Comments The persistence length is a basic mechanical property quantifying the stiffness of a long polymer. Formally, the persistence length, P, is defined as the length over which correlations in the direction of the tangent are lost. Alternatively, The idea of the persistence length is that it defines the scale over which a polymer remains roughly unbent in solution. A piece of cooked spaghetti has a persistence length on the order of 1.5 cm (Wikipedia). See BNID 103113, 106650
