Oscillation is the repetitive or periodic variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples of oscillation include a swinging pendulum and alternating current. Oscillations can be used in physics to approximate complex interactions, such ...
Oscillation of a sequence (shown in blue) is the difference between the limit superior and limit inferior of the sequence. In mathematics, the oscillation of a function or a sequence is a number that quantifies how much that sequence or function varies between its extreme values as it approaches infinity or a point.
Digital note-taking offers flexibility and convenience that traditional handwritten notes can’t match. With seemingly unlimited space, you’ll never run out of room to capture ideas, lists, or ...
The Q factor is a parameter that describes the resonance behavior of an underdamped harmonic oscillator (resonator). Sinusoidally driven resonators having higher Q factors resonate with greater amplitudes (at the resonant frequency) but have a smaller range of frequencies around that frequency for which they resonate; the range of frequencies for which the oscillator resonates is called the ...

The earliest written record of the Peierls transition was presented at the 1954 École de physique des Houches.These lecture notes (shown below) contain Rudolf Peierls' handwritten equations and figures, and can be viewed [3] in the library of the Institut Laue–Langevin, in Grenoble, France.
, ordinary frequency, the number of oscillations that occur each second of time. φ {\displaystyle \varphi } , phase , specifies (in radians ) where in its cycle the oscillation is at t = 0. When φ {\displaystyle \varphi } is non-zero, the entire waveform appears to be shifted backwards in time by the amount φ ω {\displaystyle {\tfrac ...
The period T is the time taken to complete one cycle of an oscillation or rotation. The frequency and the period are related by the equation [ 4 ] f = 1 T . {\displaystyle f={\frac {1}{T}}.} The term temporal frequency is used to emphasise that the frequency is characterised by the number of occurrences of a repeating event per unit time.
