Where 1926 fits
Why 1926 is special
Baird's mechanical system showed a recognisable moving human face at 30 lines. Electronic systems replaced the mechanical approach within a decade, so the demonstrated technology was a dead end even though the demonstration was not.

In historical numeral systems
Egyptian
1 lotus, 9 coils of rope, 2 hobbles, 6 strokes
1 × 1,000 + 9 × 100 + 2 × 10 + 6 × 1 = 1,926. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 corner wedges + 2 vertical wedges (sixties place), 6 vertical wedges (units place)
32 × 60 + 6 = 1926. 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.

Technology & computing
In 1926, John Logie Baird demonstrated television, and Goddard launched the first liquid-fuelled rocket (Britain and North America).
DocumentedTechnology & computingGeography: Britain and North AmericaPeriod: 1926Baird's 1926 demonstration proved television was possible using a spinning disc that could never scale. Electronic scanning superseded it within ten years, which makes the demonstration historically decisive and technically a cul-de-sac.

Common questions
Is 1926 a prime number?
No, 1926 is not prime.
What are the factors of 1926?
The factors of 1926 are 1, 2, 3, 6, 9, 18, 107, 214, 321, 642, 963, 1926.
What is 1926 in Roman numerals?
1926 in Roman numerals is MCMXXVI. CM is subtractive: a hundred before a thousand — a thousand minus a hundred. Written additively it would be MDCCCCXXVI, which Roman inscriptions used freely — the strict subtractive form is a later convention.
