Only after such classification we can make correct inferences about all DGPs. There exists yet another type of problem for complex systems. Here it is important to detect poss

This is the kind of (well known) story that is guaranteed to make every scientist—astronomer or otherwise—smile. By the 1860s Father Angelo Secchi was classifying stars according to their spectra and astronomical spectroscopy was born.

,Glowing Vortices—Accretion Disks, not quite so well known is that the hot gases which make up an accretion disk can produce emission lines of hydrogen and what’s more these emission lines can have very striking profile shapes. They are in fact often double-peaked with what’s called a central reversal in between; they also have broad extensive wings.
