The curve on the Mercator map (x,y) is given by the functions x(φ) = R φ, y(φ) = R sin(φ + a)/√[b² + sin²(φ + a)], where 0<φ<2π is "longitude", R is the radius of Earth and a, b are parameters depending on the great circle (e.g. b→∞ yields the Equator).pic.twitter.com/SUeMQTlkkq

在黎曼球面几何学中,这一个赤道大圆,把一个双叶球面的地球,分割为两个独立的单叶半球面。而在欧几里德平面几何学中,即在这个墨卡托圆柱投影几何学中,这一个赤道直线,把一个双叶圆柱面的地球,分割为两个独立的单叶半平面面。在泛函拓扑几何学中,一个双叶球面,先变形为一个双叶圆柱面,

再变形为一个双叶平面。从而使得双叶二维球面上的国际空间站围绕地球340公里高的周围有圆形的轨迹,在双叶2维墨卡托平面上,变形为一根正弦曲线形的轨迹。换言之,在泛函拓扑几何学中,同一条曲线,在黎曼球面几何学中,在墨卡托圆柱投影几何学中,在欧几里德平面几何学中,分别有三种不同形状的曲线。
