Perturbation in a sentence as a noun

It's roughly as small of a perturbation to the radiation field as, say, a tinfoil hat.

Could you please elaborate on this perturbation problem?

The idea of smoothed complexity is simply to add random perturbation to the input and then measure the worst case.

See, the wider system may be more complex, and have negative feedbacks that overwhelm any perturbation you introduce.

Eventually as the perturbation distance became smaller, the convergence process would "stall".

I had a teacher make seating charts in Bingo Card Creator by exploiting the fact that, for the free trial, the random perturbation of the words is deterministic.

From the article: What’s more surprising is that the same perturbation can cause a different network, which was trained on a different training dataset, to misclassify the same image.

Not only that, but that larger perturbations worked better at the beginning of the convergence, and smaller perturbations worked better toward the end of the convergence.

My understanding is that no one knows yet whether the non-renormalizability of gravity in QFT near the Planck scale is necessarily a sign that the theory breaks, rather than just a problem with perturbation theory.

My end product is also a computer simulation, as far as that goes, but I'm taking an obsessively data-driven approach, motivated by the advent of new technologies for single-neuron measurement and perturbation in living, behaving animals.

It's perfect, even - if you really need all the gory stuff, sure, go get a copy of Jackson's book, or some 800 page tome on perturbation theory and the rigorous mathematical underpinnings of quantum theory, if you're going into the field you should absolutely know more than you can get from an intro text.

The "negative" possibility is a reemergence of old-style landed gentry, where wealth passes down from generation to generation with relatively little perturbation or erosion, interrupted only in the case of the "bad apple" bone-headed heir who actively blows the family fortune.

This is so totally bonkers it is hard to know where to start, but perhaps an easy place is: how would you go about isolating a single quark and a single gluon in the horrible nonperturbative mess that is the QCD vacuum[0].If you want to program the nucleons in the nucleus, you can switch your description to chiral perturbation theory[1], which is weakly coupled, but you need to be able to shoot individual pions at individual nuclei, which would be extremely difficult, and might require enough energy to liberate the target nucleon from the rest of the nucleus, anyway, destroying your "computer".
