...I found this week’s modules and reading assignments incredibly helpful and highly motivating. Numerous concepts struck me as innovative and wise, and I can honestly say that I anticipate being able to implement the various methods and styles of effective leadership delineated in the course material. In particular, I am drawn to Transformational Leadership as well as the Theory of Quantum Leadership, the latter being an entirely new concept to me. Introduced in the 1990s, the Theory of Quantum Leadership posits that effective leaders realize the inevitability and constancy of change, collaborate with subordinates in the identification and realization of both goals and opportunities, and empower those around them to be effective and productive....

...In quantum statistics, a branch of physics, Fermi–Dirac statistics describes a distribution of particles over energy states in systemsconsisting of many identical particles that obey the Pauli exclusion principle. It is named after Enrico Fermi and Paul Dirac, who each discovered it independently, although Enrico Fermi defined the statistics earlier than Paul Dirac.[1][2] Fermi–Dirac (F–D) statistics applies to identical particles with half-integer spin in a system in thermodynamic equilibrium. Additionally, the particles in this system are assumed to have negligible mutual interaction. This allows the many-particle system to be described in terms of single-particle energy states. The result is the F–D distribution of particles over these states and includes the condition that no two particles can occupy the same state, which has a considerable effect on the properties of the system. Since F–D statistics applies to particles with half-integer spin, these particles have come to be called fermions. It is most commonly applied toelectrons, which are fermions with spin 1/2. Fermi–Dirac statistics is a part of the more general field of statistical mechanics and uses the principles of quantum mechanics.

...QUANTUM ELECTRODYNAMICS What is quantum electrodynamics? Sociology Anna C Jean – Guillaume Martin LCSW March 7, 2015 Professor Dr. Beverly Jackson Quantum electrodynamics (QED): Is the e area of physics devoted to the study of the interaction of matter (quantum particles) and light. It generally concerns itself with the wave (or field) aspects of nature. At the level of the quantum realm, QED demonstrates that everything is connected. The world is a vast web of relationships, with everything affecting everything else. The brain, blood, and bone of the body give way to invisible forces, fields, and particles whose interactions underlie not only the human body but all of matter. Molecules give way to atoms that dissolve into subatomic particles, so that our bodies are governed not only by the laws of everyday chemistry but also by the paradoxical principles of the physical body. History shows that most truly fundamental leaps forward in scientific understanding are shunned at first. Truly new insights are sometimes too radical an overturning of accepted theory or too threatening to business or academic interests to be evaluated impartially. You have only to think of germ theory, tectonic plate theory, quantum electrodynamics, and string theory to know that even ideas that are accepted widely in our day were dismissed as crackpot ideas by a previous generation of scientists. Over the years, as physicists’ explored wave-particle duality, the study of quantum physics...

...pproaches to interpreting quantum theory have been further explored and developed,[7][8][9] becoming quite popular. MWI is one of many multiverse hypotheses in physics and philosophy. It is currently considered a mainstream interpretation along with the other decoherence interpretations, the Copenhagen interpretation,[10] and deterministic interpretations such as the Bohmian mechanics. Before many-worlds, reality had always been viewed as a single unfolding history. Many-worlds, however, views reality as a many-branched tree, wherein every possible quantum outcome is realised.[11] Many-worlds claims to reconcile the observation of non-deterministic events, such as the random radioactive decay, with the fully deterministic equations of quantum physics. In many-worlds, the subjective appearance of wavefunction collapse is explained by the mechanism of quantum decoherence, which resolves all of the correlation paradoxes of quantum theory, such as the EPR paradox[12][13] and Schrödinger's cat,[1] since every possible outcome of every event defines or exists in its own "history" or "world". In lay terms, the hypothesis states there is a very large–perhaps infinite[14]–number of universes, and everything that could possibly have happened in our past, but did not, has occurred in the past of some other universe or universes.

...Jeff Knight GS1140 Problem Solving Theory 4/9/15 Teacher Module Three: Generating Solutions Using Futuring: As we progress in our technological world where everyone is interested in the next iPhone or Samsung Galaxy, quantum computers are still moving forward. It seems that only computer "nerds" seem to care and understand this wonder. What if all of the theories, concepts, and everything else that makes up what quantum computers are and will be, is presented in a way that everyone can understand. The way that quantum computers can be divided is into three main areas: quantum physics, quantum bits or (qubits), and their future goals. To better understand how quantum computers work, you need to start with what clearly defines a quantum computer: A quantum computer is a computer design which uses the principles of quantum physics to increase the computational power beyond what is attainable by a traditional computer. Quantum computers use two fundamental principles of quantum physics: superposition and entanglement. Quantum superposition is where the state of a physical system exists in all possible states at the same time. Then the physical system is only giving one state to the collection device. A good example of this is the famous Schrödinger's Cat, a thought experiment purposed by Erwin Schrödinger in 1935, where Schrödinger talks about having a cat in a closed box with a vial of poisonous acid with a hammer that will break the vial if any radioactivity is detected...

