Chemical reaction

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no change to the elements present), and can often be described by a chemical equation. Nuclear chemistry is a sub-discipline of chemistry that involves the chemical reactions of unstable and radioactive elements where both electronic and nuclear changes may occur.

The substance (or substances) initially involved in a chemical reaction are called reactants or reagents. Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants. Reactions often consist of a sequence of individual sub-steps, the so-called elementary reactions, and the information on the precise course of action is part of the reaction mechanism. Chemical reactions are described with chemical equations, which symbolically present the starting materials, end products, and sometimes intermediate products and reaction conditions.

Reaction (song)

"Reaction" is a song by American R&B singer Rebbie Jackson and the title track from her album of the same name, released as a single in 1986. The single peaked at number fifteen on the Billboard dance chart and number sixteen on the Billboard R&B chart. The single was released on a 12" format, including an extended dance mix, radio edit, and dub. The single was also released in a 7" format, including a radio edit and instrumental version.

Massive! (TV programme)

Massive! was a short-lived Saturday morning British television programme aimed at a "youth" audience. It ran for two seasons, each of 22 episodes, between 1995 and 1996. A spin-off from the children's Saturday morning show Scratchy and Co, Massive! was aimed at a slightly older audience, and was presented by Denise van Outen.

One of the regular guests on the show was the horror-themed magician Simon Drake, who made a number of appearances on the show performing both sleight-of-hand tricks and larger illusions. One of these larger illusions, a sawing in half performed using van Outen as the assistant being sawed in half, drew a large number of viewer complaints due to the liberal use of fake blood, and the fact that van Outen was not restored into one piece before the show cut to a commercial break. Following an investigation of these complaints, the British television regulator, the ITC, warned the show's producers to moderate its content.

After the show's second season, it was cancelled due to low viewing figures, and some of its content incorporated into a revised version of Scratchy and Co.

MASSIVE (software)

MASSIVE (Multiple Agent Simulation System in Virtual Environment) is a high-end computer animation and artificial intelligence software package used for generating crowd-related visual effects for film and television.

Overview

Massive is a software package developed by Stephen Regelous for the visual effects industry. Its flagship feature is the ability to quickly and easily create thousands (or up to millions with current advances in computer processing power) of agents that all act as individuals as opposed to content creators individually animating or programming the agents by hand. Through the use of fuzzy logic, the software enables every agent to respond individually to its surroundings, including other agents. These reactions affect the agent's behaviour, changing how they act by controlling pre-recorded animation clips, for example by blending between such clips, to create characters that move, act, and react realistically. These pre-recorded animation clips can come from motion-capture sessions, or can be hand-animated in other 3D animation software packages.
