阅读全文原文作者：Cynthia J. O. Reichhardt & Charles Reichhardt 一些非平衡系统中的相变不能用经典的统计力学定律描述。而现在，一个涉及奇异点的数学方法解决了这个具有重要影响的问题。 根据牛顿第三定律，所有的相互作...
阅读全文机器之心报道 编辑：杜伟、陈萍 本想着或许可以取得一些不错的进展，没想到取得了意料之外的收获。 等角线（Equiangular Lane）是一个数学用语，通常在数学上这样表示：在ABC 中，在线段 BC 上取 P、Q，使得∠BAP=∠...
阅读全文等角线是空间中相交于同一个点的一组直线，而这些直线中两两形成的夹角都相等。 在二维平面中，正六边形的三条对角线就是一组等角线，任意两条线形成的夹角都是60°。同时，这种情况也是二维中等角线数量的极限，换句...
阅读全文新智元报道 来源：MIT 编辑：LRS 【新智元导读】解决一个七十年悬而未决的问题需要多久？答案显然不是七十年。最近MIT著名华人数学副教授Yufei Zhao带领两名本科生只用了一个暑假就完全攻克图论中的等角线问题，为后...
