George Placzek: A Nuclear Physicist’s Odyssey
This book presents the first detailed biography of George Placzek -- an outstanding physicist, a participant in the Manhattan Project who stood at the very inception of nuclear physics and the subsequent development of the nuclear bomb in the course of the WWII. In the 1930s, George Placzek was known as an adventurous person with a sharp sense of humor, a tireless generator of novel physics ideas which he generously shared with his colleagues. Born in Brno (now Czech Republic) into a wealthy Jewish family, he lost all his relatives to Holocaust, casting a tragic shadow on his life.Placzek's scientific career began in the late 1920s when the quantum revolution was almost over, but nuclear physics was still at its infancy. He established personal and scientific relations with the creators of quantum mechanics, such as Heisenberg in Leipzig and Niels Bohr in Copenhagen. In Rome, he worked with Fermi, and in Copenhagen he became a part of Bohr's nuclear physics team which dominated nuclear theory at that time. The scope of Placzek's pilgrimage around world physics centers in the 1930s was unique among his colleagues. In January 1939, George Placzek managed to emigrate from Europe to the US, and became a part of the British Mission within the Manhattan Project. His physical insights were instrumental in advancing from the basic discoveries on nuclear chain reactions to the Trinity experiment, Hiroshima and Nagasaki.This book is a unique compilation of a large number of previously unknown and unpublished documents from private and university archives, police reports, etc. Placzek's correspondence with the leadership of the Hebrew University in 1934, the 1937 NKVD interrogation files of Konrad Weisselberg, recollections of Ella Andriesse as well as the Zurich Police report of 1956 detailing the circumstances of Placzek's death in a Zurich hotel are illuminating as they shed light on poorly known pages of his life.
Principles of Classical Thermodynamics: Applied to Materials Science
The aim of this book is to present Classical Thermodynamics in a unified way, from the most fundamental principles to non-uniform systems, thereby requiring the introduction of coarse graining methods, leading for instance to phase field methods. Solutions thermodynamics and temperature-concentration phase diagrams are covered, plus also a brief introduction to statistical thermodynamics and topological disorder. The Landau theory is included along with a general treatment of multicomponent instabilities in various types of thermodynamic applications, including phase separation and order-disorder transitions. Nucleation theory and spinodal decomposition are presented as extreme cases of a single approach involving the all-important role of fluctuations.In this way, it is hoped that this coverage will reconcile in a unified manner techniques generally presented separately in physics and materials texts.
Soviet Atomic Project, The: How the Soviet Union Obtained the Atomic Bomb
The book describes the lives of the people who gave Stalin his weapon -- scientists, engineers, managers, and prisoners during the early post war years from 1945-1953. Many anecdotes and vicissitudes of life at that time in the Soviet Union accompany considerable technical information regarding the solutions to formidable problems of nuclear weapons development.The contents should interest the reader who wants to learn more about this part of the history and politics in 20th century physics. The prevention of nuclear proliferation is a topic of current interest, and the procedure followed by the Soviet Union as described in this book will help to understand the complexities involved.

Riding on a Ray of LightNew Concepts in the Study of Light, Matter and Gravity
A Conceptual Breakthrough in Our Understanding of Fundamental Nature of Matter and Energy!! A lot of questions have bothered science for a long time! What is a photon? Why does light behave both like a particle and a wave? How does light transform into matter? What is gravity? What is Big Bang and what came before it? The list is endless ... Riding on a Ray of Light describes a working model, called the Negentropic Model, which describes the fundamental nature of matter and energy. The negentropic model, formulated as a single theoretical principle based on the current scientific concepts, describes the precise structure of photon along with an explicit mechanism of generation of a light. It also describes the precise nature of matter and its formation in nature along with the intriguing nature of gravity. Alongside, this model explains the underlying meaning of some of the weirdest quantum phenomena such as wave-particle duality. In addition, by proposing the concept of 'dark protons', negentropic model allows us to delineate the precise nature of dark matter and dark energy, and this knowledge lets us peep into the depths of black holes to understand their true nature. Basing on these findings, the concept of Big Bang is revised and a brand-new concept of Differential Big Bang proposed! Riding on a Ray of Light presents the most comprehensive model in fundamental physics proposed so for, answering many of the hitherto unanswered questions in particle physics and cosmology, which really helps us to work towards a Theory of Everything !

