Years of comparisons among the world's best atomic clocks -- based on different atoms -- have established the most precise limits ever achieved in the laboratory for detecting possible changes in ...

In the future, optical fibers could connect all optical atomic clocks within Europe -- a milestone for various users of optical frequencies in research and industry. In the future, optical fibers ...

OK, just imagine. We magically got a good old 80486 DX 50 Mhz in a 0,13 micron process, and we manage to OC it to 1 Ghz (unlikely, I know...).<P>How it will compare to a P3 or Athlon at the same clock ...

This press release is available in German. Optical atomic clocks measure time with unprecedented accuracy. However, it is the ability to compare clocks with one another that makes them applicable for ...

Years of comparisons among the world's best atomic clocks—based on different atoms—have established the most precise limits ever achieved in the laboratory for detecting possible changes in so-called ...
