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! ...

Have you ever watched a skateboarder do a crazy full spin in the air and heard someone call it a "360"? But wait, where does that giant number even come from? Why do we use 360 to measure one single spin? In this amazing episode of Maths is Not Boring, Mira and Finn uncover a mathematical secret that is over two thousand years old! We are traveling all the way back to ancient Babylon to meet the brilliant astronomers who first chopped the huge night sky into 360 tiny slices. Discover how the ...
Imagine building a pyramid entirely out of numbers! Start with a single '1' at the very top. The only rule to build the rest? Every number inside is just the two above it added together! It sounds incredibly simple, but this one tiny rule creates one of the most magical shapes in the universe: Pascal's triangle! Join Mira and Finn as they uncover the mind-bending secrets hiding inside this famous number pyramid. You'll find regular counting numbers, secret patterns used for setting up bowling...
Have you ever imagined building a snowman in the middle of July? That is exactly what could happen if we didn't have leap years! Join Mira and Finn as they uncover the mind-bending space secret behind February 29th. You will discover that a year isn't actually a neat 365 days long—it takes the Earth 365 and a quarter days to travel all the way around the Sun! Without that extra quarter of a day, our calendar would slowly drift away from the seasons until summer turned into winter.
Have you ever tried to measure something, only to find the number goes on forever? Join Mira and Finn as they uncover one of the biggest, wildest mysteries in the history of mathematics! Over two thousand years ago, a group of ancient Greek thinkers called the Pythagoreans believed the whole universe was built on neat, perfectly tidy fractions. But then, a man named Hippasus looked at a totally normal square and its diagonal line. When he tried to measure it, he discovered a wild, rebellious ...
Have you ever looked at a giant list of numbers and felt your brain turn to mush? You're not alone! A long time ago in 1854, a nurse named Florence Nightingale traveled to an army hospital in Scutari to help sick soldiers. But she quickly discovered a shocking secret: the dirty, crowded hospital was actually making soldiers sicker than the battles were!