Prove Physics
Since it was developed, Newton's law of gravitation and many other laws of physics cannot be derived from one grand underlying principle. Deriving Newton's law of gravitation or Einstein general relativity theory, would mean that gravity emerges from something else and that would mean that the only known Newton's law of universal gravity is no longer a fundamental law of physics. Although this might be true, I believe that everything must have an origin. I believe that there is a fundamental universal physical law from which all other known physical laws can be deduced. I also believe that the laws of physics are not picked at random but there exists an underlying principle from which they can be derived with ease. Failure for some minds to grasp this principle doesn't mean that it doesn't exist. Because I was used to deriving and proving formulae in pure math, I didn't like the way the laws of physics were presented to me without proof. A physics tutor would just write down a set of physical laws without proof. There are so many physics books which still do the same thing. Being curious and passionate to finding out how I could derive all the laws of physics from one single equation is proof that this book would have never existed in the first place if had not discovered the hidden principle that underlies all physics.

Introduction to Soft Matter Physics
Soft matters differ from hard ones essentially due to former's relatively weak interaction which is comparable to kBTrm (Trm = room temperature) -- this results in the major characteristics of soft matters such as "strong reactions upon weak actions".Developed over a period of 10 years through soft matter physics lectures for both graduate and undergraduate students in Fudan University, this textbook not only concentrates on the basic interactions inside soft matters through a reductionist approach, but also introduces the exploratory works on the complexity of soft matters in methods of system science.Other important topics in soft matter physics which are included involve static and dynamic electrorheological (ER) effects -- an important 'model animal' in the subject, granular media -- which explains the thermodynamics of sands and its dynamics, and the Onsager principle of least energy dissipation rate which has been adapted in this textbook to see how it governs the optimal paths of a system's deviation from and restoration to equilibrium.The subject of soft matter physics is still in its infancy, making it highly exciting and attractive. If you like a challenging subject, you will most certainly fall in love with soft matter physics at first read!

Joint Venture Agreements in the Qatari Gas IndustryA Theoretical and an Empirical Analysis
This book addresses a question of importance for both theory and practice: Why are joint venture agreements preferred over other types of agreements such as concession agreements, service contracts, and production sharing agreements in the Qatari gas industry? On a theoretical level, the author analyses this decision-making process by developing an approach that integrates a micro-level analysis, more specifically within international oil companies, with a macro-level analysis that spring from the organisational culture of the Qatari gas industry. At the micro level, the author proposes John Dunning's eclectic paradigm (as one set of theoretical ideas) to explaining one element of the decision-making process leading to the preference for joint venture agreements, that is, that of international oil companies. At the macro-level, the author proposes Antony Giddens' structuration theory (as another set of theoretical ideas) to explaining another part of this decision-making process, that is, how it is being shaped by the organisational culture of the Qatari gas industry. On an empirical level, the proposed book applies a combination of a micro-economic approach such as Dunning's eclectic paradigm with a macro-sociological approach such as Giddens' structuration theory by empirical investigation. Grounded on a qualitative strategy that focuses on the meaning-making which brings together different perspectives of this decision-making process including those of international oil companies and the organisational culture of the Qatari gas industry, the proposed book utilises a case study design, named the case of the Qatari gas industry. The author employs a triangulation of data collection techniques to access empirical data: analysing official documents and semi-structured interviews (a sample of the interview questions are included in an appendix to the proposed books). In line with the qualitative nature of this proposed book, a thematic Analysis is adopted to interpret data based on Dunning's eclectic paradigm at the micro level and Giddens' structuration theory at the macro level. In doing so, this book connects theory with practice by investigating the preference for joint venture agreements in the case of the Qatari industry by the combined application of one of the most effective frameworks for explaining foreign direct investment, named Dunning's eclectic paradigm along with the most complex sociological framework that offers a rich definition of organisational culture, named Giddens' structuration theory. Audience could include academics, professionals, and graduate and senior undergraduate students.
