The word infinity is derived from the Latin word, infinitas. It refers to the concept of never ending or limitlessness, boundlessness, without end. In mathematics it is often used in the context of numbers as in “an infinite number of items’ or the ‘limit as it goes to infinity.”The symbol for infinity is ∞. The mathematician John Wallis is credited with introducing the symbol to mathematics in the mid-1600s. One popular explanation suggests that the shape is derived from the Mobius Strip, a figure with no beginning and no end.
