rewarding job

KamLAND by Research Center for Neutrino Science

Last year, I met an American physicist who worked in a huge test center in Toyama, which was constructed using an old mine with a lake inside. There they obseve minute particles called "neutrino", falling onto the earth from space. This field of study bore two Japanese Nobel Prize winners in physics in 2002 and 2015.
When the physicist was practicing to speak about her "rewarding job", she said collecting data by boat in the lake was fulfilling. For me, it was so impressive to know that they enjoy going around the lake on a boat to study such leading-edge physics.
