| Quarter toneA quarter tone is an interval half as wide (aurally, or logarithmically) as a semitone, which is half a whole tone. In equal temperament the quarter tone is 50 cents or 21/24 or 1. 029302236643. In 24 tone equal temperament, or the quarter tone scale, it | QuinidineQuinidine is a pharmaceutical agent that acts as a class I antiarrhythmic agent in the heart. It is a stereoisomer of quinine, originally derived from the bark of the cinchona tree. Like all other class I antiarrhythmic agents, quinidine primarily works b | Quantum wellA quantum well is a potential well that confines particles in one dimension, forcing them to occupy a planar region. The width of this region is on the order of their de Broglie wavelength, leading to quantized subbands. By doping the barrier of a quantum |
| Quantum tunnelingQuantum tunneling is the quantum-mechanical effect of transitioning through a classically-forbidden energy state. One of the major applications is in electron-tunneling microscopes (see scanning tunneling microscope) used to see objects that are too small | Quiver diagramIn physics, a quiver diagram is a graph representing the matter content of a gauge theory that describes D-branes on orbifolds. Each node of the graph corresponds to a factor U ''N of the gauge group, and each link represents a field in the bi-fundamental | QuinceañeraThe Quinceanera is a young Latina woman's celebration of her fifteenth birthday, which is celebrated in a specific and different way from her other birthdays.
