Atomic Clocks Atomic clocks are among the first ways that people had to tell time other than by watching the location of the sun in the sky. It involves a type of frequency that has a counter on it. They are amazingly accurate at keeping time and lose it less often than the average digital clock does. Introduced in 1949, many homes still feature an atomic clock. They are a symbol of history as well as a great way to always know what the real time is. The original model of an atomic clock was modified in 2004. This is when technology kicked it up a notch. A small microchip was added so that the overall design of the atomic clock could be much smaller. Still, they operate by the use of frequencies send to the clock. You may not realize that the concept of an atomic clock is what is behind the design of GPS systems. As the research continues, the designs of atomic clocks continue to evolve. They have become much smaller than they once were. This is because they no longer require all of the inside workings they once did to operate. They are still just as effective for keeping time though as they ever were. Yet inside of the updated versions of atomic clocks is more technology than one might think. They have to be programmed with the right frequencies to collect all of the information. They have to be able to isolate the atoms and ions in order for the time to be recorded accurately. Keep all of this in mind when you decide if an atomic clock is too much of an investment for you. You can buy new atomic clocks for about $75. They come in many designs and models so you can display one wherever you like. On the mantel of a fireplace is a very common location for them. You can also buy historic atomic clocks that still work. Since these are deemed as collector’s items, they can cost several hundreds of dollars. It isn’t uncommon for an atomic clock to be something passed down from one generation to the next as an heirloom either.
