Originally published in 1954, as a second edition of a 1947 original, this book explores in depth the rapid research and development of radar technology throughout the Second World War. Notably, the subject matter of radar falls into two distinct categories: the principles of the subject and their application to practical use. The principles are described in the first sixteen chapters of the book, whilst the last three chapters deal with the practical application of radar. The book also presents a description of military radar, the civil uses of radar and the extensive applications of radar technique in the physical sciences. Diagrams and photographs are included for reference. This book will be of great value to scholars of the history of physics.

This book was first published in 1962, at a time when the meteorological study of cloud physics was gaining increasing prominence, largely due to numerous technological advances. Within this volume, Professor N. H. Fletcher introduces the less expert reader to these impressive developments in the study of cloud physics, whilst also constructing an indispensable collection of references for those with a more concentrated interest in the field. Throughout the book, Fletcher's emphasis is on microphysical processes in cloud development and the production of precipitation. He writes engagingly on the dynamics and microphysics of clouds, the microstructure of non-freezing clouds, the processes of ice formation and the artificial modification of clouds, amongst other topics. Accordingly, this book will be of great interest to any modern physicists wishing to glean an idea of how the advanced study of cloud physics was first conducted, and how the first conclusions were drawn.
