The 10 ancient people do better than we do today (Part 2)

Agricultural systems and wastewater treatment in Mexico's floating gardens are so advanced that despite efforts to recreate it in today's times - every attempt fails.

In the previous period, we came across five things that ancient people did better than we do today. Scientists are still actively studying the great achievements of ancient civilizations, and we continue to come to the next 5 things that people with modern machines and technological advances Today still have to restrain their hats to their ancestors.

6. Agriculture

When thinking about the Aztecs and other Central American cultures, the first image that often appears in our heads are sacrificial rituals of living people or cattle - influences from Hollywood movies. However, when studying these civilizations, scientists also discovered many other interesting things, especially the chinampa agricultural system , also known as "floating gardens". They can be found on lakes in Mexico Valley.

Chinampa agricultural system, also known as "floating gardens".

A rectangular-shaped chinampa garden was built on the muddy lake. At first, people blocked this area with piles, then filled the interior area with dirt and rotting vegetation. This layer of mud must be higher than the lake level to help the stumps from flooding. The canals surrounding the chinampa plots create the feeling that these agricultural lands are floating on the water, so it is mistakenly referred to as "floating gardens" . To fix these lands, the Aztecs planted many willow trees around. The dense willow system over time will make the walls of the garden structure more solid, reducing the impact of erosion.

Chinampas gardens for bumper crops throughout the year thanks to water supplies are always provided with air conditioning. A complex drainage system including dams, sluices and canals was built to deal with the problem of rising water in the rainy season. Aztecs use human compost to compost items for fertilizing crops. This is both good for plants and good for the city environment because waste is treated.

7. Building stone walls

Famous Inca civilization of advanced stone processing and arrangement technology. Many of their works still stand today and become tourist attractions in Machu Picchu and Sacsayhuaman in Peru.

Huge blocks of stone are carefully scrubbed to match and dry.

Huge blocks of stone are carefully scrubbed to fit together and dry grafting (not using a bonding agent such as mortar, concrete, .) forming walls with precision unlike anywhere in Europe. America. They were so close together that even a piece of paper could not pass through between the stones. This accuracy, with a combination of rounded corners and a variety of interlocking designs of blocks, and how the walls tilted in (to reduce damage in the case of earthquakes) made Scientists confused for decades.

Extremely solid stonework walls are still a mystery.

The method that the Incas used to connect adjacent stones is still a mystery and the efforts to reconstruct these techniques have not yielded any results.

8. City planning

In the last century, modern scientists as well as urban planners were astonished when many ancient cities were unearthed, revealing a level of "unprecedented" planning in history.

The old city has an outstanding level of planning and amenities.

Archaeologists have discovered the 5,000-year-old Mohenjo Daro city in Pakistan. With what they found here, there has never been before: an exceptional level of planning and comfort. All houses are equipped with bathrooms built of bricks, many houses also have toilets. Wastewater from the bathroom is directed into a solid brick sewer system that runs along the center of the street, above it covered with bricks or stone slabs.

Water tanks and wells are sophisticatedly constructed with wedge-shaped bricks that contain a supply of public drinking water. At that time, the city had an estimated 40,000 inhabitants.

At that time, the city had an estimated 40,000 inhabitants.

Scientists believe that another major city, Caral, is located in Peru's Supe Valley, which was built at the same time as Mohenjo Daro. Following the remnants of the remnants can see the extremely high level of architects of the time - pyramids, squares, stages, temples, and many residential areas. Caral people already have developed agriculture, a varied diet, already know how to use textiles and garments, and have complex accounting and recording systems. People here know how to build water supplies and develop dense irrigation systems.

Caral ancient city - Peru.

Modern architects still go to Caral to find inspiration about city planning. Japanese architects intend to incorporate Caral people's home design into modern architecture to protect people from earthquakes. Caral people hang their houses in stone-filled baskets to overpower the movement of the soil and prevent collapses.

9. Astronomical research

How about a map of many ancient tombs in Japan?

Ancient civilizations in the world have long possessed extraordinary knowledge of the universe and its movement. Evidence is the constellations painted on ancient Greek ceramics, Indian stone carvings depicting the Lower and East solstice points.

In many ancient Japanese tombs, a stellar map is found, the Australian aborigines still circulate stories of world creation and important astronomical events. But how can ancient people record such accurate and accurate cosmic events while not having the same modern technologies as ours today? This is still a mystery beyond the knowledge of scientists.

How can ancient people record such accurate and accurate cosmic events?

Recent discoveries show how ancient ancient cultures pioneered astronomical knowledge, and certainly their level of knowledge goes far beyond the primitive humanity that we have previously thought about they are like that.

10. Making weapons

Modern weapons today far outweigh the ancient weapons of destruction and damage. However, many ancient weapons still surprised scientists because of their structure and power.

Many ancient weapons still surprised scientists because of their structure and power.

Greek mathematician, engineer, inventor, and astronomer - Archimedes (287-212 BC) is thought to have created the heat-ray weapon (sometimes referred to as "death ray"). " ) to protect Syracuse - the historic city in Sicily against the attack of enemy ships. According to second-century author Lucian SCN and mathematician Anthemius came from Tralles a few centuries later, this weapon was created from strong light reflectors (polished copper or tin plates). People used them to focus sunlight on enemy ships as they approached and caused them to burn.

Although this weapon is still a controversial topic among historians, many experiments have demonstrated the viability of this weapon. In 1973, Ioannis Sakkas, a Greek scientist, gave up 70 covered mirrors to a plywood model of a Roman warship 50 meters away. When the light reflected from the mirrors converged on the ship, it caught fire in seconds.
