>From Daniel Kleppner's Time Too Good to Be True Physics Today, March 2006 http://scitation.aip.org/journals/doc/PHTOAD-ft/vol_59/iss_3/10_1.shtml The accuracy of these clocks has improved by roughly a factor of 10 every decade since they were introduced in the mid-1950s and in the next few years the accuracy is expected to reach 1 part in 10E16. Exponential, just like Moore's law. -- These are my opinions.
