Penrose Process

In the traditional theory, it is impossible to produce superradiation in a straight time and space without a Penrose process. We know that similar entities can be artificially created by formulas that exist in the algebraic field. We have found that when a certain potential is created, there will be a superradiation phenomenon without the Penrose process in flat space and time.

Space and Time in Isaac Barrow

Space And Time

This chapter explores Isaac Barrow’s account of time and space. Barrow’s account is important, partly because it is often argued to be one of the sources that Newton drew on in constructing his absolutism. Although Barrow is usually read as a pre-Newtonian absolutist, this chapter argues that Barrow is in fact a modal relationist, identifying space and time with the relational modes of bodies. This new reading entails that Barrow’s account of time may not have played as large a role in the development of Newton’s work as has been thought, but it also raises the possibility that Leibniz drew on Barrow’s relationism.

A hipótese discutida na pesquisa (ainda inconclusa) que dá origem a este texto é a de que as formalizações matemáticas da Teoria Geral do Emprego, dos Juros e da Moeda, elaboradas por Roy HARROD, John HICKS e James MEADE, além das de David CHAMPERNOWNE e de Brian REDDAWAY, ainda que semelhantes na forma final, foram alcançadas mediante diferentes raciocínios, justificativas e argumentos teóricos, e que a aceitação e o sucesso da versão matematizada se deu pelo fato dela permitir a incorporação – de modo implícito – das variadas relações de causalidade definidas por cada um destes autores. Por razões de tempo e de espaço, o texto explora esta hipótese de forma ainda preliminar e cinge-se apenas à contribuição de HARROD. Abstract The hypothesis behind the ongoing research that motivates this paper suggests that the mathematical formalizations of the General Theory of Employment, Interest and Money advanced by Roy HARROD, John HICKS and James MEADE, as well as the ones by David CHAMPERNOWNE and Brian REDDAWAY, although similar in their form, were constructed using different kinds of reasonings, justifications and theoretical arguments. Consequently, the acceptance and success of the mathematized version occurred because it allowed the – implicit – incorporation of the diverse causal relations proposed by each of these authors. Lack of space and time prevent a complete development of this hypothesis here, so this text focuses only on HARROD’s contribution.

The article examines peculiarities of the use of parentheses in A. Belyi's lyrics and prose. The author describes the main aspects of analysing parentheses in modern linguistics: description of their functional features, their link with the main body of the statement, parentheses as text forming means, time and space organization of the text, realization of the author's irony, means of conveying evaluative information, ways of comparing, metatextual comment, informative actualization, means of creating a dialogue in a fiction text, usage parentheses in particular genres. This study identifies the most characteristic functions of parentheses in A. Belyi's texts, the connection of parentheses with different textual levels and their role in the overall structure of the literary text. Both the most typical and unique functions of parentheses in A. Belyi's works are described in detail. The main functional features of parentheses are defined in terms of space and time organization of the text and the interaction of various informative and subjective speech plans of the text. The article outlines the main aspects of language game within the framework of parentheses, as well as the means of interaction between the parentheses and the main context, presented in the poetry and prose of A. Belyi. The analysis suggests that the most typical functions of the parentheses in A. Belyi's works are detailed portrayal of the character, switching space and time registers, making comparisons, clarification, and conveying emotional and evaluative information.

The universe, the space that make up their basis planets in it, their creation, the main essence of their creation, form, composition, meaning, movements, interactions, their influence on human life and activities, the role of man in the universe and in life on Earth, life, the criteria of activity and processes occurring in time and space have long been of interest to humanity. One of the main problems in the history of philosophy is the question of space and time. This problem was defined in different ways in the great schools of thought by thinkers of different periods. One of these great thinkers is Alisher Navoi. Navoi's works, along with other socio-philosophical themes, uniquely express and analyze the problems of the firmament and time. Its main feature is that it is based on the divine (pantheistic) religion, Islam, its holy book, the Koran and other theological sources, as well as on the secrets of nature and the Universe, the main miracle of Allah - human intelligence, the power of enlightenment, they are the key revealing all these secrets.

Moving forward, this chapter explores ways of sharing learning, as the basis for building solidarity across time and space. The first example comes from India, as workers and communities shared their research on industrial malpractices, leading to the human and environmental disaster, when more than 40 tons of methyl isocyanate gas from a pesticide plant in Bhopal, India. Research findings and experiences were shared across the globe, supporting Indian communities in their struggles for justice and a safer environment. The second example comes from London’s Docklands where communities and local workforces shared their learning over the years, developing the case for alternative approaches to planning, sharing ideas about redevelopment to meet people’s needs rather than to promote private profitability.

Full Classification

If two particles collide near a rotating black hole, their energy in the centre of mass frame can become unbounded under certain conditions. In doing so, the Killing energy [Formula: see text] of debris at infinity is, in general, remain restricted. If [Formula: see text] is also unbounded, this is called the super-Penrose process. We elucidate when such a process is possible and give full classification of corresponding relativistic objects for rotating space-times. We also discuss the case of a pure electric super-Penrose process that is valid even in the flat space-time. The key role in consideration is played by the Wald inequalities.

Out of a total of 1025 twin births occurring in 11 South Moravian districts from 1972 to 1976, 638 occurred in the same time and space interval (P = 0.00037). The observed clustering suggests the existence of environmental factors influencing twinning rates.

Shed Light

In this study, we investigate how quantification of Wikipedia biographies can shed light on worldwide longitudinal gender inequality trends, a macro-level dimension of human development. We present the Wikidata Human Gender Indicator (WHGI), located within a set of indicators allowing comparative study of gender inequality through space and time, the Wikipedia Gender Indicators (WIGI), based on metadata available through the Wikidata database. Our research confirms that gender inequality is a phenomenon with a long history, but whose patterns can be analyzed and quantified on a larger scale than previously thought possible. Through the use of Inglehart–Welzel cultural clusters, we show that gender inequality can be analyzed with regard to world’s cultures. We also show a steadily improving trend in the coverage of women and other genders in reference works.

The article explores the meaning and usages of "communicative and cultural memory" in the context of "mental maps". It looks particularly at theories which, on the basis of constructed symbolic divisions (such as "Europe" vs. "Balkans"), connote a "lasting Balkan/European reality". The explication focuses on the content considered by these theories as specifically Balkan (or specifically Serbian) understanding of the concepts of Space and Time.
