Marvel Strike Force allows players to collect Marvel Universe characters from both the heroes and villains and generic characters from large organizations such as S.H.I.E.L.D., The Hand and Hydra, and use them to fight in turn-based battles. Similar to the fighting game Marvel: Contest of Champions, characters fall into one of several classes.
Air shower formation in the atmosphere. First proton collides with a particle in the air creating pions, protons and neutrons. The air shower is formed by interaction of the primary cosmic ray with the atmosphere, and then by subsequent interaction of the secondary particles, and so on. Depending on the type of the primary particle, the shower ...
Coincidence method. In particle physics, the coincidence method (or coincidence technique) is an experimental design through which particle detectors register two or more simultaneous measurements of a particular event through different interaction channels. Detection can be made by sensing the primary particle and/or through the detection of ...
Scintillation counter. Schematic showing incident high energy photon hitting a scintillating crystal, triggering the release of low-energy photons which are then converted into photoelectrons and multiplied in the photomultiplier. A scintillation counter is an instrument for detecting and measuring ionizing radiation by using the excitation ...
Cosmic rays ionize nitrogen and oxygen molecules in the atmosphere, which leads to a number of chemical reactions. Cosmic rays are also responsible for the continuous production of a number of unstable isotopes, such as carbon-14, in the Earth's atmosphere through the reaction: n + 14 N → p + 14 C.
Cosmic time, or cosmological time, is the time coordinate commonly used in the Big Bang models of physical cosmology. [1] [2] [3] Such time coordinate may be defined for a homogeneous , expanding universe so that the universe has the same density everywhere at each moment in time (the fact that this is possible means that the universe is, by ...
As a graduate student at Cornell after World War II, Davisson built a cosmic ray machine that would do everything but write a grad student's thesis. [citation needed] He acquired a huge magnet from Navy surplus, built a cloud chamber and a set of Geiger counters and designed a universal-focus camera to record cosmic ray events. Then he designed ...
Cosmic string. Cosmic strings are hypothetical 1-dimensional topological defects which may have formed during a symmetry-breaking phase transition in the early universe when the topology of the vacuum manifold associated to this symmetry breaking was not simply connected. Their existence was first contemplated by the theoretical physicist Tom ...
