What is Symmetry Doing for Us?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor admires the dome shaped ceiling in Dallas Hall. He notices the symmetries in the design of the rotunda and finds a linear relationship between symmetry and decorative items. This is a great example of a beautiful design produced through the use of a variety of different kinds of symmetries. A supplementary activity guide is available for this video, thanks to participation by faculty and students at... CONTINUE READING

How did Calatrava Build this Sculpture?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor admires the stunning and dynamic Wave sculpture created by renowned artist Santiago Calatrava. He asks and answers three questions about this artwork: Is it straight or is it curved? Is it symmetric? How did Calatrava build this sculpture?... CONTINUE READING

How Symmetrical Is It?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor discusses different kinds of symmetry you can experience in this place including rotational and mirror symmetry.... CONTINUE READING

What is Symmetry?

  • September 9

Symmetry describes the properties possessed by some shapes and objects that allows them to look similar when flipped, turned, or shifted. We take a look around the Dallas Public Library to find instances of symmetry in the designs around us.... CONTINUE READING

How Do We Measure Slope?

  • September 9

Slope is a way of describing the way that a line or plane – like a sidewalk – changes over a distance. Using these principles, we describe the way the grounds around us were built. Join talkSTEM and UT Southwestern faculty and grad students as they explore the STEM concepts on their campus.... CONTINUE READING

What’s My Question – Estimation, Quantity, and Scale

  • September 9

Estimation, quantity, and scale help us understand aspects of the world around us that we can’t always interact with directly – these tools help us understand large objects and numbers, and ways to represent them. We discuss the questions students at the St. Philip’s School and Community Center posed within this math theme to show just how intuitive this can be! This material is based upon work supported by the National Science Foundation under Grant DRL 2115393. Any opinions, findings, an... CONTINUE READING

What is the Slope of this Staircase?

  • September 9

We explore how to use slope, the ratio of height to horizontal distance, to better understand how stairs are designed based on international building codes to keep us safe. Supplementary Activity Guides for this video to extend student learning for K-12 grade levels are freely available here: https://talkstem.org/talkstem-activity-guides/ We invite all interested groups to reach out and find more informat...
