The interesting part: "The long s survives in elongated form, with an italic-styled curled descender, as the integral symbol ∫ used in calculus."

The notation for the indefinite integral was introduced by Gottfried Wilhelm Leibniz in 1675 (Burton 1988, p. 359; Leibniz 1899, p. 154). He adapted the integral symbol, ∫, from the letter ſ (long s), standing for summa (written as ſumma; Latin for "sum" or "total").
