91Propagator — This article is about Quantum field theory. For plant propagation, see Plant propagation. Quantum field theory …
92Rigid rotor — The rigid rotor is a mechanical model that is used to explain rotating systems. An arbitrary rigid rotor is a 3 dimensional rigid object, such as a top. To orient such an object in space three angles are required. A special rigid rotor is the… …

94Particle tracking velocimetry — (PTV) is one of velocimetry methods, i.e a technique to measure velocity of particles. The name suggests that the particles are tracked, and not only recorded as an image as it is suggested in another form, particle image velocimetry. There are… …
95Clifford torus — In geometric topology, the Clifford torus is a special kind of torus sitting inside R4. Alternatively, it can be seen as a torus sitting inside C2 since C2 is topologically the same space as R4. Furthermore, every point of the Clifford torus lies …

97Quantum field theory — In quantum field theory (QFT) the forces between particles are mediated by other particles. For instance, the electromagnetic force between two electrons is caused by an exchange of photons. But quantum field theory applies to all fundamental… …

99Routhian — In the branch of physics known as dynamics the Routhian is a hybrid of the Lagrangian and the Hamiltonian for a system. The Hamiltonian can be obtained by a Legendre transform of the Lagrangian; if this transformation is performed only with… …
