- Metric system
- Human Era calendar
- Tau (τ) instead of pi (π)
I’ll try to elaborate more later but wanted to get that idea out there. The first one should be familiar to you. Technically the US uses the metric system and converts those measurements to English units.
The Human Era or Holocene calendar simply adds a 1 to the front of the year. So it’s 12,018HE instead of 2018AD, and next year will be 12,019. It’s based on the premise that we should make our Year Zero when the first city (town) was built some 12,000 years ago in Turkey. It’ll be easier to remember dates. It basically marks the beginning of civilization.
Tau is simply 2 Pi. Mathematically they are the same. But it is easier to understand the math around this irrational but very important number around 6.28318… and not 3.14159…
