What is COPENHAGEN INTERPRETATION? What does COPENHAGEN INTERPRETATION mean? COPENHAGEN INTERPRETATION meaning - COPENHAGEN INTERPRETATION definition - COPENHAGEN INTERPRETATION explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. The Copenhagen interpretation is an expression of the meaning of quantum mechanics that was largely devised in the years 1925 to 1927 by Niels Bohr and Werner Heisenberg. It remains one of the most commonly taught interpretations of quantum mechanics. According to the Copenhagen interpretation, physical systems generally do not have definite properties prior to being measured, and quantum mechanics can only predict the probabilities that measurements will produce certain results. The act of measurement affects the system, causing the set of probabilities to reduce to only one of the possible values immediately after the measurement. This feature is known as wavefunction collapse. There have been many objections to the Copenhagen Interpretation over the years. Some have objected to the discontinuous jumps when there is an observation, the probabilistic element introduced upon observation, the subjectiveness of requiring an observer, the difficulty of defining a measuring device or to the necessity of invoking classical physics to describe the "laboratory" in which the results are measured. Alternatives to the Copenhagen Interpretation include the many-worlds interpretation, the De Broglie-Bohm (pilot-wave) interpretation, and quantum decoherence theories.

The many worlds theory proposes that the wavefunction never actually collapses. The observer simply follows one of those many possible paths into their present reality while all the other paths continue on independent of the observer. Each of these paths branches off into an entirely different reality. In this episode Matt discusses the details of the many worlds theory and why it’s not so far-fetched to think that our reality is simply one of an infinite number of realities existing within space time.

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. Quantum mechanics provides a substantially useful framework for many features of the modern periodic table of elements including the behavior of atoms during chemical bonding and has played a significant role in the development of many modern technologies. 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). For example, the angular momentum of an electron bound to an atom or molecule is quantized. In contrast, the angular momentum of an unbound electron is not quantized. 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, the wavefunction, provides information about the probability amplitude of position, momentum, and other physical properties of a particle. Mathematical manipulations of the wavefunction usually involve bra--ket notation which requires an understanding of complex numbers and linear functionals. The wavefunction formulation treats the particle as a quantum harmonic oscillator, and the mathematics is akin to that describing acoustic resonance. Many of the results of quantum mechanics are not easily visualized in terms of classical mechanics. For instance, in a quantum mechanical model the lowest energy state of a system, the ground state, is non-zero as opposed to a more "traditional" ground state with zero kinetic energy (all particles at rest). Instead of a traditional static, unchanging zero energy state, quantum mechanics allows for far more dynamic, chaotic possibilities, according to John Wheeler. The earliest versions of quantum mechanics were formulated in the first decade of the 20th century. About this time, the atomic theory and the corpuscular theory of light (as updated by Einstein) first came to be widely accepted as scientific fact; these latter theories can be viewed as quantum theories of matter and electromagnetic radiation, respectively. Early quantum theory was significantly reformulated in the mid-1920s by Werner Heisenberg, Max Born and Pascual Jordan, (matrix mechanics); Louis de Broglie and Erwin Schrödinger (wave mechanics); and Wolfgang Pauli and Satyendra Nath Bose (statistics of subatomic particles). Moreover, the Copenhagen interpretation of Niels Bohr became widely accepted. By 1930, quantum mechanics had been further unified and formalized by the work of David Hilbert, Paul Dirac and John von Neumann with a greater emphasis placed on measurement in quantum mechanics, the statistical nature of our knowledge of reality, and philosophical speculation about the role of the observer. Quantum mechanics has since permeated throughout many aspects of 20th-century physics and other disciplines including quantum chemistry, quantum electronics, quantum optics, and quantum information science. Much 19th-century physics has been re-evaluated as the "classical limit" of quantum mechanics and its more advanced developments in terms of quantum field theory, string theory, and speculative quantum gravity theories. https://www.youtube.com/watch?v=ZsVGut7G-dU quantum solace, quantum world, #quantum

