How does the atomic nucleus stay together? Since most nuclei contain two or more like-charge particles ( protons), it would appear that they should be unstable, flying apart because of the force of electrical repulsion. In attempting to explain why...

The muon is a subatomic particle that is very similar to the electron but more massive. The mass of the muon is 207 times that of the electron. Muons were first detected in cosmic rays by American physicist Carl D. Anderson in 1936. The muon's mass led...

The muon (from the letter mu (μ)--used to represent it) is an elementary particle with negative electric charge and a spin of 1/2. It has a mean lifetime of 2.2μs, longer than any other unstable lepton, meson or baryon except for the neutron....
