Why universities are starting to re-evaluate their academics' travel

The tertiary sector’s air miles may be dominated by a small number of hyper-mobile senior academics, but studies show virtual conferences can improve diversity, career development and emissions.

@rcorless - it'll be good for us academics to fly around less - especially the more successful ones who do most of the flying. I've stopped accepting most invitations for air travel, especially for invitations that involve staying somewhere for less than a month. I feel happier.

@johncarlosbaez yes, I can see that. But! One of the perks of academia that people are *the most* jealous of is our travel. It's incredibly broadening. But your point about staying longer is very good and has been my habit whenever possible for a long time now, especially when I go a long distance. I was just in NZ for a month, for instance. My trips to Spain are typically a month or two months long nowadays. But not everyone can do that.

I will miss it greatly. But I have been lucky and shall not complain (he says, steps from the beach in Tahiti, good gravy). I lament the loss for younger colleagues, though.

@johncarlosbaez The academic part of my trip is over but I am going snorkeling in the Tuamotus with David Stoutemyer (one of the authors of Derive). It's possible that we will write another paper together while we are on the boat, but that's not the purpose of the trip. Also: No grant money is being used for this part of the trip!
@rcorless @johncarlosbaez The Tuamotus! Years ago I found a book in the maths section of a second-hand bookshop called "The String Figures of the Tuamotus".
It's interesting, and shows you how to make all sorts of patterns, but no idea how it ended up in the maths section!
@rcorless @johncarlosbaez I've found the book!
@christianp @rcorless - have fun in the Tuamotos, Rob. And maybe you can find some of those string figures. What were/are they used for? Just for fun, or something practical too?
@johncarlosbaez @christianp I had never heard of them, and I shall look out for them! What an interesting find!
@johncarlosbaez @rcorless the preface says, "the making of these figures, called fai, was then still an integral part of the Tumatoan culture - a means of ready communication and establishment of friendships; an illustration of episodes in the careers of traditional characters with accompanying chants of myths, legends, and folk tales; a demonstration of knowledge and skill; a provoking of mirth and thus also a dispelling of monotony."
@johncarlosbaez @rcorless (interpret this in the context that it's the recollections of a coloniser 40 years after he was in the Tuamotus)
@christianp @johncarlosbaez Apparently, I found the one person on Fakarava who still teaches the art. Sadly, we did not have time to discuss it much, and she was prepared for another cultural event (dancing, at which she was excellent) and not fai. Maybe next time!
@rcorless Interesting! I just rediscovered this thread; thanks for quoting that book, @christianp. Now I'm even more curious about the use of this art.
