MotoGP™ Rewind: Le Mans

Relive all the action from a very wet fourth round of the 2012 MotoGP™ championship at last weekend's Monster Energy Grand Prix de France in Le Mans.

US Assault Ship Docks in Hong Kong

The US Navy assault ship, the USS Makin Island, arrives to dock in Hong Kong on Friday, May 25th. The ship joins the amphibious transport dock USS New Orleans, which arrived two days earlier.

The visit comes amid a seven-week stand off between Chinese forces and the Philippines over the disputed Scarborough Shoal in the South China Sea.

China, the Philippines and several other countries all have competing territorial claims in the sea, which carries 5 trillion dollars worth of ship bourn trade annually and boasts 10 percent of global fish recourses. The US also claims national interests in the South China Sea, and recently took part in military exercise with the Philippines, to the anger of the Chinese regime.

The USS Makin Island wasn't involved in these exercises, but Captain Pringle says the ship stands ready to ensure peace in the region.

[Captain Cedric Pringle, Commanding Officer]:
"The navy's position is consistent with the U.S. position. Our policy is that we hope that the claims involved and the claimants involved resolve them peacefully."

Reporter: "and if they don't? "

"Well, we're always obligated to ensure peace and stability throughout the region."

Despite the looming tensions in the region, some crewmembers with connections to Hong Kong are taking time to relax.

[Sergeant Kong, US Navy]:
"But I grew up in the United States, for so many years not being back for 15 or 16 years. So now that I'm finally back, I get to see my grandmother, my uncle, my aunt and I miss them very much. So it's a pleasure to be here and love Hong Kong."

The USS Makin Island was commissioned in 2009. The ship has a primary mission of deploying marine landing forces and a secondary mission of sea control and power projection. It is currently deployed as part of the US Navy's 7th fleet.

Look closely and you’ll see two moving objects in this. The most obvious one is a meteor however, more subtly in the middle towards the top right, there’s a small object moving slowly up and that is a fuselage of a Russian rocket breaking up in the upper atmosphere.

A wide field meteor camera at NASA's Marshall Space Flight Center recorded this spectacular meteor breaking up in Earth's atmosphere on Sept. 30, 2011, 8:37 p.m. EDT. Also visible is a star-like object moving slowly toward the upper middle of the field of view -- the upper stage of the Zenit booster that launched the Russian Cosmos 2219 intelligence satellite back in 1992. Orbiting 500 miles above Earth, this empty rocket body can get bright enough to be seen with the unaided eye.

Cosmic Journeys : The Riddle of AntiMatter

Watch this and other space videos at http://SpaceRip.com

In high-res 1080p. Explores one of the deepest mysteries about the origin of our universe. According to standard theory, the early moments of the universe were marked by the explosive contact between subatomic particles of opposite charge. Featuring short interviews with Masaki Hori, Tokyo University and Jeffrey Hangst, Aarhus University.

Scientists are now focusing their most powerful technologies on an effort to figure out exactly what happened. Our understanding of cosmic history hangs on the question: how did matter as we know it survive? And what happened to its birth twin, its opposite, a mysterious substance known as antimatter? 

A crew of astronauts is making its way to a launch pad at the Kennedy Space Center in Florida. Little noticed in the publicity surrounding the close of this storied program is the cargo bolted into Endeavor's hold. It's a science instrument that some hope will become one of the most important scientific contributions of human space flight.

It's a kind of telescope, though it will not return dazzling images of cosmic realms long hidden from view, the distant corners of the universe, or the hidden structure of black holes and exploding stars.

Unlike the great observatories that were launched aboard the shuttle, it was not named for a famous astronomer, like Hubble, or the Chandra X-ray observatory.

The instrument, called the Alpha Magnetic Spectrometer, or AMS. The promise surrounding this device is that it will enable scientists to look at the universe in a completely new way. 

Most telescopes are designed to capture photons, so-called neutral particles reflected or emitted by objects such as stars or galaxies. AMS will capture something different: exotic particles and atoms that are endowed with an electrical charge. The instrument is tuned to capture "cosmic rays" at high energy hurled out by supernova explosions or the turbulent regions surrounding black holes. And there are high hopes that it will capture particles of antimatter from a very early time that remains shrouded in mystery.

The chain of events that gave rise to the universe is described by what's known as the Standard model. It's a theory in the scientific sense, in that it combines a body of observations, experimental evidence, and mathematical models into a consistent overall picture. But this picture is not necessarily complete.

The universe began hot. After about a billionth of a second, it had cooled down enough for fundamental particles to emerge in pairs of opposite charge, known as quarks and antiquarks. After that came leptons and antileptons, such as electrons and positrons. These pairs began annihilating each other.

Most quark pairs were gone by the time the universe was a second old, with most leptons gone a few seconds later. When the dust settled, so to speak, a tiny amount of matter, about one particle in a billion, managed to survive the mass annihilation. 

That tiny amount went on to form the universe we can know - all the light emitting gas, dust, stars, galaxies, and planets. To be sure, antimatter does exist in our universe today. The Fermi Gamma Ray Space Telescope spotted a giant plume of antimatter extending out from the center of our galaxy, most likely created by the acceleration of particles around a supermassive black hole. 

The same telescope picked up signs of antimatter created by lightning strikes in giant thunderstorms in Earth's atmosphere. Scientists have long known how to create antimatter artificially in physics labs - in the superhot environments created by crashing atoms together at nearly the speed of light.

Here is one of the biggest and most enduring mysteries in science: why do we live in a matter-dominated universe? What process caused matter to survive and antimatter to all but disappear? One possibility: that large amounts of antimatter have survived down the eons alongside matter.

In 1928, a young physicist, Paul Dirac, wrote equations that predicted the existence of antimatter. Dirac showed that every type of particle has a twin, exactly identical but of opposite charge. As Dirac saw it, the electron and the positron are mirror images of each other. With all the same properties, they would behave in exactly the same way whether in realms of matter or antimatter. It became clear, though, that ours is a matter universe. The Apollo astronauts went to the moon and back, never once getting annihilated. Solar cosmic rays proved to be matter, not antimatter.

It stands to reason that when the universe was more tightly packed, that it would have experienced an "annihilation catastrophe" that cleared the universe of large chunks of the stuff. Unless antimatter somehow became separated from its twin at birth and exists beyond our field of view, scientists are left to wonder: why do we live in a matter-dominated universe?

We can see who visited our profile?
What explains the actual Facebook

It is very common for unscrupulous individuals trying to spreadmalicious applications and other malevolent account the cheatingchristestou Facebook.

The most classic example is applications and publications are thosewho say they can see who visited your profile.

Eg "65 people have seen my profile this week. 65 people have seenmy profile today. Check your own at ... "

It explains itself but Facebook does not offer any application or groupthe necessary technical means to track who is watching your profile (Chronology), nor to see statistics that show who and how often yousee a particular content.

Moreover explains that if an application claims to offer this feature, the user should be reported in the "Information" in the application by pressing "Report application" at the bottom of the page or"Reference" at the bottom of any page of the application.
