3. Earth's magnetic field - Wikipedia

   en.wikipedia.org/wiki/Earth's_magnetic_field

   The Earth's magnetic field is believed to be generated by electric currents in the conductive iron alloys of its core, created by convection currents due to heat escaping from the core. A schematic illustrating the relationship between motion of conducting fluid, organized into rolls by the Coriolis force, and the magnetic field the motion ...

   en.wikipedia.org/wiki/Van_Allen_radiation_belt

   The belts are named after James Van Allen, who published an article describing the belts in 1958. [1] [2] Earth's two main belts extend from an altitude of about 640 to 58,000 km (400 to 36,040 mi) [3] above the surface, in which region radiation levels vary. The belts are in the inner region of Earth's magnetic field.

   The company used the name widely in European advertising and later introduced it to the North American market with the Contour. The Zetec name was so widely recognized that Ford decided to apply it to other high-tech four-cylinder engines. It was used across many engine types in Europe even though the original Zeta design ended production in 2004.

7. Hankel contour - Wikipedia

   en.wikipedia.org/wiki/Hankel_contour

   In mathematics, a Hankel contour is a path in the complex plane which extends from (+∞,δ), around the origin counter clockwise and back to (+∞,−δ), where δ is an arbitrarily small positive number. The contour thus remains arbitrarily close to the real axis but without crossing the real axis except for negative values of x. The Hankel ...
