Literary notes about elastic (AI summary)
The use of "elastic" in literature spans both concrete and abstract applications. Authors invoke the term to describe physical properties—such as the resilient walls of arteries that maintain form even when empty ([1]) or the adaptable nature of elastic fluids in scientific expositions ([2])—while simultaneously employing it to convey dynamic movement and the flexible qualities of human spirit. For instance, characters may be depicted with an "elastic step" that suggests buoyancy and energy in their actions ([3], [4]), or the metaphor extends to illustrate an unyielding inner resolve ([5]). This broad deployment of "elastic" enriches descriptions by linking tangible physical flexibility with metaphorical endurance and adaptability.
