Essentials Of The Theory Of Abstraction - Lecture, Subhajit Kumar Ganguly

Subhajit Kumar Ganguly

In not favouring solutions or sets of solutions, the principle of zero-postulation drives away any unwanted incompleteness from the description of the world. It is the interactions between the possible exhaustive set of solutions that creates the impression pointedness or directiveness in the universe, leading to the formation of clusters, as discussed earlier. These interactions may be chaotic in nature, giving rise to attractor points where the directiveness inside any given system asymptotically seem to approach. It is this directiveness, in turn, inside a given system or in the universe as a whole, that is the cause of all known …

Holographic Renormalization Of Asymptotically Lifshitz Spacetimes, Robert Mcnees, Robert Mann

Robert A McNees IV

A variational formulation is given for a theory of gravity coupled to a massive vector in four dimensions, with Asymptotically Lifshitz boundary conditions on the fields. For theories with critical exponent z = 2 we obtain a well-defined variational principle by explicitly constructing two actions with local boundary counterterms. As part of our analysis we obtain solutions of these theories on a neighborhood of spatial infinity, study the asymptotic symmetries, and consider different definitions of the boundary stress tensor and associated charges. A constraint on the boundary data for the fields figures prominently in one of our formulations, and in …

Condensation States And Landscaping With The Theory Of Abstraction, Subhajit Kumar Ganguly

Subhajit Kumar Ganguly

The Abstraction theory is applied in landscaping. A collection of objects may be made to be vast or meager depending upon the scale of observations. This idea may be developed to unite the worlds of the great vastness of the universe and the minuteness of the sub-atomic realm. Keeping constant a scaling ratio for both worlds, these may actually be converted into two self-same representatives with respect to scaling. The Laws of Physical Transactions are made use of to study Bose-Einstein condensation. As the packing density of concerned constituents increase to a certain critical value, there may be evolution of …

Abstraction In Theory - Laws Of Physical Transactions, Subhajit Kumar Ganguly

Subhajit Kumar Ganguly

Considering transport or tendency of transport of physical entities from an initial to a final point,we come to a similar basis of understanding of various physical phenomena.The trajectory-behaviour of such transport represents the effect or field of influence.This way,we may explain cluster-formation in the universe,an expanding universe,etc.This may also lead to a similar basis for understanding the four non-contact forces of nature.Also,for different ranges of acceleration in the field formed in spacetime,we have different properties of matter interacting.This may explain the difference in ranges of the various forces.

Analyzing The Role Of Icts In The Tunisian And Egyptian Unrest From An Information Warfare Perspective, Brett Van Niekerk, Kiru Pillay, Manoj Maharaj

Manoj Maharaj

In January 2011, the Tunisian government stepped down after weeks of protests; this was followed by unrest and protests in Egypt against the Egyptian government, leading also to the resignation of its president. Demonstrations in both countries were facilitated in some part by the online social media and related information and communications technologies that impacted the flow of information. The manner in which the information and communication technologies were employed suggests that the uprisings were a form of social information warfare. To provide an alternative understanding of the role of technology and information in the events that led to the …

Star Formation In M33 (Herm33es), C. Kramer, M. Boquien, J. Braine, C. Buchbender, Daniela Calzetti, P. Gratier, B. Mookerjea, M. Relaño, S. Verley

Daniela Calzetti

Within the key project "Herschel M33 extended survey" (HerM33es), we are studying the physical and chemical processes driving star formation and galactic evolution in the nearby galaxy M33, combining the study of local conditions affecting individual star formation with properties only becoming apparent on global scales. Here, we present recent results obtained by the HerM33es team. Combining Spitzer and Herschel data ranging from 3.6um to 500um, along with HI, Halpha, and GALEX UV data, we have studied the dust at high spatial resolutions of 150pc, providing estimators of the total infrared (TIR) brightness and of the star formation rate. While …

Astrophysical Mechanisms For Pulsar Spindown, Eric Addison

Eric Addison

Pulsars are astrophysical sources of pulsed electromagnetic radiation. The pulses have a variety of shapes in the time-domain, and the pulse energy generally peaks in the radio spectrum. The accepted models theorize that pulsars are rapidly rotating neutron stars with strong dipolar magnetic fields. Current models predict that rotational kinetic energy is extracted from the pulsar in the form of electromagnetic and gravitational radiation, causing it to slowly lose rotational speed, or “spin down”. This spindown can be characterized by a single value n, known as the braking index. This report will review basic characteristics of pulsars, including short treatments …

Eric Addison

This short note will derive expressions for the instantaneous velocity of the components in a two-body elliptical Keplerian orbit.

Derivation Of Initial Velocities For A Two-Body Orbit In The Barycenter Frame, Eric Addison

Eric Addison

The readily available information for two body orbits generally refers to the one dimensional, reduced mass case. Information about initial conditions in the barycenter frame is not easily found. In order to derive the initial velocities required for a two-body orbit in the barycenter frame, the momentum of the reduced mass can be used.

A Scientific Rationale For Belief In God?, Philip E. Graves

PHILIP E GRAVES

This paper presents a concise scientific rationale for the existence of God. The works of Ray Kurzweil and the many other artificial intelligence researchers provide a backdrop to the central thesis. An entity (computers or humans, it not mattering which) will eventually approach all-knowing. How much time passes before this occurs is not important. All-knowing is likely to be all-powerful insofar as knowledge leads to power, as has been our experience. One would suspect that this would be inclusive of time travel. The methods by which knowledge grows require “seed” facts to begin working. The seed facts can easily be, …

Estimation Of Planetary Orbits Via Vectorial Relativity (Vtr), Jorge A. Franco

Jorge A Franco

The equation (approximate) for the Movement of Planets about a Massive Body, according to the theory VTR, is: d2u/(d2) + (1-6).u = , where u = 1/r and  are parameters. Applying the previous model we obtain the paths of several planets of the Solar System. In addition we obtain the precession for every planet using the formula given by the Vectorial Relativity and we compare it with the values of the precession given by the GTR (General Theory of the Relativity).

Gravitational Forces In Vectorial Relativity, Jorge A. Franco

Jorge A Franco

It is known that Kepler’s Laws can be derived from the Newton’s Law of Universal Gravitation. For doing this, mass is considered as an invariable parameter. Although this consideration works wonderfully to solve most of problems in astronomy calculations, as well as in all physics, when astral body’s speeds are so high and very precise measurements are required, the referred Kepler Laws do not cope enough what is expected. That’s why the General Theory of Relativity materialized. As it was indirectly pointed out by Einstein in 1905, Newton and Kepler Laws do not consider the relativistic variation of mass with …

Local Lorentz Transformations And Vectorial Relativity, Jorge A. Franco, Jose G. Quintero

Jorge A Franco

In previous work it was shown that instead of the known Lorentz Transformations (LT) the new obtained Vectorial Lorentz Transformations (VLT) were the transformations that truly respected the postulates of the Principle of Relativity and the consideration of the speed of light as a universal constant. In this review is presented the way how it is possible to obtain practical consequences of the VLT, and its applications to our real life.
