Clocks: From Sun Dials to Quartz Crystals

The video explores the evolution of timekeeping from ancient methods like sundials to modern quartz clocks. It highlights the significance of clocks in daily life and explains the mechanics behind different types of clocks, including pendulum, hairspring, and quartz clocks. The video also discusses the components of clocks, such as power sources, oscillators, controllers, and indicators, and how these have evolved over time.

• The change of seasons

• The flow of water

• The movement of the sun

• The phases of the moon

Which invention in the 16th-17th century allowed for more precise time measurements?

• Quartz crystal

• Digital controller

• Pendulum clock

• Water clock

What was the purpose of the hairspring developed in the 1670s?

• To power clocks using solar energy

• To provide precise movements in clocks

• To display time digitally

• To synchronize clocks with the moon

What is the primary function of quartz in modern clocks?

• To control the pendulum

• To provide energy
