Big G


Book Description

The Newtonian constant of gravitation, G (often referred to as "big G"), is one of the most important of the universal fundamental physical constants. However, its value is the least well-determined of all such constants. This is because G is very difficult to measure reliably. Even though the gravitational force is responsible for star and galaxy formation on the massive scale of the universe, the force itself is minuscule on the tiny scale of the laboratory masses which must be used in the measurement. Consequently, its experimental value is prone to a high degree of inaccuracy. Moreover, it is the viewpoint of most physicists that G is not related to the other fundamental physical constants by any theory or understanding that is currently available. Therefore, it is thought that the value of G can only be obtained by measurement, and not from evaluating it in terms of other fundamental constants whose values are known with much greater precision and accuracy. The work presented in the book is an attempt to break through this mental barrier by demonstrating through numerical analysis that G is definitely related to the other fundamental constants. Consequently, it is possible to propose an exact value for G (to nine significant figures) that is obtainable from evaluation instead of from measurement.

The Gravitational Constant: Generalized Gravitational Theories and Experiments


Book Description

An up-to-date description of progress and current problems with the gravitational constant, both in terms of generalized gravitational theories and experiments either in the laboratory, using Casimir force measurements, or in space at solar system distances and in cosmological observations. Contributions cover different aspects of the state and prediction of unified theories of the physical interactions including gravitation as a cardinal link, the role of experimental gravitation and observational cosmology in discriminating between them, the problem of the precise measurement and stability of fundamental physical constants in space and time, and the gravitational constant in particular. Recent advances discussed include unified and scalar-tensor theories, theories in diverse dimensions and their observational windows, gravitational experiments in space, rotational and torsional effects in gravity, basic problems in cosmology, early universe as an arena for testing unified models, and big bang nucleosynthesis.

Gravitational Force of the Sun


Book Description

The correct interpretation of Kepler's third law is Gravitational force is equal to acceleration times the area: F = a .A. It is shown that the sequential mean distances of the planets from the center of the sun follow an exponential law, concluding that gravitation is quantized. New explanation and equation for eccentricity are presented. English translation of Foucault's papers on the pendulum and on the gyroscope

The Birth of Science


Book Description

This book reveals the multi-generational process involved in humanity's first major scientific achievement, namely the discovery of modern physics, and examines the personal lives of six of the intellectual giants involved. It explores the profound revolution in the way of thinking, and in particular the successful refutation of the school of thought inherited from the Greeks, which focused on the perfection and immutability of the celestial world. In addition, the emergence of the scientific method and the adoption of mathematics as the central tool in scientific endeavors are discussed. The book then explores the delicate thread between pure philosophy, grand unifying theories, and verifiable real-life scientific facts. Lastly, it turns to Kepler’s crucial 3rd law and shows how it was derived from a mere six data points, corresponding to the six planets known at the time. Written in a straightforward and accessible style, the book will inform and fascinate all aficionados of science, history, philosophy, and, in particular, astronomy.




What Goes Up... Gravity and Scientific Method


Book Description

The concept of gravity provides a natural phenomenon that is simultaneously obvious and obscure; we all know what it is, but rarely question why it is. The simple observation that 'what goes up must come down' contrasts starkly with our current scientific explanation of gravity, which involves challenging and sometimes counterintuitive concepts. With such extremes between the plain and the perplexing, gravity forces a sharp focus on scientific method. Following the history of gravity from Aristotle to Einstein, this clear account highlights the logic of scientific method for non-specialists. Successive theories of gravity and the evidence for each are presented clearly and rationally, focusing on the fundamental ideas behind them. Using only high-school level algebra and geometry, the author emphasizes what the equations mean rather than how they are derived, making this accessible for all those curious about gravity and how science really works.
