History and Evolution
Background:

It´s one of more common to find at home
Was a simple idea as the pendulum swings left and right it turns a wheel with many pine nuts on it.
By English physicist Louis Essen in the 1950's
Atomic clocks use the energy changes that take place in atoms to keep track of time.

Are so accurate that they lose or gain no more than 1 second once every 2 or 3 million years.

It´s top of line
The projector clock has lots of interesting and informative features that helps you and give you the right time.
The clock projects the hours by a laser through a small LCD screen, and have a high tech.
By Peter Petrov in 1968
Thomas Eddison invented the digital clock after Albert Einstein thought it up.
The people could tell time easier and is innovative...
Why were clocks invented?
Desired was for navigation purposes.

Efficient apparatus to measure the time

Calculate or register events in the history.

Organize the life activities .

Seconds, Minutes, Hours, Days, Weeks, Months, Years.

The time is the same in all the world, and the clock is exactly.
Water Clock
Made from two containers of water one of higher than the other.

One could say that no one invented it, but that it was discovered.
Was created by the Venetians.

Its recognition goes back as far as the 14th century.

The Hourglass
Alarm clock

An old adage says :
"He who gets up early, God helps him"...
Was an inefficient clock..
It´s efficient
Uses...
The time is the same in all the world, and the clock is exactly.

Arrive to class

Organize the things to do at the day.
Wristwatch
The First War World, the soldiers and the pilots attached their watches to their wrist with a leather strap.

They used their watches like flying instruments
