From the past to the present - - historical
From the simplest to the most complex - - chemical?
From the visible to the invisible - - biological? [Spiritual. -Dave]

From the known to the unknown - - philosophical?
From the local to the global - - the geographical?
From the familiar to the unfamiliar - - the successful? ;-)
