modeling upside down
If you want to form a parabola, you can chart the points using a mathematical formula, or you can take a piece of string and hang it from two points. The result will be the same, though one technique will be easier and more direct and useful than the other. The photos at left and below were sent to me by Frank Wilson, author of The Hand: How Its Use Shapes the Brain, Language, and Human Culture from his trip to Barcelona. Gaudi's Sagreda Familia was modeled upside down as shown below using string to prove the concept before construction. What is it about the hands that some people just don't get? You can take any subject from mathematics to literature and increase its hold on the attention of young students by making it hands-on. Another view of Sagreda Familia more closely resembling Gaudi's upside down model is shown below.
