Political polarization. Political polarization (spelled polarisation in British English, African and Caribbean English, and New Zealand English) is the divergence of political attitudes away from the center, towards ideological extremes. [1] [2] [3] Scholars distinguish between ideological polarization (differences between the policy positions ...
Linearly polarized waves consist of photons that are in a superposition of right and left circularly polarized states, with equal amplitude and phases synchronized to give oscillation in a plane. [8] Polarization is an important parameter in areas of science dealing with transverse waves, such as optics , seismology , radio , and microwaves .
Van de Graaff generator. A Van de Graaff generator is an electrostatic generator which uses a moving belt to accumulate electric charge on a hollow metal globe on the top of an insulated column, creating very high electric potentials. It produces very high voltage direct current (DC) electricity at low current levels.

Political polarization is a prominent component of politics in the United States. [1] Scholars distinguish between ideological polarization (differences between the policy positions) and affective polarization (a dislike and distrust of political out-groups), both of which are apparent in the United States.
Why We're Polarized is a 2020 non-fiction book by American journalist Ezra Klein, in which the author analyzes political polarization in the United States.Focusing in particular on the growing polarization between the major political parties in the United States (the Democratic Party and the Republican Party), the author argues that a combination of good intentions gone wrong, such as dealing ...
Photon polarization. Photon polarization is the quantum mechanical description of the classical polarized sinusoidal plane electromagnetic wave. An individual photon can be described as having right or left circular polarization, or a superposition of the two. Equivalently, a photon can be described as having horizontal or vertical linear ...
Umpolung. In organic chemistry, umpolung ( German: [ˈʔʊmˌpoːlʊŋ]) or polarity inversion is the chemical modification of a functional group with the aim of the reversal of polarity of that group. [1] [2] This modification allows secondary reactions of this functional group that would otherwise not be possible. [3]
