Who among you has not been asked, “What is geography?” Who hasn’t struggled to find a simple, understandable definition? Can the answer possibly lie beneath the streets of Washington, DC? I happened to be working there when Dan Brown’s Lost Symbol came out, suggesting that the Secrets of the Ages are hidden below. As I commuted to work one morning, lo and behold, a huge banner on the floor of Metro Center boldly proclaimed, “Geography = Unique Coffee Flavor.” There you have it, folks, geography defined with such mathematical precision that you can almost taste it. Thanks to Starbucks, every Metro rider in our Nation’s Capital now knows the answer to the age old question that still stumps Harvard.
