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 hardly to be believed how spiritual reflections when mixed with a little physics can hold people’s attention and give them a livelier idea of God than do the often ill-applied examples of his wrath.”

“It is only when we speak what is right that we stand a chance at night of being blown to bits in our homes. Can we call this a free country, when I am afraid to go to sleep in my own home in Mississippi?... I might not live two hours after I get back home, but I want to be a part of setting the Negro free in Mississippi.”
—Fannie Lou Hamer (1917–1977)
“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)
“What e’er you are
That in this desert inaccessible,
Under the shade of melancholy boughs,
Lose and neglect the creeping hours of time.”
—William Shakespeare (1564–1616)
