Globe, the model of the Earth. A globe is a model globe of the earth made in imitation of the shape of the earth, reduced to a certain scale, in order to facilitate the understanding of the earth.
The globe is provided with lengths, areas, and distortions of direction and shape so that the interrelationship of the various sights observed from the globe is integral and approximately correct.
In 1492, the year Christopher Columbus crossed the Atlantic, Martin Behaim completed a 20-inch diameter globe at Nuremberg. Because the globe was based on the map in Ptolemy's Geographical Guide, Behaim's depiction of Asia was much longer to the east than it actually was, and so the Atlantic Ocean was much narrower than it actually was. The number of errors is staggering.
Interestingly, however, the globes he drew on the eve of the discovery of North America provided some useful ideas about geography for the people of the time. The early globes were made by printing narrow triangular blocks, which were then cut out and glued to a wooden ball.
The most famous German globe maker was the Nuremberg scholar Joanhans Schoner. The two globes he made in the early 16th century have survived to this day.
By product material and function there are paper globes, plastic globes, resin globes, stone globes, solid wood globes, metal globes, solid wood globes, magnetically levitated globes, classically crafted globes, electronic point-and-speech globes, audio globes, video globes, etc.
Those who have seen a globe will have a question, why is the globe tilted?
The Earth's position in space would not be straight up and down because there is an angle of 23°26' between the plane of the ecliptic and the equatorial plane, which is also called the angle of the ecliptic.
The globe was designed to be more accurate for people to understand the Earth and was deliberately designed to be tilted so as to be more in line with the laws of science.
The ecliptic angle is the angle of intersection between the Earth's orbital plane (the ecliptic plane) and the equatorial plane (the celestial equatorial plane). The ecliptic angle of the Earth is approximately 23°26'.
The ecliptic angle is not constant, it varies slightly all the time, but the variations are so small that they are negligible for short periods of time.
The existence of the ecliptic angle is of great astronomical and geographical importance, as it is one of the causes of the movement of the Earth's axis, and is also the main reason for the annual variation in the length of the apparent solar day, as well as the fundamental reason for the change of the seasons and the distinction between the five zones on Earth.
