- Technology & computing
In 1794, the Chappe optical telegraph carried its first official message between Lille and Paris (France).
- Science
Lavoisier was guillotined in 1794 for his role as a tax farmer, not as a chemist. The judge's famous dismissal of science is likely a later invention, which does not change what was lost.

1 × 1,000 + 7 × 100 + 9 × 10 + 4 × 1 = 1,794. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
2 corner wedges + 9 vertical wedges (sixties place), 5 corner wedges + 4 vertical wedges (units place)
29 × 60 + 54 = 1794. Places are separated by a space on the tablet, with the higher place written first.
