The Year Mathematics Surprised Everyone: 2025's Greatest Discoveries
We live in an age where a teenager with internet access can outpace professors with decades of experience. Where mathematicians discover new types of infinity that make our heads spin. Where shapes exist that seem to break the rules of physics itself.
2025 was that kind of year for mathematics.
Let's break it down together.
How Did a 17-Year-Old Solve What Experts Couldn't?
The Girl From the Bahamas Who Changed Everything
Hannah Cairo grew up homeschooled in the Bahamas. She learned mathematics by watching Khan Academy videos and devouring every resource she could find online. The isolation was crushing. "There was this inescapable sameness," she shared. "No matter what I did, I was in the same place doing mostly the same things. I was very isolated, and nothing I could do could really change that".
But here's the beautiful twist—mathematics became her escape hatch.
For Cairo, math wasn't homework. It was freedom. A "world of ideas that I can explore on my own," she called it. Think about that for a moment. While most teenagers scroll through social media, Cairo was wandering through abstract mathematical universes.
The 40-Year-Old Mystery She Cracked
When Cairo moved to California and started taking graduate-level classes at UC Berkeley, she stumbled upon a conjecture about the behavior of functions in harmonic analysis. This problem had stumped mathematicians for four decades.
After months of persistent work, she did something remarkable. She built a counterexample—a specific case that proved the conjecture wrong. Experienced mathematicians had missed it for 40 years.
Why could she see what others couldn't?
Fresh eyes matter. Sometimes the assumptions that guide experts also blind them. Cairo approached the problem without decades of ingrained thinking. She questioned what others took for granted.
That's often what success in math is all about.
💡 Key Takeaway
Mathematics, at its core, is an art. Like painters or musicians, mathematicians create and explore new worlds. They test, and then push past, the limits of their imagination.
What Are the Two New Infinities Scientists Found?
Infinity Isn't What You Think It Is
Here's something that might break your brain a little: there's not just one infinity. There are many.
Mathematicians have known since the 1870s that infinity comes in different sizes. The set of whole numbers (0, 1, 2, 3...) is the same size as the set of fractions. But it's smaller than the set of real numbers .
Wait, what?
Yes. Some infinities are bigger than others. And beyond these familiar types, there's a whole zoo of larger infinities with names like "strong" and "supercompact" that are nearly impossible to describe The 2025 Discovery That Shook Mathematics
In 2025, a team of mathematicians invented two entirely new types of infinity. And here's the kicker—these new infinities don't behave the way anyone expected.
This matters because it speaks to a deeper question: Is the mathematical universe mostly ordered, something we can comprehend? Or is it hopelessly chaotic?
In the 1930s, Kurt Gödel proved something unsettling. The mathematical universe is fundamentally unknowable in its entirety. There are true statements that can never be proved. But how close can we get to understanding it? The different types of infinities help mathematicians test their limits.
If these new infinities are real and properly understood, they suggest something profound. The mathematical universe might be full of mysteries and monsters we haven't even glimpsed yet.
Why Did the "Ten Martini Problem" Take 20 Years to Perfect?
When Physics Meets Pure Mathematics
Picture this: electrons in a crystal near a magnet. Their energy levels don't form a smooth spectrum. Instead, they create a pattern called the Cantor set—a famous fractal that looks like dust spread across a line "ten martini problem" asked whether this strange fractal pattern always appears in solutions to Schrödinger's equation for these electrons. The problem was so difficult that a mathematician literally offered 10 martinis to whoever could solve it.
A Proof That Needed Fixing
The problem was first solved in 2004. But one of the authors, Svetlana Jitomirskaya, wasn't satisfied. The original proof "was a patchwork quilt, each square stitched out of distinct arguments" It couldn't be applied to more general, realistic situations.
Twenty years later, Jitomirskaya returned to the problem. She and her colleagues produced a new, more powerful proof—one that cements this strange connection between number theory and quantum physics as something deep and true
🦋 The Butterfly Connection
The story involves graphs that resemble butterfly wings, a calculator named Rumpelstilzchen, and Douglas Hofstadter's delightful book Gödel, Escher, Bach. Mathematics has a way of connecting the strangest things.
