Planck constant

Planck constant
Plaque at the Humboldt University of Berlin: "Max Planck, discoverer of the elementary quantum of action h, taught in this building from 1889 to 1928." In 1905 the value (E), the energy of a charged atomic oscillator, was theoretically associated with the energy of the electromagnetic wave itself, representing the minimum amount of energy required to form an electromagnetic field (a "quantum"). Further investigation of quanta revealed behaviour associated with an independent unit ("particle") as opposed to an electromagnetic wave and was eventually given the term photon. The Planck relation now describes the energy of each photon in terms of the photon's frequency. This energy is extremely small in terms of ordinary experience. Since the frequency , wavelength λ, and speed of light c are related by λν = c, the Planck relation for a photon can also be expressed as The above equation leads to another relationship involving the Planck constant.

Second death The second death is an eschatological concept in Judaism and Christianity related to punishment after a first, natural, death. Judaism[edit] Although the term is not found in the Hebrew Bible, Sysling in his study (1996) of Teḥiyyat ha-metim (Hebrew; "resurrection of the dead") in the Palestinian Targums identifies a consistent usage of the term "second death" in texts of the Second Temple period and early Rabbinical writings. Quantum spacetime In mathematical physics, the concept of quantum spacetime is a generalization of the usual concept of spacetime in which some variables that ordinarily commute are assumed not to commute and form a different Lie algebra. The choice of that algebra still varies from theory to theory. As a result of this change some variables that are usually continuous may become discrete.

Quantum Physics Revealed As Non-Mysterious This is one of several shortened indices into the Quantum Physics Sequence. Hello! You may have been directed to this page because you said something along the lines of "Quantum physics shows that reality doesn't exist apart from our observation of it," or "Science has disproved the idea of an objective reality," or even just "Quantum physics is one of the great mysteries of modern science; no one understands how it works." Old Earth creationism Old Earth creationism is an umbrella term for a number of types of creationism, including gap creationism, progressive creationism, and evolutionary creationism.[1] Old Earth creationism is typically more compatible with mainstream scientific thought on the issues of physics, chemistry, geology and the age of the Earth, in comparison to young Earth creationism.[2] Types of old Earth creationism[edit] Gap creationism[edit] Gap creationism states that life was immediately and recently created on a pre-existing old Earth. One variant rests on a rendering of Genesis 1:1-2 as: "In the beginning ... the earth was formless and void."

Quantum entanglement Quantum entanglement is a physical phenomenon that occurs when pairs or groups of particles are generated or interact in ways such that the quantum state of each particle cannot be described independently – instead, a quantum state may be given for the system as a whole. Such phenomena were the subject of a 1935 paper by Albert Einstein, Boris Podolsky and Nathan Rosen,[1] describing what came to be known as the EPR paradox, and several papers by Erwin Schrödinger shortly thereafter.[2][3] Einstein and others considered such behavior to be impossible, as it violated the local realist view of causality (Einstein referred to it as "spooky action at a distance"),[4] and argued that the accepted formulation of quantum mechanics must therefore be incomplete. History[edit] However, they did not coin the word entanglement, nor did they generalize the special properties of the state they considered.

NASA to Launch Spacecraft to Keep Track of Global Carbon Dioxide - SciTech Daily NASA is about to launch the Orbiting Carbon Observatory – a satellite dedicated to the study of global carbon dioxide sources that will help researchers predict the future of climate change. In the lexicon of climate change, one word appears more often than any other: “carbon.” Carbon credits, carbon emissions, carbon sequestration…. These terms are on everyone’s lips. Young Earth creationism Young Earth Creationism (YEC) is the religious belief[1] that the Universe, Earth and all life on Earth were created by direct acts of the Abrahamic God during a relatively short period, between 5,700 and 10,000 years ago.[2] Its primary adherents are those Christians and Jews[3] who, using a literal interpretation of the Genesis creation narrative as a basis, believe that God created the Earth in six 24-hour days.[4][5] Young Earth Creationists differ from other creationists in that they believe in a strict-literal interpretation of the Bible regarding the age of the Earth. This contrasts with Old Earth Creationists, who believe that the Book of Genesis may be interpreted metaphorically and who accept the scientifically determined age of Earth and the universe.[6] Since the mid-20th century, young Earth Creationists starting with Henry M.

Efimov state The Efimov effect is an effect in the quantum mechanics of Few-body systems predicted by the Russian theoretical physicist V. N. Efimov[1][2] in 1970. New NASA/NOAA Animations Reveal Water Vapor Over Oceans - SciTech Daily The movement of upper-air water vapor over the Eastern Pacific is shown using GOES satellite air temperature data. High, cold clouds are white. High, cold, clear air (around -28 F) is blue. Lower, warmer, dry air (around -10 F) is magenta (where clear, dry air penetrates lower in the atmosphere).

Creation of man from clay Fashioning a man out of clay According to Genesis 2:7 "And the Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul."According to the Qur'an[23:12–15], God created man from clay.According to greek mythology (see Hesiod's poem Theogeny), Prometheus created man from clay, while Athena breathed life into them.According to Chinese mythology (see Chu Ci and Imperial Readings of the Taiping Era), Nüwa molded figures from the yellow earth, giving them life and the ability to bear children.According to Egyptian mythology the god Khnum creates human children from clay before placing them into their mother's womb. انا خلقنا الانسان من صلصال من حمإ مسنون reference from sour at alhijer holy Quran

Amplituhedron An amplituhedron is a geometric structure that enables simplified calculation of particle interactions in some quantum field theories. In planar N = 4 supersymmetric Yang–Mills theory, an amplituhedron is defined as a mathematical space known as the positive Grassmannian. The connection between the amplituhedron and scattering amplitudes is at present a conjecture that has passed many non-trivial checks, including an understanding of how locality and unitarity arise as consequences of positivity. Research has been led by Nima Arkani-Hamed. Edward Witten described the work as “very unexpected" and said that "it is difficult to guess what will happen or what the lessons will turn out to be.

Research Reveals New Man-Made Ozone-Depleting Gases in the Atmosphere - SciTech Daily False-color view of total ozone over the Antarctic pole. The purple and blue colors are where there is the least ozone, and the yellows and reds are where there is more ozone. Credit: NASA New research from scientists at the University of East Anglia reveals four new man-made gases in the atmosphere that are contributing to the destruction of the ozone layer. New research published in the journal Nature Geoscience reveals that more than 74,000 tonnes of three new chlorofluorocarbons (CFCs) and one new hydrochlorofluorocarbon (HCFC) have been released into the atmosphere. Scientists made the discovery by comparing today’s air samples with air trapped in polar firn snow – which provides a century-old natural archive of the atmosphere.

Intelligent design Intelligent design (ID) is the pseudoscientific view[1][2] that "certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection."[3] Educators, philosophers, and the scientific community have demonstrated that ID is a religious argument, a form of creationism which lacks empirical support and offers no tenable hypotheses.[4][5][6] Proponents argue that it is "an evidence-based scientific theory about life's origins" that challenges the methodological naturalism inherent in modern science,[7][8] while conceding that they have yet to produce a scientific theory.[9] The leading proponents of ID are associated with the Discovery Institute, a politically conservative think tank based in the United States.[n 1] Although they state that ID is not creationism and deliberately avoid assigning a personality to the designer, many of these proponents express belief that the designer is the Christian deity.[n 2]
