Each wave state has a single discrete spin ( spin up or spin down ).

If denotes the quantum state of a particle ( n ) with momentum p, spin J whose component in the z-direction is σ, then one has

Natural beryllium, save for slight contamination by cosmogenic radioisotopes, is essentially beryllium-9, which has a spin of-3 / 2.

This is totally spurious, since no matter who measured first the other will measure the opposite spin despite the fact that ( in theory ) the other has a 50 % ' probability ' ( 50: 50 chance ) of measuring the same spin, unless data about the first spin measurement has somehow passed faster than light ( of course TI gets around the light speed limit by having information travel backwards in time instead ).

The only known mechanisms for the creation of magnetic dipoles are by current loops or quantum-mechanical spin since the existence of magnetic monopoles has never been experimentally demonstrated.

In state I, the electron has spin pointing upward along the z-axis (+ z ) and the positron has spin pointing downward along the z-axis (− z ).

In state II, the electron has spin − z and the positron has spin + z.

In state Ia, Alice's electron has spin + x and Bob's positron has spin − x.

In state IIa, Alice's electron has spin − x and Bob's positron has spin + x.

( When one considers also their spin component, one speaks of atomic spin orbitals.

It can also be found in Fermi – Dirac statistics ( for particles of half-integer spin ) and Bose – Einstein statistics ( for particles of integer spin ).

If the cord is twisted up tightly on itself and then the bucket is released, it begins to spin rapidly, not only with respect to the experimenter, but also in relation to the water it contains.

Neutrons can also probe atomic length scales and are used to study scattering off nuclei and electron spins and magnetization ( as neutrons themselves have spin but no charge ).

From the above equations, it can be shown that the spin singlet can also be written as

A flying spin can also be performed as part of a spin sequence.

In condensed matter physics, Dyson also did studies in the phase transition of the Ising model in 1 dimension and spin waves.

The spin of the electrons in atoms is the main source of ferromagnetism, although there is also a contribution from the orbital angular momentum of the electron about the nucleus.

The exchange interaction is related to the Pauli exclusion principle, which says that two electrons with the same spin cannot also have the same " position ".

This effect is also explained by special relativity, and it leads to the so-called spin-orbit coupling, i. e., an interaction between the electron's orbital motion around the nucleus, and its spin.

There have also been a few other spin off games such as Quake Mobile in 2005 and Quake Live, an internet browser based modification of Quake III.

It may also resemble a jumping spin roundhouse kick ( developed by James ' Two Screens ' Perkins ) into a spinning hook kick, all in one jump and one spin although the difference is that both legs should remain in the air at the same time for a considerable amount of time.

This kick is also known as a heel kick, reverse turning kick, reverse round kick, spinning hook kick, or spin kick.

Highly skilled leg spin bowlers are also able to bowl deliveries that behave unexpectedly, including the googly, which turns the opposite way to a normal leg break and the topspinner, which doesn't turn but dips sharply and bounces higher than other deliveries.

The left-arm unorthodox spin like a leg break or leg spin is also a bowling action.

They also arise from " intrinsic " magnetic dipoles arising from quantum-mechanical spin.

I. e., not only and must be substituted by α and β, respectively ( the first entity means " spin up ", the second one " spin down "), but also the sign + by the − sign, and finally r < sub > i </ sub > by the discrete values s < sub > i </ sub > (= ± ½ ); thereby we have and.

The Mars Oz reference mission also differs in assuming, based on space station experience, that spin gravity will not be required.

) There are variants of μSR, e. g. muon spin rotation, which is affected by the presence of a magnetic field applied transverse to the muon beam direction ( since muons are typically produced in a spin-polarized state from the decay of pions ), and avoided level crossing ( ALC ), which is also called level crossing resonance ( LCR ).

* Rifled Traditionally, artillery projectiles have been spin-stabilised, meaning that they spin in flight so that gyroscopic forces prevent them from tumbling.

Could this piece then have been commissioned as political spin, a subtle myth or legend to promote his right to be nominated Emperor?

In 2 + 1 dimensions, however, gravity is a topological field theory, and it has been successfully quantized in several different ways, including spin networks.

FitzGerald gave the Rubaiyat a distinct fatalistic spin, although it has been claimed that he softened the impact of Khayyam's nihilism and his preoccupation with the mortality and transience of all things.

This immediately explained the appearance of two-component wave functions in Pauli's phenomenological theory of spin, something that up until then had been regarded as mysterious, even to Pauli himself.

This result was difficult to understand at the time, however, because the neutron had not yet been discovered, and it was thought incorrectly that the < sup > 14 </ sup > N nucleus contains 14 protons and 7 electrons, or an odd number of ( 21 ) particles in total which would correspond to a half-integral spin.

Firstly, it has been suggested that the HTS emerges by antiferromagnetic spin fluctuation in a doped system.

They have been of special interest for the HTS materials because many researchers have wondered whether spin correlations might play a role in the mechanism of the HTS.

The spin from rifling decreases the effective penetration of these rounds ( rifling diverts some of the linear kinetic energy to rotational kinetic energy, thus decreasing the round's velocity and impact energy ) and so they are generally fired from smoothbore guns ; a practice that has been taken up by Israel — a major supplier of " arrow " rounds — China, France, Pakistan, Germany, Russia, and the United States in their tanks.

The elongated body of the spacecraft had been designed to spin about its long ( least-inertia ) axis but refused to do so, and instead started precessing due to energy dissipation from flexible structural elements.

This company has been portrayed as being unethical, manipulative, obsessed with spin, and environmentally unfriendly.

The Thimbletron has been largely retired in public performances in favor of the Wheel of Mashup, in which audience members come up on stage and spin a wheel to randomly select the music and vocals to be combined.

Young was there with The Squires, a Winnipeg group he had been leading since February 1963, and Stills was on tour with The Company, a spin off from the Au Go Go Singers.

In mathematics, spin networks have been used to study skein modules and character varieties, which correspond to spaces of connections.

It was called " anomalous " because the electron spin had not yet been discovered, and so there was no good explanation for it at the time that Zeeman observed the effect.

As electrons and holes are fermions with half integer spin, an exciton may either be in a singlet state or a triplet state depending on how the spins of the electron and hole have been combined.

In British politics, the term ' Millbank Machine ' or ' Millbank tendency ' ( a play on ' Militant tendency ') has been linked with the activities of spin doctors.

Many Biblical scholars concluded that the account was a piece of political spin, which had been intended to disguise atrocities carried out by the tribe of Judah against Benjamin, probably in the time of King David as an act of revenge or spite by David against the associates of King Saul, by casting them further back in time, and adding a more justifiable motive ; more recently, scholars have suggested that it is more likely for the narrative to be based on a kernel of truth, particularly since it accounts for the stark contrast in the biblical narrative between the character of the tribe before the incident, and its character afterward.

India's traditional strengths have always been its line-up of spin bowlers and batsmen.

He has been perceived to have trouble against quality spin, especially against Indian off spinner Harbhajan Singh, who has dismissed Ponting on 13 occasions in International cricket, as of August 2010.

The gameplay has been changed as well, the Ryuuko Ranbu is blockable, Jack's drop kick only goes 2 / 3 of the screen, and Lee's claw spin has invincibility during the starting pose.

Although several plot threads spin out of the book, and Barker has promised at least one sequel, none have been written, and it is left to the imagination of the reader to work out what happens next.
