Computer science

• April - Leslie Comrie publishes an article "On the Construction of Tables by Interpolation", describing the use of punched card equipment for interpolating tables of data, and becomes the first to use such equipment for scientific calculations, using Fourier synthesis to compute the principal terms in the motion of the Moon for 1935–2000.

History of science
