You see it on wrists. You see it on coffee mugs. Sometimes it’s on a tombstone. The infinity symbol—that lazy, sideways figure eight—is probably one of the most recognizable icons on the planet, but it wasn't always a "Live, Laugh, Love" aesthetic. Long before it became a Pinterest staple for matching tattoos, it was a heavy-duty mathematical tool. Honestly, its journey from dusty geometry books to modern pop culture is weirder than you’d think.
It’s just a line that never ends. Simple, right? But the human brain hates the idea of things ending. We’re obsessed with forever.
Where the Infinity Symbol Actually Came From
Most people assume this symbol has been around since the pyramids. It hasn't. While ancient cultures like the Greeks and Indians played with the concept of the endless, the actual glyph we use today—the lemniscate—didn't show up until 1655. A guy named John Wallis gets the credit. He was a clergyman and a mathematician, which is a pretty intense combo if you think about it. Wallis was trying to find a way to represent a number that was larger than any possible integer. He needed a shorthand for "this goes on forever."
Why a sideways eight? Wallis never explicitly said why he chose that exact shape. Some historians argue it’s a variation of the Roman numeral for 1,000, which was sometimes written as CIƆ. In those days, 1,000 was basically shorthand for "a whole lot." Others think it’s a version of the Greek letter omega ($\omega$), the final letter of the alphabet, twisted to show that even the end isn't really the end.
Wallis used the infinity symbol to calculate the areas of shapes with infinite divisions. It was a tool for calculus before calculus was even fully a thing. It’s funny to think that a symbol now used to represent "endless friendship" on a Hallmark card started as a way to solve terrifyingly complex area-under-a-curve problems.
Mathematics vs. Philosophy: It's Not All One Size Fits All
In math, infinity isn't a "big number." It’s a destination you never reach. If you start counting now and never stop, you won't hit infinity. You'll just be tired. This is where people get tripped up. There are actually different sizes of infinity. Georg Cantor, a brilliant but troubled mathematician in the late 19th century, proved that some infinities are bigger than others.
Think about it this way: There are infinite whole numbers ($1, 2, 3...$). But there are also infinite decimals between the numbers $0$ and $1$. Cantor showed that the "set" of decimals is actually "larger" than the set of whole numbers. It’s enough to give you a headache. This discovery was so controversial at the time that other mathematicians called him a "corrupter of youth" and a "scientific charlatan."
The Lemniscate in the Real World
The word "lemniscate" comes from the Latin lemniscatus, meaning "decorated with ribbons." In algebraic geometry, a lemniscate is a polar curve that looks exactly like our friend, the infinity symbol. Bernoulli described it in 1694. He was looking at it through the lens of fluid mechanics and geometry, totally separate from Wallis’s algebraic shorthand.

It’s interesting how two different fields—pure math and geometry—converged on the same visual. It suggests there’s something inherently "correct" about this shape. It feels balanced. It feels closed yet open.
Why We Are Obsessed With Wearing It
If you walk into any jewelry store today, you’ll find a silver infinity symbol necklace within ten seconds. Why? Because the symbol has shifted from a mathematical constant to a spiritual promise. In modern jewelry and tattoos, it represents:
- Eternal Love: The idea that a bond doesn't break just because circumstances change.
- Rebirth: Similar to the Ouroboros (the snake eating its own tail), it suggests that every end is just a new beginning.
- Empowerment: Many people use it to represent limitless potential. The idea that "I can do anything" because there are no bounds.
It’s a bit cliché now. Let’s be real. If you get an infinity tattoo, someone's going to make a joke about 2014 Tumblr. But who cares? The symbol carries weight because it’s a visual anchor. Life is chaotic and full of hard stops. The infinity symbol offers a tiny bit of visual defiance against the fact that we are all, eventually, going to run out of time.
The Ouroboros Connection
You can't talk about the meaning of the infinity symbol without mentioning the Ouroboros. This is the ancient Egyptian and Greek image of a serpent eating its own tail. It’s the ancestor of the infinity loop. While the modern version is clean and geometric, the Ouroboros is visceral. It represents the cyclical nature of the universe—creation out of destruction, life out of death.
Alchemy adopted this heavily. For an alchemist, the loop represented the "All is One." It was about the unity of matter and spirit. When you look at a modern infinity symbol, you’re looking at a sanitized, digitized version of an ancient dragon eating itself. That’s way cooler than a "best friends" charm, honestly.
Common Misconceptions and Errors
People often mix up infinity with the "Mobius Strip." They look similar, but they are fundamentally different things. A Mobius strip is a 3D object—a surface with only one side and one boundary. If you take a strip of paper, twist it once, and tape the ends together, you’ve made one. If you draw a line down the middle, you’ll eventually return to where you started without ever lifting your pen or crossing an edge.
While the infinity symbol is a 2D representation of a concept, the Mobius strip is a physical paradox. One is a sign; the other is a shape.

