|Positive feedback |
From Wikipedia, the free encyclopedia
Positive feedback, sometimes referred to as "cumulative causation", refers to situations where some force is amplified, then summed to its input. Positive feedback often leads to oscillation. Thus, mechanical, electrical, chemical, economic, or other systems should be damped via frictional forces or added negative feedback for system stability.
Under strong positive feedback, in absence of stabilizing forces, systems accelerate towards a non-linear (chaotic, unpredictable) region, which is often accompanied with a large release of energy and deformation. Thermal runaway destroys semiconductor junctions. Positive feedback in chemical reactions causes explosions. Positive feedback in the mechanical world cause bridges to collapse. Positive feedback in economic systems cause well-known boom, then bust cycles.
After this release of energy, then the system may move into a new stable state if the positive feedback is somehow negated or damped.
The effect of a positive feedback loop may not be "positive" in the sense of being desirable. Positive refers to the direction of change rather than the desirability of the outcome. A negative feedback loop tends to reduce or inhibit or stabilize a process, while a positive feedback loop tends to expand or promote it and will often ultimately destabilize it.

Danger! Danger!! Our Democracy is in great DANGER!!!
Ithaca, NY (WBNG Binghamton) The Speaker of the United States House of Representatives taps into the natural gas drilling debate here in the Southern Tier.
* Watch The Video
Nancy Pelosi was at Cornell University for its convocation Saturday.
Talking to the media Saturday morning, she says she's excited about the opportunity that lies in the lucrative Marcellus Shale.
Pelosi says she is working to reduce our dependence on foreign oil and says she thinks natural gas is better option.
But adds the decision to drill should weigh the benefit to the community versus the environmental impact.
"It's cheaper. It's American and it's abundant and it's here. But we have to recognize that it's not a final answer it's a transition to renewables until they are all in place. Is it that worth judging community to community? That community input is very important," said Pelosi.
Pelosi also says she is confident Democrats will still be dominant in the House after the midterm elections.
