Things that are further away appear smaller to the eye, an effect which can cause parallel lines to look as though they converge. Using the bookshelves as an example, we investigate why this is the case.... CONTINUE READING
Library bookshelves are filled with fantastic books – but is there any quick and easy way to estimate how many are in a given area? Join us as we discuss our solution!... 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
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
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
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
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
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
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
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...
