美国华盛顿大学的一个研究团队最近发现了一种新的不规则五边形(图1),相互组合后可完全铺满平面。不会出现重叠或空隙.这是第15种能做到此效果的五边形,距上次发现有类似效果的五边形已时隔30年!这项发现相当于在数学领域中寻获了新的原子粒子.该 A research team at Washington University in the United States recently discovered a new irregular pentagon (Figure 1) that, when combined with each other, completely covers the plane. No overlap or void. This is the 15th pentagon that can do this, 30 years after the last discovery of a pentagonal effect! This finding is equivalent to finding in mathematics The new atomic particles
