Where 1908 fits
Why 1908 is special
The Model T made cars affordable through moving-assembly production; Tunguska levelled about 2,000 square km of forest with no crater, and is attributed to an object exploding in the atmosphere. Neither event has much to do with the other beyond the year.
Same number, different meanings
How 1908 is understood across different contexts — never implying one meaning because of another.

- History
In 1908, the Model T went into production, and the Tunguska event flattened Siberian forest.
- Technology & computing
Ford's Model T went on sale, making cars affordable through production method rather than design. Tunguska flattened around 2,000 square km of Siberian forest without leaving a crater, attributed to an object exploding in the atmosphere.

1 × 1,000 + 9 × 100 + 8 × 1 = 1,908. 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), 4 corner wedges + 8 vertical wedges (units place)
31 × 60 + 48 = 1908. 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.
