Question

People started making clocks when they needed to organize their time better. They had calendars for months and years. But they needed to track time during the day. Early examples of clocks included sundials that measured the movement of the sun across the sky. Then came the idea of burning objects at a certain rate, such as when candles, oil lamps, or incense would burn past marked lines or knotted cards.Modern clocks meet the same need with advanced technology. In the 1600s clocks were made with a mechanical balance wheel, and progressed to a pendulum, like you see in grandfather clocks. Today most clocks use vibrating quartz crystals, or atomic waves.

Summary:Highlight the central idea in red. Highlight key details in blue.

Answer 1

Timekeeping devices have evolved from ancient calendars and sundials to the modern atomic and quartz clocks, driven by humanity's need to accurately measure and manage time as per Earth's rotation.

Step-by-step explanation:

The student's question highlights the historical evolution of timekeeping devices, from early calendars and sundials to modern atomic and quartz clocks. Calendars, originally designed by early priests of civilizations like Babylonia and Egypt, have been an essential tool for tracking seasonal changes vital for agricultural practices. this need for precise time management led to the development of various clocks over centuries.

Early timekeeping methods included sundials, which used the sun's position, and candle clocks, where burning candles marked time with lines or knots. With the discovery that Earth's rotation could be used for time measurement, mechanical clocks with a balance wheel came about in the 1600s and were later improved with the invention of the pendulum.

As the world progressed, the need for more accurate timekeeping resulted in the adoption of clocks powered by vibrating quartz crystals and atomic waves, offering precision far beyond older methods. Timekeeping inventions have greatly influenced the organization of society and work, such as the time clock patented in 1888, which introduced the term "punching the clock" for tracking employees' working hours.
