Grosseteste meets York Stained Glass Studies

Bishop_Robert_Grosseteste,_1896_(3x4crop)Tom McLeish was invited last week (November 1st) to hold a seminar on Grosseteste’s colour science  with the University of York’s History of Art Department’s Stained Glass Studies Group.  So here (right) is a stained-glass representation of the Bishop to start with.

Tom, an original member of the Ordered Universe project right from the very early days in Durham, has recently joined the University of York as its new Chair of Natural Philosophy.  Although based in Physics, the role has time allocated to the

Kings Manor of the University of York, the home of its Centre for Medieval Studies

University’s long-standing Centre for Medieval Studies, as well, which is now a partner of the project. The Centre is accommodated in Kings Manor, the former abbot’s house of St. Mary’s Abbey (now ruined) close to the Minster, Museum, Library and Art Gallery in the centre of the city.

The natural starting point for the Kings Manor seminar was Grosseteste’s De colore, his treatise, probably from the mid 1220s that develops his natural philosophy of light into a theory of colour.  Early in the Ordered Universe project’s life we had studies this jewel of a treatise, and found it to be structured in a highly mathematical way. It constitutes the first description of an abstract three-dimensional space for colour.Dimensions of Colour book_ These insights, together with a fresh edition and translation and interdisciplinary commentary, formed the first ‘pilot’ publication from the project, Dimensions of Colour, back in 2013. in only 400 Latin words, Grosseteste carefully identifies colour as the effect of light incorporated in a diaphanous medium, and describes three ‘axes’ along which colour can vary independently. Crucially, two of these depend on properties of light and one on the material within which the light dwells – its ‘purity’ or ‘impurity’. This is turn is related to the quantity of ‘earthiness’ (earth is the only non-translucent of the four Aristotelian elements). The final paragraph of the treatise contains an invitation to try out making colours with different lights and materials, and is one of the pieces of evidence pointing to Grossteste’s involvement in the very early stirrings of experimental tradition.

York stained glass scholar Sarah Brown, who led the scholarly work behind the recent 10-year restoration of York Minster’s Great East Window, was led to think about glass-making right away by this paragraph. Might Grosseteste have witnessed the manufacture of glass?  If so this would not have been in England, but in northern France. Does a thread from light through colour and glass constitute another line of evidence that leads to a presence for him in France in the early 13th century?

The discussion also moved onto lenses and lens making in that era, of which no doubt there will be more news on this blog at a future date…

 

The Uncertainty Principle – The Ordered Universe at Pembroke College Access Week 2018

A guest post by Thomas Henderson, 2nd year history undergraduate at Durham University, who has spent this week as an undergrad mentor and tutor at the summer school

After a year’s programme of seminars and a residential Easter school in Durham, the OxNet-Ordered Universe access scheme has reached its climax with this week’s residential summer school at Pembroke College, Oxford. The sixth-formers from Sunderland have joined with others from OxNet schemes in Manchester, Cheshire and London, as well as students from rural India supported by the Karta Institute, for a programme of seminars, lectures and tutorials aimed to provide an insight into the realities of university study.
The entire summer school was kicked off on Sunday evening by Dr Peter Claus, Pembroke’s Access Fellow, and Dr Sigbjørn Sønnesyn, who introduced the themes of the school’s title: ‘Through a Glass Darkly’. His diverting lecture urged the students to embrace the limitations of human knowledge, and its attendant feelings of uncertainty and confusion, as the precursors of investigation and exploration. Taking its cue from the Ordered Universe project, the school is designed to challenge the way the students conceptualise knowledge, and to encourage them to think in a way unbounded by A-level mark-schemes or conventional divisions between disciplines.

At this half-way point, it is clear that the sixth-formers have taken these words to heart. Their eager inquiries about the realities of university life and applications (making the most of their undergraduate mentors) have been matched by affirmations of their intentions to apply to elite universities. A visit from journalists from the BBC Look North served to focus them further. In their academic work, they have been just as engaged and stimulating.

