A Brief History of Yippee-Ki-Yay Twenty-five years ago this week, the action movie Die Hard opened and Bruce Willis uttered that famous line. But where does the yippee-ki-yay part come from? (If you’re more interested in the origins of the second half of that saying, check out this article from Slate.) Let’s break it down. The yip part of yippee is old. It originated in the 15th century and meant “to cheep, as a young bird,” according to the Oxford English Dictionary (OED).
Researchers discover quantum algorithm that could improve stealth fighter design (Phys.org) —Researchers at the Johns Hopkins University Applied Physics Laboratory (APL) have devised a quantum algorithm for solving big linear systems of equations. Furthermore, they say the algorithm could be used to calculate complex measurements such as radar cross sections, an ability integral to the development of radar stealth technology, among many other applications. Their research is reported in the June 18 issue of Physical Review Letters.
A world first! Success at complete quantum teleportation Furusawa group at the University of Tokyo has succeeded in demonstrating complete quantum teleportation of photonic quantum bits by a hybrid technique for the first time worldwide. In 1997, quantum teleportation of photonic quantum bits was achieved by a research team at Innsbruck University in Austria. However, such quantum teleportation couldn't be used for information processing, because measurement was required after transport, and the transport efficiency was low. So, quantum teleportation was still a long way from practical use in quantum communication and quantum computing. Anyon In physics, an anyon is a type of quasiparticle that occurs only in two-dimensional systems, with properties much less restricted than fermions and bosons; the operation of exchanging two identical particles may cause a global phase shift but cannot affect observables. Anyons are generally classified as abelian or non-abelian. Abelian anyons have been detected and play a major role in the fractional quantum Hall effect. Non-abelian anyons have not been definitively detected although this is an active area of research. Abelian anyons In space of three or more dimensions, elementary particles are either fermions or bosons, according to their statistical behaviour.
9 Strange Sounds No One Can Explain Everyone has a favorite Wikipedia rabbit hole. Mine is “List of Unexplained Sounds.” I can’t remember how I first made my way to the page, but its array of sonic mysteries has shown me that while space is incredible, our planet is its own frontier of intrigue and unexplainable phenomena. 1. Physicists Discover the Secret of Quantum Remote Control Teleportation is one of the more extraordinary phenomena in the quantum world. It allows a quantum object, such as a photon or electron, to travel from one location to another without passing through the space in between. Teleportation is a standard procedure in any decent quantum mechanics laboratory.
Nasa buys into 'quantum' computer A $15m computer that uses "quantum physics" effects to boost its speed is to be installed at a Nasa facility. It will be shared by Google, Nasa, and other scientists, providing access to a machine said to be up to 3,600 times faster than conventional computers. Unlike standard machines, the D-Wave Two processor appears to make use of an effect called quantum tunnelling. This allows it to reach solutions to certain types of mathematical problems in fractions of a second. Effectively, it can try all possible solutions at the same time and then select the best. Fractional quantum Hall effect The fractional quantum Hall effect (FQHE) is a physical phenomenon in which the Hall conductance of 2D electrons shows precisely quantised plateaus at fractional values of . It is a property of a collective state in which electrons bind magnetic flux lines to make new quasiparticles, and excitations have a fractional elementary charge and possibly also fractional statistics. The 1998 Nobel Prize in Physics was awarded to Robert Laughlin, Horst Störmer and Daniel Tsui for the discovery and explanation of the fractional Hall effect. However, Laughlin's explanation was a phenomenological guess and only applies to fillings where is an odd integer.
List of unexplained sounds The following is a list of sounds, the sources of which remain unknown: NOAA (unidentified) The following unidentified sounds were detected by the USA National Oceanic and Atmospheric Administration using its Equatorial Pacific Ocean autonomous hydrophone array. 'Uncrackable' codes set for step up 4 September 2013Last updated at 13:09 ET By Melissa Hogenboom Science reporter, BBC News Quantum cryptography is a way to share secret digital keys A system that allows electronic messages to be sent with complete secrecy could be on the verge of expanding beyond niche applications. A team of British scientists has discovered a way to build communications networks with quantum cryptography at a larger scale than ever before.
Approaching the Quantum Computing Evolutionary Threshold “Back in 2007, a company called D-Wave made waves by claiming it had built a 16-bit quantum computer at a time when most academic labs could only manage a handful of bits. What they demonstrated, however, wasn’t a quantum computer in the sense that most people use the term. The company has since started calling its device a ‘quantum optimizer.’ Although it’s not a general-purpose quantum computer, the hardware does seem to be capable of tackling some computationally hard challenges. The actual performance of the hardware and the software that controls it (called, somewhat ironically, the Black Box) hasn’t really been described in detail.
Magnetic field Magnetic field of an ideal cylindrical magnet with its axis of symmetry inside the image plane. The magnetic field is represented by magnetic field lines, which show the direction of the field at different points. In everyday life, magnetic fields are most often encountered as an invisible force created by permanent magnets which pull on ferromagnetic materials such as iron, cobalt or nickel and attract or repel other magnets. Magnetic fields are very widely used throughout modern technology, particularly in electrical engineering and electromechanics. The Earth produces its own magnetic field, which is important in navigation. 25 GIFs of Dogs Who Failed Super Hard in 2014 (But We Love Them Anyway) Puppies and Gentledawgs, it’s that time of the year when we do round ups of schtuff. Everyone wagged, everyone wiggled and all in all twas a pretty good year. However, these dogs might beg to differ.
