what is clock and what is its history.docx

the clock is not just a time to see the device but also a decoration piece. Its presence and its history are very interesting. The first alarm clock is invented by Levi Hutchins in 1778.

1. what is clock and what is its history
Definition: Any object by which time is measured is called a clock.
There are different types of clocks in different eras. Some types of clocks are as follows:

1. Sundials.
The position of a shadow on a (often) flat surface with hourly marks is displayed by a sundial to indicate
the passing of time. In ancient times, sundials were commonly used. Up until the 1830s, sundials were
still employed to keep track of how well clocks worked.


2. Water clocks that work mechanically.
Archimedes, a famous engineer, scientist, and mathematician, created the earliest clock with gears that
is known to exist in the third century BC. A cuckoo clock with singing and moving birds every hour was
made by Archimedes and was also an astronomical clock [18]. A person who is startled by the singing

2. birds is seeing the first carillon clock play music at the same time that it is playing. The mechanism of the
Archimedes clock consists of four weights, counterweights, and strings, which are controlled by a system
of floats in a water container with syphons that control the automated continuation of the clock. The
mathematician and scientist Hero [19] describes the workings of these kinds of clocks and claims that
some of them use a chain to move a mechanism's gear. [20] Procopius wrote about another Greek clock
that was apparently built during Alexander's reign at Gaza. [21] A Meteoroskopeion, or a structure that
displayed the time and celestial phenomena, was most likely the Gaza clock. Similar to the Archimedes
clock, it had a pointer for the time as well as certain automations. At night, a lamp becomes visible every
hour, and 12 windows open to mark the time. There were twelve doors that opened one at a time, with
Hercules finishing his work at twelve, the Lion at one,

4. and so on.



3. Astronomical.
Sui Song, a Chinese polymath, created the "Cosmic Engine," the first completely mechanical water clock
in history, which was built in China in 1092. This enormous astronomical hydro mechanical clock tower
was about ten meters (30 feet) high, had a clock escapement, and was indirectly powered by a rotating
wheel with falling water and liquid mercury. It also used an armillary sphere that could calculate
challenging astronomical equations.


4. Pendulum in 1656.
The pendulum clock was created, which marked the next advancement in accuracy. Galileo came up
with the notion of controlling the motion of a time-telling gadget with a swinging bob earlier in the 17th
century. However, the inventor is typically acknowledged as Christiaan Huygens. He developed the
mathematical equation that connected pendulum length to time (approximately 99.4 cm or 39.1 inches

5. for the one-second movement) and had the first pendulum-driven clock manufactured. The Hague
produced the first model clock in 1657, but the concept was first developed in England. William
Clement, an English clockmaker, developed the longcase clock, popularly known as the grandfather
clock, in 1670 or 1671 to hold the pendulum and workings. In this period, clock faces started to be
fashioned of ceramics that had been hand-painted, and enamel started to be used for clock cases.

6. 5. Early electric.
Francis Ronald’s published the first electric clock that used dry pile batteries in 1815. [59] The electric
clock was created in 1840 by Scottish clockmaker Alexander Bain. Either an electric motor or an
electromagnet and armature are used to wind the mainspring of an electric clock. He issued the initial
patent for the electromagnetic pendulum in 1841. By the end of the nineteenth century, the
development of the dry cell battery made it possible to power clocks with electricity. Electromechanical
clocks are those that use electricity, either alternating current (AC) or direct current (DC), to wound the
spring or increase the weight of a mechanical clock. Clocks that use an electrical impulse to move the
pendulum would also fall under this group. Electrical energy is not used to keep time in
electromechanical clocks. Although these clocks could be used as standalone timepieces, they are more
frequently utilized as a master clock and slave clocks in synchronized time installations in educational
institutions, workplaces, factories, railroads, and governmental buildings.

7. 6. Quartz.
In 1880, Jacques and Pierre Curie discovered that crystalline quartz possessed piezoelectric
characteristics. [60] [61] Alexander M. Nicholson created the initial crystal oscillator in 1917, and Walter
G. Cady constructed the initial quartz crystal oscillator in 1921. ([3] At the Bell Telephone Laboratories in
Canada in 1927, Warren Morrison and J.W. Horton created the first quartz clock. The ensuing decades
saw the development of quartz clocks as precise time measurement tools in scientific settings, but their
practical application outside of these settings was constrained by the bulky and sensitive counting
circuits that were constructed with vacuum tubes at the time. From late 1929 until the 1960s, the
National Bureau of Standards (now NIST) used quartz clocks as the basis for the American time standard
before switching to atomic clocks. The Astron, the first quartz wristwatch ever made, was created by

8. Seiko in 1969. As a result, quartz clocks and watches have become increasingly common as a result of
their built-in accuracy and inexpensive production costs.

