This tattoo has to be adorned by the science freaks. Having these long equations embodied on your body seems to be the best option to memorize them. This oneâs surely for the books but yâall know, there is no end to the craziness these tattoo freaks can go to. Imagine someone having these long equations on his body, going through so much pain to get the equation inscribed and in the end gaining nothing, not even a cute look!! awwwww..
