Source sentences:
text: Since 2004, more accurate atomic clocks first cool the atoms to near absolute zero temperature by slowing them with lasers and probing them in atomic fountains in a microwave-filled cavity.
text: Since it’s easier to measure slower moving targets, and atoms move slower at lower temperatures, the most accurate atomic clocks cool the atoms to the point of almost absolute zero.
