We had a great evening with the MoMath Family Friday Audience with well over 100 people!  Tessellating abounded. This display of Michelle Tat’s creative interpretations of the fifteen pentagons was very popular for photos after our talk!  Did you notice the #1 tiling for the 40x 70″ display?  We made a template you can laser cut and then trace. Our

## Advice from the MOXI Museum on Golden Ratio Exhibit

Comments from the  MOXI Museum in Santa Barbara.  They liked the Golden Ratio Calipers and decided to make their own and set up a self guided exhibit. They’ve got some great advice for any museum interested in doing this too. “I have in fact used your files in a crude way and brought out some ratio calipers in my museum’s

## Educator Night at The Thinkery

MathHappens Interns Josephine Sheng and Viyang Shah had the opportunity to try out an activity on Freese’s Dissections at The Thinkery’s Educator Night on October 17th, 2019. They had a great time interacting with educators in the Austin area and demonstrate to them how math can be approachable and fun. Some even said they’d leave their personalized puzzles at their

## A 119 Year Quest to Understand Tessellating, Convex, Irregular Pentagons

The idea for MathHappens to work with tessellating pentagons originated from intern Jason Gorst’s suggestions for future projects on his final report. A tessellation describes an arrangement of shapes that tiles a plane with no gaps or overlaps.The challenge of finding all possible tessellating pentagons was issued in 1900 by David Hilbert at the International Congress of Mathematicians in Paris

## MathHappens @ Austin Museum Day- You are Invited!

In this photo Ximena Mercado Garcia has items from each Museum Day math station on the table to share with Univision and their viewers. Las matemáticas también pueden ser divertidas. ¡Únete y descúbrelo tu mismo! Sarah Bacca is sending this note with all the details to teachers, principals and schools.  We hope everyone gets the word! Dear Math Enthusiasts,

## Great time presenting the 15 Tessellating Pentagons to the UT Math Circle

No paper, no pencils, just working with the shapes.  We had a ball!  Thank you for inviting us and providing a great meal Dr. Jennifer Austin!  Teachers got to take home a set of about 15 of their favorite type.  Finding the types began in 1900 with Hilbert’s challenge and ended in 2017.  Its a great story.

## Take and Make: Mathematical Origami

I want the files now! We attended the MOVES Conference at the Museum of Mathematics in New York this summer.  Main topic?  Mathematical Origami.  There is a lot going on with capabilities to weaken materials and facilitate folding with lasers and other precision devices.  Robert Lang and Eric Demaine are both experts and innovators in this area and they spoke
