A presentation that describes the original calculation of TIME and the creation of Clocks and Watches. It describes the type of the clocks and watches then compares these to people. Example, automatic watches need to be shaken to work, some people are the same. The list goes on.
1. Clocks & Watches Muawiya A. Abu Jubain
2. A Thought
"Space and time are modes by which we think, not conditions under which we live."
3. The Beginning of time
The Cro-Magnons recorded the phases of the Moon some 30,000 years ago.
4. The Beginning of time
The first minutes were counted accurately only 400 years ago.
5. How did it all really start?
The ancient Egyptians were expert astronomers who studied the Sun's recurrent movements and their effects on the Earth very closely.
6. How did it all really start?
By plotting the beginning of the Nile's flood each year, a reliable harbinger of seasonal change, they measured a cycle 365 days long.
7. How did it all really start?
Astronomers found that each year, on the appointed day, the star Sirius appeared about six hours later than the previous year. This quarter-day difference led them to adjust the solar year to 365.25 days.
8. The History of the Clocks
There is no agreement between historians on the history of the clock.
9. The History of Clocks
The word Clock was first used in the 14 th century.
It comes from the Latin word Clocca which means Bell.
10. The SUN is the 1 st clock
The first way that people could tell the time was by looking at the sun as it crossed the sky.
11. The Sundial Clock
The oldest type of clock is a sundial clock, also called a sun clock. They were first used around 3,500 B.C. (about 5,500 years ago).
12. The Sundial Clock
Since sundials depend on the sun, they can only be used to tell the time during the day.
13. The Water Clock
Around 1400 B.C. (about 3,400 years ago), water clocks were invented in Egypt.
14. The Water Clock
Water clocks worked better than sundials because they told the time at night as well as during the day. They were also more accurate than sundials.
15. Pendulum Clocks
The first practical clock was driven by a pendulum. It was developed by Christian Huygens around 1656. By 1700, the pendulum clock also had a minute hand.
16. Pendulum Clocks
One problem with pendulum clocks is that they stopped running after a while and had to be restarted.
17. Means to recharge a pendulum clock
Winding the Clock,
The first watch to exist was the Pocket Watch
19. The Automatic perpetual watch
The first one was invented by a Belgian watchmaker, Hubert Sarton in the 18 th century.
20. The Solar Powered watch
Light is the source of power
For this watch.
21. The thing about Clocks and Watches
What do we want from them?
Quality and Expensive Watches !!!
They are made to tell Time
Sun Dial Clocks Couldnt tell time
Water Clocks Need To Be Maintained
Every time the Water Finishes
Mechanical Clocks and Watches
Need to be Winded every once in a
Perpetual Watches need to be
Shaken Every Once in While
Solar Watches Need Only Light
Some Watches & Clocks Make Loud
Sound/Noise While Working
Some Clocks and Watches are used as
Some are used as Timers and Stop Watches
Some Clocks and Watches
Always Give you the Wrong
How About People?
The DAY Workers
The Status Searchers
Are they aiming to produce Quality Work? Are they aiming for the status?