How to Study Physics
Physics is a basic science. It comes into play in the field of Medicine, Biology, Architecture, Technology, Earth and Environmental Sciences. It answers many questions as to "how?" or "why?". Many possibilities opened up to promote the progress of mankind, and to improve the world we live in. Yet, not everyone has an opportunity to study physics at school or college. This, then, is the excuse for a book on how to study Physics.Learning Physics takes work, it's time consuming, and there are no shortcuts to solving problems. This is a guidebook to enhance your abilities to solve physics problems. It is the main objective of an education to train people to think clearly about what they want to achieve in life. The type of questions we will be discussing are not mentioned in most Physics textbooks. The questions we will discuss relate to your personal life, and to prepare you to succeed in a Physics course.
La realt? del tempo e la ragnatela di Einstein - II edizione
Il pi羅 grande mistero di sempre, l'enigma del tempo, 癡 stato come un quasar accecante per il creatore della Teoria della Relativit?. In effetti, non v'癡 stato pensatore significativo, dall'antichit? ai nostri giorni, che non abbia fatto del confronto con il mistero del tempo un momento essenziale del suo stesso filosofare. Gi? ai tempi di Plotino il problema del tempo era ritenuto "vecchio" e continuamente risollevato. Pensare il tempo 癡 come arare il mare. Nonostante ci簷 il XX secolo ha conosciuto una definizione inedita e operazionale ad opera di Einstein, il quale spoglier? la nozione di tempo da ogni contenuto metafisico e lo render? ontologicamente nullificabile. Ecco il verdetto nella nostra epoca: "il tempo non esiste". Eppure non sono mancati i pensatori che hanno tentato di nuotare controcorrente lanciando un guanto di sfida al "cronocida", al demolitore dell'assoluto. Questi momenti da brivido vengono qui raccolti, rendendo vivo e attuale il volto filosofico di ogni dissidente. Esso interessa gli esperti del settore, ma anche ogni mente indagatrice della verit? storica. Il lettore interessato alle idee fondamentali della fisica e della filosofia trover? qui soddisfazione. Cos穫 come trover? la radice ultima della nostra Weltanschaaung contemporanea.

Paradigmenwechsel. Gr羹nde f羹r den sp瓣ten Erfolg des kopernikanischen Modells
Studienarbeit aus dem Jahr 2016 im Fachbereich Astronomie, Note: 1,0, Universit瓣t Konstanz, Veranstaltung: Proseminar FNZ, Sprache: Deutsch, Abstract: Als Schl羹sselereignis wird im Wege der hier vorliegenden Hausarbeit die kopernikanische Wende beleuchtet, im Wege derer auch die Erkenntnisgewinnung, welche bis dahin durch die Methode der Scholastik erfolgte, durch die Empirie Abl繹sung fand. Der Wandel zur innovativen, experimentell-empirischen Forschung ergab sich aus der neuen Verbindung des traditionellen gelehrten Wissens ("scientia" vor allem Mathematik, Astronomie) mit den artes mechanicae, den handwerklich-technischen, "unfreien", bisher sozial gering gesch瓣tzten K羹nsten. Aufgrund des gesetzten Rahmens dieser Hausarbeit, sei erw瓣hnt, dass die Erkenntnistheorie und deren Methoden kein Bestandteil der vorliegenden Arbeit darstellen. Die durch den Begriff "wissenschaftliche Revolution" implizierte z羹gige Wende mag dar羹ber hinwegt瓣uschen, wie langwierig und beschwerlich der Weg der kopernikanischen Idee eines heliozentrischen Weltbilds bis zu dessen Akzeptanz tats瓣chlich war. Demnach widmet sich das zweite Kapitel dieser Hausarbeit zun瓣chst einem allgemeinen Teil, in dem es vor allem um das Begriffsverst瓣ndnis zur "wissenschaftlichen Revolution" geht, wie es im Wissenschaftshistorischen Kontext gebr瓣uchlich ist. Im dritten Kapitel dieser Arbeit geht es konkret um die Ausarbeitung der dieser Hausarbeit zugrunde gelegten Fragestellung, n瓣mlich welche Widerst瓣nde das kopernikanische Modell auf seinem Wege zu 羹berwinden hatte und welche konkreten Gr羹nde sich daf羹r identifizieren lassen, dass das kopernikanische Modell sich weit nach seiner Ver繹ffentlichung durchsetzen konnte. In der Schlussbetrachtung wird die Ausarbeitung in zusammengefasster Form dargestellt.
