Why 1824 is special
He was profoundly deaf and had to be turned around to see the applause he could not hear. Its Ode to Joy is now the anthem of the European Union, without words to avoid privileging a language.

- Technology & computing
In 1824, Joseph Aspdin patented Portland cement, the binder in nearly all modern concrete (England).
- Culture
The Ode to Joy became the European anthem in an instrumental arrangement, deliberately wordless so that no member state's language is privileged. A choral finale is used officially by removing the choir.

1 × 1,000 + 8 × 100 + 2 × 10 + 4 × 1 = 1,824. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

30 × 60 + 24 = 1824. 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.

Related numbers & connections
1824 is a year in the 19th century, in the 1820s.
The Marriage of Figaro premiered in 1786 with its politics stripped out, and Beethoven's Ninth premiered in 1824 and is now the European anthem without its words. Both lost text on the way to acceptance.
