New York Times: Steven Chu, the Nobel Prizewinning physicist who heads the US Department of Energy, has emerged as the White House’s lead representative in the efforts to halt the oil gushing into the Gulf of Mexico. As the New York Times‘s John Broder reports, Chu and other government officials have determined the nature and timing of several key interventions. Robert Dudley, BP’s lead representative in the containment efforts, says of Chu: “He can speak with senior executives and then with subsea engineers, and ask probing questions about pressure variants and burst steel casing. He can actually interpret the data and have a very sharp engineering discussion with an expert from BP.”
