This afternoon I have visited the Star Wars exhibition at the"Cité des Sciences" in Paris... There is a strange relation between science & technology and science-fiction (SF). They respectively influence themselves in a deep and necessary loop. SF was made possible only by the rise of modern science itself. All SF Writers have been deeply influenced by the advances in science and technology. But in turn, scientists are also influenced by SF novels and movies. SF is an incubator for imaginative minds to create visions, to transport us beyond the horizon of our current technologies. SF enable us to "experiment" the possible incarnations of scientific progress not only as it is, but also as it could be, to paraphrase the terms coined by Christopher Langton for Artificial Life. In this sens, SF offers an imaginary window to possible futures.
