“His features went from annoyance to shock, surprise, perturbation, and then something like a tightly constricted anger.”

“It is believed that a minor perturbation in solar heating caused by orbital changes could lead to another ice age or warming period.”

“In cold advection the cyclonically rotating ascent to the right is opposed by decent forced by the linear pressure perturbation.”

“There's less of it with you to provide for, and it's less a perturber of your reckoning.”

“This action takes place if a slate, a pane of glass, or a shingle is interposed between the needle and its perturber.”

“Couple therapy carefully avoids blaming one of both partners for the perturbance.”

“With thousands of generators and hundreds of thousands of miles of lines, the network became so interconnected that even on a normal day a single perturbance can be detected thousands of miles away.”

“The accelerometer perturbance was simulated with normal distribution.”

“Electrical action potentials, osmotic perturbations or chemical signals may trigger these waves.”

“The hard perturbations in this study caused the trajectory to move in a direction that was normal to the limit cycle.”

“The complex shear modulus, measured in response to nanoscale oscillatory perturbations, exhibited soft-glassy rheology.”
