## ABOUT THIS WORD

## What is the *infinity symbol*?

The *infinity symbol*, a figure eight on its side â, variously signifies the concept of limitlessness or eternity, especially as used notationally in mathematics and metaphorically with respect to love.

## Where did the *infinity symbol *come from?

The* infinity symbol*, sometimes called the *lemniscate* in algebraic geometry, has been in use for hundreds of years. Although the concept of *infinity* has been documented since the Ancient Greek mathematicians and philosophers, the symbol as we now know it was first used by English priest and mathematician John Wallis in 1655. Itâs not clear exactly why Wallis chose the symbol, though its shape does handily represent an endless curve; historians note that a similar figure appears in early Christian iconography and the Ancient Romans employed a series of numerals denoting âmanyâ that resembled the figure eight.

The *infinity symbol* became a very popular aesthetic trend beginning around 2011. It now has meaning beyond the realm of math, and it is often adapted by others to be used in expressions of never-ending love or individual empowerment (tied to the concept of being eternal and, thus, unbreakable). Because of the attraction of its simple design and deep meaning, the *infinity symbol* has become a popular emblem in fashion and accessory design, most commonly in the form of jewelry and tattoos. Double infinity symbols are a popular design for couples or close friends, with the suggestion of a balanced relationship between unique yet intertwined individuals.

Its popularity began to decrease near the end of 2015, when it began to be viewed as clichĂ© and basic. Though still popular, the *infinity symbol* as a personal statement can have a slightly negative connotation due to its somewhat mainstream status now.

Similar ideas of endlessness have been conveyed in the art world by the ouroboros symbol, the ancient image of a snake eating its own tail. Sometimes the ouroboros is depicted as two snakes entwined, and sometimes the snake(s) make the figure-eight shape or simply a circle. The ouroboros is most commonly interpreted as a representation of the cycle of life and death, although it has had different meanings across many cultures.

## How to use the *infinity symbol*

The *infinity symbol* is still used in its original algebraic meaning in scientific fields such as calculus, computer science, and physics. It is also popularly used in graphic design to evoke ideas of eternity, and it often provides a jumping-off point for logo designs.

The *infinity symbol* as it appears in personal fashion may be used in total sincerity, as with a romantic couple who wish to express their eternal love for one another (i.e., having the actual figure-eight symbol on a necklace, earrings, ring, or matching tattoos), but often, the term* infinity symbol* is used humorously. Because the* infinity symbol* now has a strong association with its popularity among young white women as a tattoo, it is often mocked as superficially deep, pretentious, or appropriative, though these judgments may overlap with general ridicule young women face in society.
