Another Chinese physicist at Columbia, Associate Professor Chien-Shiung Wu, went to Washington. Working with a topflight team at the National Bureau of Standards, she arranged an elaborate deepfreeze apparatus to cool radioactive cobalt 60 to 0.01° above absolute zero ( - 273.1° C.). The cobalt nuclei are known to be spinning, and they continue to spin in the deepfreeze, but their random "thermal" motions are reduced almost to nothing by the extreme cold. This accomplished. Dr. Wu and her helpers applied a powerful magnetic field that pointed the cobalt nuclei in one direction as if they were tiny magnets...
