Maths for Kids / Maths is Not Boring: The Kids Maths Podcast

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!

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!

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!

Did you know there are "rebel numbers" hiding in the world right now that absolutely refuse to follow the rules?! Welcome to the wild, mind-bending world of prime numbers! A prime number is a special number that can only be divided evenly by itself and the number one—like 2, 3, 5, 7, and 11. They are the unbreakable building blocks of mathematics! Over two thousand years ago, a brilliant mathematician named Euclid proved an amazing secret: prime numbers never, ever run out. They go on for infinity! But here is the craziest part: nobody knows the pattern of where the next one will appear! In October 2024, computers found the largest known prime number, and it is so gigantic it has over 41 million digits! Today, we use these massive, unbreakable numbers as secret digital padlocks to keep our phone messages completely safe. Even insects use them! Discover how mysterious 13-year and 17-year cicadas use prime numbers to outsmart hungry predators in the wild. Join Mira and Finn as we unlock the greatest unsolved mystery in mathematics!

Have you ever played a game of cards like Go Fish or Snap? What if I told you that every time you shuffle a brand new deck of 52 cards, you are holding a tiny piece of history that has almost certainly never existed before in the universe?! It sounds like magic, but it is actually the incredible maths of permutations! Join Mira and Finn as they explore how ordinary playing cards can be ordered in more ways than there are atoms in our entire Milky Way galaxy. That is a massive number with 68 digits! We will also travel back to 1992 to meet a real-life magician-turned-mathematician named Persi Diaconis. He and his partner Dave Bayer proved that it takes exactly seven "riffle shuffles" to completely and perfectly mix up a pack of cards. You will learn how a giant, invisible factory of numbers makes possible combinations explode faster than you can count. Get ready to have your mind totally blown—the next time you shuffle a deck of cards, you will be holding a brand new, totally unique pattern right in the palms of your hands!

Have you ever tried counting as high as you possibly can? What happens if you never stop adding one? You get to infinity! But wait... did you know that forever actually comes in different sizes?! It sounds impossible, but it is completely true! Join Mira and Finn on a mind-bending adventure to the 1870s to meet a brilliant mathematician named Georg Cantor. He shocked the entire world by proving that some endless things are actually bigger than other endless things! We will explore a giant, glittering hall to see how numbers pair up perfectly, and check into the amazing Hilbert's Hotel—a massive, endless building that is always completely full, yet somehow always has room for one more guest! Even though people laughed at Cantor's bizarre discoveries, he proved that infinity isn't just out in deep space. It is hiding right inside your pencil case! Get ready to stretch your brain and discover why a tiny, one-inch pencil line holds more points than there are counting numbers in the universe. Tune in and find out why math is definitely not boring!

Have you ever wondered if someone in your classroom shares your exact birthday? It feels like it would take hundreds of kids to find a match, right? Well, get ready to have your mind blown! In this episode, Mira and Finn uncover the amazing mathematical secret known as the Birthday Paradox! It turns out, if you put just twenty-three people in a room, it is more likely than not that two of them will share a birthday. How can that be true when there are 365 days in a year?! We will learn how brilliant mathematician Richard von Mises published this incredible puzzle in 1939. You will discover why our brains trick us into counting individual people instead of invisible pairs, and how the number of chances explodes super fast! A room of 23 people actually makes 253 unique pairs! We will even find out how a football pitch has exactly 23 people on it at kickoff, and how computers use this exact same maths to keep your passwords safe online. Join us to find out how coincidences that feel like absolute magic are really just hidden chances!

Did you know that every single circle in the universe is hiding a secret, endless number? Join Mira and Finn on Maths is Not Boring as they uncover the wild and wondrous mystery of Pi! Whether it is a tiny coin in your pocket, a spinning bicycle wheel, or a giant planet floating in space, every circle shares the exact same mathematical magic. Travel all the way back to ancient Greece to meet a clever mathematician named Archimedes, who figured out how to trap this tricky number just by drawing shapes in the sand! But here is the most mind-bending part: the digits of Pi go on forever and ever without repeating. From 3.14 to over one hundred trillion digits discovered by modern supercomputers, this incredible number simply never stops! Discover why Pi isn't just in kitchen plates and clocks, but also in ripples on a pond and the spinning orbits of the stars. You will never look at a circle the same way again!
