What is a tessellation?

About this episode

Have you ever looked closely at a bathroom floor, a brick wall, or a beehive's honeycomb? They are made of shapes that fit perfectly together with zero gaps! This mathematical magic is called a tessellation! For decades, mathematicians wondered about an impossible puzzle: could just one single shape cover an endless floor without the pattern ever repeating itself? They called this mystery the "einstein" problem (which means "one stone" in German). Many experts thought it was completely impossible! But in 2022, a retired print technician in Yorkshire named David Smith made a mind-blowing discovery. He wasn't using giant supercomputers—he was just having fun cutting shapes out of cardboard on his kitchen table! David discovered a wild, 13-sided shape he called "the hat" that solves the puzzle perfectly. You can lay these little hats down forever, and the swirling pattern will never, ever repeat! Join Mira and Finn on Maths is Not Boring as they explore this incredible story of curiosity, cardboard shapes, and infinite patterns! You will never look at a tiled floor or a jigsaw puzzle the same way again!

What is the equals sign?

About this episode

Have you ever wondered where the equals sign came from? Most of us think those two little horizontal lines just mean "ta-da, the answer comes next!" But the true story is much bigger, and it starts all the way back in 1557! Join Mira and Finn as they travel back in time to meet Robert Recorde, a brilliant Welsh doctor and mathematician. Robert was writing a magnificent book called The Whetstone of Witte, but he got completely fed up with writing the words "is equal to" over and over again with his scratchy feather quill. His solution? He drew two giant parallel lines! Why? Because as he put it, no two things can be more equal! But here is the most amazing secret: the equals sign doesn't actually mean "calculate this now." It is actually a picture of perfect balance! Imagine a bright red see-saw hovering perfectly flat, or a fair trade of playing cards with your friends. Discover how this simple shortcut totally changed the world of math, and why Robert’s clever new symbol was surprisingly slow to catch on. Get ready to see tiny see-saws everywhere!

What is the Law of Large Numbers?

About this episode

Have you ever flipped a coin and wondered if you could guess what it would land on? If you toss a coin once, it’s completely wild—anything could happen! But what if you tossed that same coin ten thousand times? During World War II, a mathematician named John Kerrich was stuck in a camp in Denmark with a lot of time on his hands. So, he and his friend decided to play the longest game ever! They flipped a coin 10,000 times and wrote down every single result. Did they get exactly 5,000 heads and 5,000 tails? Not quite, but they got amazingly close with 5,067 heads! This incredible coin-flipping experiment proved a mathematical secret called the Law of Large Numbers! First discovered by a man named Jacob Bernoulli in the 1700s, this amazing rule shows us that even when one event is totally unpredictable, a huge number of events will always settle down into a clear pattern. Join Mira and Finn as they explore how this invisible rule turns wild chaos into steady order!

What is a fractal?

About this episode

Have you ever wondered how long the coast of Britain is? Well, the answer depends entirely on the size of your ruler! If you use a giant ruler, you'll get one number. But if you use a tiny ruler, you have to measure every single zig-zag, cove, and rock, making the coast seem magically longer! This wild, mind-bending trick of nature is all about something called a fractal. Join Mira and Finn as they zoom into the infinite, never-ending world of fractals! We'll solve the mystery of why Spain and Portugal got completely different numbers when they measured the exact same border. You'll also learn how a brilliant mathematician named Helge von Koch drew a special snowflake whose edge goes on forever, but still fits perfectly inside a simple circle! Fractals aren't just crazy puzzles—they are hiding all around us in the real world. From zooming in on pointy Romanesco broccoli and branching ferns, to cracking lightning bolts and the magical computer-animated trees in your favorite movies! The closer you look, the more detail appears. Get ready to never look at nature the same way again!

What is place value?

