@dailyshoot: 2010/05/19: Make a photo today that distills some simplicity from the complexity of the world. #ds185 It's powerful to still know how to use cross multiplication (here calculating dimensions for a video conversion). Thanks to my math teachers at Bedford Elementary School, Sudbrook Middle School, and Milford Mill High for showing me the power of math... even wacky Blooma Friedman, my 10th grade chemistry teacher, who insisted we learn how to use a slide rule (sorry Blooma, I did forget that).
