The Arch Never Sleeps - for iPad/Mac/PC: Recent Episodes
The Open University
It has been said that arches never sleep, that they are almost living in the way they adapt to change. Using case studies of Ely Cathedral in England and Chartres in France, the tracks on this album examine the way in which the design of arches developed in the early middle ages, and use mathematical models to explore some of the problems faced and overcome by the stone masons. This material makes up part of the course MST209, Mathematical methods and models.
