DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Geometry/34/
 ">Shortest closed curve to inspect a sphere</a>\nby Mohammad Ghomi (Georgi
 a Institute of Technology) as part of Pangolin seminar\n\n\nAbstract\nWe s
 how that in Euclidean 3-space any closed curve  which lies outside the uni
 t sphere and contains the sphere within its convex hull has length at leas
 t 4Pi. Equality holds only when the curve is composed of 4 semicircles of 
 length Pi\, arranged in the shape of a baseball seam\, as conjectured by V
 . A. Zalgaller in 1996. This is joint work with James Wenk.\n
