Math Encounters:
"From Two Dimensions to Four: Exploring mathematics through pop-up constructions" featuring Richard Hammack,
Wednesday, December 3, 2025

We tend to think of pop-up books as a genre of children's literature, but lurking between the pages are interesting and complex mathematical mechanisms. By their very nature, pop-ups are a perfect (and largely unexplored) medium for describing and communicating mathematical form. Join mathematician, paper engineer, and designer Richard Hammack of Virginia Commonwealth University as he presents his pop-ups of mathematical objects and previews his Pop-Up Book of the Hypercube. Plus, participants will create their own 4D cube pop-up card to take home!

Special introduction by Annalisa Crannell, professor of mathematics at Franklin & Marshall College.

Math Encounters is MoMath’s popular free public presentation series celebrating the spectacular world of mathematics. This program is funded by Simons Foundation International and administered by the Simons Foundation’s Science, Society & Culture division.
