Where 3003 fits
Why 3003 is special
It is drink cans, cooking foil and heat exchanger fins — enormous volume in objects nobody thinks of as engineering material.

In historical numeral systems
Egyptian
3 lotuses, 3 strokes
3 × 1,000 + 3 × 1 = 3,003. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
5 corner wedges (sixties place), 3 vertical wedges (units place)
50 × 60 + 3 = 3003. 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.
