Math Seminars: a big list of online mathematics talks

One positive effect of the various lock-downs in place around the world is the sudden emergence of massive numbers of online seminars and talks. The site Math Seminars, developed by a team at MIT and currently in beta, holds a list of upcoming one-off talks and seminar series.

COVID-19: moving my maths lecturing online, week 1

I teach maths at university. Last week, I moved to online delivery, in something of a panic. I am writing to share something of how this went.

Katherine Johnson (1918-2020)

Katherine Johnson

Mathematician Katherine Johnson has died at the age of 101. She calculated rocket trajectories and orbits for early NASA space flights, including the missions that sent the first American in space, the first American to orbit the Earth and the first men to walk on the Moon, as well as contributing early work on the Shuttle program and many other areas. She was one of the women featured in the book and film Hidden Figures in 2016.

The smallest unique Cheshire Cat

At the MathsJam annual gathering, one of the many activities attendees can participate in is a competition competition – entrants each come up with a competition and submit it into a larger competition, other attendees enter each of the competitions within the competition competition, and the organisers get the chance to make long and confusing (but strictly correct) announcements that contain the word competition a lot of times.

This year, we decided, after a spectacular last-minute MathsJam bake-off entry failure on the behalf of Katie, to enter a joint competition into the competition competition. Inspired by the ‘lowest unique answer’ style of competition, which has previously featured in various MathsJam Competition Competitions (and our recent lecture on game theory) we came up with an idea – what about a competition seeking a unique entry in a non-ordered set?
