What does ∞ mean?

El símbolo de infinito ∞, denominado matemáticamente lemniscata, fue introducido en 1655 por el matemático británico John Wallis para representar una magnitud sin límite numérico. En análisis matemático y cálculo diferencial se emplea para denotar sucesiones divergentes, límites infinitos y cardinalidad de conjuntos no acotados.

Fuera de las ciencias exactas, el signo de infinito simboliza la eternidad, el amor imperecedero y los ciclos continuos de renovación. Se integra habitualmente en joyería, moda y perfiles sociales.
