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.

“The night has been unruly. Where we lay,
Our chimneys were blown down, and, as they say,
Lamentings heard i’ th’ air, strange screams of death,
And prophesying with accents terrible
Of dire combustion and confused events,
New-hatched to the woeful time.”
—William Shakespeare (1564–1616)
“But the twelve lie in the sand by the dry rock
Seeing nothing—the sand, the tree, rocks
Without number—and turn away the face
To the mind’s briefer and more desert place.”
—Allen Tate (1899–1979)
“Is there any religion but this, to know, that, wherever in the wide desert of being, the holy sentiment we cherish has opened into a flower, it blooms for me? If none sees it, I see it; I am aware, if I alone, of the greatness of the fact. Whilst it blooms, I will keep sabbath or holy time, and suspend my gloom, and my folly and jokes.”
—Ralph Waldo Emerson (1803–1882)
