Infinity is something we are introduced to in our math classes, and later on we learn that infinity can also be used in physics, philosophy, social sciences, etc. Infinity is characterized by a number of uncountable objects or concepts which have no limits or size. Infinity can be noted by a specific mathematical sign known as the infinity symbol (∞) created by John Wallis, an English mathematician who lived and worked in the 17th century.
The infinity symbol (∞) represents a line that never ends. The common sign for infinity, ∞, was first time used by Wallis in the mid 1650s. He also introduced 1/∞ for an infinitesimal which is so small that it can’t be measured. Wallis wrote about this and numerous other issues related to infinity in his book Treatise on the Conic Sections published in 1655. The infinity symbol looks like a horizontal version of number 8 and it represents the concept of eternity, endless and unlimited. Some scientists say, however, that John Wallis could have taken the Greek letter ω as a source for creating the infinity sign.
Overall, there are three major applications of infinity symbol:
- the mathematical
- the physical
- the metaphysical
In math, the infinity symbol is used and treated just like it is a number, but this number isn't a specific one. It only represents the concept of endlessness. In metaphysics, this symbol is associated with stability and harmony. In Chinese philosophy, the symbol ∞ is linked to good luck and success. Actually, every person has a kind of own imagination about the concept of infinity: for some people it means freedom, for others it means life, love, or such.
There are a few ways to display the infinity symbol using HTML codes. Probably, the easiest way is to use the menu Insert, select the option Symbol and then find the Infinity Sign among the symbols offered by the computer. You can also copy paste the infinity symbol from this very website or any other one. Finally, it is possible to use the infinity code in your document. See some examples below:

Infinity Symbol Examples
If x is a real number, then we can write as:
- -∞ < x < ∞
- ∞ + x = ∞
- ∞ - x = ∞
- ∞ * x = ∞
- ∞ * ∞ = ∞
- -∞ * -∞ = ∞
- ∞ + ∞ = ∞
- -∞ + -∞ = -∞
- x - ∞ = -∞
The infinity sign is also sometimes called the Lemniscate. Both are believed to be coming from the number 8 sign. This number symbolizes eternity, balance and cosmic order. The number 8 has always been a very important symbol in many ancient cultures, especially in the Far East.
Modern Use of Infinity Symbol
The original meaning of the infinity symbol refers to the union between male and female, duality and perfection. In modern times, there are plenty of very popular usages of the infinity sign, i.e. in jewelry design, tattoos, wall art, clothing, decoration, accessories, and many more. This symbol has a special and very powerful meaning for couples in love as it is believed to represent a promise of eternal love. Thus, an infinity jewelry can be a perfect gift for your loved one. You can choose an infinity name necklace, a pendant, an infinity ring, or an infinity bracelet. Because of the infinity sign is so simple and meaningful, today its popularity is increasing.
Besides, the infinity symbol also represents infinite possibilities and total harmony in social life of modern people. The sign has been used by the Avon Foundation for Women to represent lives with unlimited potential, free from violence and gender related misunderstandings. In 2012, Reese Witherspoon announced Empowerment Circle of Support Necklace in recognition of the International Women’s Day on March 8th.
Georg Cantor (1845-1918) was a German mathematician and a creator of set theory which is one of the fundamentals of mathematics. His work is the basics of modern understanding of infinity. We can say that he was the first mathematician to understand the concept of an actual infinity and give it a mathematical construction. Moreover, this concept plays an important role in other sciences like philosophy, religion, etc.

The Infinity Sign in Annihilation
Annihilation is a 2018 science fiction movie directed and written by Alex Garland. It is based on the novel by Jeff VanderMeer and features amazing performance of Natalie Portman, as well as a team of other actors. In the course of the movie, one can notice a figure 8 tattoo placed on Lena's (Natalie Portman) left forearm. On that tattoo, the infinity is represented as a snake eating its own tail (known as Ouroboros) which symbolizes the cyclical nature of life and self-destruction in the film. It is a mark of the infinite circle of evolution and changes.
Ouroboros is an ancient symbol depicting a serpent, dragon or snake eating its own tail. The symbol represents the continuous cycle of life and destruction and it has been used in various cultures throughout the history. The word derives from an ancient Greek word meaning "tail-devouring". It also was illustrated in various versions of the infinity symbol. In modern times, the ouroboros symbol is often found as a tattoo or jewelry decoration. For example, The X-Files' Dana Scully has got a tattoo of Ouroboros in the episode "Never Again".
