The Theory of Everything: The Origin and Fate of the Universe Author: Stephen W. Hawking This book consists of a compilation of several lectures by Stephen Hawking. Hawking attempts to explain sophisticated and complex mathematical ideas in an unsophisticated, perhaps childlike way. He briefly covers the history of ideas about the universe from Aristotle, Augustine, Newton, Einstein, Hubble, and Feynman. He then explains the Big Bang, black holes, and space-time and incorporates these thoughts into the search for a unified theory of everything. Although Hawking does not announce the arrival of the Theory of Everything, he does explain, in simple metaphors, the flavor of what such a theory would encompass. One of the more important concepts of his involves the idea that the "beginning" of the universe does not necessarily imply a singularity . If we wish to hold consistency with quantum mechanics (the most successful scientific theory to date) then a no-boundary condition would best describe the beginning. Needless to say, this contradicts many religious ideas about a creation (although he empathizes that these ideas represent only a proposal). Hawking represents one of the most brilliant theoretical scientists of our time. He advocates the idea of communicating the ideas theoretical science in a way to make it understandable, in principle, to everyone, not just scientists. Hawking has an acute awareness of the religious impact of his theoretical studies and explains in a clear but inoffensive way that the universe does not confirm to the common belief of an all powerful Creator. A few quotes from the book: • An expanding universe does not preclude a creator, but it does place limits on when He might have carried out his job. • We now know that our galaxy is only one of some hundred thousand million that can be seen using modern telescopes, each galaxy itself containing some hundred thousand million stars. • In the case of the whole universe, one can show that this negative gravitational energy exactly cancels the positive energy of the matter. So the total energy of the universe is zero. • One could say: "The boundary condition of the universe is that it has no boundary." The universe would be completely self-contained and not affected by anything outside itself. It would be neither created nor destroyed. It would just be. • If the universe is really completely self-contained, having no boundary or edge, it would be neither created nor destroyed. It would simply be. What place, then, for a creator? • Our aim is to formulate a set of laws that will enable us to predict events up to the limit set by the uncertainty principle. • If the no boundary proposal is correct, He [God] had no freedom at all to choose initial conditions..

Representation and Metaphysics Proper
Richard B. Wells ©2006 CHAPTER 4 First Epilegomenon: Representation and Metaphysics Proper The pursuit of wisdom has had a two-fold origin. Diogenes Laertius § 1. Questions Raised by Representation The outline of representation presented in Chapter 3 leaves us with a number of questions we need to address. In this chapter we will take a look back at our ideas of representation and work toward the resolution of those issues that present themselves in consequence of the theory as it stands so far. I call this look back an epilegomenon, from epi – which means “over” or “upon” – and legein – “to speak.” I employ this new term because the English language seems to have no word that adequately expresses the task at hand. “Epilogue” would imply logical conclusion, while “summary” or “epitome” would suggest a simple re-hashing of what has already been said. Our present task is more than this; we must bring out the implications of representation, Critically examine the gaps in the representation model, and attempt to unite its aggregate pieces as a system. In doing so, our aim is to push farther toward “that which is clearer by nature” although we should not expect to arrive at this destination all in one lunge. Let this be my apology for this minor act of linguistic tampering.1 In particular, Chapter 3 saw the introduction of three classes of ideas that are addressed by the division of nous in its role as the agent of construction for representations. We described these ideas as ideas of the act of representing.

Everything from elementary particles to celestial bodies, from electromagnetic wave to gravity is in eternal motions, which dissects only to circle. Since everything is described only by trigonometry. Without trigonometry and mathematical circle, the science cannot indicate all the beauty of harmonic universe. Other method may be very good, but it is not perfect. Some part is very nice, another part is problematic. General Theory of Relativity holds that gravity is geometric. Quantum Mechanics describes all particles by wave function of trigonometry. In this paper using trigonometry, particularly mathematics circle, a possible version of the unification of partial theories, evolution history and structure of expanding universe, and the parallel universes are shown.

