Liberal Arts

20140719_090058IMG_1323The next Ordered Universe symposium will take place at Bishop Grosseteste University, in Lincoln, 8th-10th April, 2015. Jack Cunningham and his team at BGU will be taking the helm for the symposium, dedicated to the two earliest of Grosseteste’s works, a second series of sessions on the De generatione sonorumOn the Generation of Sounds, and a first outing for the mysterious and rather beautiful De artibus liberalibusOn the Liberal Arts.

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!

The Medieval Big Bang and the Sky at Night

The Ordered Universe/Durham Grosseteste project work on the treatise on light is this month featured in the BBC Magazine, Sky at Night, dedicated to all things astronomical, in an article written by Paul Cockburn. Gasper, Panti, McLeish and Bower were all interviewed and feature in the discussion of Grosseteste’s expanding universe in his radical, anomalous, revolutionary?, exposition of Aristotle and the question of the extension of body. Get your copy now! We are featured on pages 69-73, including a lovely commentary on the project by Richard Bower, on the beauty of the treatise and the alternative rationality of this medieval view of the universe.

The Medieval Big Bang will feature at the FIDEM congress in Porto, and will be the main focus of the project’s publication programme this calendar year.
