Usage

In literature:

I place the tank in front of the lens, in contact with the lens-mount.

Prints are often copied by mere contact, without the use of any lens whatever.
"Notes and Queries, Number 210, November 5, 1853" by Various
They're safe man, go on, it's easy, just like putting in a big contact lens.

In science:

In this paper we develop an invariant for Legendrian knots in the lens spaces L(p, q) for q 6= 1 with the unique universally tight contact structure.
Invariants for Legendrian knots in lens spaces
As noted above, Sabloff ’s invariant is defined for contact manifolds which are smooth S 1 bundles, a class which excludes the lens spaces L(p, q) for q 6= 1.
Invariants for Legendrian knots in lens spaces
Specifically, we develop a model of job markets where social contacts play a pivotal role; and then proceed to analyze it through the stable matching lens.
Social Networks and Stable Matchings in the Job Market
It was claimed, however, that there is an anomalous distance dependence of the gradient of the electric force, used for calibration of the Casimir setup, between an Au plate and an Au spherical lens of 30 mm radius.46 The respective contact potential was found to be separationdependent.
The Casimir Effect and the Foundations of Statistical Physics
Transmission gratings are used mostly in conjunction with a prism (‘grism’) or a lens (‘grens’), either in contact or air-spaced.
Classical Spectroscopy
Lagrangian (Section 7); • the Euler characteristic and first Chern class of the manifold (Section 8); and • embedded lens spaces, including when they admit induced contact structures and when said contact structures are tight or overtwisted (Section 9.2).
Four dimensions from two in symplectic topology
If there is a point x0 ∈ R2 such that Ψ(γ ) is transverse to al l lines through x0 and those lines through x0 that intersect the endpoints of Ψ(γ ) are tangent to the image of ∂RB at those intersections, then the lens space has an induced contact structure.
Four dimensions from two in symplectic topology
For visible lens spaces, there is an easy way detect overtwistedness of a contact structure.
Four dimensions from two in symplectic topology
If the image of Int(γ ) intersects any line through x0 more than once, then the induced contact structure on the lens space is overtwisted.
