[6] [1] The founders are anonymous, [7] choosing to remain unknown or known only via usernames; the most prominent founder is commonly referred to as "Hausemaster".
This recursive ray tracing of reflective colored spheres on a white surface demonstrates the effects of shallow depth of field, "area" light sources, and diffuse interreflection. (c. 2008) In 3D computer graphics, ray tracing is a technique for modeling light transport for use in a wide variety of rendering algorithms for generating digital images.
The first X-ray picture of the Sun from a rocket-borne telescope was taken by John V. Lindsay of the NASA Goddard Space Flight Center and collaborators in 1963. The first orbiting X-ray telescope flew on Skylab in the early 1970s and recorded more than 35,000 full-disk images of the Sun over a 9-month period. [3]
Actinides easily react with halogens forming salts with the formulas MX 3 and MX 4 (X = halogen). So the first berkelium compound, BkCl 3 , was synthesized in 1962 with an amount of 3 nanograms. Like the halogens of rare earth elements, actinide chlorides , bromides , and iodides are water-soluble, and fluorides are insoluble.
