Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have created an optical clock that's just 1 cubic centimeter—small enough to fit on a standard silicon chip—and can track time intervals with precision to 270 quintillionths of second. (One quintillionth is equivalent to 1 times 10 to the negative 18th power, or 0.000000000000000001.)
