*1926 Adams-Moulton method.

* 1927 – [[Douglas Hartree]] creates what is later known as the [[Hartree–Fock method]], the first [[ab initio quantum chemistry methods]]. However, manual solutions of the Hartree–Fock equations for a medium-sized atom were laborious and small molecules required computational resources far beyond what was available before 1950.

* 1928 – [[Leslie Comrie]] proposes using commercial [[tabulating machinesmachine]]s to perform scientific calculations, and himself uses them to expand [[Ernest William Brown]]'s lunar calculations.
