Quote from the embedded video: > In order to do this we had to build a detector the size of a 10 story building, 2 kilometers underground. In a mine, Creighton Mine, near Sudbury, Ontario... and we had the advantage of a thousand tonnes [of heavy water] on loan from Canada's reserves of heavy water. The value of which was on the order of 300 million dollars. We used that for about 10 years, measuring neutrinos roughly 1 [per] hour. By having this very sensitive detector we were able to make measurements that others could not. But it took [a] team... on the order of 150 people to accomplish this scientific measurement. Pretty astounding work, if you ask me. The dedication of these people should be applauded.
