The era of compact and portable mechanical chronometers opened the invention are the same Huygens in 1675 rotary actuator, as well as the use of weights instead of springs. Compound torsion pendulum, a spiral spring and anchor running paved the way not only to marine navigation, but also the creation of massive small hours, but still significantly increased the accuracy of astronomical observations, and even found the uneven rotation of the Earth.

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. Some reports suggest the tenth century that it was time for the first time such a mechanism built monk from Herbert Orillaka, the future Pope Sylvester II (950 – 1003). Indeed, in the technique, it was a great talent, and it had the opportunity during his study tour to get acquainted with the principles of construction of various Arab astronomical Read the rest of this entry »
