Beaten by Sudduth by nearly 10 seconds in 1988, Walker dominated a field of 29 starters who rowed against the clock on the Charles River...
...awarded half of the $470,000 prize for his contributions in pioneering a method of measuring the minute movements that occur inside atoms. Ramsey's so-called separated oscillatory fields technique did not just become a valuable scientific tool; it also provided the basis for modern-day atomic clocks. Like the ticking of a pendulum in a grandfather clock, the rapid-fire (9,192,631.770 times a second) oscillations of cesium-atom nuclei, spinning like tops inside a magnetic field, can be used to pace off time...
...wait until 11 o'clock that night before I was perfectly miserable, and only then did I think of my father and the times he would stay up with me when I was sick and make sure I felt well, or at least comforted...
...vandals apparently timed their attack perfectly, putting their plan into action one night before campus police began their around-the-clock guard of the statue...
...Ramsey's increased precision that enabled scientists to use the atomic clock for the official measurement of world time. In 1967, his method was used to redefine the second as the length of time it takes a cesium nucleus to rotate 9,192,631,770 times...
