Famous quotes containing the words rigid and/or panels:
“Lets call something a rigid designator if in every possible world it designates the same object, a non-rigid or accidental designator if that is not the case. Of course we dont require that the objects exist in all possible worlds.... When we think of a property as essential to an object we usually mean that it is true of that object in any case where it would have existed. A rigid designator of a necessary existent can be called strongly rigid.”
—Saul Kripke (b. 1940)
“He sent for lancewood to make the thills;
The crossbars were ash, from the straightest trees;
The panels of white-wood, that cuts like cheese,
But lasts like iron for things like these;
The hubs of logs from the Settlers ellum,
Last of its timber,they couldnt sell em,”
—Oliver Wendell Holmes, Sr. (18091894)
