Chapter 8 second shape

Humans had rudimentary mathematical knowledge before inventing vehicles, using metals, or creating words.Prehistoric artefacts show early human counting with the help of notches on counting sticks.For example: on a 30,000-year-old wolf bone unearthed in Czechoslovakia, there are 55 deep inscriptions, and 5 inscriptions form a group.As early as the ancient culture period of Egypt and Mesopotamia, people knew geometry and arithmetic, although the existing cultural relics and historical materials are very incomplete, which is not enough to explain the degree of people's mastery of this knowledge at that time.Aristotle believed that Egyptian monks developed geometry by devoting their spare time to study.But the Greek historian Herodotus believed that the development of geometry in Egypt was entirely out of necessity.The annual flooding of the Nile submerges large tracts of farmland along the river basin, washing away farmland landmarks.The Egyptians remeasured their land every year, requiring knowledge of angles, directions, and lengths.Undoubtedly, knowledge of geometry was also required to build the Great Pyramids of Egypt.

Most ancient and primitive cultures show that people seemed to have an understanding of geometric shapes at that time.Of course, it is possible that humans are born with a complete concept of graphics.Even the "man who mistook his wife for a hat"—a musician Oliver Sachs, who was mentally ill and unable to recognize people and objects—could recognize geometric shapes.Geometry, as a discipline of mathematics, still retains its vitality today, and geometers still make discoveries in the simplest geometric figures.
