" In order to compute this quantity, physicists have to set up a lattice model and try out various masses for the quarks until the model comes up with a close fit with experimental data. Since the masses of the first generation quarks are significantly below the QCD scale, the uncertainties here are pretty large . In fact, current QCD lattice models seem to suggest a significantly lower mass of these quarks from that of this table. The fermions can be arranged in three generations, the first one consisting of the electron, the up and down quarks, and the electron neutrino. All ordinary matter is made from first generation particles; the higher generation particles decay quickly into the first generation ones and can only be generated for a short time in high-energy experiments. The reason for arranging them in generations is that the four fermions in each generation behave almost exactly like their counterparts in the other generations; the only difference is in their masses. For example, the electron and the muon both have half-integer spin and unit electric charge, but the muon is about 200 times more massive. Model Car Racing The electron and the electron-neutrino, and their counterparts in the other generations, are called "leptons", "weakly interacting particles". Unlike the quarks, they do not possess a quality called "color", and their interactions are only weak and electromagnetic, and fall off with distance. "

"" (Understanding Power, 18f; emphasis in the original) And so the book studies the examples regarded as paradigmatic examples of the independence of the press, such as the Vietnam war, Watergate, and the Iran-Contra Affair, and argues that these examples actually confirm the model. They also looked at what they perceived as naturally-occurring "historical control groups" where two events, similar in their relevant properties but differing in the expected media attitude towards them, are contrasted using objective measures such as coverage of key events (measured in column inches) or editorials favoring a particular issue (measured in number). Finally, the authors examine what points of view they believe are expressed in the media. In one case, the authors examined over fifty of Stephen Kinzer's articles about Nicaragua in the New York Times. They criticize Kinzer for failing to quote a single person in Nicaragua who is pro-Sandinista and contrast this with polls that Chomsky and Herman cite as reporting a 9% support for all the opposition parties taken together. Based on this example and select others, the authors conclude that such a persistent bias can only be explained by a model like the one they advocate. Applications Since the publication of Manufacturing Consent, both Herman and Chomsky have adopted the theory and have given it a prominent role in their writings, lectures, and theoretical frameworks. Model Car For Sale Chomsky, in particular, has made extensive use of its explanative power to lend support to his own interpretations of mainstream media attitudes towards a wide array of events, including the following: Gulf War (1990) Panama invasion (1989) Iraq invasion (2003). Herman, seeking to build upon a more institutionalized framework to analyze mainstream media functioning, joined the media watchdog group Fairness and Accuracy in Reporting (FAIR), which has as its goal the critique, documentation, and statistical analysis of what it alleges is media bias and censorship since 1986.
