How many students fit in the chapel while observing social distancing regulations?

  • September 9

Students from St. Philip's School & Community Center on a math walk stop at the school chapel. They wonder what the maximum number of people is that could fit in this space given social distancing protocols during the Covid pandemic? They use the patterns on the carpet, and some simple estimation strategies to answer their question. This material is based upon work supported by the National Science Foundation under Grant DRL 2115393. Any opinions, findings, and conclusions or recommendations... 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!

Does it ever seem like you parked at a store that is farthest away from the store you want? Join Dr. Glen Whitney, Founder of the National Museum of Mathematics, as you discover how to determine what the farthest points are within NorthPark Center.

How Hard Do Robots Work?

  • September 9

Much of the luggage sorting and transport at the Dallas Love Field Airport is manage by robots built by the Daifuku company. This system can process massive amounts of luggage every year – but how much does it handle, on average, every day? With some simple calculations, we can calculate just how fast this robot-run system operates compared to a human-only method.

How Can We Estimate the Amount of Water on Earth?

  • September 9

The terrazzo World Map in the main lobby provides a fairly accurate representation of the Earth’s surface. Using the lines separating its sections to divide it into quadrants, we can use fractions to estimate the portion of the whole covered by water. Combining these parts back together and comparing it to established numbers should give us and idea of how close we were able to get with our estimation!

How do Forces Work?

  • September 9

The sculpture Sky uses a structural system of fiberglass rods to keep all of its components supported and in place. The arrangement of these rods make use of tension and compression forces to spread out weight and and force along the entire structure – something that we can analyze through basic shapes.

What’s the Scale?

  • September 9

The giant mosaic North Texas Sunrise depicts many native texan flowers, all far larger than life. Using a standard 8.5" x 11" sheet paper as a measuring device, we calculate how much larger the mosaic flowers are than the real thing, determining the scale of the artwork.

What’s the Mathematical Pattern?

  • September 9

The floor tiles used to make Untitled (Love Field) by Lane Banks only come in four colors, but never allow two rings of the same color to touch. With that in mind, methods of calculating how many permutations – specific, ordered arrangements – of these segments are possible are discussed. This uses the mathematical concept of factorials to practice combinatorics – the study of combinations and permutations. This video was supported by the City of Dallas Office of Cultural Affairs.

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!...
