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:
“But this invites the occult mind,
Cancels our physics with a sneer,
And spatters all we knew of denouement
Across the expedient and wicked stones.”
—Karl Shapiro (b. 1913)
“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)
“Change begets change. Nothing propagates so fast. If a man habituated to a narrow circle of cares and pleasures, out of which he seldom travels, step beyond it, though for never so brief a space, his departure from the monotonous scene on which he has been an actor of importance would seem to be the signal for instant confusion.... The mine which Time has slowly dug beneath familiar objects is sprung in an instant; and what was rock before, becomes but sand and dust.”
—Charles Dickens (1812–1870)
“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)
