Century Dictionary and Cyclopedia
    • n shears A cutting- or clipping-instrument consisting of two pivoted blades with beveled edges facing each other, such as is used for cutting cloth, or of a single piece of steel bent round until the blades meet, the elasticity of the back causing the blades to spring open when the pressure used in cutting has ceased. The latter is the kind used, by farriers, sheep-shearers, weavers, etc. Shears of the first kind differ from scissors chiefly in being larger. Implements of similar form used for cutting metal are also called shears. See also cuts under clipping-shears and sheep-shears.
    • n shears Something in the form of the blades of shears. (a) A pair of wings.

    “It resembles a pair of shears, so joined that they cannot be separated, often moving in opposite directions, yet always punishing anyone who comes between them.”
  • Tiberius Caesar

    “It is the duty of a good shepherd to shear his sheep, not to skin them.”

    “In levying taxes and in shearing sheep it is well to stop when you get down to the skin.”

When we're thegither shearing.

Unbound their curls; and all in tears,

In science:

If we correct our measurements using a second order polynomial in the difference between measured and true shear, as found by Heymans et al. (2006), we find that most cluster masses stay within +/ − 15% of the mass calculated from uncorrected shear values.
The Cluster Mass Function from Weak Gravitational Lensing
The galaxy shape distortions caused by gravitational lensing provides a measurement of the reduced tangential shear, gT = γT /(1 − κ), where γT is the tangential component of the shear and κ is the convergence.
The Cluster Mass Function from Weak Gravitational Lensing
This is determined by opposite temperature behavior of the bulk and shear viscosities that the bulk viscosity increases while the shear decreases with growing temperature.

Note that this field is also the average field in the shearing sheet box, and is conserved during the evolution thanks to the shearing sheet boundary conditions (Hawley et al. 1995).
Impact of dimensionless numbers on the efficiency of MRI-induced turbulent transport
Statistical averages are computed over 500 shear times, and start after the first 100 shear times to avoid pollution by relaxation of the initial transient dynamics.
Impact of dimensionless numbers on the efficiency of MRI-induced turbulent transport
By generalizing the structures (shear-free null geodesic congruences) associated with the algebraically special metrics to asymptotically shear-free null geodesic congruences, which are available in all asymptotically flat space-times, we give kinematic meaning to the Bondi four-momentum.
On Extracting Physical Content from Asymptotically Flat Space-Time Metrics
Our second and third identification models are based on complex curves, in the second model these curves are associated with flat-space shear-free null geodesic congruences while in the third model they are associated with the asymptotically shear-free null geodesic congruences of the relevant space-time.
On Extracting Physical Content from Asymptotically Flat Space-Time Metrics
Our generalization consisted in observing that the existence of a shear-free nul l geodesic congruence could be generalized to the existence of an asymptotical ly shear-free nul l geodesic congruence.

There are two viscosities, ν1 and ν2 , where ν1 corresponds to the azimuthal shear, the standard shear viscosity in a flat disc, and ν2 is the viscosity associated with vertical shear motions, which smoothes out the warping.

In particular, what may be the effective azimuthal velocity profile of high Re and low Pm disks (or their sections)? As Ebrahimi et al. (2009) recently note, quasi-linear saturation of the shear profile might be an unreasonable expectation given that the strong gravity tends to restore the shear profile within disks (cf.
