On Art and Science: Tango of an Eternally Inseparable Duo (The Frontiers Collection)
by Shyam Wuppuluri Dali WuEinstein once remarked "After a certain high level of technical skill is achieved, science and art tend to coalesce in aesthetics, plasticity, and form. The greatest scientists are always artists as well". In this volume, some of the world’s leading thinkers come together to expound on the interrelations between sciences and arts. While one can segregate art and place it outside the scientific realm, it is, nevertheless, inextricably linked to our essential cognitive/emotional/perceptual modalities and abilities, and therefore lies alongside and in close contact with the method of science and philosophy. What inspiration can scientists draw from art and how can scientific spirit foster our understanding and creation of aesthetic works? How are art and science grounded in our cognition? What role does perception play in science and art? Are criteria for beauty in art and science the same? How does evolution shape our understanding of art? How do science, art and scientifico-artistic frameworks shape society as a whole and help us address its pressing issues? The epistemological and ontological aspects haunt artists, philosophers and scientists alike. The essays in this volume address these manifold questions while also elucidating the pragmatic role they play in our daily life.
On Being Certain: Believing You Are Right Even When You're Not
by Robert A. BurtonBurton challenges the notions of how we think about what we know. He shows that the feeling of certainty we have when we know something comes from sources beyond our control and knowledge. In fact, certainty is a mental sensation, rather than evidence of fact. Because this feeling of knowing seems like confirmation of knowledge, we tend to think of it as a product of reason. But an increasing body of evidence suggests that feelings such as certainty stem from primitive areas of the brain and are independent of active, conscious reflection and reasoning. The feeling of knowing happens to us; we cannot make it happen.
On Being Certain: Believing You Are Right Even When You're Not
by Robert A. BurtonYou recognize when you know something for certain, right? You "know" the sky is blue, or that the traffic light had turned green, or where you were on the morning of September 11, 2001--you know these things, well, because you just do.In On Being Certain, neurologist Robert Burton challenges the notions of how we think about what we know. He shows that the feeling of certainty we have when we "know" something comes from sources beyond our control and knowledge. In fact, certainty is a mental sensation, rather than evidence of fact. Because this "feeling of knowing" seems like confirmation of knowledge, we tend to think of it as a product of reason. But an increasing body of evidence suggests that feelings such as certainty stem from primitive areas of the brain, and are independent of active, conscious reflection and reasoning. The feeling of knowing happens to us; we cannot make it happen.Bringing together cutting edge neuroscience, experimental data, and fascinating anecdotes, Robert Burton explores the inconsistent and sometimes paradoxical relationship between our thoughts and what we actually know. Provocative and groundbreaking, On Being Certain, will challenge what you know (or think you know) about the mind, knowledge, and reason.
On Being Reformed: Debates over a Theological Identity (Christianities in the Trans-Atlantic World)
by D. G. Hart Crawford Gribben Matthew C. Bingham Chris Caughey R. Scott ClarkThis book provides a focus for future discussion in one of the most important debates within historical theology within the protestant tradition - the debate about the definition of a category of analysis that operates over five centuries of religious faith and practice and in a globalising religion. In March 2009, TIME magazine listed ‘the new Calvinism’ as being among the ‘ten ideas shaping the world.’ In response to this revitalisation of reformation thought, R. Scott Clark and D. G. Hart have proposed a definition of ‘Reformed’ that excludes many of the theologians who have done most to promote this driver of global religious change. In this book, the Clark-Hart proposal becomes the focus of a debate. Matthew Bingham, Chris Caughey, and Crawford Gribben suggest a broader and (they argue) more historically responsible definition for ‘Reformed,’ as Hart and Scott respond to their arguments.
On Beyond Uranium: Journey to the End of the Periodic Table (Science Spectra)
by Sigurd HofmannIn the early nineteenth century chemists knew of the existence of ninety-two chemical elements, from Hydrogen to Uranium. For nearly forty years scientists thought they knew the content of our planet and all of its contents. In the late 1930s the world of chemical science began to discover elements beyond Uranium - the 'transuranics'. These new, super-heavy elements are probably not found in nature at all but can be detected, if only for a few fractions of a second, in precisely designed experiments using powerful nuclear tools. On Beyond Uranium: Journey to the End of the Periodic Table is full of exciting new concepts and tells the story of the author's quest to discover elements never before known to man.
