Although today’s best optical atomic clocks can be used to make extremely precise measurements, they are still limited by the noise from the spin statistics of the many atoms they interrogate, known ...

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 ...

A scheme of the clock comparison: The new indium-ytterbium crystal clock was compared with the strontium lattice clock, the ytterbium single-ion clock and the caesium fountain clock of PTB. Credit ...
