Gravity from a New Angle is a comprehensive analysis of fundamental concepts in Physics. Concepts like force, work, power and energy were developed over a period of centuries. In depth analysis of these concepts reveals that there is overlap in the way these concepts were defined. As a result, the concept of resultant force obscured the true understanding of energy interactions. Solution to most intriguing problems in Physics like Pioneer anomaly and unified theory relies on answers to the very basic questions. Does an object retain its mass when it collapses to a point mass? What is the amount of gravity at the center of the earth? In a chemical reaction between carbon and oxygen to form CO2, which atom releases the energy? Object gains mass or gravity when it collapses to a point size. Earth exerts enormous amount of gravity on an object kept at its center. Contrary to the wide spread belief, the energy in an combustion comes from the oxygen atom, which we should call as the fuel not the carbon atom. The flaws in fundamental concepts like the mass and force led our understanding of physical phenomenon in a wrong direction. By redefining these basic concepts in accordance with the observed facts, we can explain all the observed facts in an unified way. (Version 1.2)

The Feynman Lectures on Gravitation are based on notes prepared during a course on gravitational physics that Richard Feynman taught at Caltech during the 1962-63 academic year. For several years prior to these lectures, Feynman thought long and hard about the fundamental problems in gravitational physics, yet he published very little. These lectures represent a useful record of his viewpoints and some of his insights into gravity and its application to cosmology, superstars, wormholes, and gravitational waves at that particular time. The lectures also contain a number of fascinating digressions and asides on the foundations of physics and other issues.Characteristically, Feynman took an untraditional non-geometric approach to gravitation and general relativity based on the underlying quantum aspects of gravity. Hence, these lectures contain a unique pedagogical account of the development of Einstein's general theory of relativity as the inevitable result of the demand for a self-consistent theory of a massless spin-2 field (the graviton) coupled to the energy-momentum tensor of matter. This approach also demonstrates the intimate and fundamental connection between gauge invariance and the principle of equivalence.

Martin Simons, a passionate model pilot and multiple book author about the basics of model flying and aerodynamics, describes in an entertaining way why and how models fly in his book "Modellflug-ABC". With his clear and easy to understand language, he succeeds in summarizing even complex topics. For both beginners and advanced pilots, "Model Aviation ABC" is a valuable aid to understanding when and why models fly well, and how to use this knowledge to expand and refine your own flying skills. From the Content: In "Model Aviation ABC" the basics of aerodynamics (without mathematical deepening) are explained in connection with model flying, e.g. to clarify the effect of control reactions. What is the effect of a symmetrical or a semi-symmetrical airfoil? What triggers a stall and how do you recover the model? What makes a model stable and how do I achieve high stability? What is the importance of the propeller? Many questions that arise in the everyday life of model pilots are answered in the "Model Aviation ABC" in an explanatory way. The goal is to know and understand aerodynamic processes to set up and fly models well. Over 100 drawings illustrate the processes described in the text and round off the basics taught in the "Model Aviation ABC".

This festschrift was conceived in connection with the symposium 'Topics on Quantum Gravity and Beyond,' held in honor of Louis Witten. The majority of the essays deal with problems on the frontiers of quantum gravity and string theories. There are also articles on atomic, nuclear, and particle physics, to name a few.
