The leading edge (defined by the stars Dubhe and Merak) is referenced to a clock face, and the true azimuth of Polaris worked out for different latitudes. The apparent motion of Polaris towards and, in the future, away from the celestial pole, is due to the precession of the equinoxes . [ 36 ]
Beta Cassiopeiae is the star's Bayer designation.It also bore the traditional names Caph (from the Arabic word كف kaf, "palm" – i.e. reaching from the Pleiades), Chaph and Kaff, as well as al-Sanam al-Nakah "the Camel's Hump". [10]
Baffin Island (formerly Baffin Land), [5] in the Canadian territory of Nunavut, is the largest island in Canada, the second-largest island in the Americas (behind Greenland), and the fifth-largest island in the world.
A speculative representation of Antarctica labelled as ' Terra Australis Incognita ' on Jan Janssonius's Zeekaart van het Zuidpoolgebied (1657), Het Scheepvaartmuseum The name given to the continent originates from the word antarctic, which comes from Middle French antartique or antarctique ('opposite to the Arctic') and, in turn, the Latin antarcticus ('opposite to the north').
CEP is not a good measure of accuracy when this distribution behavior is not met. Munitions may also have larger standard deviation of range errors than the standard deviation of azimuth (deflection) errors, resulting in an elliptical confidence region. Munition samples may not be exactly on target, that is, the mean vector will not be (0,0).
The Rosen chart is said to be comoving with our family of inertial nonspinning observers, because the coordinates ve − u, x, y are all constant along each world line, given by an integral curve of the timelike unit vector field =. Thus, in the Rosen chart, these observers might appear to be motionless.
The Philippines is an archipelago of 7,641 islands customarily enclosed by the lines demarcated by the Treaty of Paris in 1898 and its supplementary Treaty of Washington of 1900, and the Convention Between the United States and Great Britain in 1930, which came to be known in the Philippines as its International Treaty Limits.
In the mathematical field of differential geometry, a smooth map between Riemannian manifolds is called harmonic if its coordinate representatives satisfy a certain nonlinear partial differential equation. This partial differential equation for a mapping also arises as the Euler-Lagrange equation of a functional called the Dirichlet energy.
