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.

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 Flying Pancake is a fun name for a unique airplane that is no longer in use. We wonder as to why this aircraft was designed to have a flat wing-like body giving it such a large surface area? We explore this unique design and come to understand how this design met its goals but also came at a cost. Supplementary Activity Guides to extend student learning at the Frontiers of Flight Museum for K-12 grade levels are freely available here:... CONTINUE READING
The Command Module of the Apollo VII mission has a truncated cone shape which was essential to its goals of leaving the earth's atmosphere and then safely re-entering the atmosphere to bring its crew back to Earth in 1968. Here, we wonder how the shape of the module was an important aspect of its design and learn about cone shapes, air resistance, and surface area. Supplementary Activity Guides to extend student learning at the Frontiers of Flight Museum for K-12 grade levels are freely availabl... CONTINUE READING
We notice that the bottom surface of the Command Module of the Apollo VII space mission looks different from the material making up the rest of the module. We learn that this difference is a critical part of the design of the module that brought home the crew of 3 astronauts in 1968. Further, the heat shield material that was developed for the command module’s bottom surface is now something we use in everyday life – great example of innovation that ends up being used far more widely than an...
