Tune shift with amplitude of the system. When the tune reaches resonant values, it can be unstable, and thus a tune-shift with amplitude can limit the stability region, or dynamic aperture. In classical mechanics, a simple example of a system with tune shift with amplitude is a pendulum. In accelerator physics, both the transverse and the longitudinal dynamics show tune shift with amplitude. A simple model of the transverse dynamics is of an oscillator with a single sextupole, it is referred to as the Hénon map. Another model for this case is the Standard Map. An important example is the typical case of distributed
What a Way to Go: Life at the End of Empire with Peak Oil, Climate Change, Mass Extinction, Population Overshoot and the demise of the American lifestyle." What a Way to Go: Life at the End of Empire What A Way To Go: Life at the End of Empire is a 2007 documentary film about the current situation facing humanity and the world. It discusses issues such as peak oil, climate change and the effects of global warming, population overshoot and species extinction, as well as how this situation has developed. The documentary features supporting data and interviews of Daniel Quinn, environmental activist Derrick Jensen and academics such as Richard Heinberg
