ABSTRACT
In this chapter, the term “phenomenon” is treated as any event, series of experimental facts or experience that is apparent to the senses and measuring instruments, and that can be scientifically described. In turn, the term “property” means a characteristic quality regarded as being possessed by a material or a group of materials and that is common to all the members of this group. “Process” is defined as a continuing development involving many changes or transformations of material structure and properties. Within this framework, phenomenon is a conjunction of the property and the process.
