Polar distance


  • Webster's Revised Unabridged Dictionary
    • Polar distance the angular distance of any point on a sphere from one of its poles, particularly of a heavenly body from the north pole of the heavens.

In literature:

In this triangle we have given the polar distance, P S = 10 deg.

On g g is a movable pivot, to which h, which determines the pole, k0 h being the polar distance.

This gave Butts time to increase the distance between them, but a man is no match for a polar bear in a race.

The Polar Distance of any point is its distance in arc from either pole.

In the measurement of equatorial co-ordinates, the polar distance is determined in an analogous way.

In news:

Readers who set out to read "South with the Sun," by the renowned cold-water distance swimmer Lynne Cox, will doubtlessly gear themselves up for an account of one of the greatest polar explorers ever.
Long-distance swimmer and author Lynne Cox traces the path of polar explorer Roald Amundsen – just in time for the centennial of his arrival at the South Pole.
I see my first polar bear from a distance of 300 feet - straight down.

In science:

In this case, due to the presence of the non-zero net charges, the colliders can be effectively polarized even being separated by a large distance, r ≫ Rat .
Relativistic effects in polarizational bremsstrahlung
Using a different analysis of polarization observation of radio galaxies, Nodland and Ralston found indication of anisotropy in electromagnetic propagation over cosmological distances with a birefringence scale of order 1025 m (i.e., about 0.1 - 0.2 Hubble distance). This gave ∆φ ~ 5 - 10 over Hubble distance).
Empirical Foundations of Relativistic Gravity
At a critical distance R = Rc the electronic response is no longer confined to a polarization within the surface but results in transfer of electrons into high lying states of the pro jectile.
Collisions of Slow Highly Charged Ions with Surfaces
Further information such as polarization measurements could even provide independent distance measurements between the observer and the explosive event (Sparks et al. 1999). A statistical estimate of the distribution of SN Ia relative to the structures in spiral galaxies will become possible as the sample size grows.

DG Tau’s bi-polar jet has meanwhile been identified in X-rays out to a distance of 5′′ from the star (G ¨udel et al. 2008).

The resulting artefacts affect I data but are more pronounced in Q and U images because the instrumental polarization rises rapidly with distance from the field centre (see Section 3.5).

We suggest that the W4 Polarization Arc may be at the same distance as the H ii complex, and it may be related to the star-formation activity there.

From the definition there follows easily that the multiplicative k>1 kδ(G,k), where δ(G, k) is the number of vertex pairs in G that are at distance k (see Eq. (5a) in (A196061). (c) The Wiener polarity index.

Obviously, taking other coefficients in the Wiener polynomial, one obtains generalized Wiener polarity indices (see ). (d) In one introduces a family of statistics on a connected graph G, based on the graph distances.
