The National Museum of Mathematics (MoMath) invites your family to a series of free public presentations celebrating the spectacular world of mathematics. This month's presentation is “The Structure of Space: Measuring the Shape of the Universe” with David Spergel.
This is a live-streamed event. Occasional video recordings are made available for a fee at videos.momath.org. There are two sessions occurring on this day, one at 3 pm CDT and another one at 6 pm CDT.
For more details and registration, please see here. For a list of their current events, check out their calendar. If you find yourself in New York City this summer, they could be worth a visit with your children.
