The infinity symbol (∞), mathematically known as a lemniscate, represents a boundless or limitless quantity in calculus, physics, and geometry. Originally introduced by mathematician John Wallis in 1655, it has evolved far beyond its academic roots into a popular cultural icon used in social media to signify eternal love, continuous loops, or endless possibilities. In Unicode, it sits within the mathematical operators block but remains universally recognized across everyday digital communication.

In Programming
While rarely used directly as syntax in source code, the concept of infinity is usually handled via language-specific constants like `Infinity` in JavaScript or `math.inf` in Python. The literal ∞ symbol frequently appears in LaTeX documentation using the `\infty` command to neatly render complex mathematical formulas.
