What Mathematical Differences Do We See?

  • September 9

The four individual works that make up Campanile Window have a similar-looking structure to each other, but are not identical. Methods of quantifying some of their differences mathematically are discussed, analyzing color, lines, and interior shapes. This video was supported by the City of Dallas Office of Cultural Affairs.

How Do You Measure Pitch and How is it Helpful?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, notices the two systems of ramps that lead into the Wyly Theater Center at the AT&T Performing Arts Center. He takes some quick measurements to figure out the slope, gradient or pitch of each of the two ramps, and then discusses how mathematics keeps us safe.

How tall is the Ad Astra sculpture?

  • September 9

Join Dr. Glen Whitney, founder of the National Museum of Mathematics on a math walk. He uses the power of similar triangles to calculate the height of a giant sculpture inside the NorthPark Center. How can we estimate the height of the sculpture without getting a ladder? This video was supported by NorthPark Center.

What is the angle at the very top of the Ad Astra sculpture?

  • September 9

Join Dr. Glen Whitney, founder of the National Museum of Mathematics on a math walk. With the help of friends, he attempts to estimate the angle at the top of this very tall angle at the top of the Ad Astra sculpture. This video was supported by NorthPark Center.

What are Color Equations?

  • September 9

Join Dr. Glen Whitney, Founder of the National Museum of Mathematics, on a math walk. As you walk throughout NorthPark Center, you may notice a pattern of artwork that reoccurs. There are several panels that appear like addition equations with color. Can you add colors like numbers? Dr.Glen Whitney explores the concept of adding colors using a color wheel. On a color wheel, you can calculate the angle bisector of two colors to find the resulting color if the two were mixed. We discuss how there... CONTINUE READING

How High Does it Climb?

  • September 9

The sculpture Venture, by Alexander Liberman, is composed of several steel tubes, stacked toward the sky. At such a great height, measuring its size by hand can be a challenge; instead visual estimation must be used. Additionally, the shapes comprising Venture are discussed, involving various ellipses and special forms that can even be recreated at home!

How tall is the sculpture?

  • September 9

A high school student at Hockaday School created a campus STEM walk for elementary students to enjoy. In this walk stop, she stops at a tall sculpture that contains glass shapes created by Hockaday students and invites us to estimate the height of the sculpture and also to estimate the total number of glass shapes on the sculpture using some math detective work!...