Kopenhagener Deutung - eine der mehreren Interpretationen der Quantenmechanik, die in den Schulen und Universitäten so gelehrt wird, als gäbe es keine Alternativen... In diesem Video lernst du die Merkmale der dominierenden Kopenhagener Deutung kennen. Sie wurde hauptsächlich von den Vätern der Quantenmechanik, Niels Bohr und Werner Heisenberg formuliert und basiert auf Wahrscheinlichkeit, die nicht mit der klassischen Wahrscheinlichkeit unseres Alltags vergleichbar ist. Das Ergebnis eines Würfels lässt sich unter der Voraussetzung, dass man alle auf ihn einwirkenden Kräfte kennt, berechnen; während das Verhalten eines Quantenobjekts (z.B. Elektron), sich naturgemäß nicht berechnen lässt. An einem Doppelspalt-Experiment sieht man diese Unvorhersagbarkeit deutlich. Sogar Teilchen sind in der Lage Interferenz am Schirm zu verursachen; vorausgesetzt: sie werden nicht gemessen. Sobald eine Messung stattfindet, verschwindet das Interferenzmuster; weil die Superposition des Quantenobjekts -- laut der Kopenhagener Deutung -- zerstört wird (Kollaps der Wellenfunktion). Ein wichtiger Bestandteil dieser Interpretation neben dem Korrespondenzprinzip, ist auch der Welle-Teilchen-Dualismus. Ein Quantenobjekt, das sich sowohl als ein Teilchen und auch als eine Welle charakterisiert und niemals vorhersagbar ist? Albert Einstein war jedenfalls damit nicht einverstanden, weshalb er mit zwei anderen Physikern das EPR-Paradoxon (Einstein-Podolsky-Rosen-Paradoxon) formulierte und eher das Konzept "Verborgene-Variablen-Theorie" verfolgte. Zu diesem Konzept gehört beispielsweise die Bohmsche Mechanik.

Google Tech Talk January 6, 2011 Presented by Ron Garret. ABSTRACT Richard Feynman once famously quipped that no one understands quantum mechanics, and popular accounts continue to promulgate the view that QM is an intractable mystery (probably because that helps to sell books). QM is certainly unintuitive, but the idea that no one understands it is far from the truth. In fact, QM is no more difficult to understand than relativity. The problem is that the vast majority of popular accounts of QM are simply flat-out wrong. They are based on the so-called Copenhagen interpretation of QM, which has been thoroughly discredited for decades. It turns out that if Copenhagen were true then it would be possible to communicate faster than light, and hence send signals backwards in time. This talk describes an alternative interpretation based on quantum information theory (QIT) which is consistent with current scientific knowledge. It turns out that there is a simple intuition that makes almost all quantum mysteries simply evaporate, and replaces them with an easily understood (albeit strange) insight: measurement and entanglement are the same physical phenomenon, and you don't really exist.

Although Einstein’s Mind was strongly intuitive and imaginative being a practical explorer he transformed all this for logical expectations and risks based on the “Schrödinger’s Cat’s” realistic exclusivity. Although Bohr’s and Heisenberg’s Minds were strongly logically thinkative being Mathematicians they chose for the intuitive uncertainty based on “Schrödinger’s Cat’s” probability of the disintegration of atoms.

This video gives an objective reality to quantum mechanics! Giving us an alternative to the Copenhagen Interpretation explaining reality as a continuum where new quantum particles our continuously being formed. We feel this process as the forward passage of time itself that forms the geometry of spacetime. The quantum wave-particle function that is explained mathematically by Schrödinger's wave equation represents the forward passage of time itself photon by photon or moment by moment. Therefore Heisenberg's Uncertainty Principle is the same uncertainty that we have with any future event and time is the Hidden Variable of quantum physics.

