In spring 2021, the Polytechnic Museum resumed its Sunday Brunches with Scientists organized in the frames of the public programme “Polytech in the city”. These are the meetings over a cup of coffee in the best Moscow cafes and bars at which participants can learn about the latest news of the scientific world.

Yesterday, such a meeting took place in the centre of Moscow, in the Community Moscow restaurant. The guest of the event was Dmitry Naumov, Doctor of Physics and Mathematics, Head of the JINR Neutrino Programme. The host Kirill Fuks, a physicist, a specialist in accompanying visitors of the Polytechnic Museum, interviewed Dmitry Naumov in detail about the construction of the Baikal Neutrino Telescope, neutrino physics, ways to study the evolution of distant galaxies, the path to science, and why it is necessary to invest in basic research. Participants of the brunch had a unique opportunity to get answers from the world-level scientist in the fields of neutrino physics to the most tricky questions.
