The more developed the transatlantic communication, the urgent problem of ensuring the unity of timing on different sides of the ocean. In this situation vozimye clock is not a century. And then came to the aid of electricity, in those days called galvanism. Electric hours solved the problem of synchronization over long distances – at first on the mainland, and then between them. In 1851 cable, which formed at the bottom of English Channel, in the 1860-meters – the Mediterranean Sea, and in the 1865-meters – the Atlantic Ocean. And since 1899 began the era of signals of exact time on the radio. (more…)

Sun, water and fire hronometricheskie devices have completed the first phase in the development of instruments for measuring time. Gradually produce a more precise picture of the time, and have sought better ways to measure it. Revolutionary invention marked a completely new stages of development in this direction was the creation of the first wheeled clock, which began with the emergence of the modern era of timekeeping.

The author and the date the invention of mechanical watches is unknown.

Interesting annular solar watches, one of the options for the road – and they both served as decorative pendants. The main part was brass ring of a few centimeters in diameter, combined with other mobile ring equipped with a hole to the solar beam. At the outer surface of the main ring engraved initials months, but against them on the inner surface, was the hour scale. Before the measurement it was necessary to rotate the lower ring, so that the hole for the beam was the name of the desired month. To measure the time clock exhibited so that the ray of sunlight passed through the hole and said hour scale. The first description of the hours – in a ring with a seal – in the book doctor Bonn, was published in Paris in 1500. (more…)
