Lecture for “Teaching the Universe” program

Josquin Errard participated to Teaching the Universe (https://ikhone.wixsite.com/univers-teach), a program organized by the Paris Center for Cosmological Physics.
This two-day training aimed at providing an overview of the current research in astroparticles and cosmology to high school teachers.
Josquin gave a presentation about the first minutes of the Universe history, where hydrogen and helium elements were created. This mechanism is one of the pillars of the hot big band scenario, the same scenario B3DCMB project is trying to validate by different means.
