ALT Photograph of the inside of a library with a curved white ceiling, wooden bookshelves and a blue carpet. There is a floor-to-ceiling window in the centre and two white banners with a red logo and the text 'Jesus College Cambridge' are either side of the window. Outside of these are two computer screens showing the title slide for a presentation with the text 'Walking in four dimensions'. There are people sitting around tables and two people standing at the front of the room, one of them (me!) standing behind a small desk with a laptop introducing the presentation.