...Quantum mechanics (QM – also known as quantum physics, or quantum theory) is a branch of physics which deals with physical phenomena at nanoscopic scales, where the action is on the order of the Planck constant. It departs from classical mechanics primarily at the quantum realm of atomic and subatomic length scales. Quantum mechanics provides a mathematical description of much of the dual particle-like and wave-like behavior and interactions of energy and matter. It is the non-relativistic limit of quantum field theory (QFT), a theory that was developed later that combined quantum mechanics with relativity. In advanced topics of quantum mechanics, some of these behaviors are macroscopic (see macroscopic quantum phenomena) and emerge at only extreme (i.e., very low or very high) energies or temperatures (such as in the use of superconducting magnets). The name quantum mechanics derives from the observation that some physical quantities can change only in discrete amounts (Latin quanta), and not in a continuous (cf. analog) way. For example, the angular momentum of an electron bound to an atom or molecule is quantized.[1] In the context of quantum mechanics, the wave–particle duality of energy and matter and the uncertainty principle provide a unified view of the behavior of photons, electrons, and other atomic-scale objects. The mathematical formulations of quantum mechanics are abstract. A mathematical function known as the wavefunction provides information about the probability...

...which showed that Brownian movement can be construed as firm evidence that molecules exist. His research in 1903 and 1904 was mainly concerned with the effect of finite atomic size on diffusion phenomena.[88] General principles He articulated the principle of relativity. This was understood by Hermann Minkowski to be a generalization of rotational invariance from space to space-time. Other principles postulated by Einstein and later vindicated are the principle of equivalence and the principle of adiabatic invariance of the quantum number. 2] Main article: History of special relativity Einstein's "Zur Elektrodynamik bewegter Körper" ("On the Electrodynamics of Moving Bodies") was received on 30 June 1905 and published 26 September of that same year. It reconciles Maxwell's equations for electricity and magnetism with the laws of mechanics, by introducing major changes to mechanics close to the speed of light. This later became known as Einstein's special theory of relativity. Consequences of this include the time-space frame of a moving body appearing to slow down and contract (in the direction of motion) when measured in the frame of the observer. This paper also argued that the idea of a luminiferous aether – one of the leading theoretical entities in physics at the time – was superfluous.[89] In his paper on mass–energy...

...theoretical physics. After he graduated, he taught math and physics briefly. Planck completed his habilitation thesis and began lecturing in Munich without getting paid becuase he was waiting to be offered a new postion. He also furthered his work on the field of heat theory. Planck then became a professor at Berlin University and joined the Physical Society. As far as Plancks home life goes, he married and had four children. He was friends with theologian Adolf con Harnack and his home soon because a social center. Famous scientists like Albert Einstein and Otto Hahn all frequently visited. His wife died and he remaired and had his third son. Planck's two sons and two daughters all died. By the end of the 1920s, Bohr, Heisenberg, and Pauli had worked out the interpretation of quantum mechanics, but Planck rejected it. He expected that wave mechanics would render the quantum theory, even though this can not be the case. Further work only cemented quantum theory, even against Einstein's revulsions. He originated quantum theory, which won him the Nobel Prize in Physics in 1918. Max Planck made many contributions to theoretical physics, and is very famous for being the originator of quantum theory. He ended his life at Göttingen on October 4, 1947, but he has contributed so much for the...

... and Gravity .His theories on relativity paved the way for how science currently views time, space, energy, and gravity. Despite troubles in education and learning as a child, Einstein surpassed the odds and helped revolutionize science today. With his theories on relativity and gravity, Einstein would inspire other great scientists explain the unexplainable. Einstein also helped in the advancement of modern warfare, in the creation of the atomic bomb. Einstein's early work on the theory of relativity (1905) dealt only with systems or observers in uniform (unaccelerated) motion with respect to one another and is referred to as the special theory of relativity; among other results, it demonstrated that two observers moving at great speed with respect to each other will disagree about measurements of length and time intervals made in each other's systems, that the speed of light is the limiting speed of all bodies having mass, and that mass and energy are equivalent. In 1911 he asserted the equivalence of gravitation and inertia, and in 1916 he completed his mathematical formulation of a general theory of relativity that included gravitation as a determiner of the curvature of a space-time continuum. He then began work on his unified field theory, which attempts to explain gravitation, electromagnetism, and subatomic phenomena in one set of laws; the successful development of such a unified theory, however, eluded Einstein. In addition to the theory of relativity, Einstein...

