Abstract
Abastrat. The paper stars from the cognitive analysis of an imaginary debate - reconsructed with excerpts from historical sources - concerning the shapes of particular sections of a right cone and a right cilinder. An exporatory study with expert university students was carried out to validate the hypothesis that when conic sections are concerned break between the figural and the conceptual aspect occurs.
