Abstract
The first aim of science has been analysis. From Leucippus in the fifth century B.C. to Sir Arthur Eddington today, science has tried to reduce nature to simple structural units. For Leucippus the atoms are structurally alike, though they differ in external characteristics, such as size and shape. The aim of physics today is expressed by Sir Arthur Eddington: “The aim of the analysis employed in physics is to resolve the universe into structural units which are precisely alike one another... so that all variety originates in the structure and not in the elements out of which the structure is built.” To be sure, that is an ideal. In practice we speak of electrons, protons, neutrons. But that does not alter the problem. The question is: Are there such structural units?
