Isaak Newton (1642 - 1727). ... During 1665 - 1667 Newton made his three main discoveries: the method of fluxings and quadratures (differential and integral calculus, explanation of the light nature and the law of gravitation). ... In 1668 Newton built the first reflecting telescope. The big lens telescope gave indistinct image with painted edges. ... The scientist considered this problem indisolved and suggested a mean against chromatic aberration: a mirror must be used instead of objective lens. ...

... We guess it's almost impossible to create the site nowadays where all space relative philatelic materials (postage stamps, stationary, postal marks etc.) would be registered and presented. ... We tried to make such a step in April 2005, placing at the site first images of postage stamps with portraits of astronauts (cosmonauts, spacionauts, taikonauts:). ... All illustrative material (or simply speaking, all scans of stamps) are grouped in four sections: Countries , Years , Astronauts and Flights . ...

In the regular experiments carried out with the RAS radio telescopes at Pushchino during 1999-2002, the study of the radial dependence of scattering of compact natural radio sources was extended to remote regions of the solar plasma environment. ... The stream in the transalfvenic region displays the same typical radial structure as observed in the transonic region, i.e., the existence of a "precursor" - a narrow band of reduced scattering preceding a wide region of enhanced scattering. ...
