1012 connects to 3 worlds: mathematics, history, related numbers.

Why 1012 is special

It distinguishes building the product right from building the right product, and assigns effort by integrity level rather than uniformly.

1012 connects to:

  • historical years — appears in
  • 61508 — is associated with
  • 1044 — is associated with

In historical numeral systems

Egyptian

1 lotus, 1 hobble, 2 strokes

1 × 1,000 + 1 × 10 + 2 × 1 = 1,012. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Babylonian

1 corner wedge + 6 vertical wedges (sixties place), 5 corner wedges + 2 vertical wedges (units place)

16 × 60 + 52 = 1012. Places are separated by a space on the tablet, with the higher place written first.

Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
