We believe that the scientific criteria for the existence of two possible changes in the way: 'peaceful evolution' and 'violent revolution'. The so-called 'peaceful evolution' of the strategy is to play and extended by adhering to the existing scientific research guidelines obtained under the premise of the new achievements of science to change the view of nature assumes that the scientific criteria to support the change. 'Peaceful evolution' is the mainstay of mainstream scientists, invoking the concept of resources, primarily from within the scientific community, the scientific criteria for change is gradual, peaceful, even unknowingly, or that the scientific criteria for the process of gradually changing scientific principles are still maintained a considerable degree of continuity (in fact the development of modern science is one such, but it seems few people are consciously and conscientiously do so), so do not cause too strong a cultural conflict.
