We discuss the concepts of Weyl and Riemann frames in the context of metric theories of gravity and state the fact that they are completely equivalent as far as geodesic motion is concerned. We apply this result to conformally flat spacetimes and show that a new picture arises when a Riemannian spacetime is taken by means of geometrical gauge transformations into a Minkowskian flat spacetime. We find out that in the Weyl frame gravity is described by a scalar field. We (...) give some examples of how conformally flat spacetime configurations look when viewed from the standpoint of a Weyl frame. We show that in the non-relativistic and weak field regime the Weyl scalar field may be identified with the Newtonian gravitational potential. We suggest an equation for the scalar field by varying the Einstein-Hilbert action restricted to the class of conformally-flat spacetimes. We revisit Einstein and Fokker’s interpretation of Nordström scalar gravity theory and draw an analogy between this approach and the Weyl gauge formalism. We briefly take a look at two-dimensional gravity as viewed in the Weyl frame and address the question of quantizing a conformally flat spacetime by going to the Weyl frame. (shrink)

The coronavirus disease pandemic fundamentally disrupted humans’ social life and behavior. Public health measures may have inadvertently impacted how people care for each other. This study investigated prosocial behavior, its association well-being, and predictors of prosocial behavior during the first COVID-19 pandemic lockdown and sought to understand whether region-specific differences exist. Participants from eight regions clustering multiple countries around the world responded to a cross-sectional online-survey investigating the psychological consequences of the first upsurge of lockdowns in spring 2020. Prosocial behavior (...) was reported to occur frequently. Multiple regression analyses showed that prosocial behavior was associated with better well-being consistently across regions. With regard to predictors of prosocial behavior, high levels of perceived social support were most strongly associated with prosocial behavior, followed by high levels of perceived stress, positive affect and psychological flexibility. Sociodemographic and psychosocial predictors of prosocial behavior were similar across regions. (shrink)

The book provides clear, step-by-step procedures to help you decide for yourself what to believe--to be (...) a consumer of information in our contemporary "world of experts.". (shrink)

John Burdon Sanderson Haldane was a giant among men. He made major contributions to genetics, population biology, and evolutionary theory. He was at once comfortable in mathematics, chemistry, microbiology and animal physiology. But it was his belief in education that led to his preparing his popular essays for publication. In his own words: "Many scientific workers believe that they should confine their publications to learned journals. I think that the public has a right to know what is going on inside (...) the laboratories, for some of which it pays." So begins Haldane's collection of essays, perhaps the most public intellectual communicating science before the writings of Stephen Jay Gould. The first part of the volume emphasizes the important developments in biology and natural science in the first quarter of the century. As such, it provides a benchmark for studies of the next three quarters of the century. In an unusual introduction, Price takes the readers through their paces, discussing the situation then and now in vitamins, oxygen want, disease controls, and the rewards of science as such. This is followed by Haldane's views on society, art, religion and economy as seen through the eyes of a politically alert major scientist. The editor provides readers unfamiliar with Haldane with a carefully rendered chronology of a life that began in 1892 and that spanned much of the present century. Despite ideas on race, class and politics that have seen better times, Haldane was truly exceptional in translating the science of his time into ideas that "everyman" could readily grasp. His predictions on what science would achieve were on target far more often than not. But even his failed predictions are perhaps the most interesting of all. They throw into sharp relief the truly novel and revolutionary developments in science over the past 75 years. J.B.S. Haldane held many positions and received many honors during his lifetime. But for most of the period covered in this volume, he was the William Dunn Reader in Biochemistry at Cambridge University. He simultaneously served as Fellow of New College, in Oxford University's Horticultural Institute. Carl A. Price served until 1999 as professor IIof plant molecular biology in the Waksman Institute of Microbiology at Rutgers, the State University of New Jersey. He also served as the editor of Plant Molecular Biology Reporter from 1983 until 1997. This is the first volume in a new series on the history and theory of science. (shrink)

Reasoning under uncertainty, that is, making judgements with only partial knowledge, is a major theme in artificial intelligence. Professor Paris provides here an introduction to the mathematical foundations of the subject. It is suited for readers with some knowledge of undergraduate mathematics but is otherwise self-contained, collecting together the key results on the subject, and formalising within a unified framework the main contemporary approaches and assumptions. The author has concentrated on giving clear mathematical formulations, analyses, justifications and consequences of the (...) main theories about uncertain reasoning, so the book can serve as a textbook for beginners or as a starting point for further basic research into the subject. It will be welcomed by graduate students and research workers in logic, philosophy, and computer science as a textbook for beginners, a starting point for further basic research into the subject, and not least, an account of how mathematics and artificial intelligence can complement and enrich each other.

