Digital currency Plato
2. Bitcoin was born in 2008 and has been known for more than 10 years; Gold originated from the feudal dynasty, with a history of thousands of years and a strong consensus
3. There are only 21 million bitcoins. The total amount of bitcoins is constant and will never be issued again. The mining cycle is halved every four years, which is deflationary; Gold needs physical mining, and the total amount of gold will change with the continuous mining
4. Bitcoin has the value of saving, and gold has the value of collecting
5. Bitcoin is divisible. One bitcoin can be divided into innumerable parts, up to 8 decimal places; Gold can not be subdivided, and the cost of segmentation is high and inconvenient
6. Bitcoin is more convenient to save assets. As long as you keep your private key, you can keep your wealth in your hands all the time; Gold cannot be stored in large quantities and needs to be stored in third-party institutions. It is clear how many asset centralization institutions there are.
Athens, with a history of more than 5000 years, is rich in historical sites. Ancient Athens is the source of western culture. Athenians made outstanding contributions to art, philosophy, law and science. It is said that Athens was named after Athena, the goddess of wisdom in the legendary historical story. The northeast part of the whole urban area is the political and cultural area, and the southwest and port area is the instrial and commercial area. Athens is located in the shipping and aviation center of the eastern Mediterranean countries. Piraeus, a seagoing vessel in the outer port, has been converging, and almost all foreign trade is going in and out here. The city's drinking water is supplied by the marathon reservoir far from the northeast, where there is a marble dam rarely seen in the world. Athens is the ancient cultural center of Greece. Many ancient cultural sites are still preserved, and its museums are well-known in the world. Athens is one of the oldest cities in Europe and even the whole world. Its history can be traced back to more than 3000 years ago. In 1000 BC, Athens became the core city of ancient Greece. From the late 9th century B.C. to the early 8th century B.C., Athens had luxury tombs of nobles, and the proction of iron and bronze also developed rapidly, reaching the level of establishing a city-state, an early slave state. Solon was the first consul of the city-state of Athens, and Pisistratus was his successor. During the period of their control, the instry and Commerce in Athens developed significantly. It became the cradle of western culture in the 5th century BC< In 492 BC, the war between Greece and Poland broke out, and Persia was defeated in several major battles. It was not until 449 BC when the two sides concluded a peace treaty that the war ended. In June 431 BC, the Peloponnesian War between Athens and Sparta broke out, which lasted more than 20 years and ended in Athens' failure<
Athens began to decline in the middle ages and recovered ring the Byzantine Empire. During the Jihad, Athens prospered because of its trade with Italy. During the reign of the Ottoman Empire, Athens declined again. In the 19th century, Athens became the capital of independent Greece. In 1920s, e to the outbreak of the war, a large number of refugees from Anatolia, Turkey, poured into Athens, which also expanded the population of Athens. Today about half of the Greek population lives in Athens.
the following is a friendly tip from a bank. First, the manufacturing process is poor, the nickel coating is thin, and it is easy to rust and rot. Real coins are generally not rusty. If rusty coins are found, they are likely to be counterfeit coins< Second, the grain of wheat ear in the national emblem is fuzzy, the ribbon level is poor, and the fine stripe is not clear
Third, the five pointed star in the national emblem has poor three-dimensional sense, the angle of the five pointed star is long and short, and the top is smooth
4. The strokes of Chinese characters and Pinyin letters on the front are thick, the petals and veins of chrysanthemum on the back are fuzzy, and the flower core is fuzzy
fifthly, fake coins are lighter than real coins.
It was invented by Indians
around 500 BC, with the rise and development of economy and Brahman culture, mathematics in Punjab, northwest of the Indian subcontinent, has been in a leading position. The astronomer abelhait has made a new breakthrough in simplifying numbers. He records the numbers in one lattice. If there is a symbol in the first lattice, such as a dot representing 1, then the same dot in the second lattice represents 10, and the dot in the third lattice represents 100
In this way, not only the number symbols themselves, but also the order in which they are located, also have important significance, that is to say, Indians are the inventors of Arabic numerals 
extended data:
Evolution
around 2500 B.C., a kind of inscriptions counting method called Halaba number appeared in ancient India. By about A.D., there were two kinds of numbers: karoshki number and Brahman number. In the third century, the Indian scientist Bagdad invented the Arabic numerals. After the 4th century, the sign of zero in Arabic numerals became more and more clear, which graally developed the decimal value system. For example, the devonagli number appeared after the 8th century
In the 9th century, Indian numerals were introced into the Arab region, and two kinds of Arabic numerals were derived from the original Brahman numerals: the eastern Arabic numerals used by the Arabs in the Middle East and the Western Arabic numerals used by the Arabs in Spain. The eastern Arabic numeral is very similar to the form used by Arabs, and the Western Arabic numeral later developed into the form widely used by usArabic numerals are simple in strokes, convenient in writing, and easy to calculate by using decimal system, which has graally become popular in various countries and become a common number in the world
The positions of Arabic numerals in Unicode code are 048 to 0572. Did the imperial examination system restrain the development of science and technology
3. What is Needham's dilemma
- - -
3 should be the first one
1 farming economy is characterized by self-sufficiency, which only needs a small amount of exchange of necessities of life, so it can not form a unified market, hindering the exchange between various places, so it can not proce the exchange of modern science and technology. Moreover, the agricultural economy can not accumulate a lot of surplus wealth, resulting in insufficient social funds for scientific research
2 the imperial examination system consolidated the agricultural economic and social system for the same reason as 1. Second, it attracted the most outstanding talents to the imperial examination Road, which made no one concerned with other practical knowledge, hindered the development of practical science, and therefore restrained the development of modern science and technology
3 Needham's problem is that ancient China had great achievements in science and technology. Why was it surpassed by the West in modern science. In fact, many people don't think that Needham's problem is a problem, and I think so, because its precondition is not tenable. In fact, most of the rich scientific achievements in ancient China are practical technology and lack of scientific spirit. Therefore, after the whole society paid less attention to practicality and more attention to ethics, practical technology is still developing slowly, but western science is developing rapidly,

1. Advantaged River Civilization: four ancient civilization countries
common reasons for the emergence of ancient civilization countries
the Nile Valley of ancient Egypt originated from the river about 3000 BC, and benefited from the feeding of the river. The river has abundant irrigation water resources, rich water resources and flat terrain, The land is relatively fertile; The climate is mild, suitable for human survival, concive to crop cultivation and growth, can meet the basic needs of people's survival, it can be seen that early human dependence on the natural environment is strong< In ancient China, the Yangtze River and the Yellow River were founded in 2070 BC by Yu. 2. The formation of the early state. The emergence of the ancient civilization, the city, the royal power, the sacred social rank, the army and the punishment. 3.

1. Greek civilization
Aegean civilization --- 2000-1200 BC, with Crete and Mycenae as the center, the Aegean civilization was formed, Greece entered the city-state era, with Athens and Sparta as important representatives< The reason for this difference is determined by the specific situation of the city-state.
