An unannounced change in zoom made it impossible to use prepared visual material, so this was a "talking-head" presentation.
Fortunately, the youtube recording was edited (at Tubingen University) to replace the original "small" talking head, with a larger talking head!
The full episode is available on the BBC Springwatch web site.
Talk at Tubingen colloquium 2 Jun 2021
About 72 Minutes.
An update to Zoom had prevented me using screen-sharing for the presentation. Several attempts to get zoom to switch to screen-share mode caused zoom to crash, so I had to give the presentation simply by talking, without using my prepared materials.
So notes, diagrams, videos prepared for the talk could not be displayed, and it had to be an unprepared "talking-head" presentation, including much hand-waving!
After a break there was a discussion in which a few people asked questions or made comments and I responded. Most interventions were quite long, or provoked extended discussions. There were various pauses and false starts that have been edited out, for the sanity of online viewers. The resulting edited recording of the discussion (reduced to about 68 minutes) is available here (installed 9th Jun, replacing an earlier .mp4 file that did not work in the firefox browser): Video of discussion following the talk (.mp4 format)
(Important correction: at around 1:01:52 I mention a task often used in talks by Geoffrey Hinton, namely pointing at locations of vertices of an imagined cube with one vertex on a horizontal surface and the opposite vertex vertically above it. Unfortunately, in this talk I made the mistake of talking about where edges are, rather than where vertices of the cube are.)
The planned presentation was intended to make use of items on this web site:
But that was impossible when zoom's screen sharing facility was not working. So the talk required a considerable amount of unplanned improvisation!
