Purpose & Scientific Principle
By restoring sundials, hourglasses, mechanical clocks, quartz clocks to atomic clocks, the audience can actually experience the accuracy of various timing devices, understand concepts such as atomic clocks and Planck time based on quantum mechanics, and understand the ultra-high accuracy of atomic clocks and their importance to the development of quantum technology.
How to Operate
The exhibition items consist of sundials, hourglasses, mechanical clocks, quartz clocks, atomic clock models, timers, multimedia consoles, etc. The audience can operate the real objects or models one by one, such as flipping the hourglass model, adjusting the length of the pendulum, etc., to understand the working principle of human timing tools and the development of timing accuracy, compare the errors of various timing devices, and realize the great superiority and importance of quantum timing.
The clocks and watches that people use daily have a high-precision error of about 1 minute per year, which has no impact on daily life. However, in high-demand production and scientific research fields, more accurate timing tools are needed. The most accurate timekeeping tool in the world is the atomic clock, which appeared in the 1950s. Atomic clocks use electromagnetic waves emitted when atoms absorb or release energy to keep time. Because this electromagnetic wave is very stable and controlled by a series of precision instruments, the timing of the atomic clock can be very accurate. The elements currently used in atomic clocks include Hydrogen, Cesium, Rubidium, etc. Atomic clocks are accurate to only 1 second every 20 million years. This provides a strong guarantee for astronomy, navigation, and space navigation. By displaying the principles and accuracy of various timing devices in history, this exhibition reflects the importance of timing accuracy and the huge boost that quantum technology has given to timing capabilities.
