The Physics of Blown Sand and Desert Dunes (1941) is a science book, written by Ralph A. Bagnold. The book laid the foundations of the scientific investigation of the transport of sand by wind. It also discusses the formation and movement of sand dunes in the Libyan Desert. During his expeditions into the Libyan Desert, Bagnold had been fascinated by the shapes of the sand dunes, and after returning to England he built a wind tunnel and conducted the experiments which are the basis of the book. The book is still a main reference in the field, and was, for instance, used by NASA for studying sand dunes on Mars. It was recently reissued by Dover.

“... it is as true in morals as in physics that all force is imperishable; therefore the consequences of a human action never cease.”

Like dust blown through the streets of Rome,
Change ever, too; we have no home,”

“The shore is composed of a belt of smooth rounded white stones like paving-stones, excepting one or two short sand beaches, and is so steep that in many places a single leap will carry you into water over your head; and were it not for its remarkable transparency, that would be the last to be seen of its bottom till it rose on the opposite side. Some think it is bottomless.”
—Henry David Thoreau (1817–1862)
“The desert is not only around the corner,
The desert is squeezed in the tube-train next to you,
The desert is in the heart of your brother.”
—T.S. (Thomas Stearns)
