A few days ago, a small multicolored tit (*mésange*, in French) landed right in front of the door of the tiny house in which I was doing some construction. To remind me to send the last episode of the Mésange series?
Mésange is a newsletter series of 26 letters, that I am writing from Oct 2022 to Mar 2023. Each letter is a short story of 5-10 min read, telling one of my — hopefully *elegant* — experiments.
