E-mail:[email protected] F abled in antiquity for its treasures of wisdom, the Library of Alexandria was the envy of the civilized world. Alexandria was by no means the first great book repository, but ...
متن کاملHow are glories formed?
Mie theory can be used to generate full-color simulations of atmospheric glories, but it offers no explanation for the formation of glories. Simulations using the Debye series indicate that glories are caused by rays that have suffered one internal reflection within spherical droplets of water. In 1947, van de Hulst suggested that backscattering (i.e., scattering angle theta = 180 degrees) coul...
متن کاملCan cirrus clouds produce glories?
A vague glory display was photographed over central Utah from an airplane beginning its descent through a cirrus cloud layer with an estimated cloud top temperature of -45 and -55 degrees C. Photographic analysis reveals a single reddish-brown ring of 2.5-3.0 degrees radius around the antisolar point, although a second ring appeared visually to have been present over the brief observation perio...
متن کاملGlories of protein structure
When the history of 20th century science is written, surely the chapter on determining the structure of molecules by X-ray crystallography, NMR, and electron microscopy will be one of the most prominent, with the structures of proteins and viruses being the culminating glory. No current book illustrates and explains these glories more effectively and concisely than Branden and Tooze’s second ed...
متن کاملAtmospheric glories: simulations and observations.
Mie theory can be used to provide full-color simulations of atmospheric glories. Comparison of such simulations with images of real glories suggests that most glories are caused by spherical water droplets with radii between 4 and 25 microm. This paper also examines the appearance of glories taking into account the size of the droplets and the width of the droplet size distributions. Simulation...
