What year and date was the first american clock invented?
In 1927 Warren Morrison developed a very large and accurate clock by testing the vibrations of a quartz crystal from an electrical circuit. In 1504 Peter Heinlein Nuremberg created the very first wrist watch in Germany.
Who invented the quarts clock?
In the 1920's the first Quartz were invented. This works by applying a certain voltage and pressure inside the clock. This will vibrate or oscillate the Quartz at a constant rate. This vibration moves the hands on the clock in a very precise manner, making them very cheap and very accurate. These are the clocks are used everyday in our houses, offices and schools and in many cases wrists. There are other types of clocks, such as atomic clocks, but these are not widely used and are not yet perfected.
Who invented the atomic clock?
The first atomic clock was invented in 1948 by the US Bureau of Standards.The first practical atomic clock was invented by English physicist Louis Essen in the 1955.Atomic clocks use the energy changes that take place in atoms to keep track of time. Atomic clocks are so accurate that they lose or gain no more than 1 second once every 2 or 3 million years.The most accurate, modern-day atomic clocks will neither lose nor gain a second in 168 million years.
How did clocks improved?
first there were wind up clock, the battery opporated clock, and now electric clocks
Did the first clock look like a modern clock?
No, the first clocks were not like modern clocks. They were simpler devices like sundials or water clocks that measured time using natural elements. It wasn't until the mechanical clock was invented in the Middle Ages that clocks began to resemble their modern form.
What was the first type of clocks?
The sundial was the first type of clock ever used
Who invented sand clocks?

Who invented the first clock in what year?
They originally used sundials in ancient times (no exact year). Some report water clocks as far back as 4000 BC. As for the very first clock, none of the first clocks survived from 13th century Europe so it is known conclusively who the individuals were or what the clocks were.
When was the first wooden clock created?

When was the first analog clock invented?
In Greek and Roman times, water clocks were used.
What are the contribution of Egyptians in the development of science?
They developed the first clocks (THE EGYPTIAN WATER CLOCK)
First clock invented?
The first mechanical clock was invented in Europe in the early 14th century. It was developed to track time for religious ceremonies. Prior to this, sundials and water clocks were commonly used for timekeeping.
Where does the clock come from?
It is unknown exactly where a clock comes from. The first clocks were called sundials and they have been used since ancient times.
Who created clock?
It is unknown who created the clock. The first clocks were known as sundials. They were used by using the sun to cast a shadow on the ground.
Who invented digital clocks?
the first digital clock was invented by Peter Petrov in 1968 The patent for the mechanism used in Pennwood and Lawson digital clocks was granted to Frederick A. Greenawalt, an employee of the Pennwood Company. Greenawalt's patent was issued in February 1935. Lawson stated selling digital clocks in 1934.
