Clocks : For Kids - Talking - Grand Father - List of Brands - Home
 
Who hasn't used a clock to tell time before? Clocks are an essential tool, that are commonly used in our daily lives. Just about every house contains a clock in one form or another.

Clocks can not only be useful to tell the time, they can also be beautiful. Grand Father clocks are especially large, ornate and extremely pretty pieces of furniture. They also make for a great gift.

Many clocks also come with chimes, or other sound effects, which can be fun for children. A ticking clock can be a soothing sound.

Clocks are also meant to be fun and many put a childrens clock in a kid's room. Some clocks are even shaped like animals or other creatures.

For hundreds of years we have used clocks. Clocks continue to be an intrical part of our lives.

Those who like to play the game of chess, routinely use a chess clock to keep track of the time of the match. Each player is routinely alotted a set period of time to finish the match. A special clock is used, that stops between turns.

Clock Making
Clock making is a lost art, at one time clocks had to be hand made, literally part by part. Today most clocks are built by machines and mass produced.

If you do have one of these fine clocks from yesteryear, perhaps one passed down over the generations. Be sure to appreciate and take care of it.

A person that makes and repairs broken clocks is called a "clockmaker". The clockmakers of old were master craftsmen who built clocks by hand. The work was long and tedious and had to be very precise.

Modern clockmakers rarely build clocks anymore, however they are still needed to repair antique clocks that were handmade.

Did you know that? While Horology means the study of time, it also means the art of making clocks and watches.

Online Clocks
If you are looking for the most accurate time, or the time say in different time zones then you may want to try these internet resources. These website offer online clocks which can tell you the time right now, anywhere in the world.

Have you ever had trouble waking up in the morning because your alarm clock just is not loud enough?

If you can sleep through this bad boy, then you are obviously staying out way too late and partying like Jim Morrison.

If you are tired of wimpy alarm clocks, see how to build this industrial strength version that is sure to wake you, maybe your neighbors too and possibly even wake the dead!!
 
What is an atomic clock?

A
tomic clocks are specialized clocks that use electronic transition frequency in the microwave optical, or ultraviolet region of the electromagnetic spectrum of atoms as a frequency standard for its timekeeping element. Atomic clocks are currently the most accurate form of keeping time. They are used in global navigation satellite systems such as GPS systems.

Where is the United States atomic clock located?

In the United States, the standard of time is regulated by the US Naval Observatory's Master Clock (USNO), the official source of time for the Department of Defense. The effects of these mechanisms are felt by all of us in the f­orm of alarm clocks, computers, answering machines and meeting schedules.

When was the atomic clock invented? and where?

In 1945, Columbia University physics professor Isidor Rabi suggested that a clock could be made from a technique he developed in the 1930s called atomic beam magnetic resonance. By 1949, the National Bureau of Standards (NBS, now the National Institute of Standards and Technology, NIST) announced the world’s first atomic clock using the ammonia molecule as the source of vibrations, and by 1952 it announced the first atomic clock using cesium atoms as the vibration source, NBS-1.

How many different types of atomic clocks are there?

There are 3 different types of atomic clocks, they all use different methods of keeping time.
  • Cesium atomic clocks employ a beam of cesium atoms. The clock separates cesium atoms of different energy levels by magnetic field.
  • Hydrogen atomic clocks maintain hydrogen atoms at the required energy level in a container with walls of a special material so that the atoms don't lose their higher energy state too quickly.
  • Rubidium atomic clocks, the simplest and most compact of all, use a glass cell of rubidium gas that changes its absorption of light at the optical rubidium frequency when the surrounding microwave frequency is just right.

Can I buy an atomic clock?

Atomic clocks can be purchased, yet they are extremely expensive. A company called Agilent Technologies sells one, but it costs more than $50,000.

There are less expensive versions that use time signals sent out by the US atomic clocks to tell the time. These clocks are quite accurate clocks. Lacrosse Technology Makes these type of Clocks, so does Meade.
 
If you have a website you may want to add a clock for various reasons. There are websites that are solely dedicated to this purpose. Many of these sites allow you to copy a simple script code and embed it on your own website. This small code will in essence power the clock. Here are a list of websites you can find these clocks, below each listing is a clock taken from that site.

Clock Tag
Here you can find clocks for your website or blog. Analog clocks, digital clocks and calendars for your website.
