11 Great Geeky Math Tattoos

1. Polly Want A Tattoo?

It shouldn’t be all too surprising that when it comes to math tattoos, Pi designs are the most common. The majority of these designs are either blocks of numbers or the basic Pi symbol. But at least one person came up with a more creative tattoo: They used the symbol as a perch for a parrot named Pie. I can’t tell you who owns Pie and has this great tattoo, but I can tell you it was done by artist Shannon Archuleta.

2. I Heart Pi

When it comes to tattoos of Pi number strings, Scruffy’s design is one of the best: She used the numbers to create the shape of a heart. As one Geeky Tattoos commenter pointed out, it works on a second level because no one knows how long Pi goes on, just as no one knows the depths of true love.

This lovely tattoo was done by Steve at Art Freek Tattoo.

3. Sea Spiral

Perhaps second behind Pi in math tattoos is the Golden Spiral. While there are plenty out there, Thom’s version, which shows the perfect ratios of a nautilus shell, is by far one of the most visually striking—and it certainly does a good job at reflecting his stance that mathematics is the language of nature.

4. The Number Game

While the digits making up the Golden Ratio tend to not look as aesthetically appealing as the image of a Golden Spiral, Milad’s tattoo is still fascinating—especially because he ensured that the rectangle formed by the digits features sides in the proportion of the Golden Ratio. Milad got the design because the Golden Ratio is the precise reason he became fascinated by math at a young age, and because the design is the closest mathematical explanation of beauty.

5. A Strong Foundation

Mark’s tattoo might not be the most stunning out there, but it’s still something close to his heart: He loves math so much that he chose to get the Zermelo-Fraenkel with Choice axioms of Set Theory, the nine axioms that make up the foundation of mathematics.

That’s not Mark’s only math tattoo. On his other arm, he has the Y Combinator formula.

6. Have A Heart

After learning her mother was diagnosed with breast cancer on Valentine’s Day, Josephine got a tattoo of one of the formulas for a heart curve, a fitting symbol of support and a great tribute to any loving mother.

7. The Gods of Math

Alison is a high school physics teacher who also studies world religion and draws spiritual inspiration from the natural laws of the universe. To reflect this approach to life, she decided to get the Mandelbrot set, the equation for hydrostatic equilibrium, the equation describing entropy, and the Delta symbol on her back to symbolize the powers of creation, preservation, destruction, and change in the world.

8. Schrodinger’s Tattoo

In the future, Brittany hopes to be what she calls a “wacky, flannel-sportin’ physicist." Her first step toward achieving that goal was getting Schrodinger’s equation for the wave function of a particle tattooed on her back, because it represents the fundamental source of “quantum weirdness.” She says she likes the design because it reminds her that “no matter what happens in my life, there is an infinitely Glorious Plan swirling all about us.”

9. HumbleBragg

Josephine Schuppang studied Crystallography at the Technical University in Berlin. After writing her thesis on the transmission electron microscopy of nitride semiconductors, she wanted to get a tattoo to mark the occasion, but because all the formulas she used were too long and complex, she decided to stick with the fundamental formula of Bragg’s Law.

10. Musical Math

Here’s one most of us probably remember from algebra. That’s right, it’s the legendary Quadratic Formula. Sharon, an undergraduate math student at Arcadia University, got the design to show her love for mathematical formulas and equations. This particular formula is one of her favorites because she learned to sing it to the tune of “Pop! Goes the weasel"—which means this is probably the most musical of all math tattoos as well.

11. Spaced Out

Juan Barredo spotted this lovely set of Maxwell’s Equations on the back of a fellow attendee at the Space Frontier Foundation’s NewSpace Conference in Washington D.C. The equations, which relate to space-time formulations, certainly fit in at a place like that.

Special thanks to Discover magazine’s Science Tattoo Emporium, which is loaded with great math and science tattoos (as the name implies). I know plenty of you Flossers have tattoos and when we posted the librarian and book tattoos articles, many of you posted your own photos of tattoos that fit in those categories. So do any of you math-lovers have formulas or mathematical symbol tattoos? If so, please share them in the comments!

