Philadelphia gets 17 free math events tied to global congress

Philadelphia will host 17 free public math events July 24-28 alongside the 2026 International Congress of Mathematicians, bringing talks, films, performances and hands-on activities downtown. The lineup is designed to show how mathematics shapes art, music, science, culture and technology for families, students and the math-curious.

Why it matters: - The events open the world’s top math conference to the public and make advanced mathematics more accessible outside academia. - Philadelphia residents and visitors can attend free programming that connects math to daily life, culture and technology. - The schedule gives families, students and other nonexperts a way to engage with mathematicians during a major international gathering.

What happened: - The 2026 International Congress of Mathematicians will offer 17 free public events in downtown Philadelphia from July 24-28. - Events will be held at the Pennsylvania Convention Center. - All events are free, though some require advance registration. - Additional information is available on the ICM 2026 website.

The details: - The Math Festival runs Friday, July 24, from 2-6 p.m. and Saturday, July 25, from 2-6 p.m. - The festival will include hands-on activities, talks, games and art for all ages. - Public lectures feature Terence Tao on “Mathematics in the Age of AI” on Friday, July 24, from 7:15-8:15 p.m. - Talithia Williams will present “Between Numbers and People: The Art of Mathematical Communication” on Saturday, July 25, from 5:30-6:30 p.m. - Geordie Williamson will give “AI and Humanity’s Long Conversation” on Sunday, July 26, from 3:30-4:30 p.m. - Manjul Bhargava will present “Magic Squares, Cubes, and Hybercubes from Ancient Origins to Recent Advances” on Monday, July 27, from 3:30-4:30 p.m. - Ingrid Daubechies will present “Mathemalchemy: A Mathematical and Artistic Adventure” on Tuesday, July 28, from 3:30-4:30 p.m. - The Mathematics and Art track includes “Math, Music and the Mind” with Daniel Forger on Friday, July 24, from 4:30-6:30 p.m., followed by an organ performance at Cathedral Basilica. - “Mathdramatics: Math on Stage” with Emma LaPlace runs Saturday, July 25, from 5-6 p.m. - “From Classroom to Canvas: Creating the ICM Mural With Oluwafemi” takes place Sunday, July 26, from 4-5 p.m. and focuses on a mural created for the congress with Mural Arts’ Art Education program. - The American Mathematical Society will present “The Music of Mathematics” on Tuesday, July 28, from 7-8:30 p.m. - Documentary screenings include the two-part “Journeys of Black Mathematicians” on Friday, July 24, from 2-3:45 p.m. and Saturday, July 25, from 11 a.m.-12:45 p.m. - Each screening of “Journeys of Black Mathematicians” will be followed by a Q&A and can be viewed separately. - “Felix Klein — Insights From the Outside” screens Sunday, July 26, from 5-6:30 p.m., followed by a Q&A. - “PHENOMENA” screens Sunday, July 26, from 7:30-10 p.m. - Special events include “The Proof in the Code: A Conversation with Kevin Hartnett and Thomas Lin” on Saturday, July 25, from 1:15-2:15 p.m. - Hartnett’s book explores Lean, a programming language and proof assistant described as a truth machine that guarantees a proof is 100% correct. - “The Joy of Why” live podcast recording with Steven Strogatz and Janna Levin is set for Sunday, July 26, from 2-4 p.m.

Between the lines: - The programming mixes academic talks with art, film and live performance to broaden the audience beyond professional mathematicians. - The emphasis on AI, communication, music and visual art suggests a push to show math as both practical and cultural. - The public-facing schedule also helps position the congress as a citywide event rather than a closed scholarly meeting. - The congress is supported by the American Mathematical Society and the Simons Foundation. - The 2026 congress runs July 23-30 and marks the first ICM in the United States since 1986.

What's next: - Attendees will need to register in advance for some events. - The congress will continue with invited talks, panels and presentations through July 30. - Organizers are using the public schedule to build local engagement around the larger conference.

The bottom line: - Philadelphia is turning the 2026 ICM into a weeklong public math festival, with free events aimed at making the field feel more accessible, creative and relevant.
