Tottenham full-back Benoit Assou-Ekotto has revealed his fear at witnessing Fabrice Mumba suffer a heart attack on the pitch during his side's abandoned game against Bolton.

The Cameroonian was close to Muamba when he collapsed and has since gone on to admit that the whole ordeal has left a mark on him.

"When I saw him lying on the pitch at White Hart Lane, I was scared," he told The Evening Standard.
"Scared for him, scared for his family, his friends and all those people who know him and who care about him

"I was also scared because he was just like me. He is young, supposedly fit - an athlete - who a few seconds ago was running up and down the same pitch as me

"I had flashbacks of what had happened to my countryman, the late Marc-Vivien Foe.

"You want to stop these thoughts but the pictures keep coming into your head and I must say I was scared.

"Scared as I wondered how it could all just end like that for a young man? I could see the same questions in the eyes of my team-mates, the Bolton players, our bosses and their colleagues.

"And I learnt a new word as I tried to make sense of it late on Saturday: surreal."

Despite being shaken by the incident, the left-back expressed his belief that it has brought people together and went on to praise both sides' managers and fans for their reaction to the game being called off.

"When the referee spoke with the two managers about abandoning the game, there was no hesitation," he added.

"When it was announced to the fans that the game would not continue, there were no complaints.

"People who had travelled from far and near were all focused on the wellbeing of Fabrice and nothing else mattered.

"They silently made their ways out of the stadium. When we sat in the dressing room afterwards we spoke only of Fabrice."

The Cameroon international also believes that the way the footballing community and the wider world at large has reacted to Muamba's plight has been touching.

He continued: "I have seen messages from people from the very far corners of the world all wishing Fabrice well. I have seen people who care very little for football talk about Fabrice.

"This is the true beauty and power of football. It connects people in a way that is hard to describe. It is this that I feel is the magic of the moment."

Earth hour Time 2012, Ini Aksiku mana Aksimu...?

March 31, 2012, at 08:30 to 09:30 local time in unison most of the people of the world will celebrate Earth Hour, an annual event that shows our concern for our planet. The event was conducted in the form of a power outage for 1 hour to conserve energy use.Earth has given so much to our lives, but how many problems we have done? abundant natural resources have resulted in the destruction of nature, so it is natural as nature often tell us through the events are capable of shocking the world.

Ineffective use of energy can provide harm to ourselves and even others. Come and take the people around us to make use of energy in order to be effective in order to save place to live for our children and grandchildren in the future.

Let's say earth hour together. Switch off your electricity for 1 hour for a better world. (wait for update)

"Alien" Particles Found Invading Our Solar System—A First (nationalgeographic.com

When I was open the national geographic site, I actually interested on their post about particle which talk about an "alien particle" has been found in our solar system. I do not understand about it? cause it is not logic that there is another life beside earth? NASA may be found some compound which support there is a life on that particle. Wow, it is so amazing if there some biological life on it. Here some information about the phenomena alien Particle according nationalgeographic.com 

For the first time, a NASA spacecraft has directly observed "alien" particles that came from beyond our solar system, astronomers announced today.
The discovery not only gives us a glimpse of what exists in the so-called interstellar medium—the matter between stars—but also offers clues to the anatomy of our local galactic neighborhood.
Orbiting Earth some 200,000 miles (322,000 kilometers) away, the Interstellar Boundary Explorer (IBEX) spacecraft was able to snag samples of hydrogen, oxygen, and neon that came from interstellar space.
"It's exciting to be able to have these first observations of alien matter—stuff that didn't come from our sun or the planets, but came from the outside of our solar system, from other parts of the galaxy," David McComas, team leader for the IBEX program, said during a NASA news conference Tuesday.
"We think these are really important measurements, because these elements are the fundamental building blocks of stars, planets, and people."