What we know and what we don't know. There are 3 conventional schools of thought on Quantum Mechanics: there is the Orthodox position which is the Copenhagen interpretation of Quantum Physics who use the Schrodinger-Dirac formalisms based on Max Born's Statistical Interpretation of Quantum Mechanics (http://en.wikipedia.org/wiki/Copenhagen_interpretation) Heisenberg's Matrix formalisms were later shown to be mathematically identical to Shrodinger's Hilbert Space (abstract vector spaces with all the properties of function spaces) based mathematics. This school of thought maintains that quantum mechanics can only be understood in this way (from the observation of photons) and we'll never be able to figure out or understand the inner workings of what's really going on inside the atom. This school of thought is content with not knowing where photons come from during drops in energy states, and maintain that this is just the way it is. PERIOD. There is the Agnostic Position, they don't care they just use what works and don't get involved in the debates or philosophies. And then there is the Realist Position which is the one that Einstein and Planck took. Planck maintained that we needed to figure out how his constant was derived from deeper physics, but Heisenberg just rolled with it... Einstein swore till his death bed that this interpretation of quantum physics was wrong, but could never figure out the answer to make everything work. The argument rages on about the deeper physics of what is really going on, and what types of things will be unlocked once we finally do figure it out... Till then...

Interpretation of Quantum Mechanics is still a controversial topic, we still do not have a well-recieved interpretation now.We will dicuss one of the most popular interpretations today, and dicuss several others in the next episode. Copenhagen Interpretation is a kind of anti-realism interpretation, they believe that dynamical variables does not make sense before measurement. Measurement is not an activity that brought out the value of the dynamical variable that has objectively existed before, it is rather an activity that produce the dynamical variables.

This is a talk I gave at the Quantum Theory: Reconsideration of Foundations 6 Conference in Vaxjo, Sweden on June 12th, 2012. It summarizes a framework based on some original ideas for making sense out of the mathematical formalism of quantum mechanics, and provides an interpretation that is closest in spirit to the Copenhagen Interpretation, except that it provides answers to several "why" questions which that interpretation leaves unresolved. I hope you will find this framework interesting. A few clarifications on specific ideas I tried to convey in my talk but now think didn't do very well: 9:42 I meant to simply state this: in order for two time dimensions to be distinct, they must be orthogonal because from special relativity we know that non-orthogonal time dimensions cannot be distinguished. 11:51 When I said" What happens when the period is longer than tau_a" I misspoke. tau_A is proportional to the period no matter how long. What I meant to say was, "what happens if we consider time intervals that are longer than the period." 12:34 the "geometric set up" I refer to is just this: Two orthogonal time dimensions, one of which is finite and therefore "shorter" than the other (which keeps on increasing), and which are compared indirectly by means of the periodic rotation of the amplitude in the abstract plane formed by them. 13:02 the part I skipped was going to show why the postulated mechanism for indirectly comparing the two time dimensions can be considered a "symmetry": the mechanism is invariant under time reversal because the rotation of the amplitude must go both forward and backward 'simultaneously'. This is required in order to avoid for the indirect comparison to become a net transformation between the time dimensions (A net transformation would imply that the time dimensions are no longer orthogonal, and therefore no longer distinct. This claim follows directly from the fact that in Special Relativity there are two time parameters, proper time and coordinate time, which are related to each other by the Lorentz factor, gamma. One way to think of gamma inverse is that it tells us how much of coordinate time is "projected" onto coordinate time: If 1/gamma is 1 (i.e. observer is at rest relative to what he is observing) all of it is, and if 1/gamma is zero, none of it is projected, which is to say, in that case only the two time parameters cannot be expressed in terms of each other. This is exactly like the orthogonality between vectors). But that means each phase factor derived from this mechanism is only associated with one factor of the product of two factors which represents all possible spacetime manifestations of the areatime object (since addition in the exponent, representing the 'superposition of 2 rotations', corresponds to multiplying their factors together). Thus, the wave function, which is only associated with one of the two complex conjugate phase factors, is also associated only with what is in some sense a "square root" of all possible spacetime manifestations. To obtain the representation of all possible spacetime manifestations, one must take its absolute square, which in this context amounts to placing the two rotations 'on top' of each other. When the to rotations are 'on top' of each other, this becomes just the identity transformation (mathematically the product of two complex conjugate phases), which preserves the distinctness of the two time dimensions, as required. 22:56 Here I don't think I emphasized enough what I was trying to point out: If one conceives of the worldlines of the path integral as "actual" worldlines, then there is problem with special relativity which to my knowledge has not been pointed out before: the spacetime events which correspond to the termination of the worldlines leading up to those regions where the probability amplitude to find a particle vanishes become frame-dependent. But according to special relativity only the order of (spacelike separated) events can depend on an observer frame, not whether they actually occur or not. On the other hand, considering the worldlines of the path integral as actualizable worldlines avoids this problem altogether: Since they are not actual spacetime objects, their termination is not a spacetime event. The only spacetime events are the actual "measurements" of the particles, and the occurrence of these is definitely not frame-dependent. Further and more detailed information on this framework, can be found at deep blue, the University of Michigan's repository: http://deepblue.lib.umich.edu/handle/2027.42/13913/browse?type=author&order=ASC&rpp=20&value=Nikkhah+Shirazi%2C+Armin Also, see http://fqxi.org/community/forum/topic/2474 (Imagination and the Unreasonable Effectiveness of Mathematics: A Case Study in Quantum Mechanics) I appreciate any constructive feedback.

