Identical particles fermions, which do not share quantum states as described by the Pauli exclusion principle. Examples of bosons are photons, gluons, phonons, helium-4 nuclei and all mesons. Examples of fermions are electrons, neutrinos, quarks, protons, neutrons, and helium-3 nuclei. The fact that particles can be identical has important consequences in statistical mechanics. Calculations in statistical mechanics rely on probabilistic arguments, which are sensitive to whether or not the objects being studied are identical. As a result, identical particles exhibit markedly different statistical behaviour from distinguishable particles. For example, the indistinguishability of particles has been proposed as a solution to Gibbs' mixing
3 Quarks Daily had reached thirty-five thousand. Since then, "3 Quarks Daily" has culled content from hundreds of sources, from blogs such as Salon, Science Daily, and The Huffington Post, from major publications such as "The New York Times", "Nature", and "The Guardian", to smaller outlets such as "Guernica Magazine", "The Awl", and "The American Scholar". The name "3 Quarks Daily" comes from the elementary nuclear particles of physics which in turn were named after the word "quark" which James Joyce had used in Finnegans Wake. The confluence of references to both science and literature in a single word suited the intent of
