One may not imagine that ancient civilizations have witnessed strong technological progress, but perhaps they were more advanced than the current era, and there are some indications that archaeologists discovered, and after studying and analyzing them, it was found that the ancients in more than one civilization witnessed a strong development in the field of technology and inventions. Such as electricity, balloon, etc.

Baghdad battery:
Did the ancients discover electricity in Iraq? During the work of a German mission in 1938 in Iraq in the Khogut Rabo area in southeast Baghdad, the mission team, including the German (Wilhelm Koenig), discovered a 13 cm long clay jar with a copper cylinder and covered with an iron rod, but the mission team did not He could explain the functions of that jar, but some opinions suggested, after careful examination, that this formation was used in the past to generate electricity, and this was the reason for calling it the Baghdad Battery.

Its age was estimated at about two thousand years, this distinguished archaeological discovery indicated the reality of the experience and knowledge of the ancients about how they generated electricity, which later caused a state of curiosity among archaeologists since it was found in an attempt to find out what was going on Regarding the generation of electricity at such a time, especially after the pioneers of the German mission discovered ten other tractors with the same configuration and installation under Iraqi territory.

While the mission team toured in Iraq, they also discovered a number of silverware covered with a thin layer of pure gold, and that was after they found the Baghdad battery, which (Wilhelm) suggested that it was used to paint these crafts with gold, through its primitive generation of electricity by Through some copper and iron wires, along with liquid materials such as wine, squeezed lemon, or even vinegar, any acidic solution is used to generate the electric current.

The remains of some liquids were indeed found in those jars, but any discovery must face criticism. Many objected to what (Wilhelm) revealed and that Iraq had known electricity two thousand years ago, while others admitted that these jars are only signs of the amazing progress it has reached. The ancient civilizations that preceded us, and that we are not really the first as we claim, and among them was the professor of history of science and technology at Smith College in the United States of America, called (Marjorie Senal), who conducted a number of experiments with her students using those jars and the technique of their installation.

They were able to generate through it only one volt, but it was able to prove that these jars were generators of electricity, which means that the concept has existed since ancient times. Ancient China also knew air balloons, hot air balloons that are currently used in recreational trips, etc., existed in the ancient Chinese civilization in the third century BC, where the Chinese used them to send messages through small copies of them.

It was a good means of communication between the Chinese in scattered places, and he called it the sky lantern, due to the blazing fires making its lights. The sky lantern in the ancient Chinese civilization had several uses, including: Communicating a message to someone in a remote location, or a request for help during wars, or as entertainment such as modern fireworks, as some people used when they got lost

This technology has been used until now in China, for various recreational purposes now. The military expert, Zhou Liang, was the first to use this technique of paper and fire, from the beginning, relying on the fact that hot air would be lifted by cold air, and the matter developed to manufacture a number of luminous lanterns, which confirms China's progress and discovery of inventions that we consider modern, and they are as old as time immemorial.
