A great disturbance or disruption caused by humans.
Harmonic perturbation refers to a periodic external force or disturbance applied to a system that is close to its natural harmonic frequency. This perturbation can affect the behavior of the system, causing resonance or other dynamic responses that are not present in the absence of the perturbation. Understanding and analyzing harmonic perturbation is important in various fields such as physics, engineering, and biology.
Anthropogenic effects, processes or materials are those that are derived from human activities, as opposed to those occurring in natural environments without human influence.
Sulfur hexafluoride (SF6) is a gas that is entirely anthropogenic, meaning it is created by human activities. It is a potent greenhouse gas with a high global warming potential.
Anthropogenic fluxes refer to the flow or movement of materials, substances, or energy that are caused by human activities. These can include emissions of pollutants, transport of goods, or changes in land use that have measurable impacts on the environment.
Anthropogenic action means activities that are produced or caused by humans, usually used in a negative way. For example, polluted and degraded soil can be contributed to pesticides and fertilizer (man-made materials).
We discovered that the perturbation was coming from a fight in the neighbor's yard.
'Anthropogenic' means 'manmade'.

Anthropogenic factors are human activities that change the environment.

The doctor says, "A great perturbation in nature, to receive at once the benefit of sleep, and do the effects of watching!". "Perturbation" means a disturbance, and to the mind of the doctor, the disturbance in nature is the fact of sleepwalking, where one can be asleep but act as if one is awake. The perturbation in nature does not cause the sleepwalking, it IS the sleepwalking.
Perturbation is a noun for anxiety or mental uneasiness; a cause of anxiety or mental uneasiness; or a deviation of system or moving object from its normal function or direction. Example sentence:His perturbation was a telltale sign that anyone could recognise and respond to.
Perturbation function is a mathematical term. It refers to a function that relates to both primal and dual problems. It is sometimes called the bifunction. The value function is also sometimes called the perturbation function.
Common perturbation theory problems encountered in quantum mechanics include the calculation of energy shifts and wavefunction corrections for a system when a small perturbation is applied. Solutions to these problems involve using perturbation theory formulas to calculate the first-order and higher-order corrections to the energy levels and wavefunctions of the system. These corrections help to account for the effects of the perturbation on the system's behavior and provide a more accurate description of its quantum properties.
