(Chronological order: newest first; ongoing programme at the end.)

The year-by-year timeline below is built from Events pages tagged Outreach (including online talks and videos during the pandemic, e.g. Perfectoides in 5 minutes, The Shape of Data for SEP Prepa en línea, and the virtual CIMAT-Mérida Summer School 2020). Further down, a short editorial list covers festival organisation, media appearances, and items without a single dedicated page.

Timeline from site event pages

Activities with a page under Events and the Outreach tag (or Spanish/French equivalents). Includes online talks during the pandemic when the event page records that in the location or format. Each block below is headed by the calendar year; within a year, newest first.

  • 2023 (Jan.): 2nd SEP Science e-Fair (virtual); certificate on file — no dedicated event page yet (same Prepa en Línea SEP programme).

Mathemagic and p-adic magic cards

Outreach through mathemagic, the p-adic magic cards project, and related workshops (content in development). The p-adic magic cards are a playful tool combining card games with p-adic structures to bring non-Archimedean mathematics to a general audience.

Web applet (HTML): the materials include an interactive HTML applet — classic 27-card trick (base-3 arithmetic), for projector or tablet/phone: Open “Magic with 27 cards” (applet).

Essays (Substack)

Essays and reflections on Substack (@yoyontzin): mathematics, philosophy and narrative.
