On Monday, September 15, I am co-organizing a conference to discuss facts.

Discuss *facts*?

Yes, facts can be debated these days, both in Science and outside of it. More information at www.knaw.nl/en/events/de....

It was another wonderful edition of the *Summer School in Market Microstructure*. I always enjoy teaching this course with Thierry Foucault.

Next year, we will be at KU Leuven in Belgium. Consider putting your email on the email alert list on the course website (microstructure-course.com).

Vandaag in de Telegraaf. Pas op voor finfluencers die één bepaald aandeel, of een nieuwe crypto product aanprijzen. Blijf zelf nadenken. Als je je beseft dat je het eigenlijk niet weet, investeer dan liever in een mandje van aandelen.

Mijn eerste TikTok/Instagram video. Nu aandelen kopen? Dank Marlies de Baare van NTR voor je interesse in mijn advies.

Terrific! Congratulations, Yasmine, great group, great new campus, and nice country. Good luck.

Thanks a lot, Nate, I really appreciate your post. A lot of work has gone into it, with so many people collaborating. It is then really, really nice to get noticed by some whose work I admire and who inspired a lot of what we did. Thanks again.

I have to applaud @albertjmenkveld.com for exploring diverse ways of communicating science, including comedy. nonstandarderrors.com/comedy.html. And of course for his large scale (largest so far) many analysts study. #metascience #openscience #sciencecommunication 🧪
