  • Interesting fact: Not all polar bears hibernate; only pregnant females polar bears do
    • Polarization (Opt) A peculiar affection or condition of the rays of light or heat, in consequence of which they exhibit different properties in different directions.
    • Polarization (Elec) An effect produced upon the plates of a voltaic battery, or the electrodes in an electrolytic cell, by the deposition upon them of the gases liberated by the action of the current. It is chiefly due to the hydrogen, and results in an increase of the resistance, and the setting up of an opposing electro-motive force, both of which tend materially to weaken the current of the battery, or that passing through the cell.
    • Polarization The act of polarizing; the state of being polarized, or of having polarity.

  • Interesting fact: Polar bears are excellent swimmers. They have been known to swim more than 60 miles without a rest
    • n polarization The state, or the act producing the state, of having, as a ray, different properties on its different sides, so that opposite sides are alike, but the maximum difference is between two sides at right angles to each other. This is the case with polarized light.
    • n polarization Less properly, the acquisition of polarity, in any sense. Also spelled polarisation.
    • n polarization The condition thus produced. Thus, in the electrolysis of water polarization of the electrodes takes place, the one becoming coated with a film of oxygen, the other with a film of hydrogen gas. The phrase is most frequently used to describe the process by which the negative plate in a voltaic cell becomes coated with hydrogen, with the result of giving rise to a reverse electromotive force, and thus of weakening the current. On the methods of preventing this, see cell, 8.
    • n polarization In geometry, the passing to or taking the polar: of two polar figures or formulas either results from the other by polarization.
    • n polarization In biology, the replacement or regeneration of lost parts in the axial or stere-ometrical relations which they exhibited before they were lost. See polarity, 1 .
    • n polarization In electricity, the property of acting differently according as the current, electric or magnetic, is in one direction or the opposite direction.

In science:

However, polarization is quite difficult to transmit through a telecommunications fiber, which generally acts as a “polarization scrambler. ” Thus an important part of the Mark 1 Entangled System design is its polarization control.
Current status of the DARPA Quantum Network
The interstellar origin of this polarization was indicated by the correlation of the degree of polarization with reddening and the fact that the direction of polarization is generally parallel to the galactic plane.
Interstellar Grains -- The 75th Anniversary
With the symmetrical polarization curves as shown in Fig.1, such small signal can be determined with much better accuracy than previously reported results, where input polarization were only varied between 0◦ to 90◦ .9,12 The polarization data with full 360◦ scan range also provides another advantage.

The polarization properties of the wave are described by the remaining parameters: Q and U describe linear polarization, while V describes circular polarization.
The CMB polarization: status and prospects
For instance, the usual approach to the Faraday rotation of CMB polarization is to assume that the polarization itself is only due to the adiabatic mode while the rotation of the polarization plane is only due to the magnetic field.

In particular, we discuss the status of the nucleon spin structure, transverse polarized asymmetries, and recent developments such as DVCS, polarized fragmentation and polarized resummation.

The gluon polarization obtained by COMPASS from high-pT hadron pairs and open charm production, compared to SMC and HERMES determinations from highpT hadron pairs. of the first moment of all polarized light quark and antiquark densities, as well as of the polarized gluon density, that mixes in the singlet.
Spin Physics
The COMPASS experiment has measured both longitudinal and transverse polarization transfers of Λ and ¯Λ production.26 By averaging over the target polarization, they determine the polarized fragmentation functions, ∆DΛ/q (zh ).
Spin Physics
While optical polarization measurements are necessarily limited to the lowextinction parts of a cloud, so the background stars are still bright enough to have their polarization measured, IR polarization data could in principle sample more opaque regions and therefore provide a deeper view of the inner magnetic field.
