“I don’t quite have a science tattoo, but I have a math tattoo. That’s close enough, right?”Now, for the explanation. This is a formula called the Y Combinator. It is a fixed-point combinator in the lambda calculus and was discovered by Haskell Curry, a rather prolific mathematician and logician whose work helped start Computer Science.

“What this formula does is calculates the fixed point of a function, which in turn allows for recursion by calling on that fixed point; recursion is perhaps the single most important concept in Computer Science. Being a computer scientist and a mathematician, this formula is very important to me and represents the innate beauty of computer science and mathematical logic.” –Mark

“I got this on Saturday, that’s it fresh off the needle. When it’s healed I’ll try and take a full arm shot so you can see it all. the artists original design had ‘seek and you will find’ but that’s too close to the biblical reference ‘..shall find’ so i changed it to just ‘seek seek seek’ on the banner. you’re not always gonna find your answers but you should always be looking for some.” –Damien

“Attached is a photo of a tattoo I got immediately after turning in the final paperwork a little over two weeks ago for the completion of my Ph.D. in biological anthropology. It’s the first evolutionary tree that Darwin sketched in his 1837 Notebook B on the transmutation of species.” –Julienne
