The algebraic equation graphs the heart in the background on a line graph. Al-jabr is the Arabic word from which we derived the word Algebra. Al-jabr literally means "the reunion of broken parts". This is a "rebirth" tattoo.
It is a design by SymbolGrafix. The tattoo artist is Masato Kaisawa from Mexico City. I did it at special Pi day, to pay my respects to mathematics as a symbol of unity, curiosity and the pursue of knowledge. Also, I am a physics engineer.
