In some significant sense, a ball is the simplest of these shapes. It was groundbreaking, yet modest. Perelman rejected both. He said his work was for the benefit of mathematics, not personal gain, and also that Hamilton, who laid the foundations for his proof, was at least as deserving of the prizes.
Pierre de Fermat was a 17th-century French lawyer and mathematician. He made claims without proving them, leaving them to be proven by other mathematicians decades, or even centuries, later. These are known as the Pythagorean Triples, like 3,4,5 and 5,12, Fermat famously wrote the Last Theorem by hand in the margin of a textbook, along with the comment that he had a proof, but could not fit it in the margin.
For centuries, the math world has been left wondering if Fermat really had a valid proof in mind. For his efforts, Wiles was knighted by Queen Elizabeth II and was awarded a unique honorary plaque in lieu of the Fields Medal, since he was just above the official age cutoff to receive a Fields Medal. Groups can be finite or infinite, and if you want to know what groups of a particular size n look like, it can get very complicated depending on your choice of n. When n hits 4, there are two possibilities.
Naturally, mathematicians wanted a comprehensive list of all possible groups for any given size. The complete list took decades to finish conclusively, because of the difficulties in being sure that it was indeed complete. Arguably the greatest mathematical project of the 20th century, the classification of finite simple groups was orchestrated by Harvard mathematician Daniel Gorenstein, who in laid out the immensely complicated plan. By , the work was nearly done, but spanned so many pages and publications that it was unthinkable for one person to peer review.
Part by part, the many facets of the proof were eventually checked and the completeness of the classification was confirmed. By the s, the proof was widely accepted. Subsequent efforts were made to streamline the titanic proof to more manageable levels, and that project is still ongoing today.
Grab any map and four crayons. The fact that any map can be colored with five colors—the Five Color Theorem —was proven in the 19th century. But getting that down to four took until Two mathematicians at the University of Illinois, Urbana-Champaign, Kenneth Appel and Wolfgang Hakan, found a way to reduce the proof to a large, finite number of cases.
With computer assistance, they exhaustively checked the nearly 2, cases, and ended up with an unprecedented style of proof. It has since become far more common for proofs to have computer-verified parts, but Appel and Hakan blazed the trail. He proved the foundational theorems about cardinality, which modern day math majors tend to learn in their Discrete Math classes.
Now, the real numbers are larger, but are they the second infinite size? And if CH is false, then there is at least one size in between. CH has been proven independent, relative to the baseline axioms of math. It can be true, and no logical contradictions follow, but it can also be false, and no logical contradictions will follow. You may have heard of the Axiom of Choice, another independent statement. The proof of this outcome spanned decades and, naturally, split into two major parts: the proof that CH is consistent, and the proof that the negation of CH is consistent.
Think through every case to see why this is an example of a true, but unprovable statement. On the other extreme, if it did have a proof, then that proof would prove it true … making it true that it has no proof, which is contradictory, killing this case.
Yeah, our heads are spinning, too. Imagine Amanda and Bob each have a set of mathematical axioms—baseline math rules—in mind. There are plenty of theorems about prime numbers. One of the simplest facts—that there are infinitely many prime numbers—can even be adorably fit into haiku form. The Prime Number Theorem is more subtle; it describes the distribution of prime numbers along the number line.
Since then, the proof has been a popular target for rewrites, enjoying many cosmetic revisions and simplifications. But due to the infinite nature of the sequence of numbers, it has so far been impossible to prove for definite.
The conjecture has spawned a novel by Apostolos Doxiadis, Uncle Petrov and the Goldbach Conjecture, and has been puzzled over for centuries. But when it comes to the most significant, unproven theorem, most agree that it is the Riemann Hypothesis, which was posed by the German mathematician Berhard Riemann in Moreso than the Goldbach conjecture, this is considered hugely important, because of the range of implications that would follow if it was proven, rather than just being a hypothesis.
But not to Mirzakhani. She has a strong geometric intuition. So far, so impossible to understand. But Professor Lyon said his the area builds on a field that has had a huge impact on everything from mobile phones to the stock market.
The first in a pair of twin primes is, with one exception, always 1 less than a multiple of 6. And so the second twin prime is always 1 more than a multiple of 6. You can understand why, if you're ready to follow a bit of heady Number Theory. All primes after 2 are odd. Even numbers are always 0, 2, or 4 more than a multiple of 6, while odd numbers are always 1, 3, or 5 more than a multiple of 6. Well, one of those three possibilities for odd numbers causes an issue. If a number is 3 more than a multiple of 6, then it has a factor of 3.
Having a factor of 3 means a number isn't prime with the sole exception of 3 itself. And that's why every third odd number can't be prime. How's your head after that paragraph? Now imagine the headaches of everyone who has tried to solve this problem in the last years. The good news is that we've made some promising progress in the last decade. Mathematicians have managed to tackle closer and closer versions of the Twin Prime Conjecture. This was their idea: Trouble proving there are infinitely many primes with a difference of 2?
How about proving there are infinitely many primes with a difference of 70,,? For the last six years, mathematicians have been improving that number in Zhang's proof, from millions down to hundreds. Taking it down all the way to 2 will be the solution to the Twin Prime Conjecture. The closest we've come —given some subtle technical assumptions—is 6.
