On September 18, 2011, Dow put up a 46 foot tall chalkboard on the corner of Broome and Crosby in NYC with a very long math problem on it. Over the next few days, aided by the giant chalkboard’s website and Twitter account, people around the world came together to solve the problem.
Think about how remarkable that is. Someone put up a billboard, a tumblr website, and a twitter account and, over the course of five days, was able to get people from 94 countries to work together to solve a problem. This is why, while not being 100% sold on everything Dow does, I am a big fan of their thought that solutionism is the new optimism.