This is what Eugene Wigner called the "unreasonable effectiveness of mathematics." Abstract math often mysteriously provides the perfect language for understanding the natural world
Can a Shape Really Not Pass Through Itself?
The Strange World of Convex Polyhedra
Here's a fact that sounds impossible: for most convex polyhedra (shapes with flat sides and no indentations, like cubes or dodecahedra), you can bore a straight tunnel through them big enough for an identical copy to pass through .
A cube can fit through a smaller hole in itself. A tetrahedron can slip through a tunnel in its twin. It seems absurd, but it's mathematically true.
The Noperthedron: A Shape That Breaks the Rule
For centuries, mathematicians searched for an exception. A convex polyhedron that couldn't pass through itself. Something without this so-called "Rupert property."
In 2025, they finally found it.
Meet the Noperthedron—a shape with 90 vertices and 152 faces . No matter how you try, you cannot bore a straight tunnel through it that allows another copy to pass.
The Noperthedron
90 Vertices • 152 Faces • First of its kind
The One-Sided Tetrahedron
And if that wasn't enough, 2025 also brought us a tetrahedron that can only rest on one of its four triangular sides. Place it on any other side, and it flips to its stable positionI didn't expect more work to come out on tetrahedra," one researcher admitted . But that's mathematics for you. There's always more to learn, even about things we think we fully understand.
Why Is Proving a Number Irrational So Difficult?
The Basic Question That Haunted Mathematicians for Decades
Most numbers are irrational. They can't be written as a fraction of two whole numbers. Pi (π) is irrational. So is the square root of 2. So is e, the base of natural logarithms.
But here's the catch: proving a specific number is irrational is incredibly hard.
Yes, you read that correctly. We know π is irrational. We know e is irrational. But we still can't prove that π + e is irrational.
Chaos in the Lecture Hall
These proofs have been rare—and sometimes dramatic. When one mathematician announced his irrationality proof, "the lecture quickly descended into pandemonium. Mathematicians greeted his assertions with hoots of laughter, called out to friends across the room, and threw paper airplanes" 2025, mathematicians developed new techniques that let them prove irrationality for a whole slew of important numbers. "After so many years spent peering through the fog," one expert noted, "mathematicians are finally starting to clearly discern an array of landmarks in one of their most fundamental landscapes—the number line"
How Maryam Mirzakhani's Legacy Lives On
A Revolutionary Who Left Too Soon
Maryam Mirzakhani transformed hyperbolic geometry as a graduate student. She developed groundbreaking techniques for understanding mind-bending surfaces that appear throughout math and physics. In 2014, she became the first woman to win the Fields Medal—mathematics' highest honor .
She died at age 40, before she could fully explore what she had discovered.
The Women Carrying Her Torch
Two mathematicians, Nalini Anantharaman and Laura Monk, have picked up where Mirzakhani left off. Monk acted as an archaeologist, excavating all of Mirzakhani's papers to develop an intimate understanding of her work—and, through her work, of her as a person .
What's beautiful about these stories is how human they are.
Mirzakhani had a deep passion for literature and once dreamed of being a writer. Anantharaman trained as a classical pianist and seriously considered pursuing music instead of math.
✨ The Humanity Behind the Equations
Mathematics doesn't happen in a vacuum. It's influenced by philosophies of thought and, ultimately, people. Sometimes revolutionaries come on the scene, guiding how mathematicians think about a particular field for generations .
What Does All This Mean for You?
You don't need to be a mathematician to appreciate these discoveries. They remind us of something powerful:
- Youth isn't a barrier. Hannah Cairo proved that isolation and limited resources don't have to stop you from changing the world.
- Persistence pays off. Jitomirskaya spent 20 years perfecting a proof because "good enough" wasn't good enough for her.
- There's always more to learn. Even basic concepts like shapes and numbers hold secrets we haven't uncovered.
- Legacy matters. Mirzakhani's work continues to inspire, even years after her passing.
Mathematics shows us that the universe is stranger, more beautiful, and more surprising than we ever imagined. And every single one of us can participate in that wonder.