Stanley Kubrick will forever be known as one of the most important film directors of the 20th century, but he started his career in the 1940s as a photojournalist for Look magazine. Now, the Museum of the City of New York will host a photographic exhibition of Kubrick’s early work, featuring 120 pictures from his time as a staff photographer at Look from 1945 to 1950.

Much of Kubrick’s work at the time revolved around daily life in New York City—the clubs, the commutes, and the sports. Some of his most notable pieces while at Look were his photo features on boxers Rocky Graziano and Walter Cartier, the latter of which became the subject of Kubrick’s first film, a 1951 documentary called Day of the Fight.

“Turning his camera on his native city, Kubrick found inspiration in New York's characters and settings, sometimes glamorous, sometimes gritty,” the museum wrote in a press release. “He produced work that was far ahead of his time and focused on themes that would inspire him through his creative life. Most importantly, his photography laid the technical and aesthetic foundations for his cinematography: he learned through the camera's lens to be an acute observer of human interactions and to tell stories through images in dynamic narrative sequences.”

Titled "Through a Different Lens: Stanley Kubrick Photographs," the exhibition will detail the different themes that inspired Kubrick’s work, as well as guide patrons through his Look tenure, including both published and unpublished work. One of the exhibit’s goals is to provide an “examination of the direct connection between Kubrick the photographer and Kubrick the director.”

"Through a Different Lens" runs from Thursday, May 3 through October 28, 2018 at the Museum of the City of New York.

8 Expert Tips and Tricks for Hanging a Picture Right the First Time

Framed pictures are an inexpensive way to make a house feel like a home, and they can take a room from empty to finished-looking in minutes. They can be customized easily to your space and decor, and swapped out if your tastes change. But there is an art to hanging a picture the right way—without destroying your walls. Here’s what you need to know.


There are several steps you need to take before you get anywhere near a drill or hammer. First, consider two factors: the state of the wall you want to decorate, and the weight of the picture. Your wall may be supported by studs, which are pieces of wood or metal that run vertically behind the wall every couple of feet. Screwing directly into a stud can provide more support for hanging items.

If you have a reinforced wall, you could use a basic nail or screw to hang the frame, as long as you insert the nail or screw firmly into a stud. But you should only ever use a nail if you're hanging on a stud, according to Simon Taylor, owner-operator of T&C Carpentry in Whitby, Ontario. Otherwise, the weight of the picture could rip the nail out of the wall.

No stud? No problem. "If the picture is light, then a product like Monkey Hooks"—a kind of cantilevered hook for unreinforced walls—"work great," Taylor says.

For medium to heavy pictures, use wall anchors, which are plastic or metal inserts that provide more support for screwing into an unreinforced wall. There are many styles and strengths available for different materials and weights. “Using a product like E-Z Ancors is an easy way to fix a screw to drywall where there is no stud to screw into. They are strong and easy to install,” Taylor tells Mental Floss. “You can then thread a screw into them to hang your picture, providing it has a hook on the back or a string. A good rule to follow is not to use anything other than an anchor if you are not screwing directly into a stud or backing.” (Plastic wall anchors are fine for most lightweight projects, but for a really heavy picture, or a wall made out of something besides drywall, you'll need a different type of anchor.)

If you’re renting and don't want to damage the walls of your apartment, or you’re not 100 percent committed to the picture's placement, Taylor recommends a non-nail option like the extremely popular 3M Command adhesive hooks. They provide temporary, hole-free hanging and hold strong without peeling paint off the wall when it comes time to remove them.

Others argue that stick-on hooks can be unreliable, especially for heavier frames. “All picture-hanging hardware should really include some type of component that punctures the wall,” says Claire Wheeler, design and project coordinator for Montreal-based Sajo Inc. “This provides a much more secure hanging system than a hanging system that is surface-applied.” The adhesives on these types of products are more likely to fail than any sort of nail or anchored hardware, she tells Mental Floss.


