Where 1810 fits
Why 1810 is special
Canning preceded a practical can opener by nearly fifty years; early instructions suggested a hammer and chisel. Preservation and access are separate problems and were solved separately.
Same number, different meanings
How 1810 is understood across different contexts — never implying one meaning because of another.

- History
In 1810, independence movements began across Spanish America, in Mexico, Venezuela, Argentina and Colombia within months of one another (Latin America).
- Technology & computing
Tin cans were patented in 1810 and the first can opener appeared around 1858. In between, cans were opened with hammer and chisel, which is a clean illustration of a technology arriving before its complement.

In historical numeral systems
Egyptian
1 lotus, 8 coils of rope, 1 hobble
1 × 1,000 + 8 × 100 + 1 × 10 = 1,810. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 corner wedges (sixties place), 1 corner wedge (units place)
30 × 60 + 10 = 1810. 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.
