In a paper on Large-scale Electronic Digital Computing Machines read before the Institute in 1953 (J.I.A. 79, 274) R. L. Michaelson drew the attention of actuaries to the possibilities which existed in a life office for the use of a large-scale electronic digital computer (referred to hereafter as a ‘computer’). Both the paper itself and the discussion which followed emphasized the need for a detailed investigation of the problems involved from the points of view of the life office and the manufacturer.2. The author of this paper has been privileged to undertake, in close cooperation with a large manufacturer of computers in this country, a detailed investigation of possible life-office organization based on a computer. This paper sets down some of the results of this investigation with particular reference to life offices transacting ordinary as distinct from industrial life assurance.

Charge Independence

The low energy properties of two-nucleon potentials with infinite repulsive cores have been studied by numerical calculations using an electronic digital computer. The consequences of assuming charge independence for the nuclear force in the 1S state have been examined by performing computations with several potential shapes for both the neutron–proton and proton–proton systems. It was found that this assumption severely restricts the possible potential shape. Charge independence occurs with the Yukawa potential for zero core radius. Potentials that are more singular at small distances than the Yukawa require larger core radii; less singular potentials are not charge independent.

SummaryA method is given for the solution of the flutter determinant on a general purpose electronic digital computer. The method has been programmed for the N.R.D.C. 401 Computer and details of this programme are given. A quicker programme, applicable when only structural damping is present and there are two degrees of freedom, is also discussed. Appendix I discusses in detail the types of errors which occur when the method is applied and Appendix II considers the anticipated loss of accuracy which will be encountered when using the method in cases where the number of degrees of fredom is large.
