Van Allen Belts

Famous quotes containing the words van and/or belts:

“To call a posit a posit is not to patronize it. A posit can be unavoidable except at the cost of other no less artificial expedients. Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built.”
—Willard Van Orman Quine (b. 1908)

“Such a style,—so diversified and variegated! It is like the face of a country; it is like a New England landscape, with farmhouses and villages, and cultivated spots, and belts of forests and blueberry swamps round about, with the fragrance of shad-blossoms and violets on certain winds.”
—Henry David Thoreau (1817–1862)
