This series explains math, not as it is taught in school, but as a mysterious construction of the human mind that is present in our culture, our thinking and our everyday life! Discover new landscapes, exhilarating stories and great mathematicians.

Discover new landscapes, paradoxes, twists and turns, great mathematicians...and learn a few new words!

3 Knights - total losers - explore the confines of the known world, because their King has given them a mission: “Take a hike and try to find me”. In fact, the King wants to get rid of them because of their supreme stupidity.

On their journey, they travel across foreign territories and confront the enemies living in these hostile regions! At the end of the season, the 3 Knights, who will have braved many dangers and killed all baddies, will make an incredible discover: they have indeed found the King.

Why so many small numbers? Uncover the secret of the supermarket with Benford's Law.

The starting point of this episode of our short trips in the land of math: the trivial setting of a supermarket where a vast mathematical plot seems to be unfolding. Thanks to Benford's law, we will discover two ways of measuring the world and another way of seeing things.

The Monty Hall paradox, named after a game show from the 60s, concerns the way in which information acquired during the course of a game modifies (or not) the winning statistics.

Theoretically solved, the question is so disturbing to our worldview that it continues to be the subject of passionate debate to this day.

The Game of Life allows us to understand how a complex system can emerge from something simple.

On the program of this journey: the Game of Life. A game indeed, but one that allows us to better understand how a complex system can emerge from something simpler. This is called "emergence" and the story is somewhat reminiscent of our Universe. We will also meet different profiles of mathematicians, one of whom is very playful!

Statistics seem, almost by their very nature, to convey a positivist message. They are, in fact, a formidable tool in the attempt to master the complexity of the real world...

But numerous "biases" threaten any discourse that refers to them without care: an over-simplistic reading of the figures can lead us - for example - to confuse correlation with causation... And more complex phenomena (notably Simpson's paradox) can distort conclusions that seem objective.

In this episode of our short trips to the land of math, we will learn that Infinity exists in several sizes.

In this episode of our short trips in the land of math, we set course for the Infinite. And even beyond, because infinity exists in several sizes. Yes, it does. Vertiginous lands where Georg Kantor and his theory of sets will give us a serious help to find our way.

For centuries, geometry was based on Euclid's postulates, which seemed eternal and irrevocable.

However, one of the postulates (the fifth) has always seemed "a little less natural" than the others, and hundreds of mathematicians have tried in vain to do without it by deducing it from the other postulates. In the mid-19th century, Bernhard Riemann came up with a novel idea: let's imagine it's false! This was the birth of "non-Euclidean geometries", which would later have major applications in physics.

A tessellation is a way of covering a plane with a repeating pattern... Basically, it's like creating wallpaper.

In 1975, Marjorie Rice (1923- 2017), a mother and amateur mathematician, read an article by Martin Gardner in Scientific American that listed ALL possible "pentagonal tessellations" in the plane. A mathematician had just proved that the list was complete. Except that Marjorie, working alone at home, found 4 new ones... The theorem was wrong!

A dive into the heart of motion to understand from a mathematical point of view what speed means.

The starting point of this episode of our short trips in the land of math: Zeno's paradox. Or is speed only a series of immobile moments? Thanks to Newton and Leibniz, the rivals of the derivative, we will discover - without hurrying - the infinitesimal and differential calculus. And how, behind all movement, there is a fixed point.

The question is how to make a network that is both "economical" and "robust" without taking up too much space.

This is a theoretical question worked on by the great Russian mathematician Andrey Kolmogorov (1903-1987). But this theoretical question also conditions the way in which we can build a computer network or... a human brain: to be intelligent without having a big head, you need a neural network that is efficient BUT ALSO compact! Mention 
Szemeredi lemma?

Cooperate or betray? The answer is both mathematical and philosophical in this episode.

The starting point of this episode of our short trips in the land of math: prison. Two prisoners must choose between cooperation and betrayal without consulting each other. This is the famous dilemma that will take us to the heart of game theory and will make us think mathematically about a very philosophical question: is it in our interest to collaborate?
