Infinity represents something that is boundless or endless or else something that is larger than any real or natural number. Since the time of the ancient Greeks, the nature of infinity was the subject of many discussions among philosophers. In the 17th century, with the introduction of the infinity symbol and the infinitesimal calculus, mathematicians began to work with infinite series and what some mathematicians regarded as infinitely small quantities, but infinity continued to be associated with endless processes. As mathematicians struggled with the foundation of the calculus, it remained unclear whether infinity could be considered as a number or magnitude and, if so, how this could be done.
