Is it a coincidence that infinity has 8 letters, and the symbol for infinity is a figure 8?

Asked by Ltryptophan (10280points) December 26th, 2010

Seems like more than a coincidence.

Isn’t the origin Infinitum? That’s more than 8.

@futurememory but when did the symbol and the word unite in meaning!

Coincidence. There are a few more languages than English, so it’s likely to happen.

Yes. That just happens to be the way we write it in English, and the number of letters means nothing.

And the symbol isn’t a numeral 8. It resembles one in much the same way that the letter O resembles a zero or a numeral 1 resembles a lowercase l but is not actually the same thing.

The “8” is, I believe, representative of a variation of the Mobius Strip.

The symbol itself is called the Lemniscate and is “by definition” the cross section of a torus. An eight glyph is an evolved form of the ancient India symbol for eight.

As for infinity being a “lazy eight”, the Wikipedia discussion of the infinity symbol notes that: ”...before typesetting machines were invented, ∞ was easily made in printing by typesetting the numeral 8 on its side. ” The article agrees with @Vortico in explaining that the figure ” sometimes called the lemniscate, from the Latin lemniscus , meaning ‘ribbon’. John Wallis is credited with introducing the symbol in 1655…” Wallis might have borrowed symbols for large numbers from ancient alphabets.

According to this blog the symbol is “New Latin lemniscata , from feminine of Latin lemniscatus with hanging ribbons, from lemniscus [Attribution given to Meriam-Webster online but I can’t find it.]

In any case there’s no mention of Möbius bands (sorry, @the100thmonkey) & no apparent connection to 8, eight-letter words—or any kind of “8-ness.”

This confirms my initial hunch that it’s just a coincidence. Such occurrences are more common and likely than intuition would suggest. Like all of us humans, @Ltryptophan‘s brain is searching for pattern & meaning in the pageant of life. Didn’t pan out this time!