Planetare Systeme der Erde 2
Das in Band 1 entwickelte Modell wird auf die Gittersysteme der Radi瓣sthesie angewendet - das Benker-Kuben-System, das Hartmann-Gitter, das Curry-Netz und die Wittmannschen Polpunkte. Die Gittersysteme k繹nnen aus dem Grundfeldmodell rein physikalisch/mathematisch abgeleitet und berechnet werden. Es kann gezeigt werden, dass alle Gittersysteme der Radi瓣sthesie Subsysteme des magnetischen Erdfeldes sind und als ein Planetares System dargestellt werden k繹nnen. Daher k繹nnen den Gittern Frequenzen zugeordnet werden und es kann ein Ger瓣t bzw. ein Experiment angegeben werden, mit dem sich die Gitter als messbare elektrotechnische Gr繹?en erweisen und somit verifizierbar und quantifizierbar sind. Dar羹ber hinaus besch瓣ftigt sich das Buch mit der Abh瓣ngigkeit von Lebewesen von elektromagnetischen Feldern und mit dem Ph瓣nomen des "Mutens" das als Wahrnehmung von Impedanz瓣nderungen des magnetischen Feldes erkl瓣rt werden kann. Durch die Invertierung der Wahrnehmung kommt es zu es hier zu der subjektiven Ansicht, dass da etwas sein m羹sste. Bei der Annahme einer Existenz von "Erdstrahlen" handelt es sich daher um eine subjektive Fehlinterpretation einer realen Wahrnehmung. Die Laufbrett- und R繹hren-Versuche von Betz und K繹nig werden behandelt, sowie auch die Kritik und alternativen Vorstellungen des Skeptikers Lambeck. Es kann ein Versuch angegeben werden mit dem das Muten und seine Funktionsweise belegt werden kann und mit dessen Hilfe sich sogenannte "Sensitive" finden lassen.
The Essence of Eternity
This book develops in detail quaternion and octonion theories that lead directly to the Unified SuperStandard Theory for our universe. It is based on a Mathematical Picture Langauge implemented with the psiphi figures of Pythagoras harkening back to the beginning of Science. Numerous topics including: particle-dimension duality, functionals, quantum entanglement, and so on.
New Trends in Quantum Electrodynamics
This book collects research and review articles covering some recent trends in nonrelativistic quantum electrodynamics, specifically the interaction of atoms or molecules within the quantum electromagnetic radiation field and the related physical effects. Specific topics covered are: two- and three-body dispersion interactions between atoms and molecules, both in the nonretarded van der Waals and the retarded Casimir-Polder regime; vacuum field fluctuations of the electromagnetic field and their effect in atomic systems; dispersion interactions between uniformly accelerating atoms and relation with the Fulling-Davies-Unruh effect; dynamics of atomic systems under strong electromagnetic fields; symmetries in quantum electrodynamics; and open quantum systems.
