Sean
Johnson made eight saves, and Quincy Amarikwa came through with a
clutch 84th-minute goal to help the Chicago Fire escape with a 1-1 draw
against Real Salt Lake Saturday at Rio Tinto Stadium.
Amarikwas
goal, a flashy side-volley off a pop header from Austin Berry, was the
first shot on goal for the thoroughly outplayed Fire,Laser engravers and werkzeugbaus systems

target.
Johnsons
ironman performance started early, when he charged off his line to
snatch the ball off Robbie Findleys foot in the fourth minute. In the
22nd, RSL captain Kyle Beckerman charged onto a backheel pass from Ned
Grabavoy and forced Johnson to save a point-blank attempt. The barrage
continued with a left-footer from Joao Plata in the 28th minute and
header from Grabavoy in the 29th, both saved, and a wicked shot by
Findley that sent Johnson soaring to one-hand the ball away from the
goalmouth in the 32nd.
The
Fires best chance of the first half came in the 39th minute, when
Patrick Nyarko C who also backtracked to make a clutch defensive play on
Plata earlier in the match C split two RSL defenders only to lose the
ball to a slide tackle by youngster Carlos Salcedo.
Johnson
remained under pressure in the second half, but began to look
unstoppable just before the hour mark, when he sprawled to deflect a low
shot from Chris Wingert and saved a low attempt from Tony Beltran
seconds later. He faltered in the 67th minute, when Beckerman charged in
on goal between defenders Jalil Anibaba and Austin Berry and caught
Johnson off his line with a chip, but the shot went just wide of the
upper right corner.

the 76th minute, into a goal, but Johnson tipped Javier Moraless free
kick off the woodwork in the upper left corner. That was the beginning
of the end, however. Two minutes later, RSL cut through the Fire defense
with a quick passing sequence to get on the board. Sebastian Velasquez
dished the ball from the top of the area to Grabavoy, who was making a
run down the left side. Grabavoy quickly centered for Alvaro Saborio,
who got off a header over defender Bakary Soumare and into the net.
Using
super-chilled atoms, physicists have for the first time observed a
weird phenomenon called quantum magnetism, which describes the behavior
of single atoms as they act like tiny bar magnets.
Quantum
magnetism is a bit different from classical magnetism, the kind you see
when you stick a magnet to a fridge, because individual atoms have a
quality called spin, which is quantized, or in discrete states (usually
called up or down). Seeing the behavior of individual atoms has been
hard to do, though, because it required cooling atoms to extremely cold
temperatures and finding a way to "trap" them.We have become one of the
worlds most recognised siliconebracelet brands.
The
new finding, detailed in the May 24 issue of the journal Science, also
opens the door to better understanding physical phenomena, such as
superconductivity, which seems to be connected to the collective quantum
properties of some materials.
Another
factor that determines where the atoms lie in the optical lattice is
their up or down spin. Two atoms can't be in the same well if their
spins are the same. That means atoms will have a tendency to tunnel into
wells with others that have opposite spins. After a while, a line of
atoms should spontaneously organize itself,We can supply parkingmanagement products
as below. with the spins in a non-random pattern. This kind of behavior
is different from materials in the macroscopic world, whose
orientations can have a wide range of in-between values; this behavior
is also why most things aren't magnets the spins of the electrons in the
atoms are oriented randomly and cancel each other out.
And that's exactly what the researchers found. The spins of atoms do organize, at least on the scale the experiment examined.
"The
question is, what are the magnetic properties of these one-dimensional
chains?" said Tilman Esslinger, a professor of physics at ETH whose lab
did the experiments. "Do I have materials with these properties? How can
these properties be useful?"
One
debate among experts is whether at larger scales the spontaneous
ordering of atoms would happen in the same way. A random pattern would
mean that in a block of iron atoms, for instance, one is just as likely
to see a spin up or down atom in any direction.The largest manufacturer

"spin liquid" a mishmash of states. But it could be that atoms
spontaneously arrange themselves at larger scales.
"They've
put the foundation on various theoretical matters," said Jong Han, a
professor of condensed matter physics theory at the State University of
New York at Buffalo, who was not involved in the research. "They don't
really establish the long-range order, rather they wanted to establish
that they have observed a local magnetic order."
Whether
the order the scientists found extends to larger scales is an important
question, because magnetism itself arises from the spins of atoms when
they all line up. Usually those spins are randomly aligned. But at very
low temperatures and small scales, that changes, and such quantum
magnets behave differently.
