欧几里得是古希腊数学家,以其所著的《几何原本》闻名于世。他将公元前7世纪以来希腊几何积累起来的丰富成果整理在严密的逻辑系统之中,使几何成为一门独立的、演绎的学科。《几何原本》的重要性并不在于书中提出的哪一条定理,欧几里得的伟大贡献在于他将这些材料做了整理,并在书中作了全面的系统阐述。《几何原本》基 Euclid is an ancient Greek mathematician famous for his “geometric origin.” He organized the richness of the Greek geometry accumulated in the seventh century bc into a rigorous logical system, making geometry an independent and deductive subject.
