Available in PDF, EPUB and Kindle. Book excerpt: Information about the reality outside flow via our sense organs into the body, and the brain forms a picture of reality. It is argued that the symbols in the picture have in general no similarity with the objects in the outside world, and many facts support such a view. This conception is discussed in connection with quantum reality. In particular, the role of space and time within quantum theory is also investigated from the historical point of view, highlighting the original ideas. New aspects are covered in connection with the particle concept, particle-wave dualism, locality, the time operator, the superposition principle, and the role of the observer.

Download or read book The Visible and the Invisible written by Wolfram Schommers and published by World Scientific. This book was released on 1998-04-04 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: How do we get an idea from the physical world? There is basically only one possibility, namely the dialogue with nature, i.e. we create a theoretical conception of the world by thinking, and then we check this conception with the help of measuring instruments. In this connection the following question arises: Does there exist for each element of the theory an element-specific deflection at the measuring instrument? In other words, has each element of the theory a counterpart in the actual reality? If not, then the theory contains metaphysical elements, i.e. elements which have no counterpart in reality. In this book it is argued that there are obviously no theoretical conceptions of the world which are free of metaphysical elements. This is not only valid in connection with matter but also for the conceptions of space and time. The consequences in connection with modern conceptions of the world are outlined.

Download or read book Quantum Capacitance In Quantized Transistors written by Kamakhya Prasad Ghatak and published by World Scientific. This book was released on 2024-02-06 with total page 886 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, there has been considerable interest in studying the quantum capacitance (QC) in 2D quantum MOSFETs (QMOSFET) and 1D Nano Wire FET (NWFET) devices of various technologically important materials which find extensive applications in many directions in low dimensional electronics. The 2D and 1D electron statistics in inversion layers of MOSFETs can rather easily be varied by changing the gate voltage which, in turn, brings a change of the surface electric field, the QC depends on the gate-voltage. This first-of-its-kind book deals solely with the QC in 2D MOSFETs of non-linear optical, ternary, quaternary, III-V compounds, II-VI, IV-VI, stressed Kane type, Ge, GaP, Bismuth telluride, Gallium Antimonide and their 1D NWFETs counter parts. The influence of quantizing magnetic field, crossed electric and magnetic fields, parallel magnetic field, have also been considered on the QC of the said devices of the aforementioned materials. The influences of strong light waves and ultra-strong electric field present in nano-devices have also been considered. The accumulation layers of the quantum effect devices of the said materials have also been discussed in detail by formulating the respective dispersion relations of the heavily doped compounds. The QC in 1D MOSFET of the said materials have also been investigated in this context on the basis of newly formulated electron energy spectra in all the cases. The QC in quantum well transistors and magneto quantum well transistors together with CNTFETs have been formulated and discussed in detail along with I-V equations of ballistic QWFETs and NWFETs together with their heavily doped counter parts under different external physical conditions. In this context, experimental determinations are suggested of the Einstein relation for the Diffusivity-Mobility ratio, the Debye screening length, Elastic Constants and the content of this book finds twenty-two different applications in the arena of nanoscience and nanotechnology.This book contains hundred open research problems which form the integral part of the text and are useful for both PhD aspirants and researchers.

Download or read book The Far Horizons of Time written by H. Chris Ransford and published by Walter de Gruyter GmbH & Co KG. This book was released on 2015-04-24 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is Time? Assuming no prior specialized knowledge by the reader, the book raises specific, hitherto overlooked questions about how time works, such as how and why anyone can be made to be, at the very same instant, simultaneous with events that are actually days apart. It examines abiding issues in the physics of time or at its periphery which still elude a full explanation ― such as delayed choice experiments, the brain's perception of time during saccadic masking, and more ― and suggests that these phenomena can only exist because they ultimately obey applicable mathematics, thereby agreeing with a modern view that the universe and everything within it, including the mind, are ultimately mathematical structures. It delves into how a number of conundrums, such as the weak Anthropic Principle, could be resolved, and how such resolutions could be tested experimentally. All its various threads converge towards a same new vision of the ultimate essence of time, seen as a side effect from a deeper reality.

