degree and PhD ('84) at Cambridge topped off with a short fellowship at Emmanuel College, then lectureship at Sheffield ('89-'92). I started working seriously across the chemistry-physics fence there through polymer science (and visiting the marvellous Biblical Studies group which sparked my love of ancient wisdom literature). As Professor of Physics in Leeds ('93-'08) including 5 years as an EPSRC Fellow, I began to work with biologists as well. Some theological training as part of an amglican lay reader's course in the Diocese of Ripon made me think more about how science and religion both encompass and draw on all of human culture. So it planted the seeds of the new book 'Faith and Wisdom in Science'
