The wheel is in the service of man

From the waterwheel, the water lever..
To the wheel that grinds grains..
To the turbine, the electricity maker.

People are now talking about technology, which is the characteristic of this time, and through which the way of life on this earth has been transformed in an unexpected way. But they talk about it as if it were a feature of this time alone, and it is not a feature of this time alone. The technique began from the day man began to live his life on this earth: a tree with fruit that he picked with his hand, for his food, or he climbed to it with his hands and feet and running water came down to it in its course for his drinking, or he picked it while descending. Nothing helps him in any of this except his sight, his hearing, his smell, his senses, and his muscles. If he wants to dig the soil, he has no tool other than his fingers.

How quickly he found that his fingers were too soft to dig, too weak to strike, and too short to be long, and so he turned to the nature around him and was mesmerized by what it could offer to help him. In its wood. In her lap. Little by little in its rocks and minerals.

Those are the first machines.
This is the technique in its alpha and its epidemic. It does not prevent it from being called a teknikya because our present teknikya has reached the levels of progress to the Raa and the Zay, and that it is on its way forward to what God wills by having letters that reach it, the last of which are the Haa and the Yaa.

The arrow shot by the ancient man is a technique.
The hammer with which he broke the stone is a technique.
And the tree trunks that he joined together with a tree tie, and he ran with them while he was above them, above the water, so it was the first ship, this is a metaphor.

Years pass, centuries follow, and the tools are of many types, many goals, and diverse purposes. It has to build ancient civilizations. A civilization arises and then disappears.
The basis of each of these civilizations is the technology that its people had.
Even when the Christian era came, we read in history about an ancient engineer writing about technical engineering, classifying the tools that man of this era had collected, and returning them all to six principles, which are:

Lever
Wheel & Axle
Pulley
Wedge
Helix (1) Screw

As for the ancient engineer, he is Hero, the scientist who lived in Alexandria in the early centuries of Christianity, and he was one of the men of the famous library, the Library of Alexandria. The Library of Alexandria was not only a library for storing books, but also...
It was something similar to a modern university, with professors, teaching, and research conducted. Its language was Greek, and most of the people in it were Greek.

This engineer, Hero, left books that still exist today, on identity, mechanics, engineering, and other things.

He did not enumerate the tools that existed in his time, but rather he attributed them to six things that he considered to be their origins. The difference between the two expressions is significant.
