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
The castle shelves in the Dallas Public Library are made up of a number of different basic shapes. Using our walkSTEM guide, we see just how many we can find! You can download and print your own shapefinder onto an acetate using this pdf: https://drive.google.com/file/d/1vBKbHnWZug5uBlM61LXAAEgU9dNaUwdY/view?usp=sharing... CONTINUE READING
This building has a unique design element – there is a gap in the facade of the building. Why would there be one? In this video, which is geared for high school students and older, Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, discusses temperature changes that we are used to, here in Dallas. He goes on to explore the mathematical relationship between change in temperature and the expansion factor of aluminum. Supplementary Activity Guides fo... CONTINUE READING
