Integral symbol The ∫ symbol is used to denote the integral in mathematics. The notation was introduced by the German mathematician Gottfried Wilhelm von Leibniz towards the end of the 17th century. The symbol was based on the ſ (long s) character, and was chosen because Leibniz thought of the integral as an infinite sum of infinitesimal summands.
Thanks to Aaron Hamilton at #aerochildtattoo downtown bahm, I have some new ink! It's a silver fern leaf with Koru symbols in the leaf. Koru is a spiral shape based on the shape of a new unfurling silver fern frond and symbolizing new life, growth, strength and peace. It is an integral symbol in Māori art. Some other legit māori finish off the top of the piece. I'm stoked!! So thanks again Aaron!! #newink #maoritattoo #newzealand #koru #kiakaha #❤ #tattedup
