Abstract
There are many uncertainties in the knowledge of modern sciences, especially the sciences of complex systems. Here, in the first I discuss the pseudo-sciences and indicate the pseudo-scientific tides due to the uncertainties of complex systems, whose origins are made clear such as chaos, self-organization, butterfly effect, and so on. The uncertainties are intrinsic in complex systems. In the next, I present the possible role of scientific communication, especially stressing how the scientific communicators overcome the uncertainties of sciences. This will become a fatal point of scientific communication. Finally, I add the possible cooperation between the natural and social scientists.
