Current scientific theories strive to find one theory, which would describe the origin of life on Earth, but so far none were successful. To succeed i this field, one has to broader their view and accompany the scientific question with philosophy and set firmly the framework of research and define its borders. In order to assess the philosophical part of the work, one needs not to resort to new ideas only, because men and women in the past have already expressed their thoughts. They are however nowadays remembered only in history of arts and philosophy. In our recent article published in Nature Astronomy, we presented a very complex model for the creation of methane and its reprocessing to more complex organic molecules including nucleic acid bases from simple gaseous precursors. The purpose of this work is to show the reoeating cycle of the creation of complex molecules from CO2 and their subsequent destruction back to their basic parent molecules in comparison with the idea of Hieronymus Bosch. and Svatopluk Civiš.
Various types of artificial ant nests (formicaries) are described. These include simple laboratory types to more complex formicaries whose esthetic design is suitable for flat interiors. Formicaries facilitate not only the observation of natural ant behaviour inside a nest, but also of the remarkable practices used by young queens to appropriate the nest of a host ant species. In such equipment it is even possible to arrange a predatory raid by slave-making ants and observe their behaviour inside the attacked nest. Such observations would not have been possible in natural conditions. and Pavel Amcha.
The article considers the writings of the sculptor Andreas Schweigl (1735-1812) and the painters Ignaz Chambrez (1758-1842) and Josef Heřman Agapit Gallaš (1756-1840). Around the year 1800, these three Moravian artists recorded their thoughts and insights in a number of texts that variously combined the traditional literary genre of artist’s biography with artistic topography, art criticism and a historical interpretation of early Moravian art and culture. Since all three were in some way connected with the new system of art education, the aim of this study is to examine whether and in what way standardized education affected not only their professional careers, but also their thinking. For all three, that thinking was rooted in a historical interpretation of the early art and culture of Moravia. All three discuss the function of art, artistic ideals, and to some extent the concept of the creative genius, as well as reflecting, directly or indirectly, on the theme of decadence as one stage in the cyclical view of history, in line with the paradigm of the age. The author sets out to compare their texts and in general terms show 1) how artists themselves viewed the importance of art education at the end of the 18 century; 2) how they responded to the changing role of the artist in society; and 3) how they defined artistic ideals and the artist’s social purpose. It is the wider implications of these changes in the artist’s social status, and in the function of art in Moravia and Central Europe generally, that form the primary focus of this study., Pavel Suchánek., and Obsahuje bibliografické odkazy
Ještěrky dokážou v nouzi odhodit svůj ocas a ten jim naroste. Axolotl mexický je schopen regenerovat celé orgány. Přeborníky jsou však ploštěnci - nejen že libovolné části jejich těl dorůstají, ale z odděleného kousku jejich organismu dokáže vyrůst celý nový jedinec. Takové regegnerační schopnosti lidský organismus nemá. Věda a medicína ale umí nahradit, či dokonce vylepšit stále více a více... and VIktor Černoch, Gabriela Adamková.
