## Real Places Conference Exhibit Table Math in Texas History

We love having conversations about math and these were all about Texas history too!  The Texas History Center’s 8th annual Real Places Conference attracts museums of all kinds.  It was a great opportunity to share and showcase some of our land survey artifacts including a real Vara Chain, a 1/2 Gunter Chain, a document written by Robert Creuzbauer that explains

## Take and Make: T-Puzzles

The T-Puzzle is a very old puzzle and it comes in several versions.  In the version we made, the width and height are the same.   Jordan Varat cut a board with silhouettes  as puzzles that we will send to our math rooms in Austin, Mankato and Albuquerque.  Megan Do worked on the CAD files and created the printable silhouettes

## MathHappens @ Los Angeles Maker Faire

April 1st, 2023 We staffed a booth at Maker Faire Los Angeles.  We brought some of our favorite models, activities and giveaways and we were also able to bring the brand new Hat Tile or Mono Tile newly discovered by an amateur mathematician. Intern Ella Basken made the trip and did an outstanding  job representing with the team.  Read Ella’s

## Take and Make: Tusi couple for a UT Perspectives Class

The Tusi couple is a mathematical device in which a small circle rotates inside a larger circle twice the diameter of the smaller circle.  With this relationship of diameters, each point on the circumference of the smaller circle actually follows a linear path as the rotation occurs. Here’s a link to a video so you can see it in motion. Files to

## Take and Make: Shisima Game from Kenya for SE Branch Library

SE Branch library invited us to participate in their event celebrating music from Kenya.  We found a new strategy game two player strategy game called Shisima that is related to tic-tac-toe, that originates from Kenya.  Melissa Wilkinson cut and made the design that Stefany Espinoza created.  Quan Nguyen and Marianne Villanueva brought the game to SE Branch, participated in some drumming and

## Take and Make: Adjustable Hyperbola

Dan van der Vieren who uses our Parabola stretchers with his college Algebra classes wondered if we could design a frame to make a hyperbola like this one. As it happens, we had a couple of ideas.  The best result was this gear design.  You can string the frame with elastic cord with the plate in the top position and

## Take and Make: Tabletop Optical Illusions and Perspective Playground

We found an instructable on making chalk art patterns in CorelDraw.  But guess what? — you can use this technique to poster print all kinds of fun 3d designs.  The instructable is here.   Its pretty cool! We sent a logo perspective box, aReuleux car and some conic section models to the NWMath Conference. PDFs can be printed in various sizes.  “Chalk”

## MathHappens @ Austin Museum Day!

Here’s a link to an interview I did this morning with CBS Austin’s Trevor Scott.  MathHappens Foundation is an active participant in the Austin museum community.  We have learned a lot in eight years of collaborations about the way museums approach storytelling, sharing knowledge and ideas with an intent to spark interest and start conversations.
