The 108th birthday of Bruno Pontecorvo

Today, on 22 August, it is the 108th birthday of Bruno Maximovich Pontecorvo, a renowned Italian and Soviet scientist whose ideas and visions anticipated discoveries later recognized by Nobel Prizes. For instance, Pontecorvo’s idea, proposed as far back as 1957, that neutrinos change their type with time according to a periodical law was confirmed. At present, this phenomenon is known as neutrino oscillations. And the Nobel Prize for experimental discovery of neutrino oscillations was awarded only in 2015.
 

In his interview to the TASS Russian News Agency, professor Takaaki Kajita called Bruno Pontecorvo his predecessor. “His ideas became a basis for my research, we just confirmed the correctness of this theory through practice... Bruno Pontecorvo was the first who presented the grounds for existence of neutrino oscillations and for the fact that neutrinos have masses. This Soviet scientist was a pathfinder and leader.”

Neutrino physics, a scientific direction established by Bruno Pontecorvo, is one of top priority directions of the Dzhelepov Laboratory of Nuclear Problems now. The Baikal Neutrino Telescope is being constructed within it, DLNP scientists are taking an active part in neutrino experiments (DANSS, GERDA, NOvA, Borexino, GEMMA and JUNO) and in other projects significant for world science.

The interior of the study of the scientist, his manuscripts, photographs and personal things are being carefully preserved in the main DLNP building.
