# Oblique motion

## Definitions

• Webster's Revised Unabridged Dictionary
• Oblique motion (Mus) a kind of motion or progression in which one part ascends or descends, while the other prolongs or repeats the same tone, as in the accompanying example.

### In poetry:

My words and thoughts do both expresse this notion,
That Life hath with the sun a double motion.
The first Is straight, and our diurnall friend;
The other Hid, and doth obliquely bend.
"Colossians iii. 3. "Our Life Is Hid With Christ In God"" by George Herbert

### In science:

Transition from regular to chaotic motion in black hole magnetospheres
If λ is the axis of symmetry of the ﬂow, the four regimes are: rotation about λ, tumbling motion between λ and −λ, combination of rotation and tumbling, and preferential alignment with a direction oblique to λ.
Orientation of non-spherical particles in an axisymmetric random flow
It is given by the hul l in T (see the precise deﬁnition below) of Brownian motion, started from A, reﬂected with oblique angle π/3 (pointing ‘away’ from A) on [A,B] and [A, C ], and stopped when reaching [B, C ].

In particular, the law of KT − is that of the T -hull of a stopped Brownian motion with oblique reﬂection.
Critical exponents, conformal invariance and planar Brownian motion
Deﬁne a reﬂected Brownian motion (Bs, s ≥ 0) in H ′ with oblique reﬂection angle (angle π/3 on the part of the boundary between x and +∞ and reﬂection 2π/3 between −∞ and x) as the conformal image in H ′ of reﬂected Brownian motion in H .

Critical exponents, conformal invariance and planar Brownian motion
Earth’s orbital motion about the Sun, (α, δ) are the true right ascension and declination of the ob ject, Λ is the true solar longitude, ǫ is the obliquity of the ecliptic, and (∆α, ∆δ) are the change in apparent position in the sense apparent coordinate minus true coordinate (Lang 1986, and references therein).

Their result for the tidal contribution to the obliquity rate (0.00127 mas/yr) is much smaller than the 0.024 mas/yr found by Williams (1994) by a method based on the transfer of angular momentum between the rotational motion of the Earth and the orbital motion of the Moon keeping the total of the two constant.

Downstream of oblique termination shocks of pulsar winds, the Lorentz factor of bulk motion can be rather high even for low-sigma winds, up to γ = 5 for reasonably small inclination angles.
On the origin of variable gamma-ray emission from the Crab Nebula
Or in average the position of the heavenly body can be deduced by imagining it in uniform motion on a circle, (“the oblique circle that carries the planets along”, Dante, Par., X), with center on the Earth and rigidly attached to the sphere (“sky”) of the Fixed Stars, that in turn rotates uniformly around the Earth.
