An enormous amount of new knowledge on the molecular basis of various biological phenomena has emerged in the rapidly expanding field of bioscience. Since the frontiers in scientific research are difficult to define, the creation of new knowledge depends not only on new methods and concepts but also on interaction with other fields of research. The principles and methods of biophysics should be a rational language for discussion not only between scientists of the different disciplines of natural sciences, such as physics, mathematics, biochemistry, molecular biology and biotechnology, but also for medicine and social sciences as well. This is the general philosophy behind the organization of
