Be Entertained While Being Informed Of The Time Through An Automatic Clock Radio

By Jeremy Spainhusband


Today, time is measured through the use of clocks. On the other hand, radios are primarily used for entertainment purposes. Nonetheless, despite the differences in their usage, these items are considered among the important inventions that have significantly affected man's way of life. Today, with automatic clock radios, consumers can own both clocks and radios as one single device.

"Time is gold" as they always say. But how does one keep track of time? In the ancient civilizations, time has been thought of in very imprecise terms. Earlier civilizations then based time from the positions of the celestial bodies-such as the sun, the moon, the planets, and the stars. It is unknown when humans began using devices to measure time. Nonetheless, a vertical stick, gnomon, or obelisk that casts a shadow-more commonly known as sundial-is among the first devices believed to be used to measure time. This device, based from the sun, allowed the daylight to be divided into hours and has been widely used in Ancient Egypt around 1500 BC.

Along with the sundial, various researches also showed that ancient civilizations also used other devices to measure time. Included among these are oil lamps, sand glasses, clepsydras, and candle clocks. Most of these ancient clocks employed the seasonal method of measuring time. Today, clocks can be purchased in a multitude of types such as automatic clock radios. These clocks are mostly mechanical devices that employ the Sumerian Sexagesimal System which is based on the number 60 and has exactly 12 hours for day and 12 hours of night. This better system of measuring time was first introduced during the late 13th Century.

Clocks were invented a long time ago when radios were invented. The history of radios actually began with the discovery of radio waves that allowed data-such as music, speech, and pictures-to be transmitted over the air. It was during the 1860s when the existence of these waves was predicted by Scottish physicist James Clerk Maxwell. By 1895, Italian inventor Guglielmo Marconi proved the feasibility of radio communication after sending and receiving the first radio signal in Italy. Today, radios are being used to provide entertainment to kids and adults alike.

Though invented centuries apart, advancements in technology allowed clocks and radios to be incorporated in one single device. These devices are called automatic clock radios which actually are a type of alarm clocks that reminds one of time with music or news from the radio rather than harsh noise. These items are alarm clocks that feature radios that may be set to start playing at specified times. With the discovery of these items, users are given the chance to keep track of time, while being entertained, at the same time.

Clocks and radios are indeed great inventions that have a great impact on man's way of life. As such, the invention of automatic clock radios allowed man to be entertained with the functionalities of radios while at the same time keeping track of time with their clocks.
