Wikipedia

  1. unstable

    In dynamical systems instability means that some of the outputs or internal states increase with time, without bounds. Not all systems that are not stable are unstable; systems can also be marginally stable or exhibit limit cycle behavior. In structural engineering, a structural beam or column can become unstable when excessive compressive load is applied. Beyond a certain threshold, structural deflections magnify stresses, which in turn increases deflections. This can take the form of buckling or crippling. The general field of study is called structural stability. Atmospheric instability is a major component of all weather systems on Earth.

  1. Unstable

    Unstable is Adema's second and also final album to feature its original lineup with Chavez and Ransom departing from the band after its release and then again after their reunion. It was released on August 12, 2003. It has sold about 400,000 copies worldwide. Its radio single was the self-titled song "Unstable", which also had a music video, but it didn't get very much radio play. Many songs relied more on instrumentation and harmony instead of distortion in comparison to their previous album, but the album also has some of the band's most aggressive work. It was less successful than their first album, debuting at number 43 on the Billboard 200 before quickly falling off the chart.