The Ordered Universe strand is focused on colour, light and rainbows. Work on these topics has included two of the project’s signature collaborative reading sessions, of De iride and De luce, led by Sig Sønnesyn, and a workshop on the science of rainbows with Joshua Harvey. These sessions have seen students enthusiastically discussing and disagreeing with each other over (among other things) the nature of rainbows, the problems of perception and whether a sunrise can exist without somebody to observe it. We look forward to what they will produce come Friday!

Science, Wonder, and Imagination: an Update

IMG_2383 Excitement is building as months of planning, hard work, and preparations are about to come to fruition. The programme for the upcoming conference Science, Wonder, and Imagination – Robert Grosseteste and His Legacy is now very close to being finalized. The conference, organised by The Ordered Universe Project in association with the International Grosseteste Society, will take place at Pembroke College, Oxford, on April 3rd to 6th, and we are very excited about the range of topics covered by our line-up of speakers. The works of Robert Grosseteste will form points of departure for scholars from a great variety of disciplines, including philosophy, theology, cutting-edge science as well as history of science, education studies, and broader historical disciplines; but also for explorations of the aesthetic inspirations to which Grosseteste’s works can give rise. Judging from the titles and abstracts, speakers are eager and willing to look beyond their own disciplines and communicate across disciplinary boundaries, and we are very much looking forward to the discussions and conversations that such a wide variety of approaches can engender.

The conference programme has been constructed around the pillars of four keynote papers, to be delivered by

Professor Simon Oliver, Van Mildert Professor of Divinity, Durham University and Residentiary Canon of Durham Cathedral;

Professor Suzanne Conklin Akbari, Professor of English and Medieval Studies and Director of the Centre for Medieval Studies, University of Toronto;

Professor Jim Al-Khalili OBE, Professor of Physics and Professor of Public Engagement in Science, University of Surrey;

and Professor John Milbank, Professor in Religion, Politics, and Ethics, University of Nottingham.

We are very grateful to our keynote speakers for accepting our invitation, and we look forward to having our horizons broadened by their unique perspectives.

The Ordered Universe teams at Oxford and Durham have worked very hard to make this conference possible, and we are deeply grateful for their labours. Watch this space for more updates and reports!

The Ordered Universe Project and the Being Human Festival 2017: Oxford Edition

Joshua Harvey, a DPhil Candidate in the departments of Engineering Science and Experimental Psychology at the University of Oxford brings us a report on his time as a ‘Lost Late’ exhibitor at the Oxford strand of the Being Human Festival 2017.

Oxford Being Human 2017 1

Last Friday saw 1,500 people of all ages congregating under a fabulous mix of lights, music, research, and dinosaurs. The event, ‘Lost Late’, formed part of the national Being Human festival, hosted by both the Natural History and Pitt Rivers museums in Oxford. From 7pm until late into the evening, visitors could stroll through the two connected museums, which had been utterly transformed into a realm of discovery, from mazes to archaeological dig sites.

The Ordered Universe of UBC, Vancouver

Friday last saw the Ordered Universe project hosted at a very civilised Dinner-and-Lecture evening at St. Johns College, University of British Columbia, in Vancouver. medbigbangvancouver

Tom McLeish, Co-investigator of the project had been in the Vancouver area all week on a lecture tour organised by the Canadian Science and Christian Affiliation (CSCA). After four events based around his book Faith and Wisdom in Science, as well as several science seminars (in Simon Fraser University and UBC itself), this last event, as all others organised by long-suffering and ever-kind host Gordon Carkner, focussed in on the unique collaboration of humanities scholars and scientists digging deeply together into the natural philosophy of Robert Grosseteste.