Astrophysics’ Paradigm Shift
The universe is much simpler that we have been led to believe. Because of a fundamental cosmological error dating back to 1912, currently accepted astrophysics has built an elaborate structure of theories that are without foundation. The mythical "big bang" could not possibly have happened, galaxies are not retreating from us, we are not on a collision course with Andromeda, and both dark matter and dark energy are fictions. Inside this book you will find documented proof that these fanciful theories are invalid.Because of two mathematical oversights dating back to 1915, general relativity has become the currently accepted explanation for gravity. Unfortunately, this geometric theory of gravity is fatally flawed. Spacetime does not exist, gravity does not bend light, and gravitational waves do not exist. Inside this book you will discover significant facts about gravity that Einstein failed to consider.Scientific truth is never a matter of consensus. The currently prevailing view about the cosmos is just as much in error as it was during the era in which it was believed that the Sun revolved around the Earth.

Nuclear Technology Demystified
Nuclear Technology Demystified: Everything You Need to Know About Everything Nuclear is a detailed introduction for laypersons to all aspects of nuclear technology. It begins with discussions of the science behind nuclear systems, including some basic physics, atomic and nuclear structure, radiation, nuclear reactions, the fission chain reaction, and conversion of the heat produced by a reactor into electricity. Next, it puts nuclear power in context by surveying other energy sources and their pros and cons, and it discusses global warming as a reason to advocate the application of nuclear power as a carbon-free energy source. Finally, it describes specific nuclear technologies, including nuclear medicine, conventional and advanced nuclear reactors, nuclear fusion, the nuclear fuel cycle, nuclear waste disposal, and even nuclear weapons. It presents detailed summaries of the three major accidents that have been suffered by commercial nuclear power stations: Three Mile Island, Chernobyl, and Fukushima Daiichi.The reader needs no mathematical background. Some mathematical concepts are presented, but they are explained in simple terms that laypersons can understand. The book can be read cover-to-cover or used as a reference to search for specific topics. An extensive index helps the reader find specific items of interest.
Exogravitation
Exogravitation - John T Cullen's innovative theory for a new cosmology now has a name, based on his view that Dark Energy is nothing more than old fashioned gravity, but with a stunning twist. This is a challenging nonfiction work, a Gedankenexperiment (thought experiment) designed to tickle the imagination of cosmology professors and serious students.Exograv theory explains how it's possible that the universe is not only expanding, but doing so ever faster. Where is that energy coming from? The best that cosmologists (scientists who study the nature of the cosmos) have been able to devise is what engineers call a 'black box' approach. We know the inputs, we know the outputs, but we have no idea what goes on during the transformation or throughput. Dark energy cannot be created out of nothing - such an idea would violate the laws of thermodynamics. If there is Dark Energy in the system, where has it been hiding all these eons?John T. Cullen offers a radically new answer: exogravitation. We don't need to imagine hidden energy and impossible solutions. Instead, think about this: falling objects accelerate naturally and at easily predictable rates. Exogravitation (literally, 'gravitation from beyond') posits that our universe is one of infinitely many in a limitless Motherverse. The ambient gravitation of all those universes is pulling our universe apart in all directions, so our universe is falling (and falling apart) ever faster in all directions... The universe attenuates, meaning its particles grow ever father apart, until it reaches the Cosmopause. That is a spherical size at which our universe no longer has the gravitational strength to hold itself together. It vanishes like a soap bubble, and its dark gravitational matter (yes, that's the other component: Dark Matter) rejoins all the other fundamental dark matter of beyond... until random Brownian Motion (simple turbulence, as in pond water) starts gathering more and more matter to build the next universe.This book is filled with history as well as science. Among other things, we learn how the geocentric and heliocentric theories competed as long ago as ancient Greece in the age of Aristotle and Plato. We learn how an established theory is contantly being patched and stretched, until it can no longer compete with a sleek new theory. That's how we arrived at this wild new vision of Exogravitation in the 21st Century.
