Scientists would like to learn more about science, so they set up labs in three places: a mountain near Japan, underground on the border of Switzerland, France, and on the side of a mountain near the Arctic Circle according to Scholastic.
These scientists are learning about particles and other science things by, for example, under the mountain near Japan, they built somewhere called a Super-K.
"The Super-K is six-story-high located more than a mile below Mount Ikenoyama. Inside, walls lined with light-sensing detectors surround a pole of water. When a neutrino hits the water, a tiny cone of light. The detectors see the light and send information about the neutrino to computers."