Little is in print on the development in Britain of university disciplines including the academic study of education. This paper provides a historical narrative of the study of adolescence from the 1870 Education Act to the contemporary day. Adolescence textbooks are examined in the context of changes in the education system, such as the demand for secondary education and the expansion of teacher education. Changing emphases in adolescence research are traced through various publications to illustrate curriculum developments. The important contributions (...) of Dame Olive Wheeler, Professor W. D. Wall and other leading writers on adolescence are evaluated. It is clear that in over a century of national educational provision British teachers have never faced a great choice of adolescence texts and the paper concludes with some reflections on this observation.

Introduction.--Dualism and the new problem.--Truth and experience.--Plan and stages of the argument.--The interpretation of sense-experience: and of perceptual experience.--Understanding and the world of noumena and phenomena.--Self-conscious experience.--The sphere of reason, scientific experience.--The sphere of finite spirit, moral experience.--The sphere of absolute spirit, religious experience, contemplation.

J. B. Schneewind's "The Invention of Autonomy" has been hailed as a major interpretation of modern moral thought. Schneewind's narrative, however, elides several serious interpretive issues, particularly in the transition from late medieval to early modern thought. This results in potentially distorted accounts of Thomas Aquinas, Hugo Grotius, and G. W. Leibniz. Since these thinkers play a crucial role in Schneewind's argument, uncertainty over their work calls into question at least some of Schneewind's larger agenda for the history of ethics.

"The Laws", Plato's most lengthy dialogue, has longbeen regarded as the most comprehensive explanation of the possible consequences of a practical application of his philosophy.We might expect the first question Plato ponders to be "What is Law?" Instead, the question posed is "Who is given the credit for laying down your laws?"We are privy to an interaction between a powerfulstatesman and an Athenian philosopher on theisland of Crete. We watch as a plan for a new political order is worked out (...) that embodiesmany of the issues that we still struggle withtoday, such as the status of women, the statusof homosexuals, the family, criminal law, andthe role of religion in a healthy society.We at Timeless Classic Books hope that you enjoy this ancient thought-provoking story that may change the way you think about modern day issues.(Timeless Classic Books).

Excerpt from Studies in Human Nature The aim of these studies is to examine with all possible freedom from theoretical bias some phases of human nature which are of great interest in themselves, and in the light of the analysis to draw certain conclusions. It would have been natural to have included in such a series the consideration of certain other aspects of human nature, more especially those which concern morality and civic institutions. Morality and the conditions of citizenship arc (...) in many ways the most important forms of human life which can engage our attention at the present time; and the influence of the recent upheaval in our experience has brought before us many moral problems with a peculiar, and perhaps even a new', prominence. It has seemed better, however, to reserve the consideration of these and kindred subjects for another occasion. It is not the purpose of these papers to defend or support any of the familiarly accepted theories, whether of idealism or realism. Human nature is far more interesting and much more important than any theory, and on that account perhaps is tolerant of many theories. It may be remarked, however, that the momentum which carried forward one peculiar form of idealism - the confident and confiding idealism of a generation ago - seems now to have spent its force; and that a realism which takes the form of a new materialism can hardly claim to be in a position to show a better way.

This is the fourth volume of the Clarendon edition of Robert Burton's Anatomy of Melancholy and the first of three volumes of Commentary. It contains commentary on the text up to p. 327 of volume one - i.e. The Argument of the Frontispeice, Democritus to the Reader, and Partition 1 as far as the end of Section 2, Member 3, Subsection 15: 'Misery of Schollers'. In his study of morbid psychology as it was understood in his day, Burton cites many (...) other writers. No previous edition of the Anatomy has identified all of these or verified all his quotations. In addition to explanatory notes and translations of all the passages in Latin, this edition attempts to locate all Burton's sources in the actual books he himself owned or to which he probably had access. The last of the three volumes of commentary will contain a Biobibliography listing over 1,500 authorities referred to by Burton, many very obscure, and will give not only bibliographical details but information about the writers.

A supertask is a task that consists in infinitely many component steps, but which in some sense is completed in a finite amount of time. Supertasks were studied by the pre-Socratics and continue to be objects of interest to modern philosophers, logicians and physicists. The term “super-task” itself was coined by J.F. Thomson (1954). Here we begin with an overview of the analysis of supertasks and their mechanics. We then discuss the possibility of supertasks from the perspective of general relativity.