The Rise of the Scientist-Bureaucrat
"Perez Velazquez has written a little gem that I advise reading to anyone persuing a scientific career, as well as for the general public interested in the sociological aspects of science. It alerts the reader about the rise of a new type of scientist, buried in bureaucracy and financial issues. In contrast to past generations, this "new scientist" is sadly left with minimal time to dedicate to creative work. It studies the consequences of this state of affairs, the problems associated with peer reviewing, the dilemma of funding innovative research, the nature of corporate academic culture and the trivialization of scientific achievement by grant agencies and universities. It also provides possible solutions for these problems. All this is magnificently exemplified and documented, including personal experiences from the author and a touch of humor illustrated in the accompanying cartoons. Despite the humor, it is a serious piece of work that would also be useful for the conscientious academic worried about the difficulties of the current research scene."Marina Frantseva, MD, PhD Jose Luis Perez Velazquez is a Spanish biochemist/biophysicist. He has a degree in Biochemistry and a PhD in Molecular Physiology & Biophysics. His research activities are mainly in the fields of the brain-behaviour relation at a high level of description, seeking principles of biological organisation. He worked as a senior scientist at the Hospital for Sick Children in Toronto and was Professor at the University of Toronto, where he taught a graduate course on consciousness and self-awareness, which derived in part from his book The Brain-Behaviour Continuum (World Scientific). He also edited the book Coordinated Activity in the Brain (Springer), and edited special issues for The Journal of Biological Physics, Frontiers in Integrative Neuroscience and Frontiers in Computational Neuroscience. Currently he is a Research Scholar at the Ronin Institute, where he continues to investigate a possible global principle, a scheme that combines theoretical studies and experimental observations, aimed at conceptualizing how consciousness arises from the organization of matter.

Lyman-Alpha as an Astrophysical and Cosmological Tool
The hydrogen Lyman-alpha line is of utmost importance to many fields of astrophysics. This UV line being conveniently redshifted with distance to the visible and even near infrared wavelength ranges, it is observable from the ground, and provides the main observational window on the formation and evolution of high redshift galaxies. Absorbing systems that would otherwise go unnoticed are revealed through the Lyman-alpha forest, Lyman-limit, and damped Lyman-alpha systems, tracing the distribution of baryonic matter on large scales, and its chemical enrichment.We are living an exciting epoch with the advent of new instruments and facilities, on board of satellites and on the ground. Wide field and very sensitive integral field spectrographs are becoming available on the ground, such as MUSE at the ESO VLT. The giant E-ELT and TMT telescopes will foster a quantum leap in sensitivity and both spatial and spectroscopic resolution, to the point of being able, perhaps, to measure directly the acceleration of the Hubble flow. In space, the JWST will open new possibilities to study the Lyman-alpha emission of primordial galaxies in the near infrared. As long as the Hubble Space Telescope will remain available, the UV-restframe properties of nearby galaxies will be accessible to our knowledge. Therefore, this Saas-Fee course appears very timely and should meet the interest of many young researchers.
