The growth of computational facilities in the period since World War I has already been phenomenal, and the possibilities in the near future are beyond imagining. The number of excellent calculating machines now available in almost every office or laboratory, to say nothing of the amazing Sequence Controlled Calculator, or the equally marvelous Electronic Numerical Integrator and Calculator, makes it possible to solve whole categories of problems that only yesterday were prohibitively difficult. In consequence the subject of numerical analysis is surely destined to make enormous strides in the decades to come.
