Baggerman Furthermore, it is so engrained in our daily lives that we have forgotten it is a paradigm, not fact. However, there are some problems with it: first, there is no satisfactory explanation for why we have consciousness and experience meaning in our The lives. Second, modern-day physics tells us that observations Universe, depend on characteristics of the observer at the large, cosmic Dialogues on and small, subatomic scales. Third, the ongoing humanitarian and environmental crises show us that our world is vastly The interconnected. Our understanding of reality is expanding to Universe, incorporate these issues. In The Universe, Life and Everything... our Changing Dialogues on our Changing Understanding of Reality, some of the scholars at the forefront of this change discuss the direction it is taking and its urgency.

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. -
The Discovery of Asymptotic Freedom
The Discovery of Asymptotic Freedom The 2004 Nobel Prize in Physics, awarded to David Gross, Frank Wilczek, and David Politzer, recognizes the key discovery that explained how quarks, the elementary constituents of the atomic nucleus, are bound together to form protons and neutrons. In 1973, Gross and Wilczek, working at Princeton, and Politzer, working independently at Harvard, showed that the attraction between quarks grows weaker as the quarks approach one another more closely, and correspondingly that the attraction grows stronger as the quarks are separated. This discovery, known as “asymptotic freedom,” established quantum chromodynamics (QCD) as the correct theory of the strong nuclear force, one of the four fundamental forces in Nature. At the time of the discovery, Wilczek was a 21-year-old graduate student working under Gross’s supervision at Princeton, while Politzer was a 23-year-old graduate student at Harvard. Currently Gross is the Director of the Kavli Institute for Theoretical Physics at the University of California at Santa Barbara, and Wilczek is the Herman Feshbach Professor of Physics at MIT. Politzer is Professor of Theoretical Physics at Caltech; he joined the Caltech faculty in 1976. Of the four fundamental forces --- the others besides the strong nuclear force are electromagnetism, the weak nuclear force (responsible for the decay of radioactive nuclei), and gravitation --- the strong force was by far the most poorly understood in the early 1970s. It had been suggested in 1964 by Caltech physicist Murray Gell-Mann that protons and neutrons contain more elementary objects, which he called quarks. Yet isolated quarks are never seen, indicating that the quarks are permanently bound together by powerful nuclear forces. -

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. -

He Has Made Everything Appropriate in Its Time. He Has Also Set Eternity in Their Heart
HE HAS MADE EVERYTHING APPROPRIATE IN ITS TIME. HE HAS ALSO SET ETERNITY IN THEIR HEART. ECCLESIASTES 3:11A PURPOSE OF THE HEART DATE WEEK OVERVIEW KEY VERSE August 8-9 10 of 10 Ecclesiastes 3 Ecclesiastes 3:11a Throughout the summer we have looked at the Story of Purpose as it pertained to various aspects of life. In Ecclesiastes 3 Solomon writes about the extremes of life reminding the reader that there is a purpose to everything under heaven. We have looked at the purpose of different things over the last few months. Whether we are looking at the purpose of work, home, community, freedom, or valleys, it all comes down to the heart of the matter. The heart is the most vital of all physical organs as it pumps blood to the entire body. Without the heart doing what it is designed to do, the other organs in the body have no chance of accomplishing their purpose. The purpose of the heart is to give life to the body. If the heart does not fulfill its purpose; if the blood ceases to be pumped throughout the body the result is death. The heart is just as important in the spiritual side of life. We are to love the Lord with all of our heart. The heart is the core of our being both physically and spiritually. Proverbs 4:23 says, “Watch over your heart with all diligence, for from it flow the springs of life.” Solomon realized the importance and significance of the heart both physically and spiritually. -
Everything Is a DCF Model a Mantra for Valuing Cash-Generating Assets
Counterpoint Global Insights Everything Is a DCF Model A Mantra for Valuing Cash-Generating Assets CONSILIENT OBSERVER | August 3, 2021 Introduction AUTHORS Matt Levine is a very talented journalist who writes the Money Stuff Michael J. Mauboussin [email protected] opinion column for Bloomberg. A trained lawyer and former banker, Levine is smart, entertaining, and informative.1 He also likes to use Dan Callahan, CFA a handful of themes to create context for his observations about [email protected] business, law, and the markets. One of his favorites is “everything is securities fraud.”2 The basic idea is that whenever something bad happens to a company causing its stock to decline, someone will accuse the management of acting nefariously. In the same vein, we want to suggest the mantra “everything is a DCF model.” The point is that whenever investors value a stake in a cash-generating asset, they should recognize that they are using a discounted cash flow (DCF) model. This is important because an investor, from a venture capitalist to a manager with a portfolio of large-capitalization stocks, owns partial stakes in businesses. The value of those businesses is the present value of the cash they can distribute to their owners. This suggests a mindset that is very different from that of a speculator, who buys a stock in anticipation that it will go up without reference to its value. Investors and speculators have always coexisted in markets, and the behavior of many market participants is a blend of the two. But it is useful to keep in mind that these are separate activities.
