The world appears in constant flux.

Fluence is the time integral of flux.

The systematics of the Anatidae are in a state of flux.

For the reverse process, there are two possibilities spontaneous emission of a photon, and a return to the lower energy state that is initiated by the interaction with a passing photon.

This ethos will also help us maximize the potential benefits of such flux.

In physics, a photon is usually denoted by the symbol γ (the Greek letter gamma).

Once in open space, a photon from the Sun takes only 8.3 minutes to reach Earth.

Fissures within the Egyptian regime suggest that in Hosni Mubarak s entourage, too, fear is in flux.

The original photon is not absorbed by the atom, and so the result is two photons of the same frequency.

Today s flux in the Middle East is a highly ambivalent affair, because the situation can improve or (more likely) deteriorate.

On the internet, official knowledge is mixed up with the flux of global data and treated like any other information.

The Arab world is also in a state of flux after an emotional 22 days of Israel s televised bombardment of Gaza.

In one example, for each bit in the random sequence that is to be produced, a photon is sent to a beam splitter.

As it stands, political priorities are constantly in flux, with individual dossiers losing their centrality, and even vanishing, from year to year.

And likewise, not all particles interact with the Higgs field those that do so have mass, while the others (such as the photon) do not.

This disturbance produces an electromagnetic wave (of light, infrared, ultraviolet etc.), and this wave is nothing other than a photon and thus one of the force carrier bosons.

But, given the profound uncertainty of a world in flux, as well as the dangers of miscalculation as the Soviet empire collapsed, prudent management trumped grand visions.

Numerology of gluons Unlike the single photon of QED or the three W and Z bosons of the weak interaction, there are eight independent types of gluon in QCD.

This correlation indicates that the origin of the light emission was a flux of electrons moving along the crust magnetic lines and exciting the upper atmosphere of Mars.

In fact, if you can read this article, it is thanks to an extraordinarily banal boson the photon, or the light particle which is the messenger of the electromagnetic force.

That map has been in constant flux for the last 60 years, during which the main players Egypt, Iraq, Saudi Arabia, Syria, Israel, and Iran have formed and broken alliances.

Its distance from Jupiter also means that the charged particle flux from Jupiter's magnetosphere at its surface is relatively low about 300 times lower than, for example, that at Europa.

Now it may look like a tasty morsel, or a pig's head with wings but if it's attacked, it puts out a barrage of light in fact, a barrage of photon torpedoes.

With regard to the text of Alfred Nobel's will, which requires that a Nobel Laureate confer the greatest benefit on mankind, Einstein's introduction of the photon by far surpasses the theory of relativity!

BERLIN The eruption of the Arab revolts in late 2010 and early 2011 put power relations among Middle Eastern countries in a state of flux, and both winners and losers have emerged.

This is obviously the case with President Barack Obama s recent address to the Muslim world in Cairo, because mere coincidence or excellent timing? things in the Middle East have been in flux ever since.

He treated the interaction between a charge and an electromagnetic field as a small perturbation that induces transitions in the photon states, changing the numbers of photons in the modes, while conserving energy and momentum overall.

The unification of the photon with W and Z gauge bosons in the electroweak interaction was accomplished by Sheldon Glashow, Abdus Salam and Steven Weinberg, for which they were awarded the 1979 Nobel Prize in physics.

But what seemed to be missing in China was a full recognition of just how uncertain things have become in the US, and how, with a new president, almost everything is in an unprecedented state of flux.

This is much more difficult, since if you know the total flux through a given surface, that gives almost no information about the electric field, which (for all you know) could go in and out of the surface in arbitrarily complicated patterns.

Inspired by Crass, its Dial House commune, and its independent Crass Records label, a scene developed around British bands such as Subhumans, Flux of Pink Indians, Conflict, Poison Girls, and The Apostles that was concerned as much with anarchist and DIY principles as it was with music.

... for at the moment that the observer approaches, then they become other ... so that you cannot get any further in knowing their nature or state ... but if that which knows and that which is known exist ever ... then I do not think they can resemble a process or flux ...

To argue that peacemaking can t be successful when governments and regimes are in flux ignores the fact that it is precisely in such circumstances that outsiders can help shape the process. Instead of operating in an environment with little influence or room for maneuver, pushing the peace process now could help endear the Arab public to the West and give the US more sway in the new Middle East.
