Steorn
Steorn Ltd () was a small, private technology development company based in Dublin, Ireland. In August 2006, it announced that it had developed a technology to provide "free, clean, and constant energy" via an apparent perpetual motion machine, something which is contrary to the law of conservation of energy, a fundamental principle of physics. Steorn challenged the scientific community to investigate their claim and, in December 2006, said that it had chosen a jury of scientists to do so. In June 2009 the jury gave its unanimous verdict that Steorn had not demonstrated the production of energy. Steorn gave two public demonstrations of their technology. In the first demonstration, in July 2007 at the Kinetica Museum in London, the device failed to work. The second demonstration, which ran from December 2009 to February 2010 at the Waterways Visitor Centre in Dublin, involved a motor powered by a battery and provided no independent evidence that excess energy was being generated. ...

Old Norse Language
Old Norse, Old Nordic, or Old Scandinavian, is a stage of development of North Germanic languages, North Germanic dialects before their final divergence into separate Nordic languages. Old Norse was spoken by inhabitants of Scandinavia and their Viking expansion, overseas settlements and chronologically coincides with the Viking Age, the Christianization of Scandinavia and the consolidation of Scandinavian kingdoms from about the 7th to the 15th centuries. The Proto-Norse language developed into Old Norse by the 8th century, and Old Norse began to develop into the modern North Germanic languages in the mid-to-late 14th century, ending the language phase known as Old Norse. These dates, however, are not absolute, since written Old Norse is found well into the 15th century. Old Norse was divided into three dialects: Old West Norse, ''Old West Norse'' or ''Old West Nordic'' (often referred to as ''Old Norse''), Old East Norse, ''Old East Norse'' or ''Old East Nordic'', and ''Ol ...

Noether's Theorem
Noether's theorem or Noether's first theorem states that every differentiable symmetry of the action of a physical system with conservative forces has a corresponding conservation law. The theorem was proven by mathematician Emmy Noether in 1915 and published in 1918. The action of a physical system is the integral over time of a Lagrangian function, from which the system's behavior can be determined by the principle of least action. This theorem only applies to continuous and smooth symmetries over physical space. Noether's theorem is used in theoretical physics and the calculus of variations. It reveals the fundamental relation between the symmetries of a physical system and the conservation laws. It also made modern theoretical physicists much more focused on symmetries of physical systems. A generalization of the formulations on constants of motion in Lagrangian and Hamiltonian mechanics (developed in 1788 and 1833, respectively), it does not apply to systems that cann ...

Dogma
Dogma is a belief or set of beliefs that is accepted by the members of a group without being questioned or doubted. It may be in the form of an official system of principles or doctrines of a religion, such as Roman Catholicism, Judaism, Islam or Protestantism, as well as the Philosophical theory, positions of a philosopher or of a Philosophical movement, philosophical school such as positivism, postmodernism, egalitarianism, and dark enlightenment. It may also be found in political belief-systems, such as Marxism, communism, capitalism, progressivism, liberalism, conservatism, and fascism. In the pejorative sense, dogma refers to enforced decisions, such as those of aggressive political interests or authorities. More generally, it is applied to some strong belief which its adherents are not willing to discuss rationally. This attitude is named as a dogmatic one, or as dogmatism; and is often used to refer to matters related to religion, but is not limited to theistic attitudes ...

Martin Fleischmann
Martin Fleischmann FRS (29 March 1927 – 3 August 2012) was a British chemist who worked in electrochemistry. By Associated Press. Premature announcement of his cold fusion research with Stanley Pons, regarding excess heat in heavy water, caused a media sensation and elicited skepticism and criticism from many in the scientific community. Personal life Fleischmann was born in Karlovy Vary, Czechoslovakia, in 1927. His father was a wealthy lawyer and his mother the daughter of a high-ranking Austrian civil officer. Since his father was of Jewish heritage, Fleischmann's family moved to the Netherlands, and then to England in 1938, to avoid Nazi persecution. His father died of the complications of injuries received in a Nazi prison, after which Fleischmann lived for a period with his mother in a leased cottage in Rustington, Sussex. His early education was obtained at Worthing High School for Boys. After serving in the Czech Airforce Training Unit during the war, he moved ...

Australian Skeptics
Australian Skeptics is a loose confederation of like-minded organisations across Australia that began in 1980. Australian Skeptics investigate paranormal and pseudoscientific claims using scientific methodologies. This page covers all Australian skeptical groups which are of this mindset. The name "Australian Skeptics" can be confused with one of the more prominent groups, "Australian Skeptics Inc", which is based in Sydney and is one of the central organising groups within Australian Skeptics. Origins In 1979, Mark Plummer (later president of Australian Skeptics) sent a letter to the American skeptical magazine '' The Zetetic'' in which he expressed interest in beginning a skeptical organisation in Australia. Sydney electronics entrepreneur Dick Smith responded to the letter, and offered to sponsor a visit to Australia by James Randi, the principal investigator for the American-based Committee for the Scientific Investigation of Claims of the Paranormal (CSICOP), now known ...

Magnetic Field
A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. A permanent magnet's magnetic field pulls on ferromagnetic materials such as iron, and attracts or repels other magnets. In addition, a nonuniform magnetic field exerts minuscule forces on "nonmagnetic" materials by three other magnetic effects: paramagnetism, diamagnetism, and antiferromagnetism, although these forces are usually so small they can only be detected by laboratory equipment. Magnetic fields surround magnetized materials, and are created by electric currents such as those used in electromagnets, and by electric fields varying in time. Since both strength and direction of a magnetic field may vary with location, it is described mathematically by a function assigning a vector to each point of space, cal ...

JPEG
JPEG ( ) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. Since its introduction in 1992, JPEG has been the most widely used image compression standard in the world, and the most widely used digital image format, with several billion JPEG images produced every day as of 2015. The term "JPEG" is an acronym for the Joint Photographic Experts Group, which created the standard in 1992. JPEG was largely responsible for the proliferation of digital images and digital photos across the Internet, and later social media. JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; along with JPEG ...
