Evolutionary Aspects Of Energy Exchange In Open Systems (Physics Of Genetic Code And Dna)

de Andrei Moldavanov

~~125,88€~~ 113,29€ 10% IMEDIATO

DISPONIBILIDADE IMEDIATA

 This book focuses on a consistent approach to the possible origin of a genetic code (GC) and DNA based on the energy evolution of an open thermodynamic system. A phenomenon of energy evolution heavily relies on the infrastructure and regularities of stochastic energy exchange (SEE). Mathematically, an energy evolution takes the form of a randomized energy continuity equation. A concept of openness is achieved by using an unlimited number of energy links with the external environment. The new morphological features of SEE, as well as the role of time symmetry breaking in the creation of an infrastructure of energy exchange, are presented. Discovered SEE advances serve as an intuitive foundation for the origin of a genetic code and energy skeleton of DNA. As a result, the suggested approach leads to the formation of the numerical structure of GC with the magic numbers 3, 4, 20, and 64, with an intuitive extension to the 3-D mathematical image demonstrating the number of key features of real DNA.

DISPONIBILIDADE IMEDIATA

 In a way, nuclear energy has been serving man as long as he has existed. It has served all of life; it has flooded the earth for billions of years. The sun, you see, is a vast nuclear engine, and the warmth and light that the sun radiates is the product of nuclear energy. In order for man to learn to produce and control nuclear energy himself, however, three lines of investigation—atoms, electricity, and energy—had to develop and meet.

DISPONIBILIDADE IMEDIATA

 Hydrogen is one of the most important and versatile chemical elements on Earth. It has the unique distinction of being the lightest element occupying the first place in the periodic table. It is also the most abundant chemical substance in the whole universe, accounting for nearly 75% of all normal matter. Stars, like the sun, are mostly constituted of hydrogen in the plasma state. While this has been known to us from the early days of quantum mechanics, over the years, attempts have been made to study its behavior in various physical and chemical situations. In the last few decades, considerable progress has been made in investigating the nature of H-atoms in external environments (in both experimental and theoretical domain). This book contains 14 chapters by leading experts presenting some of the latest, exciting developments in the area. The chapters cover mostly theoretical, computational, and conceptual issues. Therefore, purely experimental works are not included, while results for various quantities are provided mainly to assess the quality of theory and feasibility of the method in question.

DISPONIBILIDADE IMEDIATA

 Density Functional Theory (DFT) is a cornerstone in computational quantum chemistry and condensed matter physics, offering a powerful framework for understanding and predicting the properties of atoms, molecules, and solids. It provides a computationally efficient alternative by focusing on the electron density rather than the many-body wave functions, significantly reducing the computational cost while retaining accuracy. DFT has been successfully applied to a wide variety of materials and systems encountered in chemistry, physics, materials science and beyond. It also plays a crucial role in tackling many-body problems in quantum mechanics, offering a versatile and efficient approach to understanding the electronic structure and properties of complex systems. Many-body problems involve interactions between multiple particles, making traditional wave function-based methods computationally demanding, and often impractical for large systems. This book provides a comprehensive and accessible exploration of the principle, methodologies, and practical applications of ab-initio computational techniques in the fields of material science. Starting from the basics of quantum mechanics, the book introduces readers to the theoretical foundations necessary for understanding ab-initio methods. It then systematically covers various computational approaches, including density functional theory (DFT), Hartree-Fock theory, and post-Hartree-Fock methods, offering insights into their underlying principles, and advantages. Additionally, the reader is introduced to the many important roles of DFT in revealing the electronic structure of materials, including band structures, energy gaps, Fermi surfaces, and NMR studies as well as in determining the effect of hydrostatic pressure on the optoelectronic and thermoelectric properties of materials.Moreover, it highlights DFT''s ability to accurately predict structural optimizations, phase transitions, and magnetic properties, offering invaluable insights into the behaviour of materials under diverse conditions. The editors believe that this book will serve as an indispensable resource for researchers, students, and practitioners who wish to leverage the predictive power of DFT in advancing scientific understanding and technological advances.

Atom - An Organism

de Bent Rolf Pettersen

~~108,65€~~ 97,79€ 10% IMEDIATO

DISPONIBILIDADE IMEDIATA

 Can atoms be looked upon in an organism metaphor? This book shows how groups of quarks and particles become atoms through energy growth and fusion. Atoms seem to have an advanced management system. They constantly perform several advanced tasks: the strong nuclear force, the attractive force, the repulsive force, and several other energy tasks. In addition, atoms seem to communicate with each other and are aware of their surroundings. They also constantly convert energy through Atomic Phase Displacement. These actions indicate an advanced management system. Atoms seem to act upon external information to preserve their structures. The properties of the attractive force are discussed, and a model combining atomic bindings and gravity is presented. This model works with quantum mechanics and astrophysics. Energy balance in atoms, dark energy, and dark matter are also included in the model - the ilefos model. The ilefos model suggests that atoms have a complex management system that can be looked upon in an organism metaphor.

