This book was released on 2020-02-04 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'atomo è sempre stato al centro dell'attenzione delle scienze che studiano la natura. Inizialmente considerato come particella fondamentale e indivisibile della materia, da cui il nome, è stato inquadrato dalla fisica, grazie alle sue teorie, che ne ha compreso i costituenti e le proprietà. La nascita e lo sviluppo della fisica quantistica, che ha rivoluzionato il modo di pensare di molti, scienziati e non, ha finalmente permesso una descrizione finale ed elegante della particella che forma le molecole di cui è fatta la materia: l'atomo. Gli atomi sono i mattoni della materia, mentre le particelle elementari sono i costituenti ultimi delle particelle e, quindi, anche degli atomi. In aggiunta, ciascuna interazione fondamentale possiede una particella elementare che ha le funzioni di mediatrice di tale forza. Un esempio è il fotone, mediatore dell'interazione elettromagnetica. Si parlerà delle particelle elementari della fisica, raggruppate nel cosiddetto Modello Standard, come ad esempio i quark che compongono protoni e neutroni che a loro volta formano il nucleo degli atomi. La natura intera funziona grazie alla collaborazione delle quattro forze fondamentali. La gravità e l'interazione elettromagnetica sono le più note e spesso sono sufficienti le loro formulazioni classiche, non quantistiche per trattare i fenomeni che accadono nella vita quotidiana. Tuttavia una teoria fisica, per essere tale, deve tenere conto della teoria quantistica e della relatività ristretta di Einstein e di tutte le loro conseguenze. Quali sono dunque, nel dettaglio e se esistono, le teorie quantistiche e relativistiche che regolano le quattro forze fondamentali della natura? Autore: dott. Alessio Mangoni, fisico teorico.

Download or read book The Unconscious as Infinite Sets written by Ignacio Matte Blanco and published by Routledge. This book was released on 2018-03-29 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: A systematic effort to rethink Freud's theory of the unconscious, aiming to separate out the different forms of unconsciousness. The logico-mathematical treatment of the subject is made easy because every concept used is simple and simply explained from first principles. Each renewed explanation of the facts brings the emergence of new knowledge from old material of truly great importance to the clinician and the theorist alike. A highly original book that ought to be read by everyone interested in psychiatry or in Freudian psychology.
Download or read book Atoms in the Family written by Laura Fermi and published by University of Chicago Press. This book was released on 2014-10-24 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this absorbing account of life with the great atomic scientist Enrico Fermi, Laura Fermi tells the story of their emigration to the United States in the 1930s—part of the widespread movement of scientists from Europe to the New World that was so important to the development of the first atomic bomb. Combining intellectual biography and social history, Laura Fermi traces her husband's career from his childhood, when he taught himself physics, through his rise in the Italian university system concurrent with the rise of fascism, to his receipt of the Nobel Prize, which offered a perfect opportunity to flee the country without arousing official suspicion, and his odyssey to the United States.
Download or read book Facets of Systems Science written by George J. Klir and published by Springer Science & Business Media. This book was released on 2013-11-21 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has a rather strange history. It began in Spring 1989, thirteen years after our Systems Science Department at SUNY -Binghamton was established, when I was asked by a group of students in our doctoral program to have a meeting with them. The spokesman of the group, Cliff Joslyn, opened our meeting by stating its purpose. I can closely paraphrase what he said: "We called this meeting to discuss with you, as Chairman of the Department, a fundamental problem with our systems science curriculum. In general, we consider it a good curriculum: we learn a lot of concepts, principles, and methodological tools, mathematical, computational, heuristic, which are fundamental to understanding and dealing with systems. And, yet, we learn virtually nothing about systems science itself. What is systems science? What are its historical roots? What are its aims? Where does it stand and where is it likely to go? These are pressing questions to us. After all, aren't we supposed to carry the systems science flag after we graduate from this program? We feel that a broad introductory course to systems science is urgently needed in the curriculum. Do you agree with this assessment?" The answer was obvious and, yet, not easy to give: "I agree, of course, but I do not see how the situation could be alleviated in the foreseeable future.
Download or read book Majorana Case The Letters Documents Testimonies written by Erasmo Recami and published by World Scientific. This book was released on 2019-12-19 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'The Majorana Case is beautifully written, with a pleasant style, and concatenates a great deal of material. A text that could only be written by those who know the life and work of Ettore Majorana very well, as Prof Recami. The book traces the extraordinary life of Ettore Majorana — through his letters, documents and several testimonies from his friends and family members. What makes it more fascinating is that the author presented it also as a detective-story, by exploring his mysterious disappearance at young age. The personal testimonies also give to the book a welcome surplus. The Majorana Case, therefore, is both a pleasant biography and a mystery book.'Contemporary PhysicsEttore Majorana was born in the Sicilian city of Catania. He joined Enrico Fermi's 'Via Panisperna boys' at an early age and was part of the team who first discovered the slow neutrons (the research that would lead to the nuclear reactor and eventually, the atomic bomb). Enrico Fermi considered him one of brightest scientists, comparable to Galileo and Newton.On March 25, 1938, Ettore Majorana mysteriously disappeared at 31. When the author moved to the University of Catania, Sicily, from Milan University back in 1968, he soon discovered important documents pertaining to Majorana's life and works. Together with his own investigative materials and full cooperation from Majorana's family members, he published a book on his disappearance in Italian (after having helped the famous Italian writer, Leonardo Sciascia, to write down his known Essay, by supplying him with copy of some of the discovered documents). Recami's book was entitled Il Caso Majorana — Epistolario, Documenti, Testimonianze and when it first appeared in Italy, it drew interest from all the major newspapers, publications and TVs & broadcast media.Even after his disappearance, Ettore Majorana's name appeared in many areas of frontier physics research, ranging from elementary particle physics to applied condensed matter, to mathematical physics, and more. His long lasting contributions is a testimony of his brilliance and farsightedness and has continued to draw interest from scientists not only in Italy, but from all over world until today.An English version of the original is very appropriate at this juncture, when more and more scholars in the world are getting convinced that he was really a genius 'like Galileo and Newton'. This book traces the extraordinary life of Ettore Majorana — through his letters, documents and testimonies from his friends and family members. What makes this book more fascinating (as a detective-story too) is his mysterious disappearance at young age. This book, therefore, is both a biography and a mystery book.

Download or read book The Rediscovery of the Mind written by John R. Searle and published by MIT Press. This book was released on 1992-07-08 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this major new work, John Searle launches a formidable attack on current orthodoxies in the philosophy of mind. More than anything else, he argues, it is the neglect of consciousness that results in so much barrenness and sterility in psychology, the philosophy of mind, and cognitive science: there can be no study of mind that leaves out consciousness. What is going on in the brain is neurophysiological processes and consciousness and nothing more—no rule following, no mental information processing or mental models, no language of thought, and no universal grammar. Mental events are themselves features of the brain, "like liquidity is a feature of water." Beginning with a spirited discussion of what's wrong with the philosophy of mind, Searle characterizes and refutes the philosophical tradition of materialism. But he does not embrace dualism. All these "isms" are mistaken, he insists. Once you start counting types of substance you are on the wrong track, whether you stop at one or two. In four chapters that constitute the heart of his argument, Searle elaborates a theory of consciousness and its relation to our overall scientific world view and to unconscious mental phenomena. He concludes with a criticism of cognitive science and a proposal for an approach to studying the mind that emphasizes the centrality of consciousness to any account of mental functioning. In his characteristically direct style, punctuated with persuasive examples, Searle identifies the very terminology of the field as the main source of truth. He observes that it is a mistake to suppose that the ontology of the mental is objective and to suppose that the methodology of a science of the mind must concern itself only with objectively observable behavior; that it is also a mistake to suppose that we know of the existence of mental phenomena in others only by observing their behavior; that behavior or causal relations to behavior are not essential to the existence of mental phenomena; and that it is inconsistent with what we know about the universe and our place in it to suppose that everything is knowable by us.

Download or read book The Law of Causality and Its Limits written by Philipp Frank and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Law of Causality and its Limits was the principal philosophical work of the physicist turned philosopher, Philipp Frank. Born in Vienna on March 20, 1884, Frank died in Cambridge, Massachusetts on July 21, 1966. He received his doctorate in 1907 at the University of Vienna in theoretical physics, having studied under Ludwig Boltzmann; his sub sequent research in physics and mathematics was represented by more than 60 scientific papers. Moreover his great success as teacher and expositor was recognized throughout the scientific world with publication of his collaborative Die Differentialgleichungen der Mechanik und Physik, with Richard von Mises, in 1925-27. Frank was responsible for the second volume, on physics, and especially noted for his authoritative article on classical Hamiltonian mechanics and optics. Among his earliest papers were those, beginning in 1908, devoted to special relativity, which together with general relativity and physical cosmology occupied him throughout his life. Already in 1907, Frank published his seminal paper 'Kausalgesetz und Erfahrung' ('Experience and the Law of Causality'), much later collected with a splendid selection of his essays on philosophy of science, in English (1941c and 1949g, in our Bibliography). Joining the first 'Vienna Circle' in the first decade of the 20th century, with Hans Hahn, mathematician, and Otto Neurath, sociologist and economist, and deeply influenced by studies of Ernst Mach's critical conceptual histories of science and by the striking challenge of Poincare and Duhem, Frank continued his epistemological investigations.
Download or read book La Fisica Reale Teoria dei Fotoni e degli Elettroni written by Antonino Ciancitto and published by Carmelita Ciancitto. This book was released on with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Il volume è disponibile in formato digitale su Google Play e Google Libri. Per la versione cartacea presente su Amazon è utilizzabile il bonus cultura o il bonus carta del docente. La Fisica Reale propone una interpretazione della fisica “meccanicistica” newtoniana su nuove e migliori basi. In questo contesto l’opera è un’esposizione originale e comprensibile a chiunque, che chiarifica in modo magistrale le basi della fisica moderna imperniata su di una oscura ed indescrivibile onda-corpuscolo. All’intelletto fisico che ricerca la chiave del fenomeno “luce” si frappongono due immagini che si contraddicono tra di loro, onde e corpuscoli. Anche l’elettrone, granello di materia, che si presenta sotto i due aspetti “vibratorio” e “corpuscolare” viene interpretato secondo questa duplice visione. Ma la materia, come si potrà constatare meglio leggendo, si estrinseca in realtà secondo meccanismi ad “orologeria”, che solo in prima approssimazione possono dare questa falsa doppia impressione. Ponendo al giusto posto i mattoni fondamentali, con cui risulta formata, si possono svelare le intime relazioni che corrono tra i fenomeni atomici. Da questa nuova visione della materia deriva un “vuoto” privo di attività e di attributi ed una rappresentazione della Natura di tipo a “orologio”. Sviscerando il concetto di materia si raggiunge anche la convinzione della esistenza di componenti primigeni eternamente in moto e dotati di carica elettrica intrinseca e spin come quelli investigati dal pensiero moderno. Il testo spiega anche il come ed il perché delle principali caratteristiche dell’elettrone, quali la massa, lo spin, la costante di Planck ecc. e rivela in un contesto unitario e rigoroso, chi sia l’attore principale di tutti gli avvenimenti fisici: quel mattone primigenio che tramite la costante di struttura fine dà luogo alla diversificazione della fenomenologia del mondo atomico. A ragione si può affermare che questo libro sia indispensabile per capire cos’è la luce, cos’è la materia, cos’è la gravità e può arricchire qualsiasi biblioteca di cultura scientifica.
