Uncertainty principle where ħ is the reduced Planck constant. The original heuristic argument that such a limit should exist was given by Heisenberg, after whom it is sometimes named the Heisenberg principle. This ascribes the uncertainty in the measurable quantities to the jolt-like disturbance triggered by the act of observation. Though widely repeated in textbooks, this physical argument is now known to be fundamentally misleading. While the act of measurement does lead to uncertainty, the loss of precision is less than that predicted by Heisenberg's argument; the formal mathematical result remains valid, however. Since the uncertainty principle is such a basic result in quantum mechanics, typical experiments in quantum mechanics routinely observe aspects of it. Certain experiments, however, may deliberately test a particular form of the uncertainty principle as part of their main research program.
Golden Ratio Discovered in the Quantum World By Rakefet TavorEpoch Times Staff Created: January 19, 2010 Last Updated: June 17, 2012 PICTURING THE GOLDEN RATIO: Scientists fired neutrons at cobalt niobate particles, finding resonant notes with the golden ratio. (Tennant/HZB) The “golden ratio,” which is equal to approximately 1.618, can be found in various aspects of our life, including biology, architecture, and the arts. But only recently was it discovered that this special ratio is also reflected in nanoscale, thanks to researchers from the U.K.’s Oxford University, University of Bristol, and Rutherford Appleton Laboratory, and Germany’s Helmholtz-Zentrum Berlin for Materials and Energy (HZB).
In Spring it is the Dawn: 'A Wild Sheep Chase' Discussion (JLit Book Group) Welcome to the Japanese Literature Book Group discussion of A Wild Sheep Chase by Haruki Murakami. About the author Haruki Murakami was born in Kyoto, Japan, in 1949. He grew up in Kobe and graduated from Waseda University in Tokyo. Fermat's Last Theorem The 1670 edition of Diophantus' Arithmetica includes Fermat's commentary, particularly his "Last Theorem" (Observatio Domini Petri de Fermat). In number theory, Fermat's Last Theorem (sometimes called Fermat's conjecture, especially in older texts) states that no three positive integers a, b, and c can satisfy the equation an + bn = cn for any integer value of n greater than two. This theorem was first conjectured by Pierre de Fermat in 1637 in the margin of a copy of Arithmetica where he claimed he had a proof that was too large to fit in the margin. The first successful proof was released in 1994 by Andrew Wiles, and formally published in 1995, after 358 years of effort by mathematicians. The unsolved problem stimulated the development of algebraic number theory in the 19th century and the proof of the modularity theorem in the 20th century.
Golden ratio Line segments in the golden ratio In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities. The figure on the right illustrates the geometric relationship. Expressed algebraically, for quantities a and b with a > b > 0, The golden ratio is also called the golden section (Latin: sectio aurea) or golden mean. Other names include extreme and mean ratio, medial section, divine proportion, divine section (Latin: sectio divina), golden proportion, golden cut, and golden number. Some twentieth-century artists and architects, including Le Corbusier and Dalí, have proportioned their works to approximate the golden ratio—especially in the form of the golden rectangle, in which the ratio of the longer side to the shorter is the golden ratio—believing this proportion to be aesthetically pleasing (see Applications and observations below).
Philosophy of mind A phrenological mapping of the brain – phrenology was among the first attempts to correlate mental functions with specific parts of the brain Philosophy of mind is a branch of philosophy that studies the nature of the mind, mental events, mental functions, mental properties, consciousness, and their relationship to the physical body, particularly the brain. The mind–body problem, i.e. the relationship of the mind to the body, is commonly seen as one key issue in philosophy of mind, although there are other issues concerning the nature of the mind that do not involve its relation to the physical body, such as how consciousness is possible and the nature of particular mental states.
How to Make Anything Signify Anything Detail from a photograph of World War I cryptographers trained by William and Elizebeth Friedman, Aurora, Illinois, early 1918. By facing either forward or sideways, the soldiers formed a coded phrase utilizing Francis Bacon’s biliteral cipher. The intended message was the Baconian motto “Knowledge is power,” but there were insufficient people to complete the r (and the w was compromised by one soldier looking the wrong way).Included as a pull-out poster in issue 40, Knowledge Is Powe is also available for purchase in an unfolded version suitable for framing.
Can Mushrooms Be The New Plastic? Today, plastics are among the most toxic and polluting substances we use on a daily basis. Simply focusing on styrofoam alone, it is a $20+ billion industry who’s products are found in anything from TV protective packaging to disposable coffee cups. The trouble with all of this styrofoam is that it cannot be recycled or disposed of. Once created, it stays on the planet for thousands and thousands of years. Styrofoam is petroleum based and contains a carcinogenic and neutroxic chemical called Benzene. In 1986, the Environment Protection Agency National Human Adipose Tissue Survey identified styrene residues in every single sample of human fat tissue they studied, all of which were complied in 1982 within the US. This was the first time it was recognized that styrene from food and other packaging could find its way into the human body. Simply put, styrofoam is not only poisoning our environment but also our bodies due to its highly toxic nature.
Reductionism Descartes held that non-human animals could be reductively explained as automata — De homine, 1662. Reductionism strongly reflects a certain perspective on causality. In a reductionist framework, the phenomena that can be explained completely in terms of relations between other more fundamental phenomena, are called epiphenomena. Often there is an implication that the epiphenomenon exerts no causal agency on the fundamental phenomena that explain it. Reductionism does not preclude the existence of what might be called emergent phenomena, but it does imply the ability to understand those phenomena completely in terms of the processes from which they are composed. This reductionist understanding is very different from that usually implied by the term 'emergence', which typically intends that what emerges is more than the sum of the processes from which it emerges.

NASA-backed fusion engine could cut Mars trip down to 30 days High performance access to file storage NASA, and plenty of private individuals, want to put mankind on Mars. Now a team at the University of Washington, with funding from the space agency, is about to start building a fusion engine that could get humans there in just 30 days and make other forms of space travel obsolete.
