Wow, this seminar is really relevant for what’s happening here - cat’s cradle, music and weaving… Several sessions will be dedicated to the relation between military culture and math ; also interesting, the topic of “practical geometry” in frieze design throughout the world (highlighting Celtic culture).
If I’m not mistaken, this is the continuation of a similar seminar from last year, perhaps even before then. I happen to be a PhD student at EHESS. I’m not following the seminar, but happy to help anyone interested to dig into this.
