Calligraphy and writing are inseparable. Oracle Bone Inscriptions, Zhong Dingwen, Xiao Zhuan, Li Shu, cursive script, running script and regular script are all calligraphy forms based on characters. From the initial graphic characters, to the unified, vertical and horizontal, standardized and orderly seal script, to today's simplified characters, the evolution of characters is actually a history of calligraphy evolution.

Mathematics and calligraphy seem to have nothing to do, but careful observation shows that there is a lot of mathematical knowledge hidden in calligraphy, and when a teacher writes a beautiful, powerful and neat blackboard, it is intended to guide students to use neat handwriting in math homework. A neat and beautiful answer sheet can not only win the favor of the marking teacher, but also make students fall in love with mathematics because they worship the teacher.

1. Parallel, vertical and equidistant are mathematical relations, which embody the writing skills of Chinese characters.

Let students pay attention to fairness first, then pursue danger, and finally return to fairness when practicing calligraphy. By using mathematical relations, parallel horizontal lines can be appropriately changed, and the verticality of vertical painting can make the center of gravity of words stable and powerful. When learning classic works, we can improve our eyesight, learn the correct methods and appreciate them, so that we can learn calligraphy correctly. The center line is determined by mathematical analysis. It is understood that most horizontal paintings of regular script are equally divided by the center line. I see the symmetry of running script, which is more equal division of strength than equal division of the same stroke.

Second, angle, turning point and proportion are mathematical relations, which reflect the style characteristics of fonts.

For example, Zhang Qianbei in Han Li is a vibrant Gu Zhuo. Through observation, the bottom line of this tablet is not straight, but has a certain inclination, about 5, which is a balanced and stable Gu Zhuo flavor and makes the font more natural.

The most distinctive font between Li Kai and Li Kai-"Xianbao Zibei", the turning angle of the font is basically a right angle, vigorous and natural, dignified and elegant, yet naive. We will find that the turning point is more than 90 words, which looks vigorous and powerful, Gu Zhuo; If the turning point is less than 90, men are strong and healthy. The turning angle is exactly 90, dignified, elegant and dignified.

In Han Li, the word "and" is the same. The ratio of Zhang Qianbei is 2\3 and 1\3, and Cao Quanbei basically accounts for 1\2. Therefore, the overall style of "Zhang Qianbei" is wide at the top and wide at the bottom, short at the bottom and dense at the bottom, and heavy at the top, which is a kind of naive beauty. "Cao Quanbei" has longer legs, prominent main pen and more graceful and euphemistic overall style.

Thirdly, straight line, arc and axis are mathematical relations, which reflect the potential relationship of characters in calligraphy.

Because of the center line and geometric structure of regular script, we can easily find the equilateral triangle structure of a word, and the geometric structure of running script has changed more, but the principle of geometric structure remains unchanged. If we can't master the geometric structure in calligraphy, we can't really appreciate calligraphy.

Skimming, pressing and pointing reflect the radian and radian of mathematics, and the lines of many strokes in calligraphy are curved. If mathematical arcs and radians are introduced for analysis, it will be helpful for beginners.

Geometric angle analysis shows that the greater the radian, the greater the line bending degree, and the smaller the radian, the smaller the line bending degree. Oblique skimming, straight skimming and arc skimming can be analyzed as follows: Oblique skimming lines are straight and handsome, and the radian is very small, such as the first stroke of Yi; The brushstroke is straight and sharp, without radian, such as "Nai", and the arc turns round and lustrous, with a large radian.

Calligraphy and mathematics * * * exist, rigorous and lofty sentiments Qi Fei. There is no end to learning. As a math teacher,
