摆线
在数学中，摆线（Cycloid）被定义为，一个圆沿一条直线运动时，圆边界上一定点所形成的轨迹。它是roulette曲线的一个例子。
摆线也是最速降线问题和等时降落问题的解。
摆线的研究最初开始于Nicholas of Cusa，之后梅森（Marin Mersenne）也有针对摆线的研究。1599年伽利略为摆线命名。1634年G.P. de Roberval指出摆线下方的面积是生成它的圆面积的三倍。1658年克里斯多佛·雷恩也向人们指出摆线的长度是生成它的圆直径的四倍。在这一时期，伴随着许多发现，也出现了众多有关发现权的争议，甚至抹杀他人工作的现象，而因此摆线也被人们称作“几何学中的海伦”（The Helen of Geometers）。.
英语百科
Cycloid 摆线
A cycloid is the curve traced by a point on the rim of a circular wheel as the wheel rolls along a straight line without slippage. It is an example of a roulette, a curve generated by a curve rolling on another curve.
The inverted cycloid (a cycloid rotated through 180°) is the solution to the brachistochrone problem (i.e., it is the curve of fastest descent under gravity) and the related tautochrone problem (i.e., the period of an object in descent without friction inside this curve does not depend on the object's starting position).