Time will tell if the last step from 6 to 2 is right around the corner, or if that last part will challenge mathematicians for decades longer. Today's mathematicians would probably agree that the Riemann Hypothesis is the most significant open problem in all of math. It has implications deep into various branches of math, but it's also simple enough that we can explain the basic idea right here.
For each s, this function gives an infinite sum, which takes some basic calculus to approach for even the simplest values of s. So tricky, in fact, that it's become the ultimate math question. The hypothesis is that the behavior continues along that line infinitely. The Hypothesis and the zeta function come from German mathematician Bernhard Riemann, who described them in Riemann developed them while studying prime numbers and their distribution. Our understanding of prime numbers has flourished in the years since, and Riemann would never have imagined the power of supercomputers.
But lacking a solution to the Riemann Hypothesis is a major setback. If the Riemann Hypothesis were solved tomorrow, it would unlock an avalanche of further progress. It would be huge news throughout the subjects of Number Theory and Analysis.
Until then, the Riemann Hypothesis remains one of the largest dams to the river of math research. The Birch and Swinnerton-Dyer Conjecture is another of the six unsolved Millennium Prize Problems, and it's the only other one we can remotely describe in plain English. This Conjecture involves the math topic known as Elliptic Curves. When we recently wrote about the toughest math problems that have been solved , we mentioned one of the greatest achievements in 20th-century math: the solution to Fermat's Last Theorem.
Sir Andrew Wiles solved it using Elliptic Curves. So, you could call this a very powerful new branch of math. In a nutshell, an elliptic curve is a special kind of function. It turns out functions like this have certain properties that cast insight into math topics like Algebra and Number Theory. British mathematicians Bryan Birch and Peter Swinnerton-Dyer developed their conjecture in the s. Its exact statement is very technical, and has evolved over the years. One of the main stewards of this evolution has been none other than Wiles.
To see its current status and complexity, check out this famous update by Wells in A broad category of problems in math are called the Sphere Packing Problems. They range from pure math to practical applications, generally putting math terminology to the idea of stacking many spheres in a given space, like fruit at the grocery store. Some questions in this study have full solutions, while some simple ones leave us stumped, like the Kissing Number Problem.
Nothing tricky. A packed bunch of spheres will have an average kissing number, which helps mathematically describe the situation. But a basic question about the kissing number stands unanswered. First, a note on dimensions. The x-axis and y-axis show the two dimensions of a coordinate plane. A 1-dimensional thing is a line, and 2-dimensional thing is a plane. For these low numbers, mathematicians have proven the maximum possible kissing number for spheres of that many dimensions.
Beyond 3 dimensions, the Kissing Problem is mostly unsolved. Mathematicians have slowly whittled the possibilities to fairly narrow ranges for up to 24 dimensions, with a few exactly known, as you can see on this chart. For larger numbers, or a general form, the problem is wide open. There are several hurdles to a full solution, including computational limitations. So expect incremental progress on this problem for years to come.
The simplest version of the Unknotting Problem has been solved, so there's already some success with this story. Solving the full version of the problem will be an even bigger triumph. You probably haven't heard of the math subject Knot Theory. It's taught in virtually no high schools, and few colleges. The idea is to try and apply formal math ideas, like proofs, to knots, like … well, what you tie your shoes with.
For example, you might know how to tie a "square knot" and a "granny knot. But can you prove that those knots are different? Well, knot theorists can. Knot theorists" holy grail problem was an algorithm to identify if some tangled mess is truly knotted, or if it can be disentangled to nothing. The cool news is that this has been accomplished!
Several computer algorithms for this have been written in the last 20 years, and some of them even animate the process. But the Unknotting Problem remains computational. In technical terms, it's known that the Unknotting Problem is in NP, while we don't know if it's in P. That roughly means that we know our algorithms are capable of unknotting knots of any complexity, but that as they get more complicated, it starts to take an impossibly long time.
For now. If someone comes up with an algorithm that can unknot any knot in what's called polynomial time, that will put the Unknotting Problem fully to rest. On the flip side, someone could prove that isn't possible, and that the Unknotting Problem's computational intensity is unavoidably profound. Eventually, we'll find out. If you've never heard of Large Cardinals , get ready to learn.
In the late 19th century, a German mathematician named Georg Cantor figured out that infinity comes in different sizes. Some infinite sets truly have more elements than others in a deep mathematical way, and Cantor proved it. That's a Hebrew letter aleph; it reads as "aleph-zero. But the reals aren't that big; we're just getting started on the infinite sizes. For the really big stuff, mathematicians keep discovering larger and larger sizes, or what we call Large Cardinals.
But when it comes to the most significant, unproven theorem, most agree that it is the Riemann Hypothesis, which was posed by the German mathematician Berhard Riemann in Moreso than the Goldbach conjecture, this is considered hugely important, because of the range of implications that would follow if it was proven, rather than just being a hypothesis. But not to Mirzakhani. She has a strong geometric intuition.
So far, so impossible to understand. But Professor Lyon said his the area builds on a field that has had a huge impact on everything from mobile phones to the stock market. And experts have even speculated that his work could shed some light on another of those so-far unsolvable problems — the Navier Stokes problem, which is one of six remaining unsolved Millennium Prize Problems, which include the Riemann hypothesis.
But then again, not all mathematicians are in it for the glory.
