Von Neumann entropy In quantum statistical mechanics, the von Neumann entropy, named after John von Neumann, is the extension of classical Gibbs entropy concepts to the field of quantum mechanics. For a quantum-mechanical system described by a density matrix ρ, the von Neumann entropy is then the von Neumann entropy is merely In this form, S can be seen to amount to the information theory Shannon entropy. Background John von Neumann rigorously established the mathematical framework for quantum mechanics in his work Mathematical Foundations of Quantum Mechanics−−Mathematische Grundlagen der Quantenmechanik. In it, he provided a theory of measurement, where the usual notion of wave-function collapse is described as an irreversible process (the so-called von Neumann or projective measurement).
Invisible Worlds Richard Hammond's Invisible Worlds is a BBC television documentary programme presented by Richard Hammond that features state-of-the-art camera technology used to focus on what humans cannot see with the naked eye. It is one series long consisting of three episodes. 1. The Beauty of Diagrams Series in which mathematician Marcus du Sautoy explores the stories behind some of the most familiar scientific diagrams. Vitruvian Man - He looks at Leonardo da Vinci's world-famous diagram of the perfect human body, which has many layers from anatomy to architecture, and defines our species like no other drawing before or since. The Vitruvian Man, drawn in the 1480s when he was living and working in Milan, has become one of the most famous images in the world. Leonardo's drawings form a vast body of work, covering every imaginable subject in spectacular detail: from feet, skulls and hands to muscles and sinews; from hearts and lungs to buildings, bridges and flying machines.
Athene’s Theory of Everything Bachir "Chiren" Boumaaza, aka Athene, is an extravagant Internet celebrity, with over 240 million upload views, and a professional gamer. If you haven't heard of him, he's a record holder in World of Warcraft and online poker, and plays the main character in a series of videos on a popular YouTube channel with well over 340,000 subscribers. Athene is known for crashing gaming servers, with the aid of his massive army of followers, who just love to be part of the controversy and trouble Athene is so well known for. Over the past year, we haven't heard much from him, and it seemed as though he had fallen off the grid. Recently Chiren broke his silence, and announced that his disappearance was due to being very busy, conducting new research in the fields of quantum mechanics, general and special relativity, and neuroscience. (WTF!!!)
Google: Behind the Screen What if all the information in the world was categorized and easily searchable? What if all the news from around the world, all books, written texts, photos and videos that exist on a place in the world would be collected, and would be available everywhere? That is precisely the goal of Google and it will not be long for it to be realized. Through the well-known search engine, Google Earth, where all information is classified by geographical location, along with Google Books, a project where Google digitizes complete libraries.
Secrets of the Occult Secrets of the Occult explores the world of the occult from the ancient and modern magicians who practice it to the cutting edge scientists attempting to explain its mysterious claims. This program highlights the advances that have been achieved by innovators who challenged established reality like Newton, Galileo, Carl Jung and Einstein. The claims of the occult magicians are put under the microscope to reveal the fascinating interface between ancient Egyptian and Greek beliefs to modern discoveries of the mind and the physical world. The Magicians & The Scientists Secrets of the Occult DVD Extras explores the fascinating interface between occult beliefs and modern discoveries of the mind and the physical world. Experts speak on a range of topics from the function of magic to the beginning of mysticism. The Magicians
Body Hyperspace Introduction. The article that follows this introduction featured in the science section of the 25th December 1999 edition of The Economist magazine. It gives a good idea of how hyperspace is treated in mainstream, leading edge physics. Hyperspace poses something of a dilemma for modern physics. The Search for Life: The Drake Equation For many years our place in the universe was the subject of theologians and philosophers, not scientists, but in 1960 one man changed all that. Dr Frank Drake was one of the leading lights in the new science of radio astronomy when he did something that was not only revolutionary, but could have cost him his career. Working at the National Radio Astronomy Observatory in Greenback in Virginia, he pointed one of their new 25-meter radio telescopes at a star called Tau Ceti twelve light years from earth, hoping for signs of extra-terrestrial intelligence. Although project Ozma resulted in silence, it did result in one of the most seminal equations in the history of science - the Drake Equation - which examined seven key elements necessary for ET intelligence to exist, from the formation of stars to the likely length a given intelligent civilization may survive. However, in the 50 years of listening that has followed, not one single bleep has been heard from ET.
Scientific evidence for survival of consciousness after death According to Wikipedia.org, "psychometry" is a psychic ability in which the user is able to relate details about the past condition of an object or area, usually by being in close contact with it. The user could allegedly, for example, give police precise details about a murder or other violent crime if they were at the crime scene or were holding the weapon used. About.com's Paranormal Phenomena website lists information about several of the most convincing psychometrists. Stefan Ossowiecki, a Russian-born psychic, is one of the most famous psychometrists. Ossowiecki claimed to be able to see people's auras and to move objects through psychokinesis.
Quantum dot Colloidal quantum dots irradiated with a UV light. Different sized quantum dots emit different color light due to quantum confinement. Researchers have studied applications for quantum dots in transistors, solar cells, LEDs, and diode lasers. They have also investigated quantum dots as agents for medical imaging and as possible qubits in quantum computing. Life After People The very notion is deliciously ghoulish: What happens to earth if - or when - people suddenly vanished? The History Channel presents a dramatic, fascinating what-if scenario, part science fiction and part true natural science. Welcome to Earth, Population: 0 is the catchy tagline, Life After People's 94 minutes are so gripping you nearly forget while you watch that you, yourself, will be gone too. It turns out that earth can go along very nicely without us. The hardest part of the special is probably in the first 15 minutes, when pet owners confront what likely will happen to their dogs (thankfully, the show follows those dogs who break out of their houses, and the prognosis for them to survive as scavengers is good). As the fictional days and weeks tick by, the process of nature's reclaiming the planet becomes less grim and more fascinating.
War and Globalization: The Truth Behind 9/11 (Lecture) In this lecture by Michel Chossudovsky, he blows away the smokescreen put up by the mainstream media, that 9/11 was an attack on America by Islamic terrorists. Through meticulous research, he has uncovered a military-intelligence ploy behind the September 11 attacks, and the cover-up and complicity of key members of the Bush Administration. According to Chossudovsky, the war on terrorism is a complete fabrication based on the illusion that one man, Osama bin Laden, outwitted the $40 billion-a-year American intelligence apparatus.