Download or read book Quantum Reality and Theory of nya written by Siddheshwar Rameshwar Bhatt and published by Springer. This book was released on 2019-03-30 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with expounding the nature of Reality as it is understood in contemporary times in Quantum Physics. It also explains the classical Indian theory of Śūnya in its diverse facets. Thereafter it undertakes comparison between the two which is an area of great topical interest. It is a cross-disciplinary study by erudite Indian and western scholars between traditional Indian knowledge system and contemporary researches in Physical sciences. It points out how the theory of ‘Śūnyatā has many seminal ideas and theories in common with contemporary Quantum Physics. The learned authors have tried to dissolve the “mysteries” of Quantum Physics and resolved its “weird paradoxes” with the help of theory of Śūnyatā. The issue of non-separability or entanglement has been approached with the help of the Buddhist theory of Pratītyasamutpāda. The paradoxical situation of “wave-particle duality” has been explained with the help of Upaniṣadic theory of complementarity of the two opposites. The measurement problem represented by “Schrodinger’s cat” has been dealt with by resorting to two forms of the calculation of probabilities. Some writers have argued for Śūnyatā-like non-essentialist position to understand quantum reality. To make sense of quantum theory some papers provide a happy symbiosis of technical understanding and personal meditative experience by drawing multifarious parallels. This book will be of interest to philosophically inclined physicists and philosophers with interest in quantum mechanics.

Book excerpt: The book of Erwin Schrödinger about life evokes a variety of basic questions concerning the understanding of life in terms of modern physics rather than biochemistry. Problems of organization and regulation of biological systems cannot be understood by revealing only the chemical processes of the living state. A group of reputable physicists — among them the followers of Heisenberg and Fröhlich — and biologists came to this same conclusion through several workshops on this topic. This book contains their contributions, written from different viewpoints of theoretical physics and modern biology. These articles are valuable not only for understanding life, but also for creating new and non-invasive diagnostic and therapeutic tools in medicine; they also contribute importantly to a deeper understanding of evolutionary processes, including the development of consciousness.

Download or read book Origin Of Natural Order The An Axiomatic Theory Of Biology written by Zhao Qinyi and published by World Scientific. This book was released on 2017-09-22 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: All sorts of biological activities are processed thermodynamically, and at the utmost fundamental level, the laws of biology must be thermodynamics. However, the current laws of thermodynamics are unable to give reasonable explanation of biological processes. In order to do so, irreversible thermodynamics has been theorized to describe the basic mechanism for the origin of natural order or the development of things (related to developmental biology). The scientific definition of the system theory concept has been obtained and the properties of a biological system can be analyzed by applying principles of it. Irreversible thermodynamics and system theory act as the theoretical foundation for theoretical biology. By applying principles of irreversible thermodynamics and system theory, the axiomatic theory of biology has been developed.

This book was released on 2021-12-17 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the development of the scanning tunneling microscope, nanoscience became an important discipline. Single atoms could be manipulated in a controlled manner, and it became possible to change matter at its 'ultimate' level; it is the level on which the properties of matter emerge. This possibility enables to construct and to produce devices, materials, etc. with very small sizes and completely new properties. That opens up new perspectives for technology and is in particular relevant in connection with nano-engineering.Nanosystems are unimaginably small and very fast. No doubt, this is an important characteristic. But there is another feature, possibly more relevant, in connection with nanoscience and nanotechnology. The essential point here is that we work at the 'ultimate level'. This is the smallest level at which the properties of our world emerge, at which functional matter can exist. In particular, at this level biological individuality comes into existence. This situation can be expressed in absolute terms: This is not only the strongest material ever made, this is the strongest material it will ever be possible to make (D Ratner and M Ratner, Nanotechnology and Homeland Security). This is a very general statement. All aspects of matter are concerned here. Through the variation of the composition various forms of matter emerge with different items.Nanosystems are usually small, but they offer nevertheless the possibility to vary the structure of atomic (molecular) ensembles, creating a diversity of new material-specific properties. A large variety of experimental possibilities come into play and flexible theoretical tools are needed at the basic level. This is reflected in the different disciplines: In nanoscience and nanotechnology we have various directions: Materials science, functional nanomaterials, nanoparticles, food chemistry, medicine with brain research, quantum and molecular computing, bioinformatics, magnetic nanostructures, nano-optics, nano-electronics, etc.The properties of matter, which are involved within these nanodisciplines, are ultimate in character, i.e., their characteristic properties come into existence at this level. The book is organized in this respect.
