Since long before there were clocks, time is measured through lands end long island the observation

Since the first careful observation of the sun, the man proposed master time. Calculations and tests, over the centuries, were falsified to make way for the instrument to measure the time: the clock. In this race, the Catalans also had a small role.
Since long before there were clocks, time is measured through lands end long island the observation of solar and lunar cycles. It became the first calendars, especially for agricultural purposes. But, with all the will of man to count fractions day more accurately made necessary clocks. The inhabitants of ancient Egypt were the first to succeed in the challenge of measuring how advanced the time during the day. The first system was the sundial, whose basic form was a style that projected lands end long island shadow on a rule. It has found a fragment of the fourteenth century BC is now in the Berlin Museum.
But sundials failed; every night and every step of a cloud. So the race to keep track of time continued to give rise to new techniques that worked in the shadows and darkness.
Thus were born the water clock water clocks or water clock, which is also known from ancient Egypt. The oldest lands end long island is found clepsidra Karnak, the fourteenth century BC (kingdom of Amenhotep III), which is currently the Egyptian Museum in Cairo. The system is very simple, but has autonomy. It consists of a container filled with water with a conical hole very close to the base, which was emptied lands end long island steadily -the record is clau- and points depending on when the water level and marks made interior wall. The Egyptian water clocks were twelve hours.
Clepsidra reached the Babylonians and Chinese and also in Europe, through the Greeks, they continue to evolve the invention. The Greeks and Romans used these devices as stopwatches for measuring the duration of the public interventions, thus limiting their uncontrollable verbosity speakers. The best water clocks, however, were the Arabs, who joined automatons and sound elements activated systems balances and water tanks. Legal changes even earlier. Treaties Al-Muradi eleventh century and Al-Jazzari in the thirteenth lands end long island century attest. At that time, technologically, lands end long island the Arabs were much higher. lands end long island So when Alfonso VII dominated Toledo in the twelfth century and ordered to dismantle a water clock astronomical Arabic to understand the operation, what happened was predictable ... that nobody knew reassembling. However, in discharge of the royal contribution to science, saying that a key document for historians of the clock due to a collection of compiled knowledge to the court of Alfonso X the Wise: the Libro de los relojes belongs to the collection lands end long island of knowledge of astronomy Books.
Throughout history, different cultures of the world have been able to devise many different types of clock. After sundials and water came in many others. Ben watches are curious aromatic China, which worked with the use of incense at a constant speed, and even smell different for each time of day. Or other kinds of watches of fire, such as fuse, the Egyptians used in the tombs; lands end long island or candle clock, Alfred the Great, king of Wessex, was used in the ninth century to know when the prayers brands wax. And even this endless creativity, variety and evolution of the clock stopped with the arrival of a new revolutionary invention: the mechanical clock.
The pure mechanical mechanical watch does not arrive lands end long island until around 1300. It was probably lands end long island developed in northern Italy, although it is not known exactly. His main contribution was the autonomy could indicate the passage of the hours without relying on any natural element. Just had a stone tied with a rope, which was the driving lands end long island force constant watch missed a sustained rate through a brake inertia. Its main drawbacks were that occupied much space and was not accurate enough, was adjusted daily.
Among the first copies of the new invention include the clock tower of the Cathedral of Norwich (England), lands end long island who built Stroke Roger between 1321 and 1325. the new technology quickly lands end long island spread throughout Europe and in the same century XIV the aspiration of all people was important to have a good clock in the cathedral towers or civil (the king's palace, government, noble houses, etc).
At first mechanical clocks had no needles or sphere only sounded the bells, or by Jacquemart automata. The invention improve very slowly, and in fact, almost like watches continued for a long time, with the sole addition of the sphere and the ag
