Well-liked growth in technological know-how is necessarily linked to controversies. therefore, younger researchers, particularly, need to the way to persevere through the interval of controversy and fight for attractiveness. regrettably, the abilities wanted will not be taught in textbooks or monographs, which usually describe the consensus of up to date experts.This ebook, that is in line with my very own studies as a scientist, describes the background of the development made in auroral technological know-how and magnetospheric physics via offering examples of rules, controversies, struggles, recognition, and good fortune in a few instances.Although no normal technique (if any exists) is pointed out, i am hoping that the reader will find out about the background of development in auroral technology and examples (right or mistaken) of facing the controversies.

Example text

As a result, many phenomena are rediscovered every sunspot cycle. Fault predictions of a great auroral display after a major solar activity are still issued from time to time without taking into account Newton’s results. 2. The Chapman–Ferraro Theory Chapman took up a theoretical study of the interaction between Maunder’s stream and the Earth’s dipole field. Chapman and his graduate student Vincenzo Ferraro recognized that Maunder’s stream should be treated as what we today call plasma, not a swarm of protons (or electrons).

Actually, Chapman was considerably encouraged when he learned that the Explorer 12 satellite crossed the magnetopause in 1962, and demonstrated that the magnetic field just inside the magnetopause is close to twice that of the dipole field value, as expected from the Chapman–Ferraro theory. This satellite observation event is described in detail by Larry Cahill (1997). I recall that Chapman mentioned that it is rather rare that a theory becomes confirmed more than 30 years after its inception. He was all the more convinced that a theory explaining the main phase must be an extension of the Chapman– Ferraro theory.

Two types of geomagnetic storms that begin with SSC of similar magnitudes. Left: Storms with an intense main phase (HO: the Honolulu record) and polar magnetic substorms (CO: the College record); Right: Storms with weak or no appreciable main phase and substorms. -I. and S. Chapman, J.
