Many-worlds interpretation

Many-worlds interpretation
The quantum-mechanical "Schrödinger's cat" paradox according to the many-worlds interpretation. In this interpretation, every event is a branch point; the cat is both alive and dead, even before the box is opened, but the "alive" and "dead" cats are in different branches of the universe, both of which are equally real, but which do not interact with each other.[1] The many-worlds interpretation is an interpretation of quantum mechanics that asserts the objective reality of the universal wavefunction and denies the actuality of wavefunction collapse. Many-worlds implies that all possible alternate histories and futures are real, each representing an actual "world" (or "universe"). In lay terms, the hypothesis states there is a very large—perhaps infinite[2]—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.

Despite significant academic interest, there is no consensus on its precise nature and consequently a final 'correct' resolution has not yet been established.[1] One approach, offered by the logical school of thought, suggests that the problem arises in a self-contradictory self-referencing statement at the heart of the judge's sentence. Another approach, offered by the epistemological school of thought, suggests the unexpected hanging paradox is an example of an epistemic paradox because it turns on our concept of knowledge.[2] Even though it is apparently simple, the paradox's underlying complexities have even led to it being called a "significant problem" for philosophy.[3] Some authors[who?]

L’apesanteur et ses effets sur l’organisme humain - Article Le corps humain subit de multiples changements physiologiques Peu après avoir quitté l’atmosphère terrestre, l’absence de gravité entraîne une croissance de l’astronaute de l’ordre de deux à trois centimètres. Ce phénomène est dû à l’étirement de la colonne vertébrale, qui n’est plus soumis à l’attraction de la gravité. Ces symptômes auront pour l’essentiel complètement disparu au terme de la première semaine, l’organisme s’adaptant progressivement à ces nouvelles conditions. En contrecoup de tous ces changements physiologiques, les astronautes ont toujours besoin d’un certain temps pour réadapter leur organisme et leurs sens à l’attraction de la gravité de retour sur Terre. Aspects médicaux et physiologiques de l’apesanteur Aujourd’hui, nous avons la preuve que l’être humain peut vivre en apesanteur pendant de longues périodes sans risque sanitaire majeur. Les effets suivants peuvent être observés après un séjour prolongé en apesanteur :

The Ultimate multiverse Hong–Ou–Mandel effect Quantum-mechanical description[edit] Physical description[edit] When a photon enters a beam splitter, there are two possibilities: it will either be reflected or transmitted. The relative probabilities of transmission and reflection are determined by the reflectivity of the beam splitter. Here, we assume a 50:50 beam splitter, in which a photon has equal probability of being reflected and transmitted. Figure 1. Since the state of the beam splitter does not "record" which of the four possibilities actually happens, Feynman's rule dictates that we have to add all four possibilities at the amplitude level. Mathematical description[edit] Consider two optical modes a and b that carry annihilation and creation operators , and . where is a single-photon state. Unitarity of the transformation now means unitarity of the matrix. When two photons enter the beam splitter, one on each side, the state of the two modes becomes Since the commutator of the two creation operators and . Figure 2. by: If

Keith Raniere, Conceptual Founder of Executive Success Programs and NXIVM Quantum tunnelling Quantum mechanical phenomenon In physics, quantum tunnelling, barrier penetration, or simply tunnelling is a quantum mechanical phenomenon in which an object such as an electron or atom passes through a potential energy barrier that, according to classical mechanics, should not be passable due to the object not having sufficient energy to pass or surmount the barrier. Tunneling is a consequence of the wave nature of matter, where the quantum wave function describes the state of a particle or other physical system, and wave equations such as the Schrödinger equation describe their behavior. The probability of transmission of a wave packet through a barrier decreases exponentially with the barrier height, the barrier width, and the tunneling particle's mass, so tunneling is seen most prominently in low-mass particles such as electrons or protons tunneling through microscopically narrow barriers. The effect was predicted in the early 20th century. Introduction to the concept [edit] or where .

Level IV: Ultimate ensemble The Landscape multiverse David Deutsch David Elieser Deutsch, FRS (born 1953 in Haifa, Israel) is a British physicist at the University of Oxford. He is a non-stipendiary Visiting Professor in the Department of Atomic and Laser Physics at the Centre for Quantum Computation (CQC) in the Clarendon Laboratory of the University of Oxford. He pioneered the field of quantum computation by formulating a description for a quantum Turing machine, as well as specifying an algorithm designed to run on a quantum computer.[2] He is a proponent of the many-worlds interpretation of quantum mechanics. Career[edit] In the Royal Society of London's announcement that Deutsch had become a Fellow of the Royal Society (FRS) in 2008, the Society described Deutsch's contributions thus:[3] He is currently working on constructor theory, an attempt at generalizing the quantum theory of computation to cover not just computation but all physical processes.[4] Popular science books[edit] The Fabric of Reality[edit] There are "four strands" to his theory:

Executive Success Programs Think back on your life and all of the things you wanted to do but never did. Perhaps you're achieving your goals and would like to progress faster. What’s stopping you? When you look around, you see people who are living up to their full potential and making their dreams come true. Emotion is the internal force that empowers us to live our lives to the fullest and to achieve the success we desire and deserve. Our programs facilitate this by developing and energizing your emotional foundation. Very often these self-imposed limitations have become so familiar to us that we are not even aware they are there. Our programs employ a unique, patent-pending technology called Rational Inquiry™, which allows you to re-examine and re-incorporate perceptions that may be the foundation of self-imposed limitations. Strengthening your emotional constitution brings about inner breakthroughs that can dramatically raise the level of your performance and achievement.

#87: A Superfast Magnetic Shift | Earth Science Every 200,000 years or so, the earth’s poles trade places. Typically it takes several thousand years. But when geologists Scott Bogue of Occi­dental College and Jonathan Glen of the U.S. Geological Survey examined 15-million-year-old Nevada lava, they found evidence that the planet’s mag­netic field shifted several thousand times faster than normal at least once. When lava cools, it locks away a record of the earth’s magnetic field. Examining lavas that cooled in two consecutive years, Bogue and Glen found the field swung 53 degrees from east to north, about 1 degree a week. Bogue thinks the quick shift took place near the end of a millennia-long polarity reversal, when a slow magnetic drift accelerated dramatically for reasons unexplained. Further study could help geolo­gists understand the turbulent motion of the earth’s liquid core, which generates the magnetic field and may initiate its flips.
