A rolling ruler is a ruler that contains a cylinder much like a rolling pin inside, thereby enabling it to "roll" along a sheet of paper or other surface where it is being used. A rolling ruler can draw straight, parallel lines, and also has other instruments included, enabling it to do the jobs of a protractor and compass.
Famous quotes containing the words rolling and/or ruler:
“Look, we’re all the same; a man is a fourteen-room house—in the bedroom he’s asleep with his intelligent wife, in the living-room he’s rolling around with some bareass girl, in the library he’s paying his taxes, in the yard he’s raising tomatoes, and in the cellar he’s making a bomb to blow it all up.”
—Arthur Miller (b. 1915)
“Despots play their part in the works of thinkers. Fettered words are terrible words. The writer doubles and trebles the power of his writing when a ruler imposes silence on the people. Something emerges from that enforced silence, a mysterious fullness which filters through and becomes steely in the thought. Repression in history leads to conciseness in the historian, and the rocklike hardness of much celebrated prose is due to the tempering of the tyrant.”
—Victor Hugo (1802–1885)
