In this contribution, we discuss and analyze some aspects of nanoscience and nanotechnology, based on the approach kwon as Science, Technology and Society (STS), as well as the prospects of Philosophy of Technology. In this context, we specify the constitute the nanoscience and nanotechnology analytic research field. I is also reported its genesis and limits, emphasizing the impacts of nanotechnology in the development of the contemporary society, such as the possible benefits and problems associated to the use of nanotechnology, as well as environmental impacts, doubts and uncertainties that permeate this areas, in addition some ethical questions and public policies for the sector are analyzed.

In this contribution, we analyze conceptual approaches to nanotechnology and nanoscience in recent issues of secondary education of Brazilian physics textbooks. We analyzed fifteen collections of Physics textbooks of recent editions, however, only two books, belonging to different collections incorporate considerations about nanotechnology and nanoscience in their approaches. We focus our analysis on three aspects, namely: the place dedicated to approaches to nanoscience and nanotechnology, notions about technology and its contributions to critical scientific education. This is a qualitative research; it was used as conceptual approaches the Philosophy of Technology, The Discourse Analysis (DA) and Science, Technology, Society (STS) concepts. We found that in two examined textbooks the approaches to nanoscience and nanotechnology is a complementary description of modern physics, associated with quantum theory. In this context, the concepts of nanoscience and nanotechnology focus superficially in the genesis of the field and some possible areas of applications. It was not identified in all textbooks warnings about the potential risks to human health and the environment from the use of nanotechnology and nanoscience. We understand that textbooks approaches about nanotechnology and nanoscience round a instrumental technological perspective, however keep away from the scientific and technological critical education.

In the early 1960s, after his experience as a film critic in the Jornal da Bahia, the young Glauber Rocha began his collaboration in the Suplemento Artes e Letras of Diário de Notícias in Salvador. Inserting itself the symbolic disputes in defense of a film art of authentic Brazilian nuance, the activity of the critic Glauber Rocha represents a voice that demarcates the internal tensions of the field of cinema in Bahia and outlines, in the form of genesis, his most famous manifesto, “An esthetic of hunger” (1965). For this analysis were focused mainly two critics: “Experiência ‘Barravento’: confissão sem moldura”, published December 25-26, 1960, and “Luz Atlântica, 1962”, published in December 31, 1961.
