# Infinity Symbol ∞

**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. This concept can be used to describe something huge and boundless. It has been studied by plenty of scientists and philosophers of the world, since the early Greek and early Indian epochs. In writing, 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
