À propos du podcast
A groundbreaking podcast for curious kids aged 4-12 that proves maths is anything but dull.
Join our fictional AI hosts Mira, a brilliant 9-year-old, and her younger brother Finn, age 7, as they set off on a journey into one great mathematical idea each episode. From numbers that never end and shapes with only one side to the strange rules of chance and the secret patterns in a snowflake, each episode uncovers an idea that is simple at its heart and extraordinary because it is everywhere - told in a way that actually makes sense to kids.
Nobody does sums here. Whether you're discovering why infinity comes in different sizes, how a shuffled pack of cards is almost certainly in an order no one has ever seen, why honeycombs are made of hexagons, where the number zero came from, or what makes a prime number special - Maths is Not Boring turns big ideas into stories that ignite curiosity and wonder, and gives kids one more clue to how the world works.
Because maths isn't a list of rules to learn. It's the most beautiful way anyone has ever found of seeing the world.
A note on why we use AI. For us, AI allows us to deliver learning at a scale and quality that previously would have been too expensive. If we make the odd technical error, or the sound goes a bit funny, bear with us, we’re trying our best. We hope you enjoy the show!

Did you know that every flat triangle hides a brilliant mathematical secret? Join Mira and Finn as they uncover the magic of triangles and the 180-degree rule! Grab a piece of paper, draw the wildest, weirdest triangle you can imagine, and cut it out. If you tear off the three corners and push their points together, something amazing happens. They lock together to form a perfectly straight line, every single time! A straight line is exactly a half-turn, or 180 degrees. This means the angles of a triangle share a strict budget that they can never, ever overspend! Discover the great Greek mathematician Euclid, who lived in the city of Alexandria around 300 BCE. He was the very first person to prove that this amazing rule is absolutely true for every flat triangle in the universe! You will learn how builders, architects, and map makers use this invisible geometry rule every single day to build roofs and navigate ships. But what happens if you draw a giant triangle on a curved globe like the Earth? Tune in to find out why this magical shape is anything but boring!What is optimal stopping?

Imagine you are walking down a huge, beautiful beach looking for the absolute best spot to build an epic sandcastle. But there is a massive catch! You can only walk forward, and once you pass a spot, you can never go back! How do you know when to stop and choose? If you pick too early, you might miss the perfect spot. If you wait too long, the best spot is already miles behind you! It feels like an impossible guessing game, but guess what? Maths has a secret superpower to solve it! It is called Optimal Stopping, and it will completely bend your brain! In this thrilling episode, Mira and Finn uncover the magical 37 percent rule. Made famous in 1960 by brilliant puzzle master Martin Gardner, this rule tells you exactly how long to look before making your big choice! Whether you are picking a giant scoop of ice cream, catching a massive wave to surf, or hunting for the best seat on a train, this amazing maths trick works perfectly.

Have you ever watched someone try to squeeze a giant, comfy sofa around a tight corner? It is tough! People yell "Pivot!", push, pull, and sometimes get totally stuck. But did you know this everyday annoyance is actually one of the most famous geometry puzzles in history? It's called the moving sofa problem! Back in 1966, a mathematician named Leo Moser wondered: what is the absolute biggest flat shape you can slide down a straight hallway and around a sharp right-angled corner? A simple square works, but smart mathematicians realized curves are even better! One mathematician even created a giant shape that looks exactly like a chunky old-fashioned telephone. Then, Joseph Gerver calculated a mind-bending sofa made of 18 perfectly stitched curves that spins and slides through a corner in a beautiful, twisting dance! But the wildest part? For over thirty years, nobody could prove if Gerver's shape was the absolute biggest possible one. It wasn't until 2024 that a young mathematician named Baek Jin-eon finally solved it, writing a brilliant proof over 100 pages long! Join Mira and Finn to uncover the brain-bending puzzle hiding in every hallway!What is an inverse?

Have you ever played the fast-paced, noisy card game Dobble? You flip over two round cards covered in tiny pictures, and everyone races to find the one matching symbol! But did you know there is a hidden mathematical secret inside that little metal tin? It's true! No matter how many times you shuffle the deck, ANY two cards you pick will always share exactly one matching picture. Never two, and never zero! How is that even possible? The secret isn't magic—it’s an incredible mind-bending puzzle called a finite projective plane! Back in the 1800s, long before the game came to shops in France in 2009, mathematicians discovered a special geometry world where lines behave completely differently. In this amazing secret map, every card is a line and every picture is a mathematical point! Join Mira and Finn as they uncover the invisible web holding your favorite game together!