Part of the "Debunking quantum mind" series. This video looks at the "Copenhagen Interpretation". n.b althought there are many different views within Copenhagen this video focuses on Heisenberg's interpretation. i.e. "Whatever Heisenberg's motivation, his invention of a unitary Copenhagen view on interpretation, at the center of which was his own, distinctively subjectivist view of the role of the observer, quickly found an audience." - Found Here http://plato.stanford.edu/entries/qm-copenhagen/ http://en.wikipedia.org/wiki/Copenhagen_interpretation#cite_note-1 Shrodinger's Cat http://en.wikipedia.org/wiki/Shrodingers_cat Berkeley: http://en.wikipedia.org/wiki/Idealism#George_Berkeley Buy this book! http://www.amazon.com/Search-Schr%C3%B6dingers-Cat-Quantum-Physics/dp/0553342533

For those of you in New York City you can check out Matt live at PBS Nerd Night at the NYC YouTube Space on Thursday night September 22nd. Hope to see you there. to.pbs.org/nerdnight Albert Einstein strongly disagreed with Niels Bohr when it came to Bohr’s interpretation of quantum mechanics. Quantum entanglement settled the argument once and for all.

Bohr believed that in observing such particles we collapsed a wave function of probabilities. He asserted that it is only when these wave functions collapse that one of many probabilities is chosen and the particles take on distinct values. Quantum entanglement, John Stewart Bell and Alain Aspect eventually proved that Bohr was correct.

Ruth Kastner, PhD, is a philosopher exploring the foundations of physics. She is on the faculty of the physics department at the State University of New York at Albany. She is also a research associate at the University of Maryland. She is author of The Transactional Interpretation of Quantum Mechanics: The Reality of Possibility and also Understanding Our Unseen World: Solving Quantum Riddles. Here she points out that there are several interpretations of quantum mechanics that are very different from each other. She notes that there are many disagreements about the interpretation of the interpretations. She reviews the perspectives of great physicists such as Neils Bohr, Max Born, Ludwig Boltzmann, and David Bohm. She briefly describes the lesser known “transactional interpretation”. Then she focuses on the philosophical status of the crucial distinction between empirical and sub-empirical reality. New Thinking Allowed host, Jeffrey Mishlove, PhD, is author of The Roots of Consciousness, Psi Development Systems, and The PK Man. Between 1986 and 2002 he hosted and co-produced the original Thinking Allowed public television series. He is the recipient of the only doctoral diploma in "parapsychology" ever awarded by an accredited university (University of California, Berkeley, 1980). He is a past vice-president of the Association for Humanistic Psychology; and is the recipient of the Pathfinder Award from that Association for his contributions to the field of human consciousness. He is also past-president of the non-profit Intuition Network, an organization dedicated to creating a world in which all people are encouraged to cultivate and apply their inner, intuitive abilities.

apologies, i meant the copenhagen interpretation, NOT the compton eff ect --- u get the same type of people everywhere globally. btw side window deflectors good to shade face from harmful light radiation, the side not covered has worse eye vision. "certainity/uncertainity" doesn't exist
Video about the interactions between the observer and electons, the observer can change the behaviour of the electrons, this experiment results could change our wiew of the universe and our relationship with the matter, can we shape it? I recommend two book in particular: - The Olographic Universe by Michael Talbot - The Tao of Physics by Fritjof Capra
