The 10 ancient people do better than we do today (Part 1)

Our ancestors had extremely unique knowledge of metallurgy, mathematics, chemistry, astronomy and more.

A lot of people have been thinking about it since they were sitting in the school chair until graduation, the ancient people did not do much to leave for posterity, except for the paintings on the walls of the caves. So this is a wrong view, and many recent studies also confirm this. Our ancestors had extremely unique knowledge of metallurgy, mathematics, chemistry, astronomy and more. Here are ten examples of brilliant achievements of ancient civilization.

1. Irrigation and irrigation technology system

The problem of access to water is still very serious in many parts of the world. But did you know, the people of Lima City (Peru) solved this problem 1500 years ago?

Today in Peru there is a crisis in clean water supply. The heavily polluted water, along with the changing environment caused by humans, undermined the "freshwater security" of the country.

A water pit of the Huari people.

However, the Sedapal clean water company has proposed "reviving" the ancient stone canal system, which was built during the Huari culture in 500 AD, to provide clean, unpolluted water. infection.

The water inside is very clean and clear.

The Huari people created the perfect water storage system, by storing water from the rocky mountains during the rainy season. The collected water will be led down to the foot of the mountain by a channel system to maintain the water level of the rivers and streams in the dry season.

Unique water storage and conducting system.

Many ancient advanced civilizations have known devices to store and store drinking water. Persians, Nabateans, Romans, Haraptsy also built their own system of canals, water pipes and huge sewers.

2. Steel training

From 2,000 years ago, the ancient people in Levant used a unique technology to forge sharp-edged weapons. Many swords, daggers and axes built with this steel-making technology are still available today, and are an unexplained mystery for modern steel masters. It is thought that the steel making formulas have been lost, sadly, the modern metal processing technology does not produce the same kinds of steel as the ancient steel that the ancient people had built.

Damascus steel is produced from Wootz steel material originating from Asia.

Damascus steel is produced from Wootz steel material originating from Asia. This unique type of steel features striking metallic veins with splashes like flowing water. The swords made from this steel are famous for being very firm, very hard to break, good elastic blades and can be sharpened. Damascus steel was first recorded around 300 BC, and the steel was mass-produced in the Middle East between 1100 and 1700.

The secret of Middle Eastern Damascus steel has only been elucidated when science developed.

The secret of Middle Eastern Damascus steel has only been elucidated when science developed, through testing of samples by electron microscopy in modern laboratories. However, the current techniques and materials to try to reconstruct this type of steel are not successful or it is true that the material produced does not completely match the remaining steel samples despite some similarities.

3. Concrete

Colisée Arena - one of the ancient Roman architectural masterpieces.

The life of modern concrete structures is about 100-120 years. So the 2000-year-old concrete buildings built by the Romans retain their integrity to this day. So what is their secret?

The Romans produced concrete from mixtures: lime, volcanic rock and sea water. The lime reacts with the ash, making the mixture solid.

Seawater used in the manufacture of concrete has a perfect tobermorite crystal structure (Ca ₅ Si ₆ O ₁₆ (OH) ₂ * nH2O) and great durability.

Roman concrete is cleaner and more environmentally friendly than modern concrete . Cement types widely used today require heat treatment (heating a mixture of limestone and clay up to 1450 ℃). This production stage produces a significant amount of carbon into the air. Roman cement has less lime than modern cement, and it only requires burning at 900 ℃, which means less fuel and fuel.

The Pantheon is a large concrete structure that has existed for nearly 2,000 years.

4. Construction of roads

Today, if the highway is completed in just one year, it is considered a great success. Our ancestors have long understood the importance of communication between cities and they built roads very quickly.

This magnificent road has sections up to 20 meters wide (66 ft).

Qhapaq Ñan (English: Inca Major Road, or Main Road Andes, meaning "beautiful road" is the main " North-South " highway of the Inca empire along the 6,000km (3,700 miles) of the Andes spine The Inca road system is linked with a total length of about 40,000km (25,000 miles), providing access to more than 3,000,000 square kilometers (1,200,000 mi²) of territories.

The Incas used this road system for many different purposes.

Located between a height of 500-800 meters (1,600 to 2,600 ft) above sea level, this magnificent road has sections up to 20 meters (66 ft) wide, connecting residential areas, administrative centers, agricultural and mining areas as well as religious, ritual and sacred centers.

The Incas used this road system for many different purposes. Not only is the road providing transportation for people traveling through lands, this road also provides many other purposes that are extremely important for the Inca empire such as military and trade. and religion stretches through the territories that today are Argentina, Bolivia, Chile, Colombia, Ecuador and Peru.

A road built by Romans.

Romans are also called experts in road construction. The roads built by Romans estimated an area of ​​about 4.4 million square kilometers. They are made from extremely hard gravel, soil, bricks, granite and lava volcanoes. Some of them are still in use until today.

5. Crafting stone

We still see examples of stone cutting today with the high precision of ancient masters. This is indeed a challenge for modern stone manipulation experts. At the Puma Punku archaeological site in Bolivia there are 15,000-year-old stone slabs that are beautifully sculpted and carved.

The work at Pumu Punku is made up of granite and diorite stones.

What surprised the scientists was that the works at Pumu Punku were made of granite and diorite stones - rocks with hardness only lost to diamonds and were almost impossible to craft with ancient techniques. However, the blocks in Puma Punku are cut and paired perfectly. Many rocks here have smooth surfaces like a sheet of paper, with straight grooves with absolute uniform depth and sinking screw holes with a diameter of only a few millimeters inside.

Every attempt to replicate a copy of the monument failed.

On the surface of stone slabs there was no trace of crafting. The builders also said that, in terms of the complexity and the high technical requirements of the building, the pyramids in ancient Egypt were too simple compared to the ruins of Puma Punku when each block of stone here wished. weighs up to 800 tons. Every attempt to replicate a copy of the monument failed.
