DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OSGA/91/">A 
 Central Result from Newton's Principia Mathematica: The Body of Least Resi
 stance</a>\nby Josef Bemelmans (RWTH Aachen University) as part of Online 
 Seminar "Geometric Analysis"\n\n\nAbstract\nIn Newton's Principia Mathemat
 ica fundamental theorems\, e.g about the motion of planets around the sun\
 , are proven by methods of ancient geometry rather than infinitesimal anal
 ysis\, as one might expect. There are however problems in the Principia th
 at are treated using techniques from calculus\; we present one that in tod
 ay's terminology belongs to the calculus of variations: to determine the s
 hape of a rotationally symmetric body of prescribed base and height such t
 hat its resistance in a uniform fluid flow becomes minimal.\n
