  We consider the problem of two-point resistance on an m x n cobweb network
with a superconducting boundary, which is topologically equivalent to a
geographic globe. We deduce a concise formula for the resistance between any
two nodes on the globe using a method of direct summation pioneered by one of
us [Z. Z. Tan, et al, J. Phys. A 46, 195202 (2013)]. This method contrasts the
Laplacian matrix approach which is difficult to apply to the geometry of a
globe. Our analysis gives the result directly as a single summation.
