In 1943 - 1945, he worked in the Institute for Advanced Study at Princeton. Having arrived in the United States for two months, he finished his famous paper entitled "A simple intrinsic proof of the Gauss-Bonnet formula for closed Riemannian manifolds", which inspired other differential geometers.

抵美两个月后，即完成其著名的论文──《闭曲面流形高斯--博内公式(Gauss-Bonnet Formula)的一个简单的内蕴证明》，对於后来微分几何的发展和微分几何学者的研究影响深远。

The theorems of Ibn al-Haytham, Omar Khayyam and Nasir al-Din al-Tusi on quadrilaterals , including the Lambert quadrilateral and Saccheri quadrilateral , were the first theorems on elliptical geometry and hyperbolic geometry , and along with their alternative postulates, such as Playfair's axiom , these works had a considerable influence on the development of non-Euclidean geometry among later European geometers, including Witelo , Levi ben Gerson , Alfonso , John Wallis , and Giovanni Girolamo Saccheri .

定理伊本Haytham，欧玛尔海亚姆和纳西尔基地丁铝土司上quadrilaterals ，包括德兰伯特四边形和萨凯里四边形，是第一个椭圆形的几何定理和双曲几何，并连同其替代假设，如普莱费尔的公理，这些作品有相当发展的影响非欧几里德几何之间稍后欧洲geometers ，包括Witelo ，列维本格森，阿方索，约翰瓦利斯和乔瓦吉罗拉莫萨凯里。

The upshot of the controversy is that the pure geometers reasserted their role in mathematics.

论战的结局是纯粹几何学家重申了他们在数学中的作用。

Ever since Plato, philosophers have envied geometers their certitudes. So it's not surprising that the story about philosophy being conceptual analysis was well received all the way from Oxford to Berkeley, with many intermediate stops.

自柏拉图以来，哲学家们就在嫉妒几何学家所拥有的确信无疑，所以，&哲学即概念分析&这一信条，从牛津到伯克利，一路凯旋而至，就丝毫不足为奇了。

Some of the seventeenth -century geometers undertook to answer these questions.

十七世纪的一些几何学者就开始寻找这些问题的答案。

The rivalry between analysts and geometers grew very bitter.

分析学家与几何学家之间的对抗非常激烈。

But our intrepid geometers found that by using equilateral triangles rather than squares, they could generate a savings of 0.1 percent.

但我们坚韧不拔的几何学家们发现，如果用等边三角形而非正方形的话，可以省下0.1%的包装材料。

Meanwhile, much of the software, such as Flash, PowerPoint, and so, is not quite fit for practical teaching, partly because such software is difficult to use or doesn't prove highly effective, which, to some extent, has restricted the development of the Application of Geometers sketchpad to helping to physics teaching.

但是，许多软件（比如flash、PowerPoint等）由于使用难度及使用效果等方面的欠缺，并不适用于教学实际的需要，这在某种程度上制约了计算机辅助物理教学的快速发展。

This article first explains the content and the theoretical basis of the Geometers Sketchpad and the integration of geometry teaching, and then analyzed the feasibility and the advantages of the Geometers Sketchpad integrating with teaching, and then put forward what principles and measures should be noted in the integration of teaching, and finally gave some specific cases.

本文首先针对几何画板与平面几何整合教学的内涵和理论基础进行分析，接着分析了几何画板整合教学的可行性及其优势，然后针对整合教学提出应注意的原则及措施，最后对整合教学给出了具体案例。
