Evolution of the Clock

“Necessity is the Mom of Invention”, or so the saying goes. Lots of of years in the past it turned crucial for humanity to arrange their time right into a chronological orderly system. Way back to the eighth century Hesiod wrote about celestial our bodies together with the rising of crops. Crops should be harvested when sure stars had been rising and the fields needs to be plowed when the celebrities go down.

Even as we speak some farmers nonetheless consider that crops needs to be planted in line with the wax and the wane of the moon.

Initially the primary manner for folks to inform the time was by watching the solar because it moved throughout the sky. They noticed that when the shadows had been shortest and the solar was instantly overhead, it was the center of the day, and when the solar was rising or setting near the horizon it was the start or the top of the day. This was not a precise science.


Sundials are the oldest units used for measuring time. Because the solar strikes from East to West, the shadow of the pointer strikes across the dial. When utilizing the sundial to inform the time one seems to be to the quantity the place the shadow of the sundial is pointing. The disadvantage with a sundial is that one can solely inform the time when the solar is shining, so whether it is night time time, cloudy or raining then one should use different measures.

Final yr I visited the picturesque village of Hawkshead within the Lake District the place the well-known poet William Wordsworth attended faculty. Over the doorway door into the varsity is a lovely sundial. I had by no means seen a sundial earlier than that was vertical and never horizontal.

Water Clock

A clepsidra (water thief) or water clock was invented by the Egyptians round 1400 B.C. Time was measured by water escaping from a vessel. Two containers had been used and one container was positioned increased than the opposite. Water from the upper container traveled right down to the small container by way of a tube. Marks had been positioned on the containers, and the extent of the water the place the marks had been positioned on the containers advised the time.

Many enhancements had been made to the water clocks through the years. The Greeks used them and added floats and gears connected to a stick which turned a wheel because the water rose.

The 12 months Divided into Months and Days

It was the Greeks who labored on a system taken from the traditional Babylonians and Egyptians. They devised that it took the Earth a yr to journey across the solar, and a circle has 36o levels. A yr has 365 days so the unique calender had twelve months of 30 days every with 5 days left over on the finish of the yr. It was additionally famous that it takes about thirty days to maneuver from one zodiac signal to the following, therefore the 30 day months.

Dividing the Day into Hours and Seconds.

Babylonians and Greeks divided the day into 12 hours every of sunshine and darkish in that the hours from Dawn to Sundown was 12 hours and from Sundown to Dawn was 12 hours. This was primarily based on the equinox days. Sadly the hours are totally different on daily basis which meant the water clock needed to be adjusted every day to account for the distinction it occasions between mild and darkish every 24 hours. Hipparchus found out the 24 hour cycle round between 147 to 127 B.C. however most individuals nonetheless used the seasonal hours for a lot of centuries. Nobody is aware of who lastly found out that it was a lot simpler to mix the 2 12 hours to make a 24 hour day. We nonetheless use the 12 hour time typically, whereas the Army and Medical Facilities use the 24 hour clock.

Hipparchus together with different Greek astronomers used methods devised by astronomers that had been developed by Babylonians who dwelt in Mesopotamia. The astronomical calculations used the Sumerial sexagesimal system which was a base of 60. It’s not identified why the quantity 60 was used, however it’s the smallest quantity that is ready to be divided by the primary six counting numbers, and additionally it is divisible by the numbers 10, 12, 15, 20 and 25. This makes it handy for figuring out fractions of the hour.

The Pendulum Clock

A few years handed earlier than Peter Henlein in Germany constructed a spring loaded Clock round 1510, and this invention was not very exact. One other sixty plus years handed earlier than a Clock with a minute hand was invented by Jost Burgi and this additionally didn’t work very properly. Then in 1656 Christian Hugyens made a Pendulum Clock that labored very properly, however it could be one other few years earlier than the minute hand was added to the clock.

The Pendulums within the first clocks had a mighty swing of round 50 levels, and because the clocks developed the swing lessened to about 10 to 15 levels. By 1840 the clocks had been working with exterior batteries and by 1940 the batteries had been contained in the clock.

Quarts Crystal Clocks

Quartz Crystal is a rock that appears like glass, and it’s the second most plentiful within the earth’s crust. An digital oscillator is used and controlled by the quartz crystal to maintain time. The sign is created by the crystal oscillator with very exact frequency, and these clocks are discovered to be extra correct than the mechanical clocks. Since 1970 the quartz crystal clock have been the preferred clocks utilized in timekeeping know-how.

Fashionable Day Clocks.

Now we have now Digital Clocks, and the favored Clocks are Projection Clocks the place one doesn’t have to lift or flip his head to see the time. One has solely to have a look at the ceiling or the wall the place the sunshine and time of the clock is projected. We now have Atomic Clocks which hold essentially the most correct time with using Radio Alerts from the NASA clock. Many clocks should not have to be reset when one travels or when the time is modified for Daylight Financial savings Time. No extra excuses in regards to the clock being flawed when one is late for work.
