The Origin and Principle of the Globe
The globe could be traced back to the ancient Greek period. The Alexandria port geologist Claudius Ptolemaeus (Ptolemy) designed the globe around 150 AD, but this was not the origin of the globe. Before that, people had a basic understanding and exploration of the Earth. The ancient globe was made based on astronomy and geography. It was used to display the basic shape and geographical outline of the Earth, as well as for astrology, religion, and mythology. The first globe of modern significance was invented in 1492 by the German navigator Beheim based on his navigation practice. The globe of the Middle Ages was mainly made in Europe, combining religion and secular regime to reflect the social and political situation at that time. The production materials were generally made of wood or stone, and the production process was rough but rich in content. From the end of the 15th century to the beginning of the 16th century, during the period of geographical discovery, the production of the globe was more accurate and the content was richer. The new discoveries of the explorers provided more information and data, and people had a deeper understanding of the shape and size of the Earth. During the scientific globe era from the end of the 18th century to the beginning of the 19th century, the globe was made using spherical geometry and surveying techniques. It was more precise and had more content. New technology was also introduced. After the 20th century, with the development of computers and digital technology, modern globe had made great breakthroughs in accuracy, content, interaction, and visualization. In terms of the principle of the globe, an ordinary globe rotated around the earth's axis. The two points where the earth's axis intersected with the ball were the poles. The upper pole was the North Pole, and the lower pole was the South Pole. The magnetic levitation globe made use of the magnetic effect of the current to make the globe float in the air. There was a magnet at the top of the globe, and there was a metal coil at the top of the circular plastic frame. The metal coil became an magnet through the current, and the attraction between the magnet and the magnet at the top of the globe could offset the gravity of the globe, thus making the globe float. The negative feedback mechanism could make the globe return to its original position after it deviated from the balance position. At the bottom of the globe, there were also magnets and Hall detectors to maintain balance. Gently rotating the globe would follow the principle of inertia (more specifically, the principle of conservation of momentum) and rotate at a fixed speed in a fixed direction.
Secret scripts about the big stars
In the entertainment industry, because of the special nature of work and the way in which celebrities realized their value, their marriage and other personal matters were often related to their careers, so there would be some special documents. Taking divorce as an example, the divorce document of a celebrity couple not only showed their relationship status, but also the maintenance of their career. For example, Tse Tse and Cecilia Zhang divorced, after dozens of days of cold war before the official announcement of divorce; Li Xiaolu and Jia Nailiang after the "hair" incident, Jia Nailiang maintained the family for many times but finally declared divorce, Li Xiaolu after divorce issued a long article of inner monologue also failed to reverse the decline of her career; Feng Shaofeng and Zhao Liying divorce news detonated the Internet, their divorce document is also a kind of explanation to the outside world; When Faye Wong and Li Yapeng divorced, Li Yapeng's script," You are destined to be a legend," seemed to imply something, while Faye Wong maintained a cold attitude and announced the divorce.
