What does ∞ mean?

O símbolo de infinito ∞, chamado geometricamente de lemniscata, foi introduzido pelo matemático inglês John Wallis em 1655 para representar uma grandeza contínua que transcende qualquer limite finito. No cálculo diferencial e na teoria dos conjuntos, expressa limites assintóticos e cardinalidades infinitas.

Fora do campo científico, o infinito virou símbolo popular de eternidade, união duradoura e ciclos de constante renovação espiritual. É frequente em joias e artes visuais. Você pode compará-lo com o símbolo de pi, o símbolo de grau ou verificar a nossa seleção de símbolos matemáticos.