Four-Dimensional Atomic Structure And Law

de Kunming Xu

304,75€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 A novel spacetime theory was developed to model the atomic structure and the law of electronic motion. Four space dimensions are four geometric elements in a sphere: two periphery points, two semicircular arcs, two hemispherical surfaces, and the inner and outer solid spheres that correspond to the electron octet in a neon shell. The dimension stairs within the atoms are the theoretical basis of electronic orbital quantization in quantum mechanics. The law of nature is dynamic calculus of spherical quantities that defines the motion of an electron from one dimension to another featuring general harmonic oscillation. The fresh mindset will subvert the traditional worldview. Two-dimensional spacetime is described with the instantiation of a helium shell in rigorous mathematics and extended to life phenomena. A husband and a wife are two dimensions of the family; and animals and plants are two kingdoms of the advanced lives. The interplay and transformation between both dimensions are the eternal theme of nature and can be abstracted as a mathematical rope. A DNA molecule, composed of space and time strands, is a stepwise LC oscillatory circuitry or a rope; so is a human lineage with both sexes. Under the four-dimensional space framework, we formulate the wave functions of all electrons within inert atoms. The electronic structure of a chiral carbon conforms to the yin and yang theory and the five element theory in traditional Chinese medicine. It constitutes a physical instance of spherical quantity solutions to three-dimensional Schrödinger’s equation. Spherical quantities in dynamic calculus complement physical quantities with linear algebra, comply with the Pythagorean theorem and Maxwell’s equations, and characterize the rhythms of entities essentially.

Wave Equation: An Overview

125,88€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 This book presents a quantum gravity theory based on unification of all quantum fields into a single field. The authors assess whether the equations of motion or the conservation equations are more fundamental. The application of this resolution to the Transmission Line Matrix modeling method for numerically solving the wave equation is also addressed. Flux density is proportional to the density of momentum. As such, the general procedure is described wherein this concept is applied to other Hermitian operators. An alternative metric is presented in this compilation which satisfies Einstein’s field equations. This metric does not depend on weak field approximation, however it replaces Schwarzschild metric under certain conditions and provides an elegant solution for the rotation curves of galaxies as well as the energy levels of hydrogen atom. An optical wave equation for scattered light in materials with macroscopic spatial inhomegeneites is presented and analysed. The equation is applicable to variety of linear and nonlinear optical interactions in media with intrinsic, induced or engineered inhomegeneites. Lastly, the authors explore a black hole solution to the Jackiw-Teitelboim field equations for two-dimensional gravity. It turns out that the wave frequency is also connected to a suitable black hole metric, dilaton field, and cosmological constant.

Origin Of Gravity From The First Principles

304,75€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 This book presents a collection of chapters in which researchers who have worked in the field of gravity for years reveal their visions of the origin of gravity. Some approaches are based on field equations and ideas of general relativity, but others suggest their own procedures. Among the visions we see the further development of principles of general relativity, which unify gravity with fluctuations of matter or a background of super-strong interacting gravitons, as well as visions that ignore complicated interactions of gravity with other fields altogether. There is also a new approach in which space-particle dualism is presented. In addition, there is the approach that suggests starting directly with the smallest granularity of space, defined by the Planck scale. These lines of study involve constructions and methods emerging from quantum mechanical formalism and even suggestions for new courses of action, such as subquantum kinetics and submicroscopic mechanics. These approaches all try to explain the concepts of particle, mass, and their interactions. These are new trends both in the theory of gravitation and in the theory of elementary particles, and hence fundamental physics in general.

World Of Circulating Light Where Ball Lightnings Live

de Vladimir Torchigin

212,00€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 The book describes a completely new world, the existence of which no one had even suspected before. Therefore, this world could not be studied either theoretically or experimentally. The study of the nature of ball lightning made it possible to discover this world. Pyotr Kapitsa, a Russian scientist, Nobel Prize winner, studying the phenomenon of ball lightning, was forced to admit at the end of his life that this bright nut was too strong for his teeth. At the same time, he suggested that ball lightning is a phenomenon from another world unknown to him. Indeed, he was partly right. He was wrong that ball lightning was related to plasma, but he was right that ball lightning belonged to another world unknown to him. The book describes the features of this world and the properties of its inhabitants. The most known among them is ball lightning. This world we called the world of circulating light. This book is not science fiction. The book is based on over eight dozen articles published since 2003 in leading international physics and optics journals. Although scientists have not been able to unravel the nature of ball lightning for many centuries, it turned out that the explanation is so simple that it is accessible to schoolchildren. Such an explanation can be given without a single formula, recalling only the well-known physical laws from the school curriculum.

Quantum Field Theory And Applications

212,00€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 Quantum field theory (QFT) is a theoretical framework that combines classical field theory, special relativity and quantum mechanics, and represents the forefront of theoretical physics. The four chapters of this book include new research on quantum field theory and present different perspectives on the subject. Chapter One applies the notion of clothing particles in QFT to the theory of nuclear forces and quantum electrodynamics. Chapter Two is based on results from black hole thermodynamics at all energy scales and demonstrates that there is a natural ultraviolet applicable boundary distant from the Planck scales in QFT. Chapter Three presents a version of quantum field theory based on discrete energy-momentum and illustrates this theory using examples of fermion and boson fields. Lastly, Chapter Four discusses in detail whether or not perturbative expansion series in quantum electrodynamics are convergent and points out that the disagreement between the experimental value of the muon g-2 and the theoretical one predicted in the standard model might be due either to the larger hadronic vacuum polarization contributions or to an unexpectedly large sum of the perturbative expansion series.
