Traders used to all buy and sell stocks in the same crowded room. Everyone received information at the same time, and the first guy to shout or signal got the sale. Today, using algorithms that exploit slightly different prices changing at slightly different speeds, and computers connected to exclusive fiber-optic lines that can buy and sell stocks within fractions of a second, high-frequency traders are able to buy low and sell slightly higher in virtually the same instant.
Charles Lindbergh may have shown human fortitude by flying across the Atlantic in his "Spirit of St. Louis," but now he has robotic company when it comes to transatlantic records. An underwater robotic glider built by Rutgers University students and scientists has achieved the first underwater robot crossing, after traveling beneath the waves for 221 days.
