Some of the Chief Problems in Terrestrial Magnetism and Electricity.
the orderly arrangement of air densities and pressures demanded by gravity. The latter, on the other hand, as perpetually and continuously sets portions of the air in motion, in order to establish and maintain a state of equilibrium, which, however, is never attained. We must clearly recognize that the ceaseless complex changes in and motions of our atmosphere represent in fact the only state o...
متن کاملChapters in the History of Terrestrial Magnetism
1--The science of Terrestrial Magnetism is based on the fact that a magnet, free to move about its center of gravity, tends to assume a position of relative rest in an approximately definite direction with respect to the geographical meridian and the vertical at the place of observation. That it should do so must be due to the existence of a field of force which is known as the terrestrial magn...

l•In Chapter I* it was shown that the compass had been brought into use in northwestern Europe for the purposes of navigation by the year 1187, that its first mention in the literature of that year does not refer to it as being of recent introduction, that the discovery of the directive property of a magnet in the Earth's f•eld must have preceded this application by some considerable time, but ...
متن کاملGlycosides of hydroxyproline: some recent, unusual discoveries.
Glycosides of hydroxyproline (Hyp) in the plant cell wall matrix were discovered by Lamport and co-workers in the 1960s. Since then, much has been learned about these Hyp-rich glycoproteins. The intent of this review was to compare and contrast some less common structural motifs, in nontraditional roles, to uncover themes. Arabinosylation of short-peptide plant hormones is essential for growth,...
متن کاملTerrestrial Imaging Spectroscopy – Some Future Perspectives
This paper covers 60 years of terrestrial imaging spectroscopy or hyperspectral remote sensing – 30 years each devoted to past and future developments. For this purpose, a brief history of imaging spectroscopy is given, covering civilian airborne sensor and spaceborne mission developments and associated data processing capabilities. Moreover, the paper reviews the existing and planned space sys...
