Good morning to everyone, I would like to express my gratitude to the principal, the teachers, and my friends for letting me tell you about the clock. A clock or a timepiece is a device used to measure and indicate time. It is one of the oldest human inventions, meeting the need to measure intervals of time shorter than natural units.

Devices operating on physical processes have been used over the millennia, such as sundials, water clocks, and duration timers. The invention of the verge escapement made possible the first mechanical clocks around 1300, and the pendulum clock by Christiaan Huygens in 1656.

Electronic clocks were first introduced in the 20th century after the electric clock was developed in 1840. Analog clocks indicate time with a traditional clock face, with moving hands, and digital clocks display a numeric representation of time. Speaking clocks state the time audibly in words, and there are also clocks for the blind that have displays that can be read by touch. Thank you.
