The term "convex" appears across a broad spectrum of literary and academic contexts, often to convey an outwardly curved or bulging shape. In natural history and exploration narratives—most notably in the writings of Lewis and Clark—the word is employed to describe physical characteristics of bird beaks, where a convex form helps articulate specific details of shape and proportion ([1], [2], [3], [4], [5], [6], [7], [8], [9]). Similarly, in scientific and technical texts, convex is used to denote geometric or optical properties, such as in descriptions of lenses in detective fiction ([10], [11], [12]) and in precise mathematical definitions like that of a convex polyhedral angle ([13]). The term also finds its place in military literature, where “convex order” denotes a particular formation or arrangement in battle strategies ([14], [15], [16], [17], [18], [19]), and even in botanical descriptions, it characterizes the shape of seeds and vessels ([20], [21], [22]). Additionally, authors apply the adjective metaphorically to human features, adding depth to character portrayals ([23]). Overall, "convex" is employed to evoke a clear, tangible image of curvature, bridging scientific precision and evocative narrative detail.