Toward a Theory of Everything? Exploring at the Edges of the ERM Construct
Toward a Theory of Everything? Exploring at the Edges of the ERM Construct Dr. Kathleen Locklear 2012 Enterprise Risk Management Symposium April 18-20, 2012 © 2012 Casualty Actuarial Society, Professional Risk Managers’ International Association, Society of Actuaries Toward a Theory of Everything? Exploring at the Edges of the ERM Construct Dr. Kathleen Locklear Call Paper Submitted for the 2012 ERM Symposium April 18-20, 2012 Abstract During the past 10 years, enterprise risk management (ERM) has evolved considerably into a best practice approach for identifying, managing and monitoring risk across an entire organization. At the level of theory, ERM standards and frameworks such as those created by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) and the International Organization for Standardization, have provided guidance and a direction forward. Nevertheless, there remains no single, universally accepted ERM framework. At times, the multiplicity of approaches to ERM can produce confusion, leaving companies and practitioners alike wondering which method is “right.” Moreover, despite advances in ERM theory and practice, transboundary risk, extreme events and emerging risk continue to stretch ERM to its limits. This “stretching,” in combination with other observations regarding the current state of ERM theory and practice, suggest limitations in the ERM paradigm as it exists today. This raises several compelling questions, which are the focus of this paper. 1) What is the current state of the ERM paradigm,

Musings on the Theory of Everything and Reality (PDF)
Lecture Notes 7: Musings on the Theory of Everything and Reality 1 Is a \Theory of Everything" Even Possible? In Lecture Notes 6, I described the ongoing quest of theoretical physicists to day in uncovering the “theory of everything” that describes Nature. Nobody knows yet what that theory is — it would have to somehow reconcile the conflict between quantum theory and general relativity, i.e., it would have to be a theory of “quantum gravity” — but people are certainly trying, and many optimistic people even feel that we’re “almost there.” I personally have no idea if we’re close at all, because I am definitely not an expert on any candidate theory of quantum gravity. However, I do feel that we’ve come a long way in the past 100 years. And, when I marvel at the progress we’ve made, it makes me feel that, some day, we will finally have the correct theory of quantum gravity. Whether that day is 50 years from now or 500 years I won’t try to guess. But it seems like we can understand the Universe. In deed, as Einstein once mused: “The most incomprehensible thing about the Universe is that it is comprehensible.” But is the Universe really comprehensible? We can certainly understand aspects of the Universe today, but could we someday understand everything about it? The prospect of understanding everything — not only the laws of physics, but also the state of every single object in the (possibly infinite) Universe — probably seems rather bleak. After all, we humans are only only small, finite systems in an incredibly vast (possibly infinite) Universe, so maybe complete knowledge of every system in the Universe is impossible to attain.

Augmenting the Reality of Everything
Augmenting the Reality of Everything Augmented reality isn’t just “a game thing.” It will quickly appear within trips, experiences and transactions in both our personal and business lives, in the form of what we call journeys. Organizations across industries need to begin weaving immersive technologies into customer, employee, supplier and partner interactions – or risk irrelevance in the years to come. By Robert Hoyle Brown Executive Summary It’s morning – time to get up and go to work. You put on your spectacles, just like millions have done since Benjamin Franklin invented bifocals generations ago. But yours are no ordinary eyeglasses. They’re a gateway into all the journeys you’ll take throughout the day – big and little, personal and work, and everything in between. And when your work is done, it’s also fun to leave some time for chasing phantom zombies around the neighborhood. Welcome to the coming world of augmented reality (AR), a technological watershed preceded by years of trial and error, goofy-looking headgear, brawls with “glassholes”1 and sci-fi detours into isolated realms of virtual reality (VR). Those who write off AR as “just a game thing” do so at their own peril. AR will remake experiences in our work and personal lives in important – and yes, fun – ways. Many leading companies – from film, travel, healthcare, retail, automotive, education and heavy equipment industries – have moved beyond pilot phases and are deriving real results from early initiatives applying this profound visualization tool. Whether it’s used to help electric utilities install and optimize wind turbines, bring smiles to the elderly in dreary nursing homes,2 enhance factory floor safety for industrial workers, design a new skyscraper (or even place your next tattoo), early adopters are using AR to orchestrate the future of work – and play – experiences.

