" 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. The Lagrangian of each set of mediating bosons is invariant under a transformation called a gauge transformation, so these mediating bosons are referred to as gauge bosons . The bosons in the Standard Model are: Unsolved problems in physics: Parameters in the Standard Model: What gives rise to the Standard Model of particle physics? Why do its particle masses and coupling constants possess the values we have measured? Does the Higgs boson predicted by the model really exist? Why are there three generations of particles in the Standard Model? Is the Standard Model reality, a good approximation to reality, or fatally flawed? Photons, which mediate the electromagnetic interaction. W and Z bosons, which mediate the weak nuclear force Eight species of gluons, which mediate the strong nuclear force. Six of these gluons are labelled as pairs of "colors" and "anti-colors" (for example, a gluon can carry "red" and "anti-green". ) The other two species are a more complex mix of colors and anti-colors. The Higgs bosons, which induce spontaneous symmetry breaking of the gauge groups and are responsible for the existence of inertial mass. Free 3d Max Model Airplane It turns out that the gauge transformations of the gauge bosons can be exactly described using a unitary group called a "gauge group". The gauge group of the strong interaction is SU(3), and the gauge group of the electroweak interaction is SU(2)×U(1). "

" The complexity of this supposed relationship also gives rise to a "moral division of labor", in which "officials have and give the facts," and "reporters merely get them". Journalists are then supposed to adopt an uncritical attitude that makes it possible for them to accept corporate values without experiencing cognitive dissonance. During the year 2005 in the USA, the Government Accountability Office (GAO) criticised the George W. Bush administration for the preparation and distribution of videos which falsely give the impression of being interviews made independently of the administration. The New York Times claimed that more than 20 federal agencies, including the State Department and the Defense Department, now create fake news clips. The Bush administration spent $254 million in its first four years on contracts with public relations firms, more than double the amount spent by the Clinton administration. [1] [2] Flak The term "flak" has been used to describe what Chomsky and Herman see as targeted efforts to discredit organizations or individuals who disagree with or cast doubt on the prevailing assumptions which Chomsky and Herman view as favorable to established power (e. 3d C17 Modelg. , "The Establishment").