On Breathing: Care in a Time of Catastrophe
by Jamieson WebsterA gorgeous, expansive piece of narrative non-fiction about care, dependence, and what it means to breathe in an age of environmental catastropheA few moments after birth we begin to use our lungs for the first time. From then on, we must continue breathing for as long as we are alive. And although this mostly happens unconsciously, in a society plagued by anxiety, climate change, environmental racism, and illness, there are more and more instances that &“teach us about the privilege that is breathing.&” Why do we so easily forget the air that we breathe in common? What does it mean to breathe when the environment that sustains life now threatens it? And how can life continue to flourish under conditions that are increasingly toxic? To approach these questions, Jamieson Webster draws on psychoanalytic theory and reflects on her own experiences as an asthmatic teenager, a deep-sea diver, a palliative psychologist during COVID, a psychoanalyst attentive to the somatic, and a new mother. The result is a compassionate and timely exploration of air and breathing as a way to undo the pervasive myth of the individual by considering our dependence on invisible systems, on one another, and the way we have violently neglected this important aspect of life.
On Capitalism and Inequality: Progress and Poverty Revisited (Springer Praxis Bks.)
by Robert U. AyresCapitalism is under attack. Defenders say that capitalism has raised billions of people from poverty. But a central activity of capitalism today, Wall Street style, is speculation (gambling), using other people’s money, and privatizing the profits while socializing the debts. Skeptics argue that capitalism has redistributed the wealth of the planet in favor of a very few, meanwhile leaving the planet in bad shape and leaving billions of people out in the cold. Wealth is now extremely mal-distributed, opportunity is far from equal, and upward social mobility has declined significantly in recent decades. This book reviews the evidence and arguments pro and con in considerable detail.The evidence is mixed. The main virtue of capitalism is its emphasis on competition as a driver of innovation and, thus, of economic growth. It is true that economic growth has accelerated in recent centuries, and it is true that billions of people have been lifted from poverty. But it is not necessarily true that intense “winner take all” competition in the marketplace is the explanation for growth. Neoclassical economic theory posits that self-interest is the primary motive for all economic decisions, leaving little room for cooperation and even less for altruism. The theory applies to an unrealistic “model” of human behavior, known as Homo economicus or “economic man”, whose characteristic activity is buying or selling.The reason for using the adjective word “social” – as in socialism” or “social service” or “social democracy” -- is, essentially, to deny those postulates of standard economic theory. Real humans are not rational utility maximizers (whatever that is) and very often do things that are not in their own personal best interests. This can happen because other interests, such as family loyalty, professional, religious, or patriotic duty, may take precedence. Real people rarely behave like Homo economicus, who has rivals but no friends. He (or she) does not trust anyone, hence cannot cooperate with others, and can never create, or live in, a viable social system (or marriage). Yet social systems, ranging from families and tribes to firms, cities, and nations do (and must) exist or civilization cannot exist. A viable social system must not allow “winner takes all”. It must reallocate some of the societal wealth being created by competitive activities to support the young, the old and the weak, because all of those people have equal rights, if not the same luck or the same skills.Both competition and cooperation have important roles to play. A hybrid capitalism involving both is the only viable solution. The book ends with a specific suggestion, namely Universal Basic Income, or UBI.
On Coexistence Patterns: Hierarchies of Intricate Partially Symmetric Solutions to Stuart-Landau Oscillators with Nonlinear Global Coupling (Springer Theses)
by Sindre W. HauglandThis book is about coexistence patterns in ensembles of globally coupled nonlinear oscillators. Coexistence patterns in this respect are states of a dynamical system in which the dynamics in some parts of the system differ significantly from those in other parts, even though there is no underlying structural difference between the different parts. In other words, these asymmetric patterns emerge in a self-organized manner. As our main model, we use ensembles of various numbers of Stuart-Landau oscillators, all with the same natural frequency and all coupled equally strongly to each other. Employing computer simulations, bifurcation analysis and symmetry considerations, we uncover the mechanism behind a wide range of complex patterns found in these ensembles. Our starting point is the creation of so-called chimeras, which are subsequently treated within a new and broader context of related states.
