上期我们讲了毕达哥拉斯以及他发现勾股定理的过程.除此之外,毕达哥拉斯还发现并证明了三角形的内角和等于180°,发现了无理数等.但是,我们需要关注的不仅仅是他在数学上的成就,更重要的是他的数学思想,是他“万物皆数”的哲学观点.后面 In the last issue we talked about Pythagoras and his discovery of the Pythagorean Theorem, in addition to which Pythagoras found and proved that the interior angles of the triangles are equal to 180 ° and that they found irrational numbers, etc. However, we need His concern is not only his mathematical achievement, but more importantly, his mathematical thinking is his philosophical point of view.