About this episode

Have you ever wondered why we count in tens? Look down at your hands—you are holding the answer! Because we have ten fingers, most of the world uses a magical mathematical superpower called "place value" built all around the number ten. But not everyone did it this way! Did you know the ancient Maya counted in twenties because they used their toes, too? Or that the ancient Babylonians counted in sixties, which is exactly why we still have 60 seconds in a minute today? In this mind-expanding episode of Maths is Not Boring, Mira and Finn uncover the greatest trick in the universe: the number slide! Discover how a brilliant system born in ancient India, carved onto shiny copper plates, lets us write every single number that will ever exist using just ten simple shapes. Plus, find out why the number zero is the ultimate heroic placeholder! Join us to see how a simple step to the left turns a tiny one into a massive trillion, and why you will never look at a video game scoreboard the same way again!

What is the fourth dimension?

About this episode

Imagine a whole universe completely flat like a piece of paper! There is no "up" and no "down"—just forwards, backwards, left, and right. In 1884, a headmaster named Edwin Abbott Abbott wrote a mind-bending story called Flatland about this exact idea! The people living in Flatland are flat shapes: triangles, circles, and a very confused square. Because they are totally flat, they can only ever see each other's edges as straight lines! But what happens when a solid, 3D sphere from our world visits Flatland? To the square, it looks like pure magic! A tiny dot appears out of nowhere, grows into a giant circle, shrinks, and then completely vanishes as the ball passes straight through the paper! The sphere even has to pull the square out of his universe to show him what "up" really means! Join Mira and Finn as they explore this incredible story and uncover a massive mathematical secret. Discover how scientists use Flatland to imagine a mind-blowing fourth dimension and learn what the shadow of a 4D tesseract looks like! Get ready to look at the universe in a completely different way!

What is the Pigeonhole Principle?

About this episode

Did you know there are definitely two people in London right now with the EXACT same number of hairs on their heads? And nobody even had to count them to figure it out! This mind-bending math magic is called the Pigeonhole Principle. It is super simple: imagine you have four sleepy pigeons, but only three wooden boxes for them to sleep in. No matter what, at least one pigeon is going to have to share a box! That simple idea is actually a mathematical superpower, perfected by a German mathematician named Peter Gustav Lejeune Dirichlet in 1834 (though people in France were using it for hair puzzles way back in 1622!). Join Mira and Finn as they use this awesome rule to uncover amazing hidden secrets about the world. Find out why any group of 13 people MUST have two people with the same birthday month, why pulling five playing cards always gives you a matching suit, and how this idea even works for counting leaves on trees! Get ready for a mathematical adventure!

What is the Monty Hall problem?

About this episode

Imagine you are standing on a brightly lit game show stage! Three colorful doors are in front of you. Behind one is a shiny new car, but behind the other two... are live, chewing goats! You pick a door. Suddenly, the host opens a different door to reveal a goat! He smiles and asks: "Do you want to stick with your first choice, or switch?" What would you do? Most people think it’s a fifty-fifty chance and doesn't matter, but they are WRONG! In 1990, a puzzle genius named Marilyn vos Savant wrote that switching actually doubles your chances of winning! When she shared this secret, thousands of people—even math professors—wrote angry letters telling her she was making a huge mistake! But guess what? She was completely right! Even the brilliant mathematician Paul Erdős didn't believe it until he saw a computer play the game thousands of times. Tune in to find out how a simple clue can completely change your chances, and learn the mind-bending math secret behind the famous Monty Hall problem!

What was the Seven Bridges of Königsberg?

About this episode

Imagine trying to go for a sunny Sunday walk, only to discover the path is mathematically impossible! In 1735, the beautiful city of Königsberg had two huge islands sitting right in the middle of a wide river, connected to the rest of the town by exactly seven bridges. The townspeople made up a massive puzzle: could anyone walk across all seven bridges exactly once without ever crossing the same one twice? People tried for years, wandering around and tracing maps, but everyone got stuck! It wasn't because they were bad at directions—it was because of math! A brilliant young mathematician named Leonhard Euler decided to solve the mystery. Instead of walking the bridges himself, he erased the entire city from his map and replaced the land and bridges with simple dots and lines. By inventing the world's very first mathematical network, he proved the famous walk couldn't be done! Join Mira and Finn on Maths is Not Boring as they uncover how Euler’s amazing join-the-dots trick gave us the amazing graph theory used to power map apps and the entire internet today!

