How does the artist represent infinity?

• September 9

This video is part 3 of 3 videos visiting the artwork, This Land is Your Land in NorthPark Center. What is infinity? How did the artists create infinity for the viewer? Join Dr. Glen Whitney, Founder of the National Museum of Mathematics, as you discover how the artist created the sense of infinity in the piece, This Land Is Your Land, in NorthPark Center. Can you see other examples of infinity around you? This video was supported by NorthPark Center. Supplementary Activity Guides for this video... 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 Many Cells Does It Take to Cross the Road?

• September 9

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

How Did the Artist Create this Illusion?

• September 9

Room in the Mind by Patrick Hughes is a work of art depicting library shelves that seem to move and shift as you walk around the piece. This makes uses of motion parallax and forced perspectives to create the illusion of depth - something we discuss here. Join talkSTEM and UT Southwestern faculty and grad students as they explore the STEM concepts on their campus.... CONTINUE READING

How Tall is this Imaginary Person?

• September 9

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

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 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

How Many Circles Make Up this Pattern?

• September 9

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

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

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
