MIT announcement. And Paul Krugman, on "a truly great man."

His speeches and his voluminous writing had a lucidity and bite not usually found in academic technicians. He tried to give his economic pronouncements a “snap at the end,” he said, “like Mark Twain.” When women began complaining about career and salary inequities, for example, he said in their defense, “Women are men without money.”
