Why 1880 is special

Same number, different meanings
How 1880 is understood across different contexts — never implying one meaning because of another.
- Mathematics

- History
In 1880, an international conference in Washington proposed Greenwich as the prime meridian, adopted four years later (United States).
- Technology & computing
Edison's 1880 patent was challenged by Joseph Swan, who had demonstrated a lamp in Britain earlier. Rather than litigate indefinitely the two formed a joint company, which is how the priority question was actually resolved.

In historical numeral systems
Egyptian
1 lotus, 8 coils of rope, 8 hobbles
1 × 1,000 + 8 × 100 + 8 × 10 = 1,880. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 corner wedges + 1 vertical wedge (sixties place), 2 corner wedges (units place)
31 × 60 + 20 = 1880. 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.
