Family Fridays at MoMath
Presented by Two Sigma

Next Up

“Dazzling Diffraction Patterns”

featuring Sarah Goodman

Friday, May 31
6:30 pm to 8:00 pm

(in person)

What do you do when something is too small to see with the naked eye?  Too small to see with a magnifying glass, or even a microscope?  How do we know what the structure of matter looks like at the tiniest length scales — how atoms arrange themselves in crystals, or what biological molecules look like?  Join Sarah Goodman, Teaching Assistant Professor at Stevens Institute of Technology, to explore how diffraction is used to reveal hidden structures in nature and in everyday objects.  We will use laser pointers to create our own dazzling diffraction patterns as we make our way towards understanding how we can use a diffraction pattern to uncover nature’s smallest secrets.

Family Fridays is designed to bring family members of all ages together to enjoy a diverse array of engaging mathematical activities, promoting interest and enthusiasm among kids and adults alike.

Thanks to the generous support of Two Sigma, this program is free to attendees.

MoMath is delighted to announce that Sarah Goodman, who is leading the May Family Fridays presentation, is a Fellow in the Museum’s Mathematics Outreach Seminar and Training (MOST) program, which prepares early-career female mathematicians to engage general audiences in their research and encourages them to conduct math outreach in their own communities.  The MOST program is presented with the generous support of the Simons Foundation, Dexter Senft, Anthony and Miraldina Meyer, Jean Taylor, Marjorie Winkler and Paul Hohenschuh, Richard Lethin, and Qualcomm.  To learn more and apply for the 2024 MOST program, visit


Here’s what participants have to say:

“I was very impressed at how such a program could be presented that truly worked for all ages!  I, at 68, was as fascinated as the kids.  It was fun watching them grabbing what they could and happily keeping up with the activities.”

“Super excellent for all ages — one of best programs ever (not just Family Fridays — all programs everywhere!)”

“Wow!  It’s the first time we are attending Family Friday series.  We are so impressed!  You guys are amazing!  Thank you!”