7. Atomic.
At this time, atomic clocks are the most precise timepieces available. They may be precise to a few
seconds over trillions of years, which makes them significantly more accurate than quartz clocks. Lord
Kelvin proposed the original theory of atomic clocks in 1879. A useful approach for doing this was
developed in the 1930s thanks to the invention of magnetic resonance. At the U.S. National Bureau of
Standards, a prototype ammonia maser device was created in 1949. (NBS, now NIST). It served as a
demonstration of the idea, albeit being less precise than current quartz clocks. In 1955, Louis Essen at
the National Physical Laboratory in the UK created the first precise atomic clock, a cesium standard
based on a specific transition of the cesium-133 atom. The hemisphere time scale was utilized in the
calibration of the cesium standard atomic clock (ET). Ytterbium clocks, which are accurate to fewer than
two parts in one Quintilian (2 10–18), are the most reliable atomic clocks as of 2013.

8.Present clock.
The present clocks are much more useful and updated than the old clocks. The present clocks work with
simple batteries, and these clocks have different designs. Before the invention of the alarm clock, people
hired a man who knocked on the door at morning and people had to get-up. People now use alarm
clocks for that purpose. In this era, people have digital clocks and alarm clocks on their mobile phones.
But the alarm on the mobile phone cannot make a big noise. That's why most people use table alarm
clocks because they can produce a lot of noise. IF you want to buy a best alarm clock then you can buy

with a spy camera. People use this clock at home, school, and office. Can people use this clock for any
illegal purpose? If people use this clock for any illegal purpose, then they are responsible, not the
company that made this clock. The most usable form of clock is the watch. A watch can be worn on hand
easily and time can be seen easily. In this era and since the invention of the watch, wearing a watch is a
fashion. Most men wear the watch. Some clocks and watches are more expensive than simple cars.

9. A clock is the beauty of the home, office, school, and shop. It increases the beauty of every place.

(How to buy a best clock)?
You should read the following buying guide to buy a clock.
1: What is the ideal size for a wall clock?
For a medium-sized wall, people should choose a medium-sized clock. For a medium-sized wall, people
should choose a clock that is between 10 and 18 inches in diameter. Also, for a large wall or a large hall,
the clock should be at least 24 inches or 30 inches in diameter. Choose a textured pattern that stands
out, such as an artistically carved wooden frame or a textured wallpaper.
It has a vibrant, hand-painted metal frame that really stands out.
2: How do you pick the proper style of wall clock?
There are numerous designs available on the market. If your home is decorated in a modern style, you
should choose a clock with a modern design, such as a digital wall clock or a singing bird clock. Also, if
you have an old conventional design, you can use it.
3: What materials are used to make wall clocks?

10. Plastic is a cost-effective material. It comes in a variety of shapes and sizes, including thin and thick
plastic. Thin plastic is less expensive than thicker plastic. Plastic comes in a variety of colors, making it
easy to complement any interior design style, but it does not endure as long as other materials like
wood or metal.
4. How do you pick the perfect color for your wall clock?
One thing to remember is that the color of the clock must contrast with the color of the wall. If your
walls are plain white, choose dark, striking hues. Choose a lighter-colored wall clock if your wall color is
dramatic. Make sure the color of the clock you choose complements the other colors in the room.
5. How much should a clock cost?
The cost of a clock made of thin plastic with a simple or outdated design may range from $20 to $50,
while the cost of a clock with a fresh design may range from $60 to $95.
If the clock is constructed of thicker plastic and has an old design, it will cost between $100 and $120,
and if it has a current design, it will cost between $125 and $160.
The cost of a clock made of metal or wood is more than a clock made of plastic. It might cost between
$180 and $220. However, there are numerous clocks in various shapes and colors. Their prices vary
according on the design, color, size, and material used, and can range from $20 to $350.
