This book describes the process of predicting the weather using numerical calculations by hand instead of on the computer. It was the first weather prediction method published, most likely.
Lewis Fry Richardson, was an English mathematician, physicist, meteorologist, psychologist and pacifist who pioneered modern mathematical techniques of weather forecasting, and the application of similar techniques to studying the causes of wars and how to prevent them. At age 47 he received a doctorate in mathematical psychology from the University of London.
He is also noted for his pioneering work concerning fractals and a method for solving a system of linear equations known as modified Richardson iteration.[2]
