- Tendril_perversion abstract "Tendril perversion, often referred to in context as simply perversion, is a geometric phenomenon found in helical structures such as plant tendrils, in which a helical structure forms that is divided into two sections of opposite chirality, with a transition between the two in the middle. A similar phenomenon can often be observed in kinked helical cables such as telephone handset cords.The phenomenon was known to Charles Darwin, who wrote in 1865,The name perversion for the transition from one chirality to another was known to James Clerk Maxwell, who attributed it to the topologist J. B. Listing.Tendril perversion can be viewed as an example of spontaneous symmetry breaking in which the strained structure of the tendril adopts a configuration of minimum energy while preserving zero overall twist.[citation needed]Tendril perversion has been studied both experimentally and theoretically. Gerbode et. al. have made experimental studies of the coiling of cucumber tendrils. A detailed study of a simple model of the physics of tendril perversion was made by MacMillen and Goriely in the early 2000s. Liu et al. showed in 2014 that "the transition from a helical to a hemihelical shape, as well as the number of perversions, depends on the height to width ratio of the strip's cross-section."".
