Infinity means something which does not have a limit. The infinity sign ∞ is called a lemniscate. The sign was devised by an English mathematician John Wallis in 1955 and was named lemniscus, meaning a ‘pendant ribbon’, by mathematician Jacob Bernoulli in 1694. The symbol is designed in two dimensions as a device known as the Möbius Strip (named after a 19th century mathematician August Ferdinand Möbius). A Möbius Strip is a strip of paper which is twisted and attached at the ends, forming an ‘endless’ two dimensional surface.
