World Development

Scientific knowledge as well as experiment keeps on growing every day.  Experiments flourished in the seventeenth century. Previously, information about world development was obtained by connecting the roles of prominent epistemology. Experimentation is defined as a planned program for restoring hypotheses by providing empirical evidence to people. Science is a process of seeking the truth. Activities in finding the truth involves a series of scientific method including experiment. The development of physics history is divided into five periods. Period one is indicated by the absence of systematic and independent experiment. In period two, experimental methods had been accountable, and well accepted as a scientific issue. In period three, (investigations developed more rapidly when classical physics development began to be foundation of current famous quantum physics). Period four which is called The Old Quantum Mechanics is indicated by the invention of microscopic phenomena. Period five is well known by the emergence of new quantum mechanics theory.

Body Of Knowledge

Procedures for attaining scientific knowledge are known as scientific methods. These methods include formulating theories and testing them against observation or experiment. Ancient and medieval thinkers called any systematic body of knowledge a ‘science’, and their methods were aimed at knowledge in general. According to the most common model for scientific knowledge, formulated by Aristotle, induction yields universal propositions from which all knowledge in a field can be deduced. This model was refined by medieval and early modern thinkers, and further developed in the nineteenth century by Whewell and Mill. As Kuhn observed, idealized accounts of scientific method must be distinguished from descriptions of what scientists actually do. The methods of careful observation and experiment have been in use from antiquity, but became more widespread after the seventeenth century. Developments in instrument making, in mathematics and statistics, in terminology, and in communication technology have altered the methods and the results of science.

In crystal periodic structure prediction, a general equation is needed to determine the period vectors (cell edge vectors), especially when crystals are under arbitrary external stress. It has been derived in Newtonian dynamics years ago, which can be combined with quantum mechanics by further modeling. Here we derived such an equation in statistical physics, applicable to both classical physics and quantum physics by itself.

Modes Of Thought

The ArgumentScience consists in progress by innovation. Scientists, however, are committed to all kinds of traditions that persist or recur in society regardless of intellectual and institutional changes. Merton's thesis about the origins of the scientific revolution in seventeenth-century England offers a sociohistorical confirmation of this revisionist view: the emergence of a highly rational scientific method out of the religious-ethical sentiments of the English Puritans implies that scientific knowledge does indeed grow out of – and not really against – customary modes of thought.In tracing the intellectual origins of this view back to the religious controversy between Protestants and Catholics, the essay demonstrates that the essential conflict between them with regard to natural science stemmed from their antagonistic conceptions of tradition and its function in the production of genuine knowledge – of religious as well as of natural affairs. Whereas the Protestants believed only in those truths that are immediately revealed by God to each man through his reason, the Catholics adhered to truths that are related to men or “made” by them through culture and history.

Versus Complex

This study offers an epistemological discussion about the classic psychology and one of its present components, Gestalt therapy, using the trajectory of classical physics to quantum as a backdrop. There was a discussion through a review by addressing three points involving dichotomous (and still currently involved) a partial transition from classical physics to quantum physics (linearity versus nonlinearity; action and reaction versus complex; and classical mechanics versus quantum mechanics) and, illustratively, three points of discussion related to classical psychology as opposed to Gestalt therapy (causal versus existentialism; elementarism versus holism, and objectivity versus phenomenology). It was concluded that there are differences and similarities in the trajectories analyzed, as the paradoxical properties of its objects, the quantum and human consciousness, setting up contact points that enable a dialogue between both quantum physics and Gestalt-therapy.

Classical And Quantum Mechanics

AbstractLie algebras, in the form of algebras of observables, play an essential role in the formulation of classical and quantum mechanics. We discuss whether lie groups play a similar role in general relativity through the holonomy group. We also explore what interrelations these ideas provide between classical physics, relativity and quantum physics.

Subordinate Role

It now appears that quantum computers are poised to enter the world of computing and establish its dominance, especially, in the cloud. Turing machines (classical computers) tied to the laws of classical physics will not vanish from our lives but begin to play a subordinate role to quantum computers tied to the enigmatic laws of quantum physics that deal with such non-intuitive phenomena as superposition, entanglement, collapse of the wave function, and teleportation, all occurring in Hilbert space. The aim of this 3-part paper is to introduce the readers to a core set of quantum algorithms based on the postulates of quantum mechanics, and reveal the amazing power of quantum computing.

Orthodox quantum mechanics has another implicit postulate stating that temporal and spatial frequencies of the Planck–Einstein and de Broglie formulas can only be linked with the infinite, in time and space, harmonic plane waves of Fourier analysis. From this assumption, nonlocality either in space and time follows directly. This is what is called Fourier Ontology. In order to build nonlinear causal and local quantum physics, it is necessary to reject Fourier ontology and accept that in certain cases a finite wave may have a well defined frequency. Now the mathematical tool to describe this new approach is wavelet local analysis. This more general nonlinear local and causal quantum physics, in the limit of the linear approximation, contains formally orthodox quantum mechanics as a particular case.
