For example, electrons have 50 percent-integer spin and so are fermions that obey the Pauli exclusion principle, although photons have integer spin and do not. The theorem depends on both quantum mechanics and the speculation of Unique relativity, which relationship amongst spin and stats is called "among The most crucial https://archkala.ir/%d9%84%db%8c%d9%84%db%8c-%d8%b1%db%8c-%d8%a7%d8%b2-path-interactive-%d8%b1%d9%be%d9%88%d8%b1%d8%aa%d8%a7%da%98-%d8%a2%da%af%d9%87%db%8c/
