Where 1957 fits
Why 1957 is special
Sputnik was a polished metal sphere 58 cm across that did little but transmit a radio pulse, and its importance was entirely in demonstrating that it could be put there at all. The American response reorganised science education and created what became NASA within a year.

- History
In 1957, the Soviet Union launched Sputnik 1, the first artificial satellite.
- Science
Sputnik 1 was 58 cm across and did little beyond transmitting a radio pulse. Its significance was entirely in proving the capability existed. The American response reorganised science education and produced NASA within a year, which is a large consequence for an object that simple.

1 × 1,000 + 9 × 100 + 5 × 10 + 7 × 1 = 1,957. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

32 × 60 + 37 = 1957. 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.
