" To date, almost all experimental tests of the three forces described by the Standard Model have agreed with its predictions. However, the Standard Model is not a complete theory of fundamental interactions, primarily because it does not describe gravity . The Standard Model The Standard Model contains both fermionic and bosonic fundamental particles. Fermions are particles which possess half-integer spin and obey the Pauli exclusion principle, which states that no fermions can share the same quantum state. Bosons possess integer spin and do not obey the Pauli exclusion principle. Informally speaking, fermions are particles of matter and bosons are particles that transmit forces. For a detailed description of the differences between fermions and bosons, see the article on identical particles. World War 2 Plastic Ship Model In the Standard Model, the theory of the electroweak interaction (which describes the weak and electromagnetic interactions) is combined with the theory of quantum chromodynamics. All of these theories are gauge theories, meaning that they model the forces between fermions by coupling them to bosons which mediate (or "carry") the forces. "

" (4) constituting, i. e. , the original is constituted by the model and that makes devations from model to original imposible. On ontology is in constituting reference mode to the domain it constitutes. The distinction between descriptive and prescriptive reference mode goes at least back to Wieringa, [2]. More detail and references regarding models and modeling can be found, e. g. Wholesale Model Ship, in [3]. II. "