Another big mistake is thinking infinity means "everything." In math, that’s not true. A set can be infinite but very limited. For example, the set of all even numbers is infinite, but it contains zero odd numbers. It’s infinite, but it’s missing half of the "everything."
Tarot and the Occult
Check out a classic Rider-Waite Tarot deck. Look at "The Magician" card or the "Strength" card. See that little halo floating above their heads? It’s the infinity symbol. In this context, it’s called a magus.
It represents the divine connection between the spiritual and physical planes. In the Strength card, it shows that true power isn't about muscles; it's about the infinite endurance of the spirit. It’s a reminder that the person holding the card has access to energy that doesn't run dry. It turns the symbol into a battery.
The Psychology of the Loop
There’s a reason this symbol is used in "fidget" toys and relaxation exercises. Tracing a figure-eight pattern with your eyes or your finger has a calming effect on the nervous system. It’s a rhythmic, crossing-the-midline movement. Occupational therapists often use "Lazy 8s" to help kids with focus and coordination.
The infinity symbol literally helps bridge the left and right hemispheres of the brain. It’s not just a pretty shape; it’s a neurological reset button.
How to Use the Infinity Concept in Your Life
Maybe you aren't looking for a tattoo or a math degree. You can still use the logic of the infinity symbol to change your perspective.
First, stop thinking in "finite" terms about your skills. The "Growth Mindset" made famous by Carol Dweck is basically the infinity symbol applied to the human brain. Instead of saying "I'm not good at this," you realize that the potential to learn is an open loop.

Second, use it to frame your relationships. Not in the "we will be together forever" way—which is a lot of pressure—but in the sense of "reciprocity." The loop is about giving and receiving in a continuous flow. If the energy only goes one way, the loop breaks.
Lastly, acknowledge the "different sizes of infinity" in your own life. Some projects are big, some are small, but they all have their own internal depth. You don't have to do everything to do something that feels infinitely meaningful.
Practical Steps for Symbol Enthusiasts
If you're looking to incorporate this symbol into your space or life without it feeling like a 2010s throwback, look for the "Double Infinity." It’s two loops intertwined. It represents "interconnectedness"—the idea that my infinity and your infinity are tangled up together. It’s a bit more complex and visually interesting.
Alternatively, look into the "Infinity Heart." It’s a newer variation often used by the polyamory community to represent "infinite love" for multiple partners. It’s a great example of how symbols evolve to meet new cultural needs.
The infinity symbol isn't going anywhere. It survived the 17th-century math wars, the occult circles of the 19th century, and the mall kiosks of the 21st. It’s a permanent part of our visual language because it describes the one thing we can’t quite grasp: the fact that some things just don't end.
Whether you're using it to calculate the volume of a sphere or just trying to tell your mom you'll love her forever, the sideways eight is the ultimate shorthand for the human spirit's refusal to accept limits. Use it intentionally. Don't let it just be a piece of clipart. Remember that it represents a legacy of mathematicians who went half-mad trying to prove its existence and mystics who used it to explain the soul. That’s a lot of power for a little loop.