Zinc Sulphide Doped With Chromium. A Density Functional Theory Study
Bachelor Thesis from the year 2017 in the subject Physics - Theoretical Physics, grade: 4.00, University of Gujrat, course: physics, language: English, abstract: In this thesis, the electronic and magnetic properties of Cr doped wurtzite ZnS were studied by means of most advanced theoretical approach density functional theory (DFT) using generalized gradient approximation (GGA) functional and its correction factor GGA+U. Calculations have shown that doping of chromium at cationic sites of wurtzite zinc sulphide results in formation of a p-type semiconductor. Addition of hubbard term in the system causes an increase in band gap value and creates a gap between spin up and spin down channels for 3d states of chromium atoms. Chromium doped ZnS possess half metallic character because of excess in majority spin carriers than minority ones. Hopping of electrons in anti-bonding states of chromium atoms refers to the ferromagnetic behavior of the material. Half metallicity and ferromagnetic nature of the chromium doped wurtzite zinc sulphide makes this material a best candidate to be used in the field of spintronics. For the past few decades, work in semiconductor field appears to be of substantial importance in industrial world and offers a new direction to upgrade the standards of life. This novel era of semi-conductors has remake the history of science with its groundbreaking technology and has proven to be an extensively emerging field to handle even single atoms and molecules for manipulation and fabrications. In the recent years, material science has open a new window towards applicability of semiconductor devices in electronics, spintronics and many other branches of science. Presently, II-VI materials have gain much value because of their broad range of applicability in advance fields of science. These elements involve transition metals like zinc, cadmium and nonmetals like oxygen, sulphur, selenium, tellurium. Due to their wide band gap, these compounds possess sh

Noether’s Theorem and Symmetry
In Noether's original presentation of her celebrated theorem of 1918, allowances were made for the dependence of the coefficient functions of the differential operator which generated the infinitesimal transformation of the Action Integral upon the derivatives of the dependent variable(s), the so-called generalized, or dynamical, symmetries. A similar allowance is to be found in the variables of the boundary function, often termed a gauge function by those who have not read the original paper. This generality was lost after texts such as those of Courant and Hilbert or Lovelock and Rund confined attention to only point transformations. In recent decades, this diminution of the power of Noether's Theorem has been partly countered, in particular, in the review of Sarlet and Cantrijn. In this Special Issue, we emphasize the generality of Noether's Theorem in its original form and explore the applicability of even more general coefficient functions by allowing for nonlocal terms. We also look at the application of these more general symmetries to problems in which parameters or parametric functions have a more general dependence upon the independent variables.
A Fortunate Universe
Over the last forty years, scientists have uncovered evidence that if the Universe had been forged with even slightly different properties, life as we know it - and life as we can imagine it - would be impossible. Join us on a journey through how we understand the Universe, from its most basic particles and forces, to planets, stars and galaxies, and back through cosmic history to the birth of the cosmos. Conflicting notions about our place in the Universe are defined, defended and critiqued from scientific, philosophical and religious viewpoints. The authors' engaging and witty style addresses what fine-tuning might mean for the future of physics and the search for the ultimate laws of nature. Tackling difficult questions and providing thought-provoking answers, this volumes challenges us to consider our place in the cosmos, regardless of our initial convictions.

RelativityThe Special And General Theory, A Popular Exposition, Authorised Translation By
Relativity: The Special And General Theory, A Popular Exposition, Authorised Translation By Robert W. Lawson (Revised Edition) This book is a result of an effort made by us towards making a contribution to the preservation and repair of original classic literature. In an attempt to preserve, improve and recreate the original content, we have worked towards: 1. Type-setting & Reformatting: The complete work has been re-designed via professional layout, formatting and type-setting tools to re-create the same edition with rich typography, graphics, high quality images, and table elements, giving our readers the feel of holding a 'fresh and newly' reprinted and/or revised edition, as opposed to other scanned & printed (Optical Character Recognition - OCR) reproductions. 2. Correction of imperfections: As the work was re-created from the scratch, therefore, it was vetted to rectify certain conventional norms with regard to typographical mistakes, hyphenations, punctuations, blurred images, missing content/pages, and/or other related subject matters, upon our consideration. Every attempt was made to rectify the imperfections related to omitted constructs in the original edition via other references. However, a few of such imperfections which could not be rectified due to intentional\unintentional omission of content in the original edition, were inherited and preserved from the original work to maintain the authenticity and construct, relevant to the work. We believe that this work holds historical, cultural and/or intellectual importance in the literary works community, therefore despite the oddities, we accounted the work for print as a part of our continuing effort towards preservation of literary work and our contribution towards the development of the society as a whole, driven by our beliefs. We are grateful to our readers for putting their faith in us and accepting our imperfections with regard to preservation of the historical content. HAPPY READING!
