For example, electrons have half-integer spin and are fermions that obey the Pauli exclusion theory, whilst photons have integer spin and don't. The theorem relies on both of those quantum mechanics and the speculation of Specific relativity, and this relationship concerning spin and statistics has long been referred to as http://cubisme.ir/%da%a9%d9%84%d9%85%d8%a7%d8%aa-%da%a9%d9%84%db%8c%d8%af%db%8c-%d8%af%d8%b1-%d8%af%d8%a7%d9%85%d9%86%d9%87-%d9%87%d8%a7%db%8c-%d8%b3%d8%b7%d8%ad-%d8%a8%d8%a7%d9%84%d8%a7-%d8%b9%d9%85%d9%88%d9%85%db%8c/