A Medieval Big-Bang Theory: An Interdisciplinary Tale, began with a personal story about Tom’s first encounter with Grosseteste, from Jim Ginther’s regular HPS seminars at Leeds in the 1990s, then his astonished reading of the treatise on light, the De luce, the summer before his move to Durham in 2008, where he met up with medieval historian and theologian (now project PI) Giles Gasper.  The seminar then covered the technical content of Grosseteste’s light-expanded cosmos, and the corollary of his material physics of light – the theory of colour in the De colore and the De iride (on the rainbow).  The invited audience of students, faculty and members of CSCA had enthusiastically reserved 2 hours for the  event (!), so it was possible to go into some detail on the delicate interplay of scientific analysis, textual and philosophical work.

As ever, the participants were surprised and delighted to hear about the new science that the project has produced, as well as its insights and scientific commentary on 13th century treatises.  Tom managed to fit in both the three-dimensional mathematical structure of the colour space Grosseteste constructs in the De colore, and the new ‘rainbow mapping’ of colour space that this, accompanied by work on his De iride inspired, later published in the Journal of the Optical Society of America.

FaWis_450Perhaps the most satisfying aspect of the context of this event, however, was the invitation from the hosts to situate the project findings in the twin theological contexts of Grosseteste’s day and ours. Our medieval polymath tends to stick to science in his science texts, but from other important works such as the Hexameron, and the Commentary on the Posterior Analytics, we know that he has a developed theological purpose for studying nature to the end of understanding it.  He sees the process of induction from our sense data and intellect as a long and slow process of reawakening that insight and close relationship with nature that humankind was created to have in the first place, but lost through the turning away from its Creator in the Fall.  At this point the medieval science work dovetails into the thesis Tom has been developing in Faith and Wisdom in Science (click though for book and blog) for a healthier modern narrative for science.  The idea of science as the means to a healed relationship with nature strikes important late modern chords, as well as resonating with the philosophy of earlier ages.  It’s an old story of purpose that we have forgotten and need to remember.

Questions were very rich and varied – including one that the questioner would have liked to pose to Grosseteste himself: ‘Why did God allow the perfection of the spheres to stop at the Moon, and not complete all the way through the cosmos?‘ Our Oxford Master was fond of alternative histories – he tackled the question of whether there would have been an incarnation without a Fall, after all.  But what would he have made of a universe of crystalline spheres ‘all the way down’ (which is precisely what one of Prof. Richard Bower’s early simulations of his cosmogenesis physics in the De luce produced!). To be discussed…[Giles says: ‘Perfectness can’t re-create perfectness, otherwise it wouldn’t be perfect…’]

The Ordered Universe Project Returns to (one of) its Roots

I received an invitation last year to give a seminar that was impossible to turn down.  Every Wednesday afternoon the Centre for the History and Philosophy of Science at Leeds University holds a proper academic seminar – 3.15 to 5pm, giving plenty of time to expound an idea as well as have it comprehensively discussed.  I had to go – for it was in this setting, regularly taking time of from the Physics department during the years I was professor there, that I first learnt about Robert Grosseteste.

Gravitational Waves and the Cosmic ‘Sonativum’

Only an Ordered Universe blogpost could deserve a title like that.  We cannot let a discovery of such reach, beauty, conceptual depth and powerful simplicity (yes indeed) as the LIGO team’s announcement this month of the first detection of gravitational radiation go without a celebratory comment from the Robert Grosseteste club here.

Robert did, after all, engage in the magisterial De luce in the work of imagining the entire cosmos, and indeed in the propagation of waves across it in the process of its first formation.  Another centrepiece of his thought world was the connection of the universal with the present and microscopic.

Ordered Universe goes Down Under

As Giles has already indicated, I have been enjoying a lecture tour over the last week in Australia and New Zealand. Originally catalysed by the Faith and Wisdom in Science book (which does have some Grosseteste stuff in it), and an invitation from the Theology department of Otago University here in Dunedin – particularly their Centre for Theology and Public Issues (CTPI), it grew into a series of visits to departments of physics, chemistry as well as interdisciplinary centres and theology departments in Melbourne,  Aldelaide, Brisbane, Sydney, Queenstown, Dunedin and Wellington.  In Australia my host organisation was ISCAST, a network supporting thinking and public engagement of Christianity and science.
