Setting and Scene
Lecture theatre, talk during conference of specialism
Speakers, academics, students
Presentation of new work for critique, publication, information of other participants and discussion
Talk with scattered questions, followed by formal Q&A at the end
Technical language, though at the beginning the presenter emphasises that “this talk will be highly non-technical”
Frequent diagrams, often very roughly drawn in a very childlike way, which still appears to be sufficient for precise understanding in the context. This includes reference to a “two-legged fish“, shown by a rather strange diagram, saying that
n^2 is not allowed because of the two-legged fish
Two measures of a property were given as
Bending energy or Willmore energy is a measure of how bent it is
first a verb, then a name
Some reference was made to applications in biophysics, Bensimon & Matz, 1992, shapes of vasicules
Some metaphorical language used, including
taking a walk along this curve
Here you arrive at the same point, here you arrive at different points
Push the blue curve into this red curve here
this guy here has area 0
this evil guy here…
and a diagram characterising a manifold as a globe giving it a North and South pole.
Often presented ideas as part of a narrative, either imagined as above, or in the form of an anecdote about the process of doing the research presented, as below:
We had to understand which case was which because understanding that would give us a good idea of whether we could compute this
He speaks of
[Looking] at my surface from distance T
The phrasing of ‘look at’ a mathematical object is interesting, as most of its significant properties cannot be made physical and are depicted symbolically.
“The behaviour of a charged loop of strings is a traditional subject for tea-time speculation” – Freedman – Ho-Wang 1994
This appears to be some kind of a mathematical joke involving T-time, obscure to non-mathematicians.
No interruptions except short questions for clarification until Q&A, when participants raise hands to ask longer questions
Few people understand the proof; there have been efforts to find another.
