Where 1394 fits
Why 1394 is special
It was technically superior to early USB for video and had guaranteed bandwidth, and it lost anyway — largely because Apple charged licence fees per port.
Same number, different meanings
How 1394 is understood across different contexts — never implying one meaning because of another.
- Mathematics
It was technically superior to early USB for video and had guaranteed bandwidth, and it lost anyway — largely because Apple charged licence fees per port.
- History
In 1394, Benedict XIII was elected at Avignon and refused for decades to resign (Europe).
- Technology & computing
IEEE 1394 specifies a serial bus with isochronous transfer guaranteeing bandwidth for streaming. It was standard on camcorders and professional audio equipment before USB displaced it in consumer use.

1 × 1,000 + 3 × 100 + 9 × 10 + 4 × 1 = 1,394. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
2 corner wedges + 3 vertical wedges (sixties place), 1 corner wedge + 4 vertical wedges (units place)
23 × 60 + 14 = 1394. 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.
