This week we were treated to another oil spill that will cost millions to clean up and endanger many different species of marine wildlife. A pipe that was installed in 1987 burst close to Refugio State Beach in south Santa Barbara, spilling around 100,000 gallons of crude oil into the surrounding waters. California Governor Jerry Brown has since declared a state of emergency in Santa Barbara County and crews have set up blockades that are designed to contain two visible oil slicks.

Two-time Pulitzer Prize winning author and historian, David McCullough, is perhaps best known for his biographies of John Adams and Harry Truman. His most recent book, The Wright Brothers, is his third of a series on great accomplishments in technology (the other two portray the building of the Brooklyn Bridge and The Panama Canal).
