neutrino question
Saturday, November 19th, 2011Neutrinos are in the news. Scientists at CERN successfully repeated their recent experiment in which they measure the speed it takes these subatomic particles to go from CERN to the Gran Sasso lab in Italy.
Besides exceeding the speed of light, what’s interesting to me [a non-physicist and non-scientist] about this scenario is the following:
1. Neutrinos pass through solid matter.
2. Neutrinos are neutral [do not possess positive or negative charge].
Therefore I wonder wonder wonder how do scientists and/or technicians steer them? You can’t use mirrors, or magnets, or barrels. How they point those little critters in the desired direction in order to perform their measurements?
The first one who provides the correct answer gets a free beer.
