Since the discovery of strongly radioactive substances, research on radioactivity has been greatly developed. I propose in this article to give an account of the actual state of our knowledge relative to this subject, laying particular stress on the most recent work.(Pierre Curie - 1904)

Come sarebbe un libro con una struttura fisica e concettuale che non potrebbe assumere? In cui i paragrafi, e forse anche le parole e le lettere, non fossero disposti con ordine ma distribuiti casualmente? Come sarebbe descritta la proposta dellabbandono di ogni teoria senza farne una teoria, una proposta o una descrizione? E come sarebbe farlo con una lingua che non puo essere altro che convenzionale e con parole che non hanno un significato se non quello arbitrariamente attribuito loro? Come sarebbe farlo lamentando la mancanza di esplicitazione del meccanismo che regola lassegnazione e luso dei nomi, sottolineando che la logica puo solo essere relativa e che vari tipi di falsita sono piu adatti di un solo tipo di verita per essere usati per interpretare cio che viene comunicato? Come potrebbero essere date risposte a queste domande se anche la conoscenza fosse messa in dubbio e il domandare stesso questionato? Apparizione del Dissolventismo

The Italian physicist Ettore Majorana mysteriously disappeared in 1938. Majorana was part of the famous Via Panisperna group directed by Enrico Fermi. In those years the model of heavy atom (that is, with many electrons) was proposed, and Fermi elaborated a model based on Statistical Quantum Mechanics known as the Thomas-Fermi model (as established in the same period by Llewellyn Thomas). This model was governed by a nonlinear second-order differential equation. Numerical integration was extremely complicated. Fermi and his group had been working on it for a week. Ettore Majorana only needed one nights work not only to integrate the equation, but to develop a sophisticated algorithm for the solution of an entire class of differential equations. In the ebook that we offer today we present our solution obtained with the aid of the Mathematica software.Subjects:Genesis of the Thomas - Fermi equationHistorical noteA particular integral of the Thomas-Fermi equationA boundary problemA boundary problemComplete solutionMarcello Colozzo, a graduate in Physics, has been involved in online teaching of Mathematics and Physics since 2008 through the Extra Byte website where "simulations" are performed in the Mathematica computing environment.

Max Planck was unintentionally a revolutionary. In fact, in dealing with a thorny problem that afflicted physics at the end of the 19th century (the black body emission spectrum) he used a mathematical trick to ensure the convergence of what mathematicians call the "integral generalized". And not only that, his solution was in perfect agreement with the experimental data. "Unfortunately" (for Planck who adhered to the paradigm of classical physics), what he had used was much more than a simple artifice: Nature was revealing something very interesting to us.Ebook Topics:Experimental featuresStefan-Boltzmann law.Wiens law.Displacement lawTheoretical settingThe Rayleigh-Jeans radiation formulaMarcello Colozzo, a graduate in Physics, has been involved in online teaching of Mathematics and Physics since 2008 through the Extra Byte website where "simulations" are performed in the Mathematica computing environment.

The third volume of IISSIIDIOLOGY Fundamentals allows readers to go deeper into yet completely unexplored by us structures that provide functioning of human Self-Consciousness and its interconnections with Self-Consciousnesses Forms focused by it. First two volumes of IISSIIDIOLOGY Fundamentals thoroughly describe the deep Nature of Causes and Mechanisms of Creative Activity of everything manifested in multidimensional and different-Qualitative Macrocosmos, including also qualitative Basis of Focus Dynamics of Form-Creators of Universal Structures. The third volume in its turn focuses on the detailed description of basic Principles of exhiberation of Human and other Self-Consciousnesses Forms in all the diversity of different-dimensional diapasons of the Tertiary Illusion.To allow the reader to fully comprehend the essence of the notion Self-Consciousness Form, the author describes realization functions of these structures at the example of subjective formation as a result of life creativity of every personality of so called personalistic Worlds, which goes far beyond existing scientific notions about the surrounding reality and peculiarities of interaction between Forms structuring it, whether it is a human, a planet, or an elementary particle. Furthermore, he describes different-dimensional variety of Forms of lluuvvumic Direction of development and characteristics of focal realization of Humankind Collective Cosmic Intelligence as a unified the LLUU-VVU-Entity.The third volume ends with a detailed description of multi-level manifestation of Plasmic Forces Diapasons of our Universe, which are described from a position of their subjective interpretation through the specific peculiarities of human Perception systems. Endless inner transformations of Universal Illusion, as mechanisms of evolutional growth of the Cosmic Human on its Way to its Universal Future, lets inquisitive readers to form in their Self-Consciousness own highly intuitive conceptions about endless varieties of all possible variants of development, where goes the process of eternal multidimensional Existence of every human personality.

In this book, Oris continues to give full answers to inmost and fundamental questions of cosmic and human existence: about Earth and universal destinies, the nature of life and death, Soul and God, good and evil, about our relations with one another, the nature of Space-Time and how the entire visible and invisible-to-us reality is formed.The Universal Knowledge given by Oris offers the fundamentals of a new and unique world view for all of us. It allows us to penetrate the mystery of eternal existence to an extent inaccessible before, reasonably and substantially solving the problems therein, offering convincing answers which are not available in any religious world view, philosophical movement or scientific theory. Oriss Information expands the limits of human experience and perception literally to infinity!