Did you know a famous math rule was secretly discovered over a thousand years before the guy it’s named after was even born? Grab a piece of paper and draw a triangle with one perfectly square corner. Now, imagine attaching a square to all three sides. If you cut up the two smaller squares, they will fit perfectly inside the biggest square—with absolutely no leftovers! This magical balancing act works for every single right-angled triangle in the universe. It is called Pythagoras’ theorem, named after a Greek thinker from 500 BCE. But there's a massive twist! Archaeologists found an ancient clay tablet called Plimpton 322 made by Babylonian scribes in 1800 BCE. That means they knew this secret code way before Pythagoras! From ancient builders stretching knotted ropes to make perfect pyramids, to the makers of your flat-screen TV and phone map apps today, this secret mathematical puzzle is hiding everywhere.

Did you know that sometimes 11 plus 3 equals exactly 2?! It sounds impossible, but you actually use this crazy math every single day without even realizing it! Welcome to the mind-bending world of clock arithmetic! Instead of numbers going on forever in a boring straight line, what if they wrapped round and round in a circle? After 12 o'clock comes 1 again! Days of the week and months of the year do the exact same thing. In 1801, a brilliant 24-year-old mathematician from Germany named Carl Friedrich Gauss wrote a massive book proving that these spinning numbers follow their very own tidy rules. He called it modular arithmetic, and the secret star of the show is the "remainder"—the part left over after you make a full circle! Today, this same looping math isn't just for telling time. It is the secret superpower that checks barcodes at the grocery store and protects secret text messages on your phone! Join Mira and Finn as they spin into the amazing, endless loops of wrapping math!What is a weather forecast?

Have you ever looked at a weather app and seen a "70% chance of rain"? What does that actually mean? Most people think it means it will rain for 70% of the day, or that 70% of your city will get soaked. But that is entirely wrong! Join Mira and Finn as they uncover the mind-bending math behind predicting the weather! Our journey starts all the way back in London in 1861 with a brilliant sea captain named Robert FitzRoy, who once sailed the world with the famous scientist Charles Darwin. FitzRoy created some of the very first public weather forecasts to keep sailors safe from dangerous storms! Today, scientists use giant supercomputers to create dozens of different fake futures for tomorrow's weather. They let these futures race each other inside the computer! So, if your app says there is a 70% chance of rain, it means that out of ten identical futures, seven of them have rain falling right on your house! Grab your umbrella and get ready to hold a little piece of probability in your hand! It is a magical game of chance with the sky!What is a tangram?

Have you ever played with a puzzle that can turn into a crouching cat, a running person, or a tall sailing boat? Welcome to the magical world of tangrams! A tangram is a famous puzzle from China made of exactly seven pieces: five triangles, one square, and a slanted shape called a parallelogram. When an American sea captain brought these puzzles home in 1815, it started a massive craze across America and Europe. People were so obsessed that even the French Emperor Napoleon played with them while stranded on a lonely island! But here is the most amazing secret hiding inside those seven pieces: no matter what crazy shape you build, it will always cover the exact same amount of space on the table. In maths, this mind-bending trick is called "conservation of area"! Join Mira and Finn as they uncover the incredible history and hidden maths behind this shape-shifting puzzle. Grab your puzzle pieces and let's get building!What is Benford's Law?

The universe has a secret favorite number! Join Mira and Finn on Maths is Not Boring as they uncover the amazing mystery of Benford's Law! Our story starts all the way back in 1881, when an astronomer named Simon Newcomb noticed something super weird at the library. A heavy book of numbers was completely worn out and grubby on the pages starting with the number 1, but totally pristine on the pages starting with 9! Decades later, a physicist named Frank Benford tested 20,000 real-world numbers, from the lengths of rushing rivers to the populations of huge cities. He discovered that the number 1 shows up as the first digit a whopping 30 percent of the time! Discover how this magical math rule actually works, why growing towns get "stuck" on the number 1, and how real-life scientists use this invisible pattern as a secret lie detector to spot made-up numbers!What is a labyrinth?

