In condensed-matter physics, channelling (or channeling) is the process that constrains the path of a charged particle in a crystalline solid. [1] [2] [3]Many physical phenomena can occur when a charged particle is incident upon a solid target, e.g., elastic scattering, inelastic energy-loss processes, secondary-electron emission, electromagnetic radiation, nuclear reactions, etc.
Here is a list of people who claim to be mediums or channelers in communication with beings and spirits of the deceased, through the study and practice of mediumship. . Mediumship is the practice of those people known as mediums that allegedly mediate communication between spirits of the dead and living human
The Wheel of Death, in the context of the impalement arts, is a classic moving target stunt sometimes performed by knife throwers.The thrower's assistant or target girl is secured, (usually by the limbs and tied by rope), to a large, generally circular, target board that is free to spin about its center point.
Channeling (New Age), influences attributed to esoteric communications via a person described as a channel; Chopping and channeling of an automobile's body; Legal channeling, a contractual or legal redirection of responsibilities from an organization to another
Modern impalement artists have performed similar feats. In some ways the Tell legend can be seen as one of the earliest inspirations for the impalement arts. Impaling a card or paper plate: The assistant stands in front of the target board and holds out a card, or paper plate which the thrower or archer attempts to pin to the board. The level ...
Emission channeling is an experimental technique for identifying the position of short-lived radioactive atoms in the lattice of a single crystal. [ 1 ] When the radioactive atoms decay, they emit fast charged particles (e.g., α-particles and β-particles ).

Consider quantum channels that transmit only quantum information. This is precisely a quantum operation , whose properties we now summarize. Let H A {\displaystyle H_{A}} and H B {\displaystyle H_{B}} be the state spaces (finite-dimensional Hilbert spaces ) of the sending and receiving ends, respectively, of a channel.
