The Chapter Skim interface presents what we've algorithmically identified as the most significant single chunk of text within every page in the chapter.
Select key terms on the right to highlight them within pages of the chapter.


From page 85...
... Very distant ones are called quasars. Background: False events or unwanted particles traversing the device, preventing useful data taking.
From page 86...
... Dark matter: Matter that does not emit or absorb enough light or other radiation to be observed directly. Dirac-like: A theoretical framework for the introduction of particles with mass into a modern quantum field theory (named for P au]
From page 87...
... Lepton: Any one of a group of six funciamental particles having electroweak interactions assigned in three families (the charged electron, muon, ancT tan, each with its associated neutrino)
From page 88...
... Relic: In this context, particles created in and remaining currently from the big bang or other astrophysical events. Shock, shockwave: A very narrow region of high pressure and temperature formed in a fluid when the fluid flows supersonically over a stationary object or when a projectile flies supersonically through a fluid.
From page 89...
... Standard Model: The theory summarizing the current picture of elementary particle physics. It includes three families of quarks and leptons, the electroweak theory of the weak and electromagnetic forces, and the quantum chromodynamic theory of the strong force.
