From Hilbert to DNA: Space-filling curves on aperiodic tilings

Wednesday, September 9
4:00 pm and 7:00 pm
In person at MoMath

In 1891, David Hilbert showed that a simple recursive process could produce a space-filling curve — but only on a perfectly periodic grid. What happens when periodicity is removed?

Using the recently discovered Einstein hat tiling, new kinds of space-filling curves can be constructed — including one that appears to model the folding of the human genome better than any previously known mathematical curve.

Special introduction by Alex Kontorovich, Distinguished Professor of Mathematics at Rutgers University.

Can a curved surface be created entirely from straight lines?

Join MoMath online on Friday, August 28, at 12:00 pm ET, for Hyperboloids: Straight Lines with a Twist, featuring Sabetta Matsumoto, Tim Reinhardt, Jürgen Richter-Gebert, and Henry Segerman.

Four exceptionally imaginative mathematicians, artists, and makers will explore the surprising geometry of the hyperboloid of one sheet through ingenious moving models — from constructions made with rubber bands and wooden skewers to sophisticated 3D-printed designs and even a spectacular 130-foot-tall hyperboloid sculpture in Munich.

The free program will include the premiere of their new video followed by a live discussion with all four creators.

🎲 A night of mathematical fun awaits at MoMath!

Join award-winning educator Nat Banting for Family Fridays: “Dice Auction” on Friday, August 21, from 6:30 pm to 8:00 pm.

Can you predict what the dice will do? How much are you willing to bet on “maybe”? Play it safe, take a chance, and discover the surprising mathematics of probability in this fast-paced activity for the whole family.

Thanks to the generous support of Two Sigma, Family Fridays is free to attend.

Join Folding Fridays tomorrow, August 14, from 4:30 pm to 5:30 pm ET, and explore the Transformation Unit, created by origami artist Toshiaki Hojo.

Start by folding a hexagonal unit, then discover how these ingenious pieces come together: six Transformation Units can form a tetrahedron, while 24 can be assembled into a cube with one clever change in the folding pattern.

Explore geometry with your own two hands — there’s math in every fold!

Folding Fridays is online and appropriate for adults and children ages seven and up. Prior origami experience is required.
