Gallium – A Rare Metal with Interesting Properties
Apr92013

A truly peculiar metal with an ultra low melting point of just 29.76 °C (85.57 °F) and the ability to attack most other metals by diffusing into their metal lattice (greatly weakening their structure).

In 1871, existence of gallium was first predicted by Russian chemist Dmitri Mendeleev, who named it "eka-aluminium" on the basis of its position in his periodic table. He also predicted several properties of the element, which correspond closely to real gallium properties, such as density, melting point, oxide character and bonding in chloride. Gallium was discovered spectroscopically by French chemistPaul Emile Lecoq de Boisbaudran in 1875 by its characteristic spectrum (two violet lines) in an examination of a sphalerite sample.



Elemental gallium is not found in nature, but it is easily obtained by smelting. Very pure gallium metal has a brilliant silvery color and its solid metal fractures conchoidally like glass. Gallium easily alloys with many metals, and is used in small quantities as a plutonium-gallium alloy in the plutonium cores of nuclear bombs, to help stabilize the plutonium crystal structure.

Today, almost all gallium is used for microelectronics (gadgets like your phone, TV's and even cars). Gallium arsenide, the primary use of gallium, is used in microwave circuitry and infrared applications.

Take a look at the following video and see this metal in action as it destroys an Aluminum soda can. Unreal!

It can be a case of 1.5 Billion years old human civilization in line with the Indian scriptures who claim the human civilization to be as old as 1.97 Billion years old.

The Vedic calculations of Time & creation

The Present Age of Cosmos according to the Vedic System is as follows:
There are 14 Manvantaras altogether. The present period is passing through the seventh Manvantara called Vaivaswata Manvantara.
One Manvantara consists of 71 Mahayugs, out of which 27 Mahayugs have already passed. We are passing through the first phase of the Kali Yuga which itself is the third Yuga of the 28th Mahayuga and which has come after the passing of Satya Yuga, Treta and Dwapar Yuga.
The time period of Manvantara (exclusive period, when the earth is submerged in water, in the beginning and in the end) = 306,720,000 years
1) Multiplying these years by 6 = 30,67,20,000 x 6 (Because we are in the midst of 7th Manvantara, of the Svetvaaraah Kalpa and 6 Manvantaras have already passed) = 1,8,0,300,000 years
The time period of Pralaya consists of 17,28,000 years since 7 Pralayas have passed, after the end of 6th Kalpa and before the beginning of 7th Kalpa, so 17,28,000x 7 = 12,096,000 years
Adding we have:
1,840,300,000 + 120 96 000 + 1,852,396,000 years
Therefore, after 1,85,24,16,000 years ‘VAIVASVAT MANVANTARA’ has started.
2) 27 Mahayugs with each Mahayuga consisting of 43,20,000 years. 43,20,000 x 27 = 116,640,000 years have passed
Total = 1,96,90,56,000 years
Kalpa consist of 4,32,00,00,000 years and out of these 1,97,29,49,101 years have passed. Therefore, the earth’s existence, according to the calculations devised by our ancient sages, comes up to 1,97,29,49,101 years till date. It is interesting to note that according to scientific calculations, the age of the cosmos is estimated between 15 and 20 billion years.

It can take a photon 40,000 years to travel from the core of the sun to its surface, but only 8 minutes to travel the rest of the way to Earth

A photon travels, on average, a particular distance, d, before being briefly absorbed and released by an atom, which scatters it in a new random direction.From the core to the sun’s surface (696,000 kilometers) where it can escape into space, a photon needs to make a huge number of drunken jumps. The calculation is a little tricky, but the conclusion is that a photon takes between many thousands and many millions of years to drunkenly wander to the surface of the Sun. In a way, the light that reaches us today is energy produced maybe millions of years ago. Amazing!

The first Digital Weapon of the world

In January 2010, inspectors with the International Atomic Energy Agency visiting the Natanz uranium enrichment plant in Iran noticed that centrifuges used to enrich uranium gas were failing at an unprecedented rate. The cause was a complete mystery—apparently as much to the Iranian technicians replacing the centrifuges as to the inspectors observing them.

Five months later a seemingly unrelated event occurred. A computer security firm in Belarus was called in to troubleshoot a series of computers in Iran that were crashing and rebooting repeatedly. Again, the cause of the problem was a mystery. That is, until the researchers found a handful of malicious files on one of the systems and discovered the world’s first digital weapon.

Stuxnet, as it came to be known, was unlike any other virus or worm that came before. Rather than simply hijacking targeted computers or stealing information from them, it escaped the digital realm to wreak physical destruction on equipment the computers controlled.

