The three videos below were recorded during the first COVID-19 lockdown in the UK (March-May 2020), largely to experiment with recording on various platforms. They can also be found on this YouTube channel.
NBMPS58, Edinburgh, April 2020 The 3D Plaquette Ising Model:From Random Surfaces to Fractons (mp4)
This commits the cardinal sin of being too long, practice makes perfect. Recorded on a mac with cmd-shift-5.
Old - content from way back (2006) Wealth Condensation as a ZRP (mp4)
This has the considerable merit of being shorter. Recorded on Chrome OS with Screencastify.
Prehistoric - content from way, way back (1985) Why (your) mass isn't gauge dependent (mp4)
Also shorter, which is good. Recorded on Ubuntu (20.04) with Screencastify.
