Beyond Einstein... Are We All Afraid of the Truth?
smw-genart-02-06 Beyond Einstein ... Are we all afraid of the Truth? Sanjay M Wagh Central India Research Institute, Post Box 606, Laxminagar, Nagpur 440 022, India ∗ (Dated: March 20, 2006) Abstract The power-point presentation [1] provided herein shows exactly why Einstein’s field equations of his general relativity are based on an illogical approach to representing the observable world. Einstein had, in fact, discarded these equations way back in 1928 when he had began his solitary search for a unified field theory. However, the rest of us learned, taught, and also put too much faith for too long (for more than seventy years) in an illogical approach to representing the observable world. Consequently, we have developed great reluctance, resulting from dogmatic perceptions, prestige, reputation, ..., that is holding us back from orienting ourselves in the “right” direction to the understanding of the observable phenomena. This raises the question mentioned in the title: Are we all afraid of the Truth? Rhetorically speaking, we could then also ask: are we all afraid of Virginia Woolf? In the sequel, I also illustrate my approach to going Beyond Einstein for developing an appropriate mathematical framework for the fundamental physical ideas behind the General Principle of Relativity, for the unification of fundamental arXiv:physics/0603149v1 [physics.gen-ph] 20 Mar 2006 physical interactions and, hence, for a theory of everything. ∗Electronic address: cirinag˙[email protected] 1 The title of this article may appear only as an eye-catching one to some, repelling one to some others, a thought provoking one to few others .. -

Michelson–Morley Experiment
Michelson–Morley experiment Figure 1. Michelson and Morley's interferometric setup, mounted on a stone slab that floats in an annular trough of mercury The Michelson–Morley experiment was an attempt to detect the existence of the luminiferous aether, a supposed medium permeating space that was thought to be the carrier of light waves. The experiment was performed between April and July 1887 by Albert A. Michelson and Edward W. Morley at what is now Case Western Reserve University in Cleveland, Ohio, and published in November of the same year.[1] It compared the speed of light in perpendicular directions in an attempt to detect the relative motion of matter through the stationary luminiferous aether ("aether wind"). The result was negative, in that Michelson and Morley found no significant difference between the speed of light in the direction of movement through the presumed aether, and the speed at right angles. This result is generally considered to be the first strong evidence against the then-prevalent aether theory, and initiated a line of research that eventually led to special relativity, which rules out a stationary aether.[A 1] Of this experiment, Einstein wrote, "If the Michelson–Morley experiment had not brought us into serious embarrassment, no one would have regarded the relativity theory as a (halfway) redemption."[A 2]:219 Michelson–Morley type experiments have been repeated many times with steadily increasing sensitivity. These include experiments from 1902 to 1905, and a series of experiments in the 1920s. More recent optical -

Such quantities are called thermodynamic coordinates, variables or parameters. - Equilibrium: state of a macroscopic system in which all average properties do not change with time. (System is not driven by external driving force.) Why Study Thermodynamics ? - Thermodynamics predicts that the average macroscopic properties of a system in equilibrium are not independent from each other. Therefore, if we measure a subset of these properties, we can calculate the rest of them using thermodynamic relations. - Thermodynamics not only gives the exact description of the state of equilibrium but also provides an approximate description (to a very high degree of precision!) of relatively slow processes. -

Arxiv:0907.4184V1 [Gr-Qc] 23 Jul 2009 Keywords Anomalous Puzzle
Space Science Reviews manuscript No. (will be inserted by the editor) The Puzzle of the Flyby Anomaly Slava G. Turyshev · Viktor T. Toth Received: date / Accepted: date Abstract Close planetary flybys are frequently employed as a technique to place space- craft on extreme solar system trajectories that would otherwise require much larger booster vehicles or may not even be feasible when relying solely on chemical propulsion. The theo- retical description of the flybys, referred to as gravity assists, is well established. However, there seems to be a lack of understanding of the physical processes occurring during these dynamical events. Radio-metric tracking data received from a number of spacecraft that experienced an Earth gravity assist indicate the presence of an unexpected energy change that happened during the flyby and cannot be explained by the standard methods of mod- ern astrodynamics. This puzzling behavior of several spacecraft has become known as the flyby anomaly. We present the summary of the recent anomalous observations and discuss possible ways to resolve this puzzle. Keywords Flyby anomaly · gravitational experiments · spacecraft navigation. 1 Introduction Significant changes to a spacecraft’s trajectory require a substantial mass of propellant. In particular, placing a spacecraft on a highly elliptical or hyperbolic orbit, such as the orbit required for an encounter with another planet, requires the use of a large booster vehicle, substantially increasing mission costs. An alternative approach is to utilize a gravitational assist from an intermediate planet that can change the direction of the velocity vector. Al- arXiv:0907.4184v1 [gr-qc] 23 Jul 2009 though such an indirect trajectory can increase the duration of the cruise phase of a mission, the technique nevertheless allowed several interplanetary spacecraft to reach their target destinations economically (Anderson 1997; Van Allen 2003). -

Branches of Applied Physics Bardeen Feynmann 2016-03-05 What is Physics • Meaning of Physics (from Ancient Greek: φυσική (phusikḗ )) is knowledge of nature (from φύσις phúsis "nature"). • Physics is the natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves. • Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Over the last two millennia, physics was a part of natural philosophy along with chemistry, certain branches of mathematics, and biology, but during the scientific revolution in the 17th century, the natural sciences emerged as unique research programs in their own right. Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined. • New ideas in physics often explain the fundamental mechanisms of other sciences, while opening new avenues of research in areas such as mathematics and philosophy. 2016-03-05 What is Physics • Physics also makes significant contributions through advances in new technologies that arise from theoretical breakthroughs. • For example, advances in the understanding of electromagnetism or nuclear physics led directly to the development of new products that have dramatically transformed modern-day society, such as television, computers, domestic appliances, and nuclear weapons; advances in thermodynamics led to the development of industrialization, and advances in mechanics inspired the development of calculus.
