Define ℓ as the mean longitude, the angular distance of the body from the same reference direction, assuming it moves with uniform angular motion as with the mean anomaly. Thus mean anomaly is also [6] = . Mean angular motion can also be expressed, = , where μ is the gravitational parameter, which varies with the masses of the objects, and a ...
In physics, quantum mechanics, and quantum field theory, an anomaly is a breaking of a symmetry which exists at the classical level. Anomalous global symmetries are often consistent, but anomalous gauge symmetries are usually inconsistent.
Flyby anomaly, an unexpected energy increase during the flybys of the Earth by various satellites; Mean anomaly, a measure of time in the study of orbital dynamics; Pioneer anomaly, the observed deviation of the trajectories of some uncrewed space probes, and especially Pioneer 10 and Pioneer 11
An orbiting body's mean longitude is calculated L = Ω + ω + M, where Ω is the longitude of the ascending node, ω is the argument of the pericenter and M is the mean anomaly, the body's angular distance from the pericenter as if it moved with constant speed rather than with the variable speed of an elliptical orbit.
Such functions can be expressed as periodic series of any continuously increasing angular variable, [6] and the variable of most interest is the mean anomaly, M. Because it increases uniformly with time, expressing any other variable as a series in mean anomaly is essentially the same as expressing it in terms of time.
The Mean Anomaly is the angle, at any time, t, in a circular orbit with period T. Thus M, the Mean Anomaly, M, in radians, at time t, is just M =(2*pi/T)*t = nt. We only need to know the period of the orbit to calculate M. It is the first step for calculation of the Eccentric Anomaly. For example, once we know T, we know n, the mean motion, n ...
The Pentagon has failed its annual financial audit for the seventh year in a row. This means the Department of Defense (DOD) has failed every single audit it has been subjected to, but officials ...
A global anomaly is the quantum violation of a global symmetry current conservation. A global anomaly can also mean that a non-perturbative global anomaly cannot be captured by one loop or any loop perturbative Feynman diagram calculations—examples include the Witten anomaly and Wang–Wen–Witten anomaly.
