The most accurate clock of all time: http://www.newscientist.com/article.ns?id=dn7397 Hidetoshi Katori and his colleagues at the University of Tokyo have built a clock based on strontium atoms trapped in an optical lattice. The resonance is at 429,228,004,229,952 Hz. Katori claims that this clock will keep time with an accuracy of 1 part in 10^18. -ch _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
