A brilliant Russian mathematician and physicist, Alexandre Friedmann is one of the founding fathers of modern cosmology.

In 1922, in line with the theory of relativity, Alexandre Friedmann introduced the idea that the universe is not static but dynamic over time, implying in particular an original singularity. This dynamic cosmological model of the general relativity would become the standard for the Big Bang theory and the steady-state model of the universe.

The year 2022 therefore marks the centenary of the publication of Friedmann's articles and the launch of the Alexandre Friedmann fund by the Fondation de l'École polytechnique.
