The Scientist’s Clock

Author: Clockers

atomic-clock-with-moon-phaseWhen you’re making precise measurements, recording evidence, and refining your hypothesis, you need an accurate timepiece.  Scientists and researchers around the world use atomic clocks to record time at the most accurate measurements.  In addition, space scientists and astronomers often use atomic clock moon phase capabilities to track activity in the skies.  It’s essential for all serious researchers to have an atomic clock; after all, as all scientists know, a matter of seconds can be the difference between a major discovery and another failed hypothesis. 

When setting up an atomic clock, it often takes the clock a few days to receive the atomic signal from one of the worldwide transmitters.  If you live in the United States, you’ll be receiving your signal from Colorado.  But once you have the signal, the atomic clock is accurate down to as little as a hundredth of a second (depending on the model).

Atomic Radio Clocks

The radio clock, often referenced as the atomic clock, is one of the most accurate clocks on the planet.   These clocks are referred to as atomic clocks because their time is based on radio waves intercepted from actual atomic clocks, and if synchronized correctly, are accurate to the second.  Once each day, (usually during the nighttime) a radio clock will attempt to receive a signal broadcast from an atomic clock, and adjust its time accordingly.  As atomic clocks are accurate down to miniscule fractions of a second, for casual use, the radio clock is much more accurate than most timepieces. 

There are several longwave radio transmitters around the world that broadcast an atomic clock signal, in the US, WWVB, a true atomic clock, is located in Fort Collins, Colorado and broadcasts a signal receivable throughout North America.

What is an Atomic Clock?

An atomic clock is a type of clock that uses an atomic resonance frequency standard as its timekeeping element. They are the most accurate time and frequency standards known, and are used as primary standards for international time distribution services, and to control the frequency of television broadcasts and GPS satellite signals.

Atomic clocks do not use radioactivity, but rather the precise microwave signal that electrons in atoms emit when they change energy levels. Early atomic clocks were masers with attached equipment. Today’s best atomic frequency standards (or clocks) are based on absorption spectroscopy of cold atoms in atomic fountains.