Did you know that every time you fold a simple paper airplane or a beautiful paper crane, you are actually doing some seriously cool math? It’s true! For centuries, people folded paper just for fun, but in the 1980s, a Japanese physicist named Jun Maekawa discovered a secret rule hiding inside the paper. If you flatten out an origami shape, the creases always follow a strict mathematical code of upward "mountains" and downward "valleys" that always differ by exactly two! But that’s not all! A single sheet of paper can solve puzzles that are totally impossible with normal tools. For two thousand years, people tried to split an angle into three equal parts with just a ruler and compass. In 1837, mathematician Pierre Wantzel proved it was impossible—but guess what? A few clever paper folds can do it easily! These amazing origami rules aren't just for making fun shapes on your desk. They are so incredibly powerful that scientists use them to pack giant solar panels into rockets and send them into outer space!

Travel all the way back to the year 1637 to meet René Descartes, a brilliant French thinker who loved sleeping in until noon. Legend has it that while he was staring at his ceiling from his cozy bed, he watched a tiny fly crawl across the roof and wondered how to describe exactly where it was. His big idea? You only need two numbers—how far across, and how far up—to pin down any spot on a flat page! Discover how this one simple idea built a magical bridge between shapes and numbers, and how another clever thinker named Pierre de Fermat had the exact same idea at the same time. Tune in to find out how an invisible web of lines secretly runs our modern world!How did Julius Caesar write secret messages?
Imagine you are a Roman general holding a piece of parchment, but all the words are a completely jumbled mess! Did the messenger drop it in a puddle? No! You are holding a top-secret message locked by Julius …

Imagine you are a Roman general holding a piece of parchment, but all the words are a completely jumbled mess! Did the messenger drop it in a puddle? No! You are holding a top-secret message locked by Julius Caesar himself! Join Mira and Finn as we travel back two thousand years to Ancient Rome to uncover the amazing mathematical secret behind the famous Caesar shift. Discover how sliding the alphabet over by just three letters created a giant game of hide-and-seek between clever code-makers and code-breakers! We will find out how Caesar's great-nephew Augustus used his own sneaky cipher, and how this brilliant ancient trick started a race that lasted all the way to Alan Turing and the brilliant code-breakers at Bletchley Park during the Second World War. But the race isn't over yet! Did you know you use super-powered secret ciphers every single day? Find out how the exact same idea protects the text messages and video calls you make right now! Get ready to crack the code and discover the incredible math hiding right inside your pocket!What is a Reuleaux polygon?

Have you ever noticed that manhole covers on the street are almost always round? It turns out, this isn't just a random design choice—it is a life-saving piece of maths! If a manhole cover were square, it could accidentally tilt and slip diagonally right down the hole, crashing into the dark sewer below! But a circle is a special shape with "constant width." That means no matter which way you turn it, measure it, or tip it, it is exactly the same distance across. It can never fall in! But hold onto your hats, because circles aren't the only shapes with this math magic. In the 1870s, a German engineer named Franz Reuleaux discovered weird, bulging, curved-sided shapes that also have constant width! Even though they have corners, they can roll completely flat! Join Mira and Finn as they uncover the incredible secrets of Reuleaux polygons. You will even learn how the bumpy, seven-sided British fifty pence coin tricks vending machines into thinking it is perfectly round! Get ready to look at the streets and your piggy bank in a totally new way!What is estimation?
Have you ever tried to guess how many sweets are in a giant glass jar? It is super tricky! Usually, if you ask just one person, their guess is way off. But what if you asked hundreds of people and put all their …

Have you ever tried to guess how many sweets are in a giant glass jar? It is super tricky! Usually, if you ask just one person, their guess is way off. But what if you asked hundreds of people and put all their wrong guesses together? Could they magically find the exact right answer? Join Mira and Finn on a time-traveling trip back to a bustling country fair in Plymouth, England, in the year 1906! Right in the middle of the fair was a massive, heavy ox. A curious scientist named Francis Galton watched as 787 people paid a tiny coin to guess the giant animal's weight. Some guesses were way too high, and some were way too low. But when Galton lined up every single piece of cardboard and found the exact middle guess, something unbelievable happened! The crowd’s middle guess was 1,207 pounds, missing the real weight by less than one percent! Discover the amazing mathematical magic of estimation, learn what a "median" is, and find out why the "wisdom of the crowd" means that we are always smarter when we work together! You will be a master at guessing games!
