... Всякую мероморфную функцию комплексного аргумента, например, многочлен, можно представлять себе как топологическое накрытие над сферой Римана, разветвленное над конечным множеством критических значений. Комбинаторика разветвленных накрытий играет важную роль в современной математической физике. ... Однако известные мне доказательства большинства из них требуют привлечения геометрических и топологических методов, далеко выходящих за рамки школьной математики. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...

In other words, by far most meteorites falling on Earth are chondrites. Finds are meteorites that were not seen to fall but were subsequently discovered on the ground, often long after they landed. ... The vast majority of meteorites in museum and private collections around the world are finds, not falls. ...

... From the uvby photometry and proper motions for about 5500 nearby F stars we have found the following: (i) F stars , taken in narrow ranges of metallicity , show at [fe/H] 0 rather distinct cut-off in their distribution along the Main Sequence (MS) at the blue side, which is suggested to be an indication for the MS turn-off in stellar groups of fixed metallicity ; (ii) the corresponding turn-off age from theoretical isohrones strongly correlates with the ...
