In The Physical Sciences
- Polarization (waves), the orientation of oscillations in the plane perpendicular to a transverse wave's direction of travel which may include:
- Polarization (antenna), the orientation of electromagnetic waves from e.g. a radio antenna
- Dielectric polarization, charge separation in insulating materials:
- Polarization density, volume dielectric polarization
- Dipolar polarization, orientation of permanent dipoles
- Ionic polarization, displacement of ions in a crystal
- Maxwell-Wagner-Sillars polarization, slow long-distance charge separation in dielectric spectroscopy on inhomogeneous soft matter
- Polarization (electrochemistry), a change in the equilibrium potential of an electrochemical reaction
- Spin polarization, the degree by which the spin of elementary particles is aligned to a given direction
- Polarizability, an electrical property of atoms or molecules and a separate magnetic property of subatomic particles
- Polarization function, a feature of some molecular modelling methods
- Photon polarization, the mathematical link between wave polarization and spin polarization
- Vacuum polarization, a process in which a background electromagnetic field produces virtual electron-positron pairs
- Polarity in embryogenesis, during development, an embryo has an animal pole and a vegetal pole

“To survive there, you need the ambition of a Latin-American revolutionary, the ego of a grand opera tenor, and the physical stamina of a cow pony.”
—Billie Burke (1885–1970)
“Normally, the sciences distance themselves from life and the return to it via a detour.”
—Johann Wolfgang Von Goethe (1749–1832)
