Fragments Of Science: Festschrift For Mendel Sachs


Book Description

Professor Mendel Sachs's contributions have been wide-ranging and the lectures presented at the symposium honoring him on his retirement encompassed a broad spectrum — hence the title Fragments of Science. The topics covered include solar physics, quantum mechanics, crystallography, elementary particles, logic and philosophy, and the history of physics. Included also is a new poem by noted poet Robert Creeley, composed especially for the symposium.Harvey Breverman, an eminent artist and professor of art, attended the symposium and sketched the lecturers and recorded some of the material they presented (as seen from the eyes of an artist!). These remarkable drawings are reproduced in duotone throughout the volume. Post-banquet reminiscences of turbulent times at the university in the late 1960s by noted author and computer guru Cliff Stoll enliven the volume. T Y Wu and Sachs exchange greetings and comments regarding their discussions of the twin paradox in the 1970s. Sachs closes the volume with an illuminating autobiographical chapter.This is a highly stimulating volume and a feast for the eyes.




Quantum Mechanics and Gravity


Book Description

This book describes a paradigm change in modern physics from the philosophy and mathematical expression of the quantum theory to those of general relativity. The approach applies to all domains - from elementary particles to cosmology. The change is from the positivistic views in which atomism, nondeterminism and measurement are fundamental, to a holistic view in realism, wherein matter - electrons, galaxies, - are correlated modes of a single continuum, the universe. A field that unifies electromagnetism, gravity and inertia is demonstrated explicitly, with new predictions, in terms of quaternion and spinor field equations in a curved spacetime. Quantum mechanics emerges as a linear, flatspace approximation for the equations of inertia in general relativity.




Physics of the Universe


Book Description

This book presents a new approach to the subject of cosmology. It fully exploits Einstein's theory of general relativity. It is found that the most general formal expression of the theory replaces the (10-component) tensor formalism with a (16-component) quaternion formalism. This leads to a unified field theory, where one field incorporates gravitation and electromagnetism. The theory predicts an oscillating universe cosmology with a spiral configuration. Dark matter is explained in terms of a sea of particle-antiparticle pairs, each in a particular (derived) ground state. This leads to an explanation for the separation between matter and antimatter in the universe. There is a brief discussion of black holes and pulsars. The final chapter delves into philosophical considerations such as the different types of 'truth', positivism versus realism and a discussion of the role of the Mach principle in physics and cosmology.




Otto Neurath and the Unity of Science


Book Description

This volume critically reexamines Otto Neurath’s conception of the unity of science. Some of the leading scholars of Neurath’s work, along with many prominent philosophers of science critically examine his place in the history of philosophy of science and evaluate the relevance of his work for contemporary debates concerning the unity of science.

Wave Forms


Book Description

In this daring book, the author proposes that artistic and literary forms can be understood as modulations of wave forms in the physical world. By the phrase "natural syntax," he means that physical nature enters human communication literally by way of a transmitting wave frequency. This premise addresses a central question about symbolism in this century: How are our ideas symbolically related to physical reality? The author outlines a theory of communication in which nature is not reached by reference to an object; rather, nature is part of the message known only tacitly as the wavy carrier of a sign or signal. One doesn't refer to nature, even though one might be aiming to; one refers with nature as carrier vehicle. The author demonstrates that a natural language of transmission has an inherent physical syntax of patterned wave forms, which can also be described as certain "laws of form"—a phrase used by D'Arcy Thompson, L. L. Whyte, Noam Chomsky, and Stephen Jay Gould. He describes a syntax inherent in natural languages that derives from the rhythmic form of a propelling wave. Instead of the "laws" of a wave's form, however, the author speaks of its elements of rhythmic composition, because "rythmos" means "wave" in Greek and because "composition" describes the creative process across the arts. In pursuing a philosophy of rhythmic composition, the author draws on cognitive science and semiotics. But he chiefly employs symmetry theory to describe the forms of art, and especially the patterns of poetry, as structures built upon the natural syntax of wave forms. Natural syntax, it turns out, follows a fascinating group of symmetry transformations that derive from wave forms.

The Natural Law of Cycles


Book Description

The Natural Law of Cycles assembles scientific work from different disciplines to show how research on angular momentum and rotational symmetry can be used to develop a law of energy cycles as a local and global influence. Angular momentum regulates small-scale rotational cycles such as the swimming of fish in water, the running of animals on land, and the flight of birds in air. Also, it regulates large-scale rotation cycles such as global currents of wind and water.James H. Bunn introduces concepts of symmetry, balance, and angular momentum, showing how together they shape the mobile symmetries of animals. Chapter 1 studies the configurations of animals as they move in a head-first direction. Chapter 2 shows how sea animals follow currents and tides generated by the rotational cycles of the earth. In chapter 3, Bunn explores the biomechanical pace of walking as a partial cycle of rotating limbs. On a large scale, angular momentum governs balanced shifts in plate tectonics.Chapter 4 begins with an examination of rotational wind patterns in terms of the counter-balancing forces of angular momentum. The author shows how these winds augment the flights of birds during migrations. A final chapter centres on the conservation of energy as the most basic principle of science. Bunn argues that in the nineteenth century the unity of nature was seen in the emergent concept of energy, not matter, as the source of power, including the movements of animals and machines. In each chapter Bunn features environmental writers who celebrate mobile symmetries. This book will interest students, naturalists, and advocates of the environmental movement.
