Day 14/67: Five Month GED, Our Numerals, and mass transit

     We would have no transportation, public or otherwise, without a numbering system that allows us to calculate precise locations?   

     Decimal numbers, based on Arabic numerals, 640px-Arabic_numerals-en.svg  

give us both precision and the ability, thanks to our positional numeral system, to express any number in fairly limited space (just try writing 10 billion in Roman Numerals!). 

      Our numbers, or rather, the symbols that we use to represent numbers, come from India via the Arabs, during the Middle Ages (“… up to the end of the fifteenth century“).

      Any advocate for a democratic citizenry must both learn and share an understanding of number as system and statistic(s), for democracy to work well (there is also a need for good mass transit used by the middle classes, for a democracy to work well, see Project Do Better, linked below…).

Helpful Actions:

1.) Find three different sources describing the source of our current numbering system/symbols,

2.) Share your  findings with us, and, if you are more curious, tell us whether the Maya, the Aztec, or the Inca had a positional numeral system.

3.) Write a book, story, blog post or tweet that uses those findings, and then, please tell us about it! If you write a book, once it is published please consider donating a copy to your local public library.

    1. Maybe, I’d not thought of it as inspirational, but yes, that is precisely what I am trying to do: inspire action based on empathetic long term planning.
      Ok, is there a way to add this blog to the Inspirational category?
