(13213) Maclaurin Main-belt Asteroid
Discovered on 3 May 1997 by E. W. Elst at La Silla.
Scottish mathematician Colin Maclaurin (1698–1746) is known for his “Taylor adapted series”, which he used for adding powers of arithmetic progressions. He is particularly honored for his Treatise of Fluxions (1742), in which he presented for the first time Newton's methods on this subject.Naming citation (WGSBN Bull. 4, #12, 5), IAU / Minor Planet Center, via NASA/JPL
