Chronology is the story of us influencing one another, building from inquiry and conflict into discovery and understanding. Placing facts and skills within the great timeline of human history provides our children with models of reasoning and inquiry they can effectively recall their entire lives. The powerful combination of simultaneous diachronic and synchronic study reveals the development of history, science, philosophy, mathematics, literature, art, and language in order, from the very beginning until now.

Synchronic
The Story of a Time
Diachronic
The Story through Time

Synchronic study -- at the same time -- reveals the breadth of historical movements. All the subjects interrelate during every period of time. The political history of a period is connected with scientific discovery or concurrent developments in philosophy. Mathematical discovery often followed artistic expression.  Literature follows, and pushes, language into newly spoken and written forms. Chronos describes these interrelated subjects week by week, revealing that nothing develops in a vacuum and one discovery can affect people far beyond its field. 

Diachronic study -- throughout time -- reveals the motivations of thinkers and creators, the causes of nations and collapses, connecting them with their influences and successors on the winding, stuttering path humanity has followed to our time and place. Every influencer was influenced herself. Every King succeeded someone. Chronos reveals these cause and effect relationships over four years then returns to the beginning, recursively investigating deeper and broader connections between neolithic and modern man.
