What are similar triangles and how can we tell if triangles are similar or if they are not? Students and faculty from CityLab High School, Dallas ISD join us on a beautiful day at Fair Park, an architectural treasure trove in the city of Dallas to explore this question using the sights of the Esplanade. Supplementary Activity Guides for this video to extend student learning for K-12 grade levels are freely available here:... CONTINUE READING
Fair Park, a state and National Historic Landmark, has the largest collection of 1930s Art Deco style architecture in the United States, located on 277 acres. In this video, we briefly discuss what art deco is and how it is related to STEM.... CONTINUE READING
Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, discusses some of the shapes within the Campanile Window installation at Dallas Love Field airport, and how they’re used to support and integrate the irregularly-shaped windows with the more classically rectangular shapes of the ticketing hall in which they've been hung. This video was supported by the City of Dallas Office of Cultural Affairs. Supplementary Activity Guides for this video to exten... CONTINUE READING
What is the basic unit used to create this mosaic? We use math to figure it out! We invite all interested groups to reach out and find more information on creating content of their own math walk or STEM walking tour with us at https://talkstem.org/create-your-own-walkstem.... CONTINUE READING
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
The television screens laid out in the Dallas Public Library Louise Kahn Pavilion are arranged in an array, a regular grid of objects. This can make calculating how many screens are in the are the array a quick process – join us as we discuss the techniques to do so!... CONTINUE READING
Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, admires the modern structure of a high rise building in the Arts District and highlights the fact that there are many different ways to look at a mathematical problem. These methods may include: decomposition of the larger area into smaller rectangular areas and finding the larger area and then subtracting the areas of each rectangular array. He illustrates these methods by observing the windows on... CONTINUE READING
DNA is the molecule used to store genetic information in living things. Despite the vast amount of information it stores, DNA is physically very small, curled and bunched up thousands of times – in fact, if DNA was fully stretched out, it would be incredibly long! We make calculations of just how long here. Join talkSTEM and UT Southwestern faculty and grad students as they explore the STEM concepts on their campus.... CONTINUE READING
The sculpture Undulating X is constructed from metal in the shape of a giant chromosome, a discrete spool of DNA within a cell. But if a chromosome were actually this size, rather than microscopic, how big would the person who it belongs to be? Math can help us figure that out. Join talkSTEM and UT Southwestern faculty and grad students as they explore the STEM concepts on their campus.... CONTINUE READING
There’s a pattern of overlapping circles in the ground pavement around the medical center – but is there any way to estimate how many circles there are? We investigate a few different methods of figuring it out! Join talkSTEM and UT Southwestern faculty and grad students as they explore the STEM concepts on their campus.... CONTINUE READING
