The "Thresholds" and "Units" of Big History
Big History is organized in both non-traditional and non-traditional ways...
- Thresholds: Big History is not your traditional history course. One example is how it organizes the 14 billion years of history, the 8 "Thresholds" of increasing complexity which mark the primary organization of the course.
- Units: The traditional way that history is organized in schools is by "Units" (aka "Periods", "Eras", etc.). In Big History there are 10 "Units" that overlap, and at times match-up with the "Thresholds" of Big History.
