Abstract

We know that since the Renaissance, scientific knowledge has increased exponentially. The amount of knowledge has now grown to colossal proportions and doubles every fifteen years . The question of digesting scientific information is acute. Even today its scope is such that assimilation of the accumulated knowledge even within a fairly narrow discipline has become virtually a lifetime undertaking for a scientist. It is also necessary to realize that modern science is developing quite rapidly at the junctions of its branches, which makes it necessary to know adjacent and often quite remote disciplines
