Every third Saturday in November, the annual Ars et Mathesis day is held, this time it took place in Eindhoven. It always offers a symposium with an attractive programme, combined with the opportunity to be inspired by the work of the various exhibitors. Donors (https://www.arsetmathesis.nl/donateurs/) have free admission to the A&M day and are presented with the new yearbook upon admission.
At the meeting in Eindhoven, there were many exhibitors, including Henk van der Vorst, former professor of numerical mathematics, with his mathematical origami artworks. The day was opened by Sjoerd Verduyn Lunel, former chairman of PWN, followed by some nice lectures. One of the lectures was about the plastic number, a kind of generalisation of the golden ratio. It is always a fun day with lots of art which has its origins in mathematics.
Interesting announcement: next year, TU Eindhoven will host the annual Bridges Conference. The Bridges organisation aims to make connections between mathematics, art, music, architecture and culture. The conference will take place from 14 to 18 July, more information can be found here:
