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.

String theory landscape The string theory landscape refers to the huge number of possible false vacua in string theory.[1] The large number of theoretically allowed configurations has prompted suggestions that certain physical mysteries, particularly relating to the fine-tuning of constants like the cosmological constant or the Higgs boson mass, may be explained not by a physical mechanism but by assuming that many different vacua are physically realized.[2] The anthropic landscape thus refers to the collection of those portions of the landscape that are suitable for supporting intelligent life, an application of the anthropic principle that selects a subset of the otherwise possible configurations. Anthropic principle[edit] Bayesian probability[edit] Some physicists, starting with Weinberg, have proposed that Bayesian probability can be used to compute probability distributions for fundamental physical parameters, where the probability

Gifted Adults Personal GrowthGifted Adults Have people ever called you "too intense" or perhaps "too driven"? Or maybe people have said "Why don't you slow down?" or "Can't you do just one thing?" Do you have a habit of starting a new book to read before you have finished the old one? Executive Success Programs Nancy Salzman Nancy Salzman has over 25 years of intensive study and practice in the fields of healthcare, human potential, and human empowerment. Fueled by a strong desire to help people, Ms. Salzman began her career as a psychiatric nurse. After sustaining a back injury early in her career, she pursued an interest in the fields of chronic pain and chronic illness and began an exploration into non-traditional approaches to health and healing. She studied psycho-neuroimmunology and psychobiology and later studied Ericksonian approaches to brief, solution-based therapy all over the United States and Canada with many acknowledged experts. She then practiced individual and family therapy for seven years before expanding to the field of human potential.

Physics Flash Animations We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing. Also included is the minimum version of the Flash player that is required; the player is available free from The categories are: In addition, I have prepared a small tutorial in using Flash to do Physics animations. Dangerous Minds In an article published yesterday on Alternet with the title “Growing Numbers of Pot Smokers Eat Mango Before Lighting Up,” Clarissa A. León reports about a new trend, if that’s the right word, or perhaps “a growing awareness” is a better way of putting it, among cannabis users that the myrcene molecules found in a mango can “boost” the high, both prolonging and intensifying pot’s euphoric effects. Myrcene is responsible for the aromas of apricots, walnuts and Valencia oranges and is widely used in the perfume industry. It gets its name from the plant mercia and is also found in lemongrass, verbena, hops and the West Indian bay tree used to make bay rum. Its aroma is much like cannabis as it can be woodsy, citrusy and fruity. But one of its lesser-known qualities is that the myrcene allows THC to pass through the blood brain barrier much faster.

Holographic principle In a larger sense, the theory suggests that the entire universe can be seen as a two-dimensional information structure "painted" on the cosmological horizon[clarification needed], such that the three dimensions we observe are an effective description only at macroscopic scales and at low energies. Cosmological holography has not been made mathematically precise, partly because the particle horizon has a finite area and grows with time.[4][5] The holographic principle was inspired by black hole thermodynamics, which conjectures that the maximal entropy in any region scales with the radius squared, and not cubed as might be expected. In the case of a black hole, the insight was that the informational content of all the objects that have fallen into the hole might be entirely contained in surface fluctuations of the event horizon.

The Creative Power of Thinking Outside Yourself New research suggests we generate more creative ideas for other people than for ourselves. The hackneyed expression “thinking outside the box” is thought to come from the puzzle below. The idea is to try and join up all the dots using four straight lines or fewer without taking your pen off the paper or tracing over the same line twice. The ‘box’ that the expression refers to is the implicit one formed in your mind by the dots. To get the solution you have to ignore this implicit box: you have to, as it were, think outside it.

Image evolution What is this? A simulated annealing like optimization algorithm, a reimplementation of Roger Alsing's excellent idea. The goal is to get an image represented as a collection of overlapping polygons of various colors and transparencies. We start from random 50 polygons that are invisible. In each optimization step we randomly modify one parameter (like color components or polygon vertices) and check whether such new variant looks more like the original image. Simulated reality Simulated reality is the hypothesis that reality could be simulated—for example by computer simulation—to a degree indistinguishable from "true" reality. It could contain conscious minds which may or may not be fully aware that they are living inside a simulation. This is quite different from the current, technologically achievable concept of virtual reality. Virtual reality is easily distinguished from the experience of actuality; participants are never in doubt about the nature of what they experience. Simulated reality, by contrast, would be hard or impossible to separate from "true" reality. There has been much debate over this topic, ranging from philosophical discourse to practical applications in computing.

Triple Nine Society The Triple Nine Society (TNS), founded in 1978, is a 501(c)(7) non-profit voluntary association of adults who have scored at or above the 99.9th percentile on specific IQ tests (or similar) under supervised conditions, which generally corresponds to an IQ of 149 or greater using a standard deviation of 16 (e.g. Stanford-Binet IV) and 146 or greater with a standard deviation of 15 (e.g. WAIS-IV, Stanford-Binet 5).[1] This compares with Mensa International, the better-known and larger membership high IQ society which admits applicants who score at or above the 98th percentile, which generally corresponds with an IQ score of 131 (SD 15) or 133 (SD 16), or greater. As of mid-March 2015, TNS reported over 1,500 members residing in more than 40 countries, with most members residing in the United States and Europe.[2] TNS publishes a journal entitled Vidya which contains articles, poetry and other creative content contributed by members conversant with a variety of subjects.

Copenhagen interpretation The Copenhagen interpretation is one of the earliest and most commonly taught interpretations of quantum mechanics.[1] It holds that quantum mechanics does not yield a description of an objective reality but deals only with probabilities of observing, or measuring, various aspects of energy quanta, entities that fit neither the classical idea of particles nor the classical idea of waves. The act of measurement causes the set of probabilities to immediately and randomly assume only one of the possible values. This feature of mathematics is known as wavefunction collapse. The essential concepts of the interpretation were devised by Niels Bohr, Werner Heisenberg and others in the years 1924–27. According to John Cramer, "Despite an extensive literature which refers to, discusses, and criticizes the Copenhagen interpretation of quantum mechanics, nowhere does there seem to be any concise statement which defines the full Copenhagen interpretation
