The π exhibition of the Palais de la découverte, famous throughout the world, receives many visitors and school groups of all levels each year.

The 704 decimal places on display since 1950 (just like the 10,000 billion calculated today) are of no particular practical, or even mathematical, interest. However, the methods of calculating them and the search for powerful algorithms to produce these records are fascinating.



2. Mathematics balcony

The maths balcony is not accessible to people with restricted mobility.

There are pictures throughout this section on the theme of "Patrice Jeener explores mathematics". The exhibition presents:

8 displays about "polyhedrons"
  • the famous Platonic solids, i.e. regular convex polyhedrons: all sides are regular identical polygons, and the same number of sides meet at each point
  • new types of polyhedrons, which have only been introduced recently to mathematics, addressing certain aspects of topology and fractal geometry
Probability and statistics

The law of large numbers, normal distribution, sampling margin of error, etc. An interactive display teaches you about the mathematics of risk.


3. Symmetry

What link is there between a Muslim Arab fresco, a piece of glass, a starfish, a molecule of water and a prelude by Johann Sebastian Bach? They all contain symmetry. What is symmetry? How can you recognise symmetry in an object? Why should we study it?

Multimedia, discovery through touch, objects to be handled, musical book and more. This interactive exhibition explores the idea of symmetry, making connections between the worlds of mathematics, the arts and other scientific disciplines.
