笛卡尔,17世纪法国伟大的哲学家、物理学家、数学家、生理学家,一生致力于代数和几何的研究.1637年,在他创立了坐标系后,又成功地创立了解析几何学.今天,我想给大家介绍,笛卡尔当年是如何创立坐标系的.1620年深秋,莱茵河畔的乌尔姆小镇扎下一排军用帐篷,夜很深了,可是帐篷里的一位年轻士兵却翻来覆去怎么也睡不着,他就是后来闻名于世的数学家笛卡尔.这天晚上,在这个陌生的地方,笛卡尔一时难以入睡,他又思考起几何与代数的结合.
Descartes, a great French philosopher, physicist, mathematician, and physiologist of the seventeenth century, devoted his life to the study of algebra and geometry. In 1637, after he founded the coordinate system, he successfully established analytic geometry. Today, I would like to introduce to you how Cartesian created the coordinate system of the year. In the late autumn of 1620, a row of military tents was wedged in the town of Ulm on the Rhine. Night was deep, but a young soldier in the tent But he was later known as the famous mathematician Descartes.At that night, in this strange place, Descartes could hardly sleep for a moment, and he again considered the combination of geometry and algebra.
