This article analyzes a proposal submitted to a funding unit in Michigan Technological University by a PhD Forestry student. A rhetorical-cultural approach of the text provides evidence to argue that scientific writing is rooted in a cultural practice that valorizes certain kinds of thought, practices, rituals, and symbols; that a scientist's work is grounded and shaped by an ideological paradigm; hence, scientific texts have material existence. We find out that science writing is kairotic, selective, and persuasive. The results of the analysis provide enough insights for technical communicators to think about the role that institutions and disciplines play in knowledge production. Thus, technical communicators will not only think about rhetorical moves when they are composing, they will also think about the articulations between contexts and ideological practices and how they shape the identity of writers and communicators.
