Collected in this second volume are many of Richardson's papers covering the behavioural sciences.Throughout his life Lewis Fry Richardson made many inspirational contributions to various disciplines. He is best known for his wealth of important work on meteorology, and his ground-breaking application of mathematics to the causes of war. His field of interest was in no way limited to these and various aspects of psychology and mathematical approximation also benefited from his unique approach.

Collected in this second volume are many of Richardson's papers covering the behavioural sciences.Throughout his life Lewis Fry Richardson made many inspirational contributions to various disciplines. Often his ideas were ahead of contemporary thinking, and preceded the technical means necessary for their practical implementation. He is best known for his wealth of important work on meteorology, and his groundbreaking application of mathematics to the causes of war, though his field of interest was in no way limited to these topics, and various aspects of psychology and mathematical approximation also benefited from his unique approach. The originality of Richardson's research can be seen in this collection of all his important papers in the behavioural sciences.Foreword C. A. B.
