Counterculture of the 1960s of Timothy Leary to "Turn on, tune in, drop out", hoped to change society by dropping out of it. Looking back on his own life (as a Harvard professor) prior to 1960, Leary interpreted it to have been that of "an anonymous institutional employee who drove to work each morning in a long line of commuter cars and drove home each night and drank martinis ... like several million middle-class, liberal, intellectual robots." As members of the hippie movement grew older and moderated their lives and their views, and especially after US involvement in the Vietnam War ended in the
Tune shift with amplitude Tune shift with amplitude The tune shift with amplitude is an important concept in circular accelerators or synchrotrons. The machine may be described via a symplectic one turn map at each position, which may be thought of as the Poincaire section of the dynamics. A simple harmonic oscillator has a constant tune for all initial positions in phase space. Adding some non-linearity results in a variation of the tune with amplitude. Amplitude may refer to either the initial position, or more formally, the initial action of the particle. Consider dynamics in phase space. These dynamics are assumed to be determined