Wheeler says your hanging hardware depends on the size and weight of the frame. Fortunately, most frame manufacturers include some form of hanger on the back of their products.

While she finds that hook tabs (small triangular hangers on ready-to-use frames) work for hanging lighter pictures, a wire system—two anchor points on the back of the frame and a strong wire strung between them for looping over the wall screw or hook—is the better choice for hanging large and/or heavy pictures. The wire system setup allows the weight of the frame to be distributed evenly along the wire for more secure hanging, rather than placing all the weight of the frame on one small hanger point.

“You will notice that most frames, whether you have purchased them in a store or you've had them custom-made, have hardware already installed at the back. It’s usually a pretty safe bet to use what the manufacturer has provided,” Wheeler says.

To hang a picture without the need for advanced math, start with a center hanging point: a hook tab affixed in the appropriate spot, or, if your frame has two tabs on either side of the frame, a wire strung slackly between them.


Assemble all of the gear before you spring into action. In addition to your framed artwork, you'll need the proper hanging apparatus for your project (see #1) and a hammer for pounding in the wall anchor or nail. Use a power drill or screwdriver to insert screws in the wall anchor, if you're using one. A tape measure makes it easier to calculate the right spot for hanging. A sturdy wire for the back of your frame is optional (see #2). And the best way to ensure your picture will be level is to, well, use a level. “A level is a basic tool everyone should have,” Wheeler says. “If you own a hammer, you should own a level.”


Wheeler says you should play around with the height at which you plan on installing the frame: “As a general rule, eye level should land within the bottom half of the frame,” she says.

From a designer’s perspective, Wheeler finds people often choose pictures that are either too big or too small in proportion to the wall area. “You want the picture to have some space to 'breathe,' so to speak, meaning a wall large enough that it doesn’t feel as though the picture is overcrowding the wall," she says. "On the flip side, you also don’t want a picture to look completely lost on a big wall."

She adds, "Proportion is important, but there’s no specific ratio" of picture size to wall area that could be considered a rule of thumb. Ultimately, you're the best judge of your space.


Place the frame against the wall where you want it to hang. "It’s a good idea to have someone with you to judge if it is in the right place," Taylor says. "Having a view of it in place before it’s 'fixed' to the wall will help you decide if it looks right."

After you've picked your spot, draw a short line with a pencil along the center of the frame's top edge as your reference line. If you're hanging a really large picture, get your assistant to hold it in place while you draw.


Lay the frame face-down on a flat surface. Place your wall fastener, such as the wall anchor or Command hook, in the appropriate hook tab or on the wire on the back of the frame and pull the wire taut. With a tape measure, measure the distance from the top edge of the frame to the center of the fastener.


Now back to the wall: Measure the same distance from the center of your penciled reference line down. Mark that spot with your pencil: That's where you're going to install your fastener.

If you're not using a wall anchor, simply affix an adhesive hook, hammer in a nail, or insert a Monkey Hook.

To install an anchor, drill a hole into the wall at the penciled point with a screw that is narrower than the anchor itself. (You don't want the anchor to be too loose in the wall.) Don't screw it too tightly. Next, reverse the drill's direction and pull the screw out. Insert the anchor, hammering it flush against the wall. Finally, drill the screw into the anchor—this action makes the anchor expand slightly and press against the drywall's innards, creating a more secure fit. Be sure to leave a bit of space between the screw's head and the wall so the picture's wire can be hooked over the screw. Hang the picture.


To make sure your picture is straight, rest the level along the top of the frame, against the wall. Then, adjust until the air bubble within the small tube of water is in the center of the tube, which indicates that the bar is parallel to the floor—and, therefore, that your picture is level.

Taylor says that not using a level and assuming the hanging hardware is set evenly on the back of a frame are the two biggest mistakes he sees people make. Pros often use laser levels, but Taylor says a water level will work just as well for most people.
