The seemingly abstract geometry can actually be seen everywhere in our lives. Grandpa, who has been a math teacher for 40 years, tells vivid and interesting geometric stories and takes you into the wonderful geometric world.
You will be surprised to find that there are countless symmetry axes hidden in pizza, houses on the roadside can not be separated from triangles, and the hexagonal beehives of bees are carefully designed ... Geometry is not just a boring theorem in books, whether it is flat or three-dimensional. Open your eyes to be a geometry detective and discover the mystery behind everyday things.
Geometry is the study of spatial structure and properties. It is one of the most basic research contents in mathematics, which has the same important position as analysis and algebra, and has a very close relationship. Geometry has a long history and rich contents. It is closely related to algebra, analysis and number theory.
Geometric thought is the most important thought in mathematics. The temporary development of each branch of mathematics tends to geometry, that is, to explore various mathematical theories with geometric viewpoints and thinking methods. Common theorems are Pythagorean Theorem, euler theorem Theorem and Stewart Theorem.
Basic meaning
Geometry is the study of spatial structure and properties. It is one of the most basic research contents in mathematics, which has the same important position as analysis and algebra, and has a very close relationship.
The origin of the name
The word geometry comes from the Greek word "γ ε ω μ ε ρ? Alpha ",by" γ? α "(land) and μ ε ρ ρ ε? ν "(measurement) is a combination of two words, which refers to the measurement of land, that is, geodesy. Later it was translated into Latin "geometria". The Chinese word "geometry" was coined by Xu Guangqi when Matteo Ricci and Xu Guangqi jointly translated The Elements of Geometry in the Ming Dynasty.
No basis was given at that time. Later generations think that, on the one hand, geometry may be transliteration of the Latin Greek GEO; on the other hand, because geometry originally used geometria to explain the content of number theory, it may also be a free translation of quantity (quantity), so it is generally considered that geometry is a simultaneous translation of sound and meaning.
