The world's best clock, NIST-F1, has been improved over the past few years and now measures time and frequency more than twice as accurately as it did in 1999 when first used as a national standard, ...

The National Institute of Standards and Technology building in Boulder, Colorado, houses lasers and quantum physics that unlock far more than the passage of time. NIST shares the building with the ...

The U.S. Department of Commerce's National Institute of Standards and Technology (NIST) has officially launched a new atomic clock, called NIST-F2, to serve as a new U.S. civilian time and frequency ...

The National Institute of Standards and Technology (NIST) has announced that a new experimental atomic clock based on a single mercury atom is now at least five times more precise than NIST-F1, the ...

With a new and improved atomic clock, the standard of time in America is about to change -- a teeny, tiny bit. For the first time in 15 years, the National Institute of Standards and Technology, or ...

National Institute of Standards and Technology has officially launched a new atomic clock, called NIST-F2, to serve as a new US civilian time and frequency standard, along with the current NIST-F1 ...

An experimental atomic clock based on ytterbium atoms is about four times more accurate than it was several years ago, giving it a precision comparable to that of the NIST-F1 cesium fountain clock, ...

Physicists at the National Institute of Standards and Technology (NIST) have built an enhanced version of an experimental atomic clock based on a single aluminum atom that would neither gain nor lose ...

The world's best clock, NIST-F1, has been improved over the past few years and now measures time and frequency more than twice as accurately as it did in 1999 when first used as a national standard, ...
