When Karađorđe was killed by Miloš Obrenović, a feud between the two houses of Karađorđević and the Obrenović developed which lasted until the Obrenović King Alexander I was killed in 1903 with his family and the Karadjordjević returned to the throne.

As Bakunin's associate, James Guillaume, put it in his essay, Ideas on Social Organization ( 1876 ), " When ... production comes to outstrip consumption ... veryone will draw what he needs from the abundant social reserve of commodities, without fear of depletion ; and the moral sentiment which will be more highly developed among free and equal workers will prevent, or greatly reduce, abuse and waste.

When compared with the concept map ( which was developed by learning experts in the 1970s ) the structure of a mind map is a similar radial, but is simplified by having one central key word.

When ordered by temperature and when duplicate classes were removed, the spectral types of stars followed, in order of decreasing temperature with colors ranging from blue to red, the sequence O, B, A, F, G, K and M. ( A popular mnemonic for memorizing this sequence of stellar classes is " Oh Be A Fine Girl / Guy, Kiss Me ".

In the special case that M is a normal matrix, which by definition must be square, the spectral theorem says that it can be unitarily diagonalized using a basis of eigenvectors, so that it can be written for a unitary matrix U and a diagonal matrix D. When M is also positive semi-definite, the decomposition is also a singular value decomposition.

When using a film whose spectral sensitivity is not a good match to that of the light meter, for example orthochromatic black-and-white or infrared film, the meter may require special filters and re-calibration to match the sensitivity of the film.

When the spectral lines are absorption lines, the effect is called inverse Zeeman effect.
