“I have my BS degree in Computer Science from East Carolina University, where I currently work as a software engineer. Here is a picture of my Computer Science tattoo. It is of the question P=NP. This unsolved equation is considered by many to be the Holy Grail of Computer Science. Ever since I came across it in a Computability class, its possibilities and implications have fascinated me. I realize that many believe that P!=NP. To those I say “Prove It” (and be sure to remember me when you collect your Million dollar prize from the Clay Mathematics Institute).”

“I’m a physics major that’s going into planetary science and I’ve always been in love with the planets and stars. I actually have two science tattoos. One is the astronomical symbol for Jupiter, my favorite planet, and one of its biggest moons Io. The other one is my favorite constellation, Orion. I chose both of these because I’ve been fascinated by the universe and all it holds since I was really little.”

“This is my math-and-philosophy tattoo. The purple bit is the math symbol for “to define,” used in proofs to set [variable on left] equal to [stuff on right]. The eye is both a rebus for “I” and a symbol for “to observe,” and it’s in front of the definition symbol to indicate that observation comes first, definition follows. Or as Sherlock Holmes put it, “It is a capital mistake to theorize in advance of the facts.” So it means “I observe and then define,” and “Data before decisions,” and “I decide for myself (based on my own observation),” and therefore implies “Think for yourself.”

Mark Siddall, leech master, gets Neil de Grasse Tyson into shorty-shorts and then into a leech-infected Connecticut pond. Even manages to dispense some natural history along the way on leech family values…It’s a teaser for a piece on leeches on NOVA Science Now, which you can watch in its entirety here.

“I was toying with the idea of getting some ink when I came across your Science Tattoo Emporium and was inspired! I’ve always loved water as an element of recreation in both the liquid and solid states. Enjoying a career measuring and predicting stream flow I spend a lot of time in, over and around water. I thought a tat of a water molecule would be just the thing. Talented tattoo artist Rose helped with advice and skill to make my first tattoo an enjoyable experience”
