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.
Famous quotes containing the words physics, blown, sand and/or desert:
“The pace of science forces the pace of technique. Theoretical physics forces atomic energy on us; the successful production of the fission bomb forces upon us the manufacture of the hydrogen bomb. We do not choose our problems, we do not choose our products; we are pushed, we are forced—by what? By a system which has no purpose and goal transcending it, and which makes man its appendix.”
—Erich Fromm (1900–1980)
“Hast ever ben in Omaha
Where rolls the dark Missouri down,
Where four strong horses scarce can draw
An empty wagon through the town?
Where sand is blown from every mound
To fill your eyes and ears and throat;
Where all the steamboats are aground,
And all the houses are afloat?...
If not, take heed to what I say,
You’ll find it just as I have found it;
And if it lies upon your way
For God’s sake, reader, go around it!”
—For the State of Nebraska, U.S. public relief program (1935-1943)
“No more sand art, no sand book, no masters.”
—Paul Celan [Paul Antschel] (1920–1970)
“The change of Philomel, by the barbarous king
So rudely forced; yet there the nightingale
Filled all the desert with inviolable voice
And still she cried, and still the world pursues,
“Jug Jug” to dirty ears.”
—T.S. (Thomas Stearns)
