Example Sentences

At times, the narratives feel disjointed and bogged down in arcane details and enigmatic concepts, for example, in a passage where Bobby discusses the theories of the physicist Steven Weinberg: “Still he figured that if you had these neutrino-nucleon collisions that spun off the W particle and gave you a lepton with the opposite charge you’d have to get a Z particle every once in a while. And since the Z carried no charge this meant that the neutrino coming in would stay a neutrino.”

From New York Times

That would also include studies of the W particle and bottom quark, which would also be produced in profusion.

From Scientific American

The W particle will then decay in a characteristic way, leaving an unambiguous record of the neutrino’s passage.

From Economist

The detection of the W particle is an example of extraordinary scientific sleuthing, comparable to finding a missing person in a crowd of a billion people.

Using one of the world's most powerful atom smashers, Italy's Carlo Rubbia, 48, and his team of 134 European and American scientists appear to have snared a trophy that has been the dream of physicists for two generations: discovery of the so-called W particle, the elusive carrier of one of the universe's basic forces.
