Blood-red at dusk of sullen noon;

Have vanish'd from his failing sight;
One broad horizon spreads in gloom
Around a lessening disc of light.

And sits in Sirius' disc all night,
Till day makes him retrace his flight
With smell of burning on every plume,
Back past the sun to an earthly room.
"Bond And Free" by Robert Frost
The morning waned-the sun rose high
O'erhead, until 'twas seeming
But a dazzling disc, and the fiery sky
Like an opal sea was gleaming;
And languorous flowers - of morn gone by,
And coming eve - fell dreaming.
"When The Light Is As Darkness" by Harry Breaker Morant
The sun a splintered splendor was
In trees, whose waving branches blurred
Its disc, that day we went together,
'Mid wild-bee hum and whirring buzz
Of insects, through the fields that purred
With Summer in the perfect weather.

A valley filled with dark, quiet, leaf-thick trees,
Loaded with green, cold, faintly shining suns;

And to see nothing move and hear no sound!

After more than 50 years on the radio, the disc jockey is still going strong, playing sentimental songs and taking dedications.
Unlike typical tortillas, these hand-formed discs are nearly a quarter-inch thick and are made to order.
A former general manager of KVMR, Joseph Guida launched his broadcast career as a disc jockey at his college radio station.
) returns with their third album, Plastic Beach, after selling nearly 15 million discs so far and earning five Grammy noms in 2006 (the same year they opened the show performing with an animated Madonna.).
He wanted to be a disc jockey.

First up, fans can stream the title track from the disc, the third song previewed from the upcoming effort.
The disc will be preceded by the first single 'Figure It Out,' which is set to surface shortly.
This may just be the best partitioning utility/boot disc on the planet.

In science:

However, we are viewing the disc in IP Peg at an unusual angle (nearly edge on), and whilst it may be that the discs are optically thin when viewed from the pole, the large column length to the secondary star at phase 0.5 may be enough to obscure it.
A TiO study of the dwarf nova IP Pegasi
This means obscuration of the secondary star by the disc is unlikely, given the star’s position well clear of the disc at this phase.
A TiO study of the dwarf nova IP Pegasi
The three dimensional distribution of velocities within a galactic disc contains a wealth of information about disc structure.
Disc heating in NGC 2985
It has long been known that the random velocity of disc stars increases over their lifetime, a process dubbed disc heating.
Disc heating in NGC 2985
Within this approximation, then, to leading order the shape of the velocity ellipsoid in the plane of the disc is a property of the galactic potential, independent of any disc heating mechanism.
Disc heating in NGC 2985
The idea is to double the space, except for the points on the boundary. (This mimics the method of mirror charges in classical electrodynamics.) For Σ a disc, the double ˆΣ is a sphere, obtained by gluing a disc and its mirror image along their boundaries.
Conformal field theory, boundary conditions and applications to string theory
Since S1 is a disc, it follows by induction that Si is a disk, and in particular, Sk−1 is a disc.
Determining the Genus of a Map by Local Observation of a Simple Random Process
For, a sequence of functions holomorphic and bounded in an open disc, which is a Cauchy sequence in the sup norm, converges to a bounded holomorphic function in the same disc.
Duality in quantum information manifolds
This orientation is what we would expect for a binary system in which the compact ob ject is surrounded by an accretion disc; such a disc ejects material perpendicularly as a result of some form of instability, either in the disc or in the mass transfer rate.
A radio jet in the prototypical symbiotic star Z And?
Although there is a strong correlation between nearinfared excess and other disc indicators, the absence of a near infrared excess does not necessarily imply the absence of an accretion disc.
Evidence for high accretion-rates in Weak-Line T Tauri stars?
In at least some of these cases it is tempting to explain the failure of the accepted paradigm by stating that WTTs may or may not have discs, but that these discs are currently not accreting onto the central star.
Evidence for high accretion-rates in Weak-Line T Tauri stars?
For a Keplerian accretion disc the disc thickness is H ∼ c/Ω, and thus this approximation implies that λ ≪ H .
Kinetic theory viscosity
Keeping this in mind, the following definition may be viewed as combinatorial. A combinatorial surface is a 2-complex representing some surface. A combinatorial sphere and a combinatorial disc are 2-complexes representing a sphere and a disc respectively.
Diagrams with Selection and Method for Constructing Boundedly Generated and Boundedly Simple Groups
Every combinatorial sphere and every combinatorial disc are finite (because of the compactness of spheres and discs).
Diagrams with Selection and Method for Constructing Boundedly Generated and Boundedly Simple Groups
Remark 2.3. A disc map is simple if and only if its underlying 2-complex is a combinatorial disc.