...Quantum Quandaries by Heath Miller December 8th 2012 What if you could transfer a file faster than the speed of light on a connection with air-tight security? You could connect to a computer anywhere around the world in the blink of an eye and never have to worry about malicious activity. It seems impossible, right? Not necessarily. It could actually be done by using a quantum network. A true quantum network would be much faster than any connection we could implement with our current telecommunications hardware. In fact, a signal transferred over a true quantum connection wouldn’t take time to transfer whatsoever. It would literally arrive instantly, and would be sent using physical properties that dictate the mechanics of the entire universe. The implications of harnessing these phenomena are astounding. In a 2011 article written in by Lydia Leavitt it states that, “Researchers at the University of Copenhagen's Niels Bohr Institute have discovered what might be the key to completely secure data transfer, keeping particles ‘entangled’ for up to an hour. Until now, the link between two entangled systems could only be maintained for a fraction of a second. This development could enable a direct link between two systems of communication” (engadget.com, N.P.). This could mean incredible things for our communication systems. Don’t think that speed and convenience aren’t the only benefits we would reap either. There would be countless new tools and abilities that would...

...around the sun (although at the time they were discovered, it was thought that everything revolved around the earth); albeit all of these stars and planets were discovered before Galileo’s telescope. The tool still helped gain better calculations of the stars, which helped Galileo support Nicolaus Copernicus’ heliocentric (sun-centered) solar system as opposed to the geocentric (earth-centered) solar system that people in those times believed. With Isaac Newton, one of the most famous physicists, discovering most of laws of motion through his studies in astronomy, Philosophiae Naturalis Principia Mathematica, one of the greatest works in the Scientific Revolution, was born. From Newtonian physics, theories of fluid mechanics, electricity and magnetism, and most importantly, quantum mechanics. Further along the line of the history of telescopes, humans eventually needed to see deeper into space. This was revolutionary because now mankind wasn’t just looking up into the constellations and the movement of the sun and the moon, now they were actually...

Spacing and relationship between incoming and outgoing rays produces a virtual image which is identical to the real object. Refraction - light rays moving from one transparent medium to another may be bent, or refracted. The amount of refraction of light rays depends upon their angle of incidence in the same way reflection does, and also on specific properties of the different media and how fast light travels in each. 3) Know the evidence for the wave nature of light.

...p. 301). Olson (2002) explains how physics is divided into two main categories. He states that topics treated before the middle of the last decade of the nineteenth century are said to be parts of classical physics. On the other hand a group of topics that emerged after about 1895 is said to make up modern physics. Since physics is a broad area, in this essay, I specifically focus on one topic from modern physics, namely quantum physics. I will evaluate whether quantum physics can lead us to ‘Truth’. In this paper, ‘Truth’ refers to quantum events. First, I will portray how quantum events are filled with uncertainties; I will then list three answers given by physicists to explain why uncertainties are present. I will then move on to show how quantum physics offers conceptual parallels to ideas in religion. I will mainly discuss the role of holism character in quantum systems. Finally I will evaluate whether god is the reason for these indeterminacies. Barbour (2000) states that in the 1920s, Erwin Schrodinger devised the wave equation of quantum theory, which accounts accurately for the discrete energy levels of electrons in atoms. The equation enables us to calculate the probability that an electron will show up at a particular point when an observation is made. However, it is not possible to predict the...

...re-examined. We must come to terms with the physics of space-time--as is described by Einstein's general theory of relativity--and its relation to the fundamental theory of matter--as described by quantum theory. This leads us to employ a new physics of objective reduction: " OR" which appeals to a form of quantum gravity to provide a useful description of fundamental processes at the quantum/classical borderline (Penrose, 1994; 1996). Within the OR scheme, we consider that consciousness occurs if an appropriately organized system is able to develop and maintain quantum coherent superposition until a specific "objective" criterion (a threshold related to quantum gravity) is reached; the coherent system then self-reduces (objective reduction: OR). We contend that this type of objective self-collapse introduces non-computability, an essential feature of consciousness. OR is taken as an instantaneous event--the climax of a self-organizing process in fundamental space-time--and a candidate for a conscious Whitehead "occasion" of experience. How could an OR process occur in the brain, be coupled to neural activities, and account for other features of consciousness? We nominate an OR process with the requisite characteristics to be occurring in cytoskeletal microtubules within the brain's neurons (Penrose and Hameroff, 1995; Hameroff and Penrose, 1995; 1996). In this model, quantum-superposed states develop in microtubule subunit proteins ("tubulins"), remain coherent and recruit more...
