Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, has fun with a really big number by estimating the number of stones that were used to build the sidewalk on Flora street. Using number arrays, estimation, and collaborative groupwork, Dr Whitney and friends come up with their estimate and then visualize how tall of a tower these stones would be if they were to be stacked up vertically. Can you guess? Supplementary Activity Guides for this video to e... CONTINUE READING
Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, observes the grid of louvers up high at the AT&T Performing Arts Center and wonders: how do the louvers act as a sunscreen? How does Dallas’s latitude affect the design of the louvers? At what angle would you have the solar panels positioned in relation to the sun’s rays, if you were designing a building?

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
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
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
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
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
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
