Where 1614 fits
Why 1614 is special
Napier's tables turned multiplication into addition and cut the labour of astronomical calculation enormously. Laplace said they doubled the working life of an astronomer.
Same number, different meanings
How 1614 is understood across different contexts — never implying one meaning because of another.
- Mathematics
Napier's tables turned multiplication into addition and cut the labour of astronomical calculation enormously. Laplace said they doubled the working life of an astronomer.
- Technology & computing
In 1614, John Napier published his description of logarithms, transforming calculation (Scotland).
- Science
Napier's 1614 logarithms let a calculator replace multiplication with addition using a table. The saving in astronomical work was so large that Laplace described it as doubling an astronomer's life.

In historical numeral systems
Egyptian
1 lotus, 6 coils of rope, 1 hobble, 4 strokes
1 × 1,000 + 6 × 100 + 1 × 10 + 4 × 1 = 1,614. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
2 corner wedges + 6 vertical wedges (sixties place), 5 corner wedges + 4 vertical wedges (units place)
26 × 60 + 54 = 1614. 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.