Metaphysics: a Contemporary Introduction: Third Edition
Metaphysics Metaphysics: A contemporary introduction is for students who have already done an introductory philosophy course. Michael J. Loux provides a fresh look at the central topics in metaphysics, making this essential reading for any student of the subject. This third edition is revised and updated and includes two new chapters on Time and Causation. Topics addressed include: • the problem of universals • the nature of abstract entities • the problem of individuation • the nature of modality • identity through time • the nature of time • the Realism/anti-Realism debate Wherever possible, Michael J. Loux relates contemporary views to their classical sources in the history of philosophy. As an experienced teacher of philosophy and an important contributor to recent debates, Loux is uniquely qualiﬁed to write this book. The third edition retains the student-friendly features of previous editions: • chapter overviews summarizing the main topics of study • examples to clarify difﬁcult concepts • annotated further reading at the end of each chapter • endnotes and a full bibliography Michael J. Loux is Shuster Professor of Philosophy at the University of Notre Dame. He is also editor of Metaphysics: Contemporary Readings, designed to accompany this textbook and also published by Routledge. His book Substance and Attribute (1978) is one of the major metaphysics books of recent years. Routledge Contemporary Introductions to Philosophy Series editor: Paul K. Moser Loyola University of Chicago This innovative, well-structured series is for students who have already done an introductory course in philosophy. Each book introduces a core general subject in contemporary philosophy and offers students an access- ible but substantial transition from introductory to higher-level college work in that subject.

Stop All the Clocks
COMMENT SPRING BOOKS (My quick check online showed that pairs from three species of cotinga sell for US$25 to $45. I easily found feathers on sale from birds on the International Union for Conservation of Nature’s Red List of Threatened Species.) US thief Willie Sutton allegedly said that he robbed banks because “that’s where the money is”. Museums are where the feathers are. In July 2009, senior curator Mark Adams found the drawers with missing specimens; 16 months later, Rist was caught. He pleaded guilty to burglary and money-laundering. The court fined him £125,150 (US$200,000 at the time), of which he had about 10%. He also got a mere 12-month suspended sentence, owing to a diagnosis of Asperger’s syndrome (an autism spectrum disorder). Of the 299 skins stolen, police retrieved only 102 with the labels intact. More had been stripped of the essential data that such labels provide, and 106 were missing. John- son’s exhaustive sleuthing tracked down some feathers in 2016, but nothing more. Museum specimens are a unique, con- textualized archive, as Robert Prys-Jones, a scientific associate at the Natural History Museum, makes clear in the book. They hold information about where and when species lived, who collected them and perhaps why; and they can be studied for visual and genetic clues. But after interviews with individuals PHYSICS in the fly-tying community, Johnson feels that only some are horrified by the theft. His investigations revealed that the bulk of the birds “dissolved into the bloodstream of the Stop all the clocks feather underground”, some realms of which seemed to trade in endangered species and flout the Convention on International Trade Andrew Jaffe probes Carlo Rovelli’s study arguing in Endangered Species of Wild Fauna and that physics deconstructs our sense of time.

Why They Should Be Called Theories of Everything Physical Instead
On the Theories of Everything: Why they should be called theories of everything physical instead Ho Manh Tung Ritsumeikan Asia Pacific University, Beppu, Oita, Japan September 26, 2020 The claim, or at least the hope, of all theories of everything in physics such as Wolfram’s physics program1 or Eric Weinstein’s Geometric Unity2,3, is that there is a finite set of physical laws, from which the entire physical universe can be reproduced. A stronger claim is that from this set of laws, the universe, including all social interactions, will be reproduced. In my opinion, in such a claim or an aspiration of these supposedly competing theories of everything, the authors sneak in a physicalist assumption. That one claims that everything is physical, including mind4. It seems quite far-fetched that from Wolfram’s hypergraphs and Weinstein’s equations, spring both the physical universe (i.e., the stars, the black holes, the galaxies, etc.) and the mental universe/universes that include every person’s phenomenology. If indeed all the complexities of minds can be reduced to simply certain arrangements of atoms and flows of information, the view of patternism5, it is conceivable that the right kind of computations can indeed simulate real people with their consciousness intact. However, no one can be sure if this is true. One can simply entertain some of the major thought experiments in the literature of the philosophy of mind to see why the hard problem of consciousness poses a significant challenge to the stronger claim of the theories of everything: thought experiments such as Frank Jackson’s Epiphenomenal Qualia’s “Mary’s Room,”6 David Chalmers’ “The philosophical zombie,”7 John Searl’s “The Chinese Room,”8 Thomas Nagel’s “What is it like to be a bat?”9 Philosopher Galen Strawson has eloquently and clearly restated the mind and body problem by asking what “physical” really means, in which he raises a point that we are not even sure what matter is or what its relationship with mind is.
