Scientists to the streets. Science, politics and the public moving towards new osmoses

What may be defined as the "standard model" of the public communication of science began to develop in the second half of the nineteenth century, gained a clear structure (especially in an Anglo-Saxon context) in the first three decades of the twentieth century and dominated until the nineties. Roughly speaking, the model tends to describe science as a compact social (and epistemic) corpus, largely separated from the rest of society by a type of semipermeable membrane. That is, information and actions can flow freely from science to the rest of society (through the application of technologies and the spread of scientific culture, for instance), but much more limitedly in the opposite direction (through science politics or the influence of sociocultural events on science itself).
