Why 600 is special

Unlike the 206 bones, this count is genuinely unsettled. Anatomists differ over whether a muscle with several heads is one muscle or several, so published figures run from about 600 to over 800 without anyone being wrong. It is a good illustration of a number that looks like a measurement and is actually a convention about naming.

1 × 512 + 0 × 256 + 0 × 128 + 1 × 64 + 0 × 32 + 1 × 16 + 1 × 8 + 0 × 4 + 0 × 2 + 0 × 1 = 600

Octal

1 × 512 + 1 × 64 + 3 × 8 + 0 × 1 = 600

Hexadecimal

2 × 256 + 5 × 16 + 8 × 1 = 600

Read as powers of two: 512 + 64 + 16 + 8 = 600.

In historical numeral systems

Egyptian

6 coils of rope

6 × 100 = 600. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Babylonian

1 corner wedge (sixties place), empty units place

10 × 60 + 0 = 600. Places are separated by a space on the tablet, with the higher place written first. The second place is empty, and this is precisely the case the early system could not write unambiguously — the same wedges alone would also read as 1.

Greek (Ionic)

chi, marked as a numeral

chi + keraia

A single letter, chi, marked with a keraia to show it is a number rather than a word.

Hebrew numerals

tav, then resh

tav-resh

tav (400) + resh (200) = 600, written in descending order.

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.

Everyday life

  • There are about 600 thousand words defined in the Oxford English Dictionary (English). Not the size of the language: the dictionary excludes most technical vocabulary, and counting chemical names alone would run past a million.

Science

  • There are about 600 skeletal muscles in the human body (humans; published figures range from about 600 to over 800). Anatomists disagree about whether a muscle with several heads counts once or several times, so the spread is a naming disagreement rather than a measurement error. Unlike the 206 bones, no conventional figure has settled.
