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.
