In addition, many scientific investigations require a mechanical timekeeping device to carry out specific time measurements. These types of clocks are still widely used today for transportation schedules, the Internet, TV schedules, GPS, aviation, and financial markets. Having said that, it can be used at any time of the day or night – even in the most extreme weather conditions. When compared to atomic clocks, the mechanical clock is less accurate.
Mechanical clocks comprise an oscillator that measures the passing of time. But they are also used for synchronizing time in GPS, electric power grids and smartphone watches. These clocks are designed to measure the exact length of a second by combining a quartz crystal rhythm movement for greater stability.Ītomic clocks are mostly used in NASA for onboard GPS satellites that orbit the Earth.
AtomicĪtomic clocks are devices used to measure frequency in electron, microwave, and electromagnetic transition of atoms. Now that you have a basic idea of how clocks work and where they come from, take the time to read the rest of this article and learn about the different clock mechanisms, clock features, and the most popular types of clocks that are still used to this day. The displayed time indicator is in a readable format that can easily be understood. The counter chains are then used to show the readings of seconds, minutes, and hours. This rhythmic back and forth movement moves at a certain speed over and over again. Whether it’s a battery, suspended weight, or power line, all clocks use a regular rhythm movement to measure time. How Do Clocks Work?Ī clock can only work when it has a primary power source. In 1929, the quartz clock became highly popular as a wrist watch and portable clock. Next came the Grandfather clock around 1700, and in 1775, the cuckoo clock was invented followed by the electric clock in 1840. By 1652, the pendulum clocks became the world’s most precise time measuring devices and were the most widely used across the globe.
However, with the advancements in technology, more accurate clocks were invented. Although the sundial wasn’t a very accurate way of telling time, it was, nevertheless, used for almost 2,000 years. The time of the day was read through the position and length of the shadows on the markings. The sundial consisted of a vertical metal stick on a horizontal surface that was marked with morning, noon, afternoon, evening, and night. It all started with the direction of the sun using a sundial to tell the time. Marine, weather station or maritime clockĬlocks are possibly the oldest human inventions that date back as early as 1300 when the first mechanical time measuring device was invented in Europe.