In the first Chapter of Volume, Oris describes in detail functioning of Formo-Creators of the brain, how the memory is accessed, how biological structures of the brain are associated with energy-informational structures of Self-Consciousness, how various Self-Consciousness Levels are differentiated and reprojected at the moment of so-called Death. This Chapter also describes functioning of the intestinal brain, how it becomes possible to cure at a distance (the technique of ethereal projection), gives the meaning of the esoteric term the Astral Plane from the point of view of Iissiidiology.The second Chapter tells us that biological Forms can exist in different Continuums and explains the interrelationship between our lifespan and quality of active Levels of our Self-Consciousness. It also provides information on the following subjects: it is possible to live ones Life many times in higher-quality scenarios, cycles of changing male and female manifestations within the structure of a multidimensional human Form, physical principles of organization of higher-frequency levels of the Universal Reality with a detailed description of the nature of boson and fermion fields, and types of particles that are carriers of such interaction.

The Conscious Path to the Human Worlds of personal Immortality - this is the name of the new volume from ORIS book cycle Immortality is accessible to everyone. At first glance, this may seem like an invitation to a philosophical contemplation. But by appealing to his devoted readers, the author hopes for the consideration and perception of this issue in a broader or, if you like, deeper understanding. Philosophical concepts offer to us only sensory-contemplative, mostly associative images regarding a particular issue. The author, however, presents in this work, as a logical continuation of previous volumes, a detailed consideration of the practical prospects for the development of a personality into a true Human, who explores his own spirituality.In addition to the mechanisms of working with own Self-Consciousness, which will lead people as Humans to personal conscious Immortality, ORIS describes the Worlds of our Future, the prospects for the manifestation of the coming times. And in order for everyone to develop an understanding of their own Path, a comprehension of the choice of their spiritual development, the author not only describes bright prospects, but also specifies in detail the obstacles that each of us may face and, by not noticing or not determining the nature of which, to unconsciously, under the influence of particular reasons, deviate from the development in the Human direction.With the help of this book, you will be able to determine the qualities that are truly inherent in people, and you can finally figure out how to form in yourself these qualities that are truly Human - with a capital letter. Having experienced what a highly sensual Intellect is, you will then understand why only with the help of highly intellectual Altruism you can find the Path to the cherished Goal of your spiritual future!

This new volume of the series Iissiidiology Fundamentals is a reasonable consequence of consideration of biological mixtum NUU-VVU-Form-Types that was started in the previous volume. For our deeper understanding, it draws our attention even more at iissiidiological approach to the matters, which are related discretely by contemporary scientific community to philosophic anthropology in general and to behavior theories of personality in particular.At more objective, transcendent, gabitual (primordial, objectively deep) discussion, it becomes clear that the given material leads a reader maximally to objectivization of own conceptions about relations among personalized, unconscious, and subconscious levels of Self-Consciousness at the background of developing invizusal (imperceptible by our sensor systems and measuring devices) mechanisms of anatomy and brain neurophysiology, accompanied by dominant dynamics of the first IISSIIDI-Centers pair.

Thoughtful study of this material allows the reader to get a more objective idea of the material basis of idealism by developing, in particular, quantum theory of Consciousness on the example of "microtubule concept". The reader will also learn about chakram determinacy of Focus Dynamics of all Self-consciousness Forms, will get an understanding of primary connections of thought formation, will get unique information about informational-energy conditionality of ontogenesis and embryogenesis, pathogenesis in general and hereditary diseases in particular, and finally will discover the universal etiological model of one of the most complex human feelings - the feeling of love.

In the beginning of the volume, the author recalls generation principles and mechanisms of the human subjective Realities, explains interconnections between the Tertiary and the Secondary Illusions Form-Creators, while describing thoroughly Fields-Consciousnesses structure, defines birvulyarity and its Qualitativeness types conception. The main part of the volume is devoted to description of the Reasons and principles of the Universe Cosmic Entity Focus Dynamics, various energo-informational structures of Its Self-Consciousness, and also to disclosure of SFUURMM-Forms human-type realization process and Form-Creators Focus Dynamics amplificational aggradation process.This volume concludes with summarizing, integration of everything described with Information about Universal Cosmic Laws and Their Principles providing fundamental basis for generation of all Self-Consciousnesses Forms in Macrocosmos Tertiary, the Secondary, and the Primary Illusions.

Si sente parlare sempre piu spesso di cambiamenti climatici, sostenibilita ambientale, carbon neutrality, compensazione delle emissioni di CO2, greenwashing, crediti di carbonio e finanza climatica.Ma cosa significano davvero questi concetti e perche e importante che siano conosciuti e compresi anche dai non addetti ai lavori?LEra del Fuoco e il primo libro italiano che affronta con un linguaggio non tecnico tutti questi temi di grande attualita, e lo fa accompagnando il lettore in un viaggio in Madagascar, per mostrargli gli effetti della crisi climatica in questo Paese, le soluzioni che si possono realizzare per creare un impatto positivo per le comunita locali e le ricadute che queste soluzioni possono generare per tutto il pianeta.LEra del Fuoco e anche un libro che parla di Aid4Mada, la ONG di cui lautore fa parte e che dal 2015 sta portando un aiuto concreto alle popolazioni piu svantaggiate del Sud del Madagascar. Dopo La Storia dellAcqua e La Fine della Terra, in questo terzo capitolo della storia lautore torna in Madagascar, per comprendere cosa e cambiato dopo la pandemia da Covid e come Aid4Mada ha aiutato le comunita locali a fronteggiarla.Un libro che si rivolge quindi a chi vuole conoscere gli strumenti a disposizione per contrastare i cambiamenti climatici, a chi vuole scoprire la realta di uno dei Paesi piu belli e allo stesso tempo piu poveri del mondo, a chi vuole capire meglio quale ruolo puo giocare per contrastare la crisi climatica, ambientale e sociale di oggi, sia in Madagascar che nel resto del mondo.
