What is Tattoo: Definition and 26 Discussions

A tattoo is a form of body modification where a design is made by inserting ink, dyes, and/or pigments, either indelible or temporary, into the dermis layer of the skin. The art of making tattoos is tattooing.
Tattoos fall into three broad categories: purely decorative (with no specific meaning); symbolic (with a specific meaning pertinent to the wearer); and pictorial (a depiction of a specific person or item). In addition, tattoos can be used for identification such as ear tattoos on livestock as a form of branding.

    I've been thinking of getting a math-related tattoo, and I decided to go ahead with it, but I'm not sure what it should be. Maybe a small Euler spiral on my wrist? My mother thinks I should get the rational version of the golden ratio, but I think that'd just be lame. Thoughts please?
