They respectively named the important contributions made by the four ancient civilizations to human

Hua Tuo invented hemp boiling powder.

1.Ancient Egypt: ?1) Architectural and geometrical aspects:

The industrious and intelligent people of ancient Egypt built great buildings such as the pyramids and the Sphinx. Especially in the construction of the pyramids, it reflects the amazing rich geometric knowledge of the ancient Egyptians2) Textual aspects:

As early as around 3000 BC, the Egyptians invented hieroglyphs, which laid the foundation for the later alphabetic writing. ?3) Astronomy:

The ancient Egyptians formulated the world's earliest calendar, dividing the year into 12 months, 30 days per month, and 5 days at the end of the year, for a total of 365 days 2.Ancient Babylon: ?

1) Legal aspect: In the 18th century B.C., in order to protect the interests of the slave-owning class, Hammurabi, the king of the ancient kingdom of Babylon, formulated the first relatively complete written code in ancient times in the world - the Code of Hammurabi2) Architecture:

The Hanging Gardens of ancient Babylon are also known as one of the Eight Wonders of the World3) Mathematics and astronomy: Notation uses decimal and sexagesimal methods, and in the field of algebra they can solve equations with 3 unknowns

In astronomy, it is possible to distinguish between stars and planets, and also name known stars. At that time, the calendar was the lunar calendar, the year was divided into 12 months, a day and night were divided into 12 hours, in order to adapt to the rotation of the earth, a leap month was also set up, which could be the first solar and lunar eclipses and planetary opposition 3.

Ancient India: ?1) Religion: Ancient India was the birthplace of Buddhism, one of the three major religions in the world.

Buddhism was later introduced to China and Southeast Asia, where it had a wide impact throughout Asia2) Literature: Created the immortal epics "Mahabharata" and "Ramayana".

3) Philosophical: The science of causation was founded, which is equivalent to the current science of logic4) Natural Sciences:

Created 10 numeric symbols, including 0, which are universally used in the world5) Agriculture: Cotton, wheat, etc. are planted, and the cultivation of cotton and the production of cotton fabrics are the earliest in the world

6) In addition, ancient India also had a high level of bronze alchemy, pottery, textiles, and vehicle and ship manufacturing 4.Ancient China: ?

1) Science: Ancient China's greatest contribution to the world in science was the four major inventions - papermaking, printing, gunpowder, and the compass. The four great inventions not only changed China, but also affected the world

2) Literature: Ancient China has four famous works that should be the first in the world - "Journey to the West", "Water Margin", "Romance of the Three Kingdoms" and "Dream of Red Mansions".3) Medical aspects:

Hua Tuo invented hemp boiling powder, more than 1,000 years earlier than the West, Li Shizhen's "Compendium of Materia Medica" in the Ming Dynasty, and the world's earliest medical college in the Tang Dynasty4) Architecture: The industrious and intelligent ancient Chinese people built the great Great Wall, the Forbidden City, etc.

There is also a monograph on architecture, "Heavenly Creation".5) Agronomy: Jia Sixian's author of "Qi Min Yao Shu", which played a great role in promoting the development of agriculture in ancient China.

The representative inventions of ancient China are the four great inventions.

1. Gunpowder played a huge role in smashing the Western knightly class and establishing a regime belonging to the bourgeoisie;

2. The introduction of papermaking and printing promoted the development of the Western Renaissance and Enlightenment;

3. The guide is decisive for the great geographical discoveries of the 15th century.

4. In addition, such as the contribution of arithmetic and pi to mathematics in nine chapters; Compendium of Materia Medica, Four Diagnoses** for the Perfection of Medicine; The contribution of geokinetic instruments, observations of solar and lunar eclipses to astronomy, and so on. It can be said that ancient Chinese science and technology played a decisive role in the development of science and technology in the early days of the world, and China was the center of science and technology in the ancient world.

Civilization is all the material and spiritual achievements created by mankind. In this sense, the history of civilization is also the general history of the world. In the past, the general history of the world focused on things that were short-lived, political events, great figures, and later added things that were more stable such as the economic situation and cultural situation.

The history of civilization is different from the history of the world, that is, the unit it studies is each civilization, and it is the flow, development, and change of famous civilizations in the long river of history. Not only have some of the original ancient agricultural civilizations developed into industrial civilizations and grown into the current strong civilizations, but with the progress of the economy and the development of industrialization, there will also be the weak civilization of the original Sakura Tan Kailai to grow and become a new important civilization. Therefore, despite the development of globalization, in the foreseeable future, the world will still be a world of diversity and unity, and a world where civilizations coexist.

1. Ancient Egypt: pyramids, sphinxes, sun temples, hieroglyphs, etc.

2. Ancient Bhabi ruined his brothers: the Code of Hammurabi, the Hanging Gardens, cuneiform, etc.

3. Ancient India: Hinduism, Buddhism, surgery, Arabic numerals, caste system, etc.

4. China: sub-feudal system, lunar calendar, oracle bone inscriptions, bronzes, etc.

The four major civilizations actually correspond to the birthplace of the world's four major civilizations, namely the two river basins, the Nile River basin, the Ganges River basin, and the Yellow River basin, which were the earliest regions where the four large human civilizations were born, and the later Aegean civilization was not included. The significance of the four ancient civilizations lies not in the chronological order of the dust and Zen time, but in the fact that they were the birthplaces of many later civilizations and had a great impact on the regions where they were located. The four major civilizations are the original civilizations, while the other civilizations belong to the derivative civilizations and are deeply influenced by the native civilizations of the neighboring regions.

Ancient China: The Four Great Inventions.

Ancient Egypt: Ancient Egypt was very rich in culture. The hieroglyphs created had a great influence on the later Phoenician alphabet, while the Greek alphabet was created on the basis of the Phoenician alphabet.

In addition, the pyramids, the lighthouse of Alexandria, the temple of Amun and other buildings reflect the Egyptians' superb construction technology and mathematical knowledge, and there are also great achievements in geometry, calendar, etc.

The ancient Egyptian civilization is one of the four ancient civilizations. In addition to being famous for building pyramids, sphinxes and mummies, the ancient Egyptians also invented many things that had a profound impact on later generations.

Ancient India: Ancient India is one of the cradles of human civilization and has made contributions to human civilization in literature, philosophy, and natural science.

Contribution of originality. In literature, the immortal epics Mahabharata and Ramayana were created. In philosophy, he founded the "Cause and Clarity", which is equivalent to today's logic.

In the natural sciences, the most outstanding contribution was the invention of the notation method that is currently used in the world, creating 10 numeric symbols, including "0". The so-called Arabic numerals actually originated in India and only spread to the West through the Arabs. In the 6th century B.C., Buddhism also arose in ancient India, and was later introduced to China, Korea, and Japan.

Ancient Babylon: ?

In 4000BC, the Sumers were the first to invent pictographs of ideograms and signifiers, as most of them were carved in brick, stone, or black basalt. Clay tablets,"The pen is heavy and the imprint is deep"It is shaped into a sharp split, resembling a wooden wedge, so it is called cuneiform.
