	generic document for building HyperPhysics
		The momentum of an isolated system is a constant.
		The angular momentum of an isolated system remains constant in both magnitude and direction.
		The angular momentum is a vector quantity and the vector sum of the angular momenta of the parts of an isolated system is constant.

	System (thermodynamics) - Wikipedia, the free encyclopedia
		Isolated systems are completely isolated in every way from their environment.
		A system in which all these equalizing processes have gone practically to completion, is considered to be in a state of thermodynamic equilibrium.
		For instance, consider the system of hot liquid water and solid table salt in a sealed, insulated test tube held in a vacuum (the surroundings).

	Isolated system - Wikipedia, the free encyclopedia
		In thermodynamics, an isolated system, as contrasted with a closed system, is a physical system that does not interact with its surroundings.
		It is an acceptable idealization used in constructing mathematical models of certain natural phenomena; e.g., the Sun and planets in our solar system, and the proton and electron in a hydrogen atom are often treated as isolated systems.
		In the attempt to justify the postulate of entropy increase in the second law of thermodynamics, Boltzmann’s H-theorem used equations which assumed a system (e.g., a gas) was isolated: i.e., that all the mechanical degrees of freedom could be specified, treating the walls simply as mirror boundary conditions.

	November-December 2002: Isolated Power Systems
		Where the isolated power system branch circuits supply 125-volt 15- or 20-ampere receptacles, the orange conductor is required to be connected to the terminal on the receptacle that is intended for the grounded conductor (see figure 3).
		Although the isolated power system itself is ungrounded, equipment grounding conductors are required to be installed to the receptacles and connected to the grounding terminal of such receptacles to serve as a ground reference for connected equipment or appliances.
		Where isolated power systems are used to supply power circuits to task illumination, selected receptacles, and fixed equipment in critical care areas that utilize anesthetizing gases, or the system is used in special environments, the isolated power system is required to be supplied by a circuit that supplies no other load (see figure 5).

	Irreversibility and Equilibrium in Biological Systems
		An isolated system would be a system that does not interact with the environment and other systems that surround it.
		This is the meaning of death, and it obeys to the law of thermodynamics that says that all systems in the universe have a tendency to the equilibrium (entropy).
		When a thermodynamic system delays, not stops nor reverts, the increase in its local entropy, it makes that the entropy of the environment, and soon the global entropy, increases by the same magnitude in which it would increase in that thermodynamic system.

	Isolated Systems
		Total system momentum is conserved for collisions occurring in isolated systems.
		A system in which the only forces which contribute to the momentum change of an individual object are the forces acting between the objects themselves can be considered an isolated system.
		The collision occurs in an isolated system as long as friction is small enough that its influence upon the momentum of the billiard balls can be neglected.

		In this case, system isolation brought on by network disconnection may very well be purposeful and expected to continue for the duration of the user's session.
		System isolation is a guarantee that no network access is possible, and will not be possible for much longer than usual network time-out periods, typically ranging from under a second to several seconds.
		System isolation assumes there is no network, mobile or static, so all procedures meant to circumvent the obstacles of a lossy, noisy medium are in vain: there simply is no medium.

	Second law of thermodynamics - Wikipedia, the free encyclopedia
		As a result, the system tends to approach thermal equilibrium, at which point the entropy is at a maximum and the free energy is zero.
		In fact, as hot systems cool down in accordance with the Second Law, it is not unusual for them to undergo spontaneous symmetry breaking, i.e.
		It is conjectured that such systems tend to evolve into complex, structured, critically unstable "edge of chaos" arrangements, which very nearly maximise the rate of energy degradation (the rate of entropy production).

		It is the momentum of the system of balls, not the momentum of an individual ball, that is conserved.
		As the sunbather walks to one end of the raft, she exerts a force on the raft; however, the force is internal to the isolated system.
		Since the linear momentum of the isolated system must remain zero, the raft must acquire a linear momentum that is equal in magnitude and opposite in direction to that of the sunbather.

	Storage and Topology in the Redesigned MAF/TIGER
		The TIGER system, still in use 20 years after its inception, utilizes topological data structures based on the landmark work by Corbett and White (1979, 1981), which relates the mathematics of graph theory and topology to the storage of geographic and cartographic data.
		For the redesigned system, consideration was given to storing the isolated nodes in a separate topology layer, so that they would not interfere with updates to the linear network, especially in regards to snapping and tolerance rules.
		In the legacy TIGER system, while isolated nodes can be linked to a face, they are not actually part of the topology, and so cannot be readily retrieved as if they were components of a face.

	System (closed)
		A traditional cybernetics term connoting a system which is hermetically isolated with respect to environmental influence (e.g., impervious to external "feedback"), and hence not responsive or adaptive to its medium over time.
		This is quite simply not the case, and results from (a) a misinterpretation of Maturana and Varela’s terminology and (b) inattention to the manner in which the explanatory constructs underlying a traditional ascription of system "openness" (e.g., feedback) are addressed in autopoietic theory.
		It could be argued that any satisfactory model of a concrete system must necessarily and simultaneously be open and closed, according to the functional requirements of the system.

	Entropy and the 2nd Law in Open Systems
		But if the temperature is remarkably different, from one part of a system to another, then we can't ignore it, and we have to admit that the system is in a nonequilibrium state.
		If the system were not isolated, then entropy could pour out over the boundary, and the entropy decrease instead of increase.
		You treat each subdomain like an "isolated" system, computing all the internal changes in entropy and energy, and then add in any energy and/or entropy that comes across the boundary from any other subdomain that the subdomain in question is in contact with.

		But due to the isolated circumstances of the group many believe all the bodies will never be recovered, placing the actual loss of life much higher, possibly greater than Jonestown.

	Energy, Entropy, Economics, and Ecology
		Living systems have vast amounts of dynamical freedom of their internal chemical states, but keep within the much smaller subset of phase space where biological integrity is maintained.
		Contemporary scientists know that evolving systems are not isolated, and thus that the Second Law does not fully describe what takes place in them—more precisely, between them and their environment.
		Systems in the third category are always and necessarily open systems, so that change of entropy within them is not determined uniquely by irreversible internal processes.

	Isolated Ground Folly?
		The isolated ground conductor is connected to the ground connector on the receptacle and can then be run back to the service ground bus, unconnected to the ground bus of intermediate panels.
		This explanation is a little weak–first, because such a system is certainly not required by manufacturers of personal computers and, second, because equipment manufacturers are not necessarily the sole authority on power distribution.
		Possibly, some poorly isolated equipment might be sensitive to this–certainly, old-fashioned AC-DC tube-type radios, whose filaments were connected across the AC line, were prone to an annoying 60-Hz hum.

	Momentum and isolated system
		If we think of helicopter and a person together as isolated system then any forces the two exert on each other are considered internal and as such can't change the momentum of the system.
		If a system is isolated from its environment, that means there is no outside interaction or force on it.
		So if a system is isolated, then its momentum is conserved (since the net force on it is zero).

		As a non-isolated system undergoes change, energy can be transferred between the system and its environment; as an isolated system undergoes change, different forms of energy can interconvert to change the distribution of energy even though the total energy stays constant.
		Work can be thought of as a process of transferring energy from the environment to the system (or from the system to its environment) by the action of a force.
		There is an external force on the system (your friend on her bike) and this force has a nonzero displacement because it is applied to the handlebars which move along with the bike.
