Cell phones could keep atomic time
Atomic clocks may be headed into cell phones, thanks to a breakthrough by federal researchers, according to News.com . "Scientists at the National Institute of Standards and Technology have demonstrated the heart of an atomic clock that's believed to be a hundredth the size of any other atomic clock, NIST said Monday. The clock's inner workings are about the size of a grain of rice, consume less than 75 thousandths of a watt, and are so stable that just one second every 300 years is gained or lost. |