IBEX Find a "15-Billion-Mile Hole-in-One"
Since its launch in October 2008, the IBEX probe has been mapping the boundary of the solar system, called the heliosphere.
This bubble in the Milky Way galaxy is created by solar wind, which is the stream of charged particles that's constantly blowing out from the sun in all directions.
The edge of the heliosphere lies about a hundred times farther from us than Earth does from the sun, and it shields the inner solar system from deadly cosmic radiation.
That's because the heliosphere and its associated magnetic field push away damaging charged particles. These particles—remnants from supernovae that are dispersed through interstellar space—flow toward us at 50,000 miles (80,000 kilometers) an hour.
(Also see "Frothy Magnetic-Bubble Sea Found at Solar System's Edge.")
But half of the particles in the interstellar wind are neutral, and these uncharged atoms can make it into our solar system.
A few of these neutral hydrogen, oxygen, and neon particles then made it all the way to Earth, where IBEX was able to detect them, McComas said during the conference.
"I like to call it the 15-billion-mile [24-billion-kilometer] hole-in-one," he said.
Solar System Rich in Oxygen?
An analysis of the new IBEX data compared the ratios of oxygen to neon from interstellar space with the ratios of these atoms native to our solar system.
The results show that our solar system appears to contain more oxygen than surrounding interstellar space.
This may mean that our solar system migrated to its current location from a more oxygen-rich environment. Or it's possible a lot of oxygen is trapped within dust grains or ice in the interstellar medium.
(Related: "Mystery Space 'Ribbon' Found at Solar System's Edge.")
IBEX also measured the speed of the interstellar wind, revealing that the wind is moving about 7,000 miles (11,000 kilometers) an hour slower than previously recorded.
Combined with previous data on nearby interstellar clouds—gossamer blobs of gas and dust many light-years across—the team was able to more precisely pinpoint our location in the local galactic neighborhood.
Our solar system appears to sit at the edge of one of many low-density interstellar clouds that move through this region of the galaxy—and we may actually exit the cloud in the next few thousand years, the data show.
"It's so exciting to know where our sun is in relation to local clouds. It really puts our sun in context for the first time," said Seth Redfield, an astronomer from Wesleyan University in Middletown, Connecticut, who's involved with IBEX.
"Our location within our local interstellar cloud is important," Redfield added, "because the heliosphere structure changes depending on where it is inside a cloud or outside, and so it has consequences for how well it shields us from those deadly cosmic rays."
The new IBEX results appear in a series of papers in the February edition of Astrophysical Journal Supplements.

Know the superconducting material

A. History and Background 

The first superconductor was discovered by a Dutch physicist, and his name Heike Kamerlingh Onnes, who is a researcher at Leiden University in 1911. On July 10, 1908, Onnes succeeded in liquefying helium by cooling elements up to 4 Kelvin or -269 Celsius. Then in 1911, Onnes began to study the electrical properties of metals at very cold temperatures, probably due to the hypothesis that high rates of movement of electrons in the phonon. At the time it was known that the resistance of a metal will come down when cooled below room temperature, but no one can know how the lower limit of resistance is achieved when the metal temperature approaches 0 K or absolute zero.

 
Some expert scientists at that time as William Kelvin predicted that electrons flowing in the conductor will stop when the temperature reaches absolute zero. On the other hand, other scientists, including Onnes estimated that the barriers will disappear in these circumstances. To find out the truth, Onnes then drain current in a very pure mercury wire and then measure the resistance while lowering the temperature. At a temperature of 4.2 K, Onnes was surprised to find that its resistance suddenly disappeared. Current flows through the wire mercury constantly.

superconductors made ​​with the aim to obtain the energy efficiency of each machine that has been made ​​before, it is of course very beneficial in helping every human activities. Imagine if a superconductor can be created and used in the quality of your internet or telephone network, you will get good again without costing so much. Now it's like super-fast trains have used the principle of the superconductor has zero resistance.

B. Defenition

Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic fields occurring in certain material when cooled below a characteristic critical temperature. which means there is no resistance when the electrons moving from one point to the another point.

Like ferromagnetism and atomic spectral lines, superconductivity is a quantum mechanical phenomenon. It is characterized by the Meissner effect, the complete ejection of magnetic field lines from the interior of the superconductor as it transitions into the superconducting state. The occurrence of the Meissner effect indicates that superconductivity cannot be understood simply as the idealization of perfect conductivity in classical physics.
