How Can We Calculate Pi?

  • September 9

Pi is a number describing the ratios various parts and measurements of circles have with each other, meaning we can calculate it from any measurable circle – including this sculpture, Sun Disc Triptych by Jesús Moroles. Join talkSTEM and UT Southwestern faculty and grad students as they explore the STEM concepts on their campus.... CONTINUE READING

How do Scientists use Observations?

  • September 9

Science is a collaborative effort, bringing together observations from many different times, places, and observers. The many eyes on display in the UT Southwestern Medical Center echo this, something we discuss! Join talkSTEM and UT Southwestern faculty and graduate students as they explore the STEM concepts on their campus.... CONTINUE READING

How Does a Sundial Work?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor discusses the science behind sun dials, and how they work. You can create your own sun dial at home.... CONTINUE READING

What Is an Ellipse?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor explores the space and notices the recurring appearance of a relatively unusual shape in architecture, ellipses. In this video, this shape is explored and measured and different ellipses are compared.... CONTINUE READING

How do you use mathematical clues?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor shows how to look for mathematical clues in real world places in order to solve a problem or answer a question. In this case, the question is whether the building's column is actually straight or not.... CONTINUE READING

How does Gravity Affect Flowing Water?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor explores the natural phenomenon of water tapering in as it flows downward. Have you ever noticed this? A supplementary activity guide is available for this video, thanks to participation by faculty and students at Simmons School of Education and Human Development at SMU: https://talkstem.org/talkstem-activity-guid...

What is Mathematical about a Tree?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor wonders what is mathematical about trees. He asks why do trees always have a larger singular trunk at the Earth, and more smaller branches in the sky? Why not one singular branch that stretches up? Dr. Glen Whitney explores this natural phenomenon that applies to all trees. A supplementary activity guide is available for this video, thanks to participation by faculty and students at Simmons School of... CONTINUE READING

How do you Measure Slope?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor wonders what is the slope of the amphitheater and figures out a quick way to estimate it.... CONTINUE READING

How Do You Create Your Own Labyrinth?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor discusses the differences between a labyrinth and a maze and poses the math questions that directly relate to the design of a labyrinth, which is a winding path that never repeats, and yet has only one route that can take you from the outer edge to the center. How do you design a labyrinth? How many different labyrinths could there be or is this the only one?... CONTINUE READING
