  1. Any action in resisting other action or force; counter tendency; movement in a contrary direction; reverse action.

  2. (Chem.) The mutual or reciprocal action of chemical agents upon each other, or the action upon such chemical agents of some form of energy, as heat, light, or electricity, resulting in a chemical change in one or more of these agents, with the production of new compounds or the manifestation of distinctive characters. See Blowpipe reaction, Flame reaction, under Blowpipe, and Flame.

  3. (Med.) An action induced by vital resistance to some other action; depression or exhaustion of vital force consequent on overexertion or overstimulation; heightened activity and overaction succeeding depression or shock.

  4. (Mech.) The force which a body subjected to the action of a force from another body exerts upon the latter body in the opposite direction.

reaction

"action in resistance or response to another action or power," 1610s, from re- "again, anew" + action (q.v.).

\nOriginally scientific; physiological sense is attested from 1805; psychological sense first recorded 1887; general sense of "action or feeling in response" (to a statement, event, etc.) is recorded from 1914. Reaction time, "time elapsing between the action of an external stimulus and the giving of a signal in reply," attested by 1874.

Reaction (physics)

As described by the third of Newton's laws of motion of classical mechanics, all forces occur in pairs such that if one object exerts a force on another object, then the second object exerts an equal and opposite reaction force on the first. The third law is also more generally stated as: "To every action there is always opposed an equal reaction: or the mutual actions of two bodies upon each other are always equal, and directed to contrary parts." The attribution of which of the two forces is the action and which is the reaction is arbitrary. Either of the two can be considered the action, while the other is its associated reaction.

(n-p) reaction

The (n-p) reaction is an example of a nuclear reaction. It is the reaction which occurs when a neutron enters a nucleus and a proton leaves the nucleus simultaneously.

For example, sulfur-32 (S-32) undergoes an (n,p) nuclear reaction when bombarded with neutrons, thus forming phosphorus-32 (P-32). The nuclide nitrogen-14 (N-14) can also undergo an (n,p) nuclear reaction to produce carbon-14 (N-14).

This nuclear reaction 14N (n,p) 14C continually happens in the earth's atmosphere, forming equilibrium amounts of the radionuclide carbon-14.

Most (n,p) reactions have threshold neutron energies below which the reaction can not take place as a result of the charged particle in the exit channel requiring energy (usually more than a MeV) to overcome the Coulomb barrier experienced by the emitted proton. The (n,p) nuclear reaction 14N (n,p) 14C is an exception to this rule, and is exothermic - it can take place at all incident neutron energies. This particular 14N (n,p) 14C nuclear reaction is responsible for most of the radiation dose delivered to the human body by thermal neutrons—these thermal neutrons are absorbed by the nitrogen (N-14) in proteins, causing a proton to be emitted; the emitted proton deposits its kinetic energy over a very short distance in the body tissue, thereby depositing radiation dose.

Reaction (album)

Reaction is the second album by American R&B singer Rebbie Jackson. The album was released on March 9, 1986 and spawned two mildly successful singles, " Reaction" and " You Send the Rain Away", a duet with Robin Zander. "Ticket To Love" was going to be released as the second single and received a very limited promo release before being cancelled in favour of " You Send the Rain Away". The album-only track "Tonight I'm Yours", a duet with Isaac Hayes, received substantial airplay but was not commercially released as a single.

Reaction received a limited CD reissue in Japan in the early 1990s. It was reissued on CD with Jackson's previous album Centipede on May 18, 2010. The album was reissued by Funky Town Grooves on CD in October 2012 and included 7 bonus tracks.

Reaction (The Spectacular Spider-Man)

"Reaction" is the eighth episode of the American animated television series The Spectacular Spider-Man, which is based on the comic book character Spider-Man, created by Stan Lee and Steve Ditko. The episode originally broadcast in the United States on the Kids WB! block for The CW on May 3, 2008, where it was rated TV-Y7-FV.

The episode details Dr. Otto Octavius as an accidental laboratory incident caused by the Green Goblin where the radiation merges special mechanical tentacles to his skin and seemingly damaged his brain (although it was later suggested that what was interpreted as brain damage was in fact his mind rewiring itself to accommodate four extra limbs), and turns him from a timid and weak scientist into the villain Dr. Octopus. "Reaction" was directed by Jennifer Coyle and was the first episode of the series to be written by Randy Jandt. While writing the teleplay, Jandt was challenged with staying true to the original material of Spider-Man, particularly towards that of Dr. Octopus.

"Reaction" received generally positive reviews, with television critics singling out Dr. Octopus' portrayal. Octopus's character design was applauded by both the designers and Coyle; the latter noted that his design allowed her to direct them freely in different manners, and that the arms in particular were particularly well-done. Peter MacNicol voiced the character and used a voice inspired by that of late actor Laird Cregar. It is available on both the third volume DVD set for the series, as well as the complete season box set.