Countdown to Zero Day: Stuxnet and the Launch of the World’s First Digital Weapon, written by WIRED senior staff writer Kim Zetter, tells the story behind Stuxnet’s planning, execution and discovery. In this excerpt from the book, which will be released November 11, Stuxnet has already been at work silently sabotaging centrifuges at the Natanz plant for about a year. An early version of the attack weapon manipulated valves on the centrifuges to increase the pressure inside them and damage the devices as well as the enrichment process. Centrifuges are large cylindrical tubes—connected by pipes in a configuration known as a “cascade”—that spin at supersonic speed to separate isotopes in uranium gas for use in nuclear power plants and weapons. At the time of the attacks, each cascade at Natanz held 164 centrifuges. Uranium gas flows through the pipes into the centrifuges in a series of stages, becoming further “enriched” at each stage of the cascade as isotopes needed for a nuclear reaction are separated from other isotopes and become concentrated in the gas.

Excerpted
As the excerpt begins, it’s June 2009—a year or so since Stuxnet was first released, but still a year before the covert operation will be discovered and exposed. As Iran prepares for its presidential elections, the attackers behind Stuxnet are also preparing their next assault on the enrichment plant with a new version of the malware. They unleash it just as the enrichment plant is beginning to recover from the effects of the previous attack. Their weapon this time is designed to manipulate computer systems made by the German firm Siemens that control and monitor the speed of the centrifuges. Because the computers are air-gapped from the internet, however, they cannot be reached directly by the remote attackers. So the attackers have designed their weapon to spread via infected USB flash drives. To get Stuxnet to its target machines, the attackers first infect computers belonging to five outside companies that are believed to be connected in some way to the nuclear program. The aim is to make each “patient zero” an unwitting carrier who will help spread and transport the weapon on flash drives into the protected facility and the Siemens computers. Although the five companies have been referenced in previous news reports, they’ve never been identified. Four of them are identified in this excerpt.

The Lead-Up to the 2009 Attack
The two weeks leading up to the release of the next attack were tumultuous ones in Iran. On June 12, 2009, the presidential elections between incumbent Mahmoud Ahmadinejad and challenger Mir-Hossein Mousavi didn’t turn out the way most expected. The race was supposed to be close, but when the results were announced—two hours after the polls closed—Ahmadinejad had won with 63 percent of the vote over Mousavi’s 34 percent. The electorate cried foul, and the next day crowds of angry protesters poured into the streets of Tehran to register their outrage and disbelief. According to media reports, it was the largest civil protest the country had seen since the 1979 revolution ousted the shah and it wasn’t long before it became violent. Protesters vandalized stores and set fire to trash bins, while police and Basijis, government-loyal militias in plainclothes, tried to disperse them with batons, electric prods, and bullets.

That Sunday, Ahmadinejad gave a defiant victory speech, declaring a new era for Iran and dismissing the protesters as nothing more than soccer hooligans soured by the loss of their team. The protests continued throughout the week, though, and on June 19, in an attempt to calm the crowds, the Ayatollah Ali Khamenei sanctioned the election results, insisting that the margin of victory—11 million votes—was too large to have been achieved through fraud. The crowds, however, were not assuaged.

The next day, a twenty-six-year-old woman named Neda Agha-Soltan got caught in a traffic jam caused by protesters and was shot in the chest by a sniper’s bullet after she and her music teacher stepped out of their car to observe.

Two days later on June 22, a Monday, the Guardian Council, which oversees elections in Iran, officially declared Ahmadinejad the winner, and after nearly two weeks of protests, Tehran became eerily quiet. Police had used tear gas and live ammunition to disperse the demonstrators, and most of them were now gone from the streets. That afternoon, at around 4:30 p.m. local time, as Iranians nursed their shock and grief over events of the previous days, a new version of Stuxnet was being compiled and unleashed.

Recovery From Previous Attack
While the streets of Tehran had been in turmoil, technicians at Natanz had been experiencing a period of relative calm. Around the first of the year, they had begun installing new centrifuges again, and by the end of February they had about 5,400 of them in place, close to the 6,000 that Ahmadinejad had promised the previous year. Not all of the centrifuges were enriching uranium yet, but at least there was forward movement again, and by June the number had jumped to 7,052, with 4,092 of these enriching gas. In addition to the eighteen cascades enriching gas in unit A24, there were now twelve cascades in A26 enriching gas. An additional seven cascades had even been installed in A28 and were under vacuum, being prepared to receive gas.
