perturbations in a sentence 9 out of 10 based on 10 ratings.

use perturbations in a sentence.

Those are stationary perturbations they are talking about, the ones they use to map the region.

If the situation was chaotic (which I would presume a system with many random perturbations to be) the expectation is for the repeated small changes to have a significant impact.

Robustness - "the persistence of a system’s characteristic behavior under perturbations or unusual or conditions of uncertainty".

The difference between an chaotic and an non chaotic system is, how small perturbations propagate.

The key to really getting this for me was:You may also want to remember that it is the barycenter of the Earth-Moon system that moves in an ellipse around the Sun, and that the orbits of both the Earth and the Moon are perturbations of this ellipse.

Well, they did mention one fundamental problem which also hints at the solution: the system is too optimized thus it is very fragile, susceptible to amplify even tiny perturbations.

Dark matter involves hypothesizing something that is being hypothesized solely to explain certain cosmological problemsMuch as in the 1840s, Urbain Le Verrier predicted the position of the then-undiscovered planet Neptune after analysing perturbations in the orbit of Uranus?
