This cup is a cherished artifact. When @jodi finally got to lecture at the Les Houches school on #DarkMatter in 2021, she brought back two of them for us. Since #LesHouches was the original source of inspiration for writing "The Dark Matter Discoverer's Guidebook", this cup (filled with espresso) accompanied me too many early morning #writing sessions for the book.
I think it is important for writers to have magical totems that support the process. :-)