What is exponential growth?

About this episode

Can you fold a normal piece of paper enough times to reach the Moon? It sounds completely impossible, but if you could fold a single sheet of paper just 42 times, the stack would explode past the clouds, past the satellites, and crash right into the Moon! How? It is all thanks to a math superpower called exponential growth! In this mind-blowing episode, Mira and Finn uncover how doubling something over and over makes it grow faster than you can even imagine. You will hear the incredible true story of a California high schooler who smashed a world record by folding a massive, 4,000-foot piece of tissue paper 12 times in a shopping mall! Plus, discover an ancient legend about a tricky chessboard, a greedy king, and a pile of rice bigger than Mount Everest. We will even dive into a sneaky riddle about a pond full of lily pads that will totally trick your brain! Get ready to have your mind blown by the magic of doubling!

What is zero?

About this episode

Have you ever tried to count... absolutely nothing? For thousands of years, humans counted sheep, gold coins, and days, but they had absolutely no number for zero! If you had three apples and ate them all, you just had an empty hand. But as math got more complicated, people realized they needed a way to hold empty spaces open so numbers like 15 wouldn't accidentally get mixed up with 105! Ancient civilizations like the Babylonians and the Maya invented clever placeholders to fix this—the Maya even used a beautifully carved picture of an empty seashell! But it wasn't until the year 628 CE in India that a brilliant mathematician named Brahmagupta gave zero its very own superpowers. He figured out that zero wasn't just a blank space; it was a real number with magical rules! If you add it, nothing changes, but if you multiply by it, everything vanishes! Poof! Join Mira and Finn as they trace the incredible journey of zero from ancient India to Europe with the help of a man named Fibonacci. Discover how the invention of nothing completely changed the world!

About this episode

Have you ever looked closely at a snowflake landing on your mitten and wondered why it looks like a perfect little star? Join Mira and Finn as they uncover the amazing, invisible rules of the universe! In this mind-bending episode, you will discover the magical math of symmetry—the reason why spinning a snowflake, flipping a butterfly's wing, or sliding a honeycomb leaves them looking exactly the same! But symmetry isn't just a cool trick of shapes. You will travel back in time to 1915 to meet Emmy Noether, a brilliant mathematician who solved a massive puzzle that even stumped Albert Einstein. She proved that every time you see symmetry in nature, the universe is actually hiding a secret law of physics! From water molecules shaped like tiny Mickey Mouse heads freezing into perfect hexagons, to bouncing balls traveling forward in time, get ready to see the world in a whole new way. Math has never been this beautiful!

What is a Mobius strip?

About this episode

Have you ever seen a shape with only one side? It sounds completely impossible, right? Everything in the world has a top and a bottom, or an inside and an outside! But in 1858, a German mathematician named August Ferdinand Möbius discovered a shape that breaks all the rules! By taking a simple strip of paper, giving it a single half-twist, and taping the ends together, he created the mind-bending Möbius strip! If a tiny ant walked along this loop, it would travel over the entire surface and end up exactly where it started without ever crossing an edge! This single twist opened the door to a wild new kind of maths called topology, where shapes can stretch and bend—meaning a doughnut and a coffee mug count as the exact same shape! The coolest part? Möbius strips are hiding everywhere in our everyday world! You can find them in the twisting arrows of the recycling symbol, heavy-duty factory conveyor belts, and even wild upside-down roller coasters! Join Mira and Finn as they explore how one little twist can completely change the universe!
