Specific theories of social or cultural evolution often attempt to explain differences between coeval societies by positing that different societies have reached different stages of development. Although such theories typically provide models for understanding the relationship between technologies, social structure or the values of a society ...

A central contention of dependency theory is that poor states are impoverished and rich ones enriched by the way poor states are integrated into the "world system".
Band theory derives these bands and band gaps by examining the allowed quantum mechanical wave functions for an electron in a large, periodic lattice of atoms or molecules. Band theory has been successfully used to explain many physical properties of solids, such as electrical resistivity and optical absorption , and forms the foundation of the ...
