" 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. 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. On the other hand, the strong or "color" force between quarks gets stronger with distance, so that quarks are always found in colorless combinations called hadrons, a phenomenon known as quark confinement. These are either fermionic baryons composed of three quarks (the proton and neutron being the most familiar example) or bosonic mesons composed of a quark-antiquark pair (such as pions). The mass of such aggregates exceeds that of the components due to their binding energy. Tests and predictions The Standard Model predicted the existence of W and Z bosons, the gluon, the top quark and the charm quark before these particles had been observed. Military Ship Model Their predicted properties were experimentally confirmed with good precision. The Large Electron-Positron collider at CERN tested various predictions about the decay of Z bosons, and found them confirmed. "

" It was at this time that Cindy Crawford successfully leveraged her modelling fame into hosting her own television show, MTV's House of Style, creating and promoting many exercise video tapes, and posing in Playboy (she was the first supermodel/model to do all of these). Supermodels are, almost by definition, sex symbols. Supermodels of today are globally famous, and parlay their celebrity into product endorsement deals and often into acting careers. Supermodels who have made the switch include Milla Jovovich, Elle Macpherson and Rebecca Romijn. According to Forbes magazine, as of 2004, the five highest-paid supermodels in the world were, in descending order, Milla Jovovich, Gisele Bündchen, Heidi Klum, Caroline Murphy, and Tyra Banks [1]. In the past many supermodels were female. However today more and more male models are also becoming famous. Revell Model Ship The position of the world's most famous and highest paid male supermodel is currently contested between Jamaican-American actor and model Tyson Beckford, and Swedish model and bodybuilder Marcus Schenkenberg. In 2005, tired of hearing this label attached to so many people, the musician LeCain, played devil's advocate and commented that a 'measure of success' was necessary to stop TV from tirelessly using the term for every girl wanting model stardom.
