ABSTRACT
This chapter discusses the aims of modern physics. Scientific knowledge is very different from the knowledge of any single event or process. Science endeavours to obtain knowledge which is quite general, and if it is dealing with natural events, an attempt is made to discover laws which govern a whole group of phenomena. And the more numerous the individual results expressed in any one law are, the greater does the significance of that law become. Amongst all the results which have led to the formulation of such laws, there is a few which stand out prominently before all others; they are those which have enabled different groups of phenomena, apparently having no connexion with one another, to become correlated. The great dividing wall between the world of atoms and the world of waves has to be broken down. The whole structure of physics is involved. Any further development of natural laws appears to be impossible.
