Now, glasses with in-built computer


Google is to soon launch hi-tech glasses with inbuilt computer displays, a media report said, quoting a company insider as saying.

Speculation is rife that hitech 'heads up display' glasses are being developed at Google's secret 'Google X' lab for months. Now, sources claim to have seen a prototype of the product, Daily Mail reported.

The glasses will be armed with cameras, an Android operating system, and could be on sale soon, the source said.

Google specialist Seth Weintraub says, "Our tipster said it looks something like Oakley Thumps. These glasses, have a front-facing camera and could aid in augmented reality applications.

"The heads up display is only for one eye and on the side. The navigation system currently used is a head tilting to scroll and click. We are told it's very quick to learn."

AMASIA - NEW CONTINENT


America and Eurasia will crash into each other over the North Pole in 50-200 million years time, according to scientists at Yale University.
They predict Africa and Australia will join the new "supercontinent" too, which will mark the next coming together of the Earth's land masses. 
The continents are last thought to have come together 300 million years ago into a supercontinent called Pangaea.
Details are published in the journal Nature.
The land masses of the Earth are constantly moving as the Earth's tectonic activity occurs. This generates areas such as the Mid-Atlantic Ridge, where Iceland has formed, and areas such as that off the coast of Japan, where one plate rides over another.
Geologists believe that, over billions of years, these shifting plates have driven the continents together periodically, creating the hypothesised supercontinents of Nuna 1.8 billion years ago, Rodinia a billion years ago, and then Pangaea 300 million years ago.
The next supercontinent has already been given the working title of Amasia, as it is expected to involve the convergence of the Americas and Asia.

Facebook reveals salaries of top execs




Facebook's top executives, including CEO Mark Zuckerberg, are eligible for twice-a-year bonuses of up to 45 per cent of their base salaries and other earnings, according to a regulatory filing.

Facebook Inc said in a filing with the Securities and Exchange Commission that it will pay Zuckerberg, 27, a base salary of $500,000 per year. Zuckerberg's 45 per cent target bonus will be based on his performance.

Chief Operating Officer Sheryl Sandberg will receive a base salary of $300,000. Her target bonus is also 45 per cent.

David Ebersman will continue to serve as chief financial officer and he will get a base salary of $300,000.

Mike Schroepfer, Facebook's vice president of engineering, will receive a base salary of $275,000. Both he and Ebersman have a target bonus of 45 per cent.

That said, the bulk of the windfall Zuckerberg and others will earn will be in the form of Facebook stock they own. The company said last week it plans to raise $5 billion in its IPO. If all goes as planned, Facebook could be worth as much as $100 billion.

Another executive, Vice President and General Counsel Theodore Ullyot, will receive a base salary of $275,000, according to the filing. He will also get a retention bonus of $400,000 per year for five years, as well as restricted stock and stock options.

Microsoft to unveil Windows 8 on Feb 29


SAN FRANCISCO: Microsoft revealed plans to unveil a test version of its latest Windows computer operating software later this month.

The US technology titan sent out invitations to a "Windows Consumer Preview" event to be held on February 29 at a hotel in Barcelona during a Mobile World Congress gathering in that city.

Microsoft promised to release more information closer to the end of the month.

The introduction of a test, or beta, version of Windows 8 to the public is expected to be accompanied by the opening of an " app store" stocked with mini-programs tailored for the next-generation operating system.

Interesting Facts About the Sun


Think you know everything there is to know about the Sun? Think again. Here are 10 interesting facts about the Sun, collected in no particular order. Some you might already know, and others will be totally new to you. Interesting facts after the break...

1. The Sun is the Solar System.

We live on the planet, so we think it's an equal member of the Solar System. But that couldn't be further from the truth. The reality is that the mass of the Sun accounts for 99.8% of the mass of the Solar System. And most of that final 0.2% comes from Jupiter. So the mass of the Earth is a fraction of a fraction of the mass of the Solar System. Really, we barely exist.

2. And the Sun is mostly hydrogen and helium.

If you could take apart the Sun and pile up its different elements, you'd find that 74% of its mass comes from hydrogen. with 24% helium. The remaining 2% is includes trace amounts of iron, nickel, oxygen, and all the other elements we have in the Solar System. In other words, the Solar System is mostly made of hydrogen.

3. The Sun is pretty bright.

We know of some amazingly large and bright stars, like Eta Carina and Betelgeuse. But they're incredibly far away. Our own Sun is a relatively bright star. If you could take the 50 closest stars within 17 light-years of the Earth, the Sun would be the 4th brightest star in absolute terms. Not bad at all.

4. The Sun is huge, but tiny.

With a diameter of 109 times the size the Earth, the Sun makes a really big sphere. You could fit 1.3 million Earths inside the Sun. Or you could flatten out 11,990 Earths to cover the surface of the Sun. That's big, but there are some much bigger stars out there. For example, the biggest star that we know of would almost reach Saturn if it were placed inside the Solar System.

5. The Sun is middle aged.

Astronomers think that the Sun (and the planets) formed from the solar nebula about 4.59 billion years ago. The Sun is in the main sequence stage right now, slowly using up its hydrogen fuel. But at some point, in about 5 billion years from now, the Sun will enter the red giant phase, where it swells up to consume the inner planets – including Earth (probably). It will slough off its outer layers, and then shrink back down to a relatively tiny white dwarf.

6. The Sun has layers.

The Sun looks like a burning ball of fire, but it actually has an internal structure. The visible surface we can see is called the photosphere, and heats up to a temperature of about 6,000 degrees Kelvin. Beneath that is the convective zone, where heat moves slowly from the inner Sun to the surface, and cooled material falls back down in columns. This region starts at 70% of the radius of the Sun. Beneath the convection zone is the radiative zone. In this zone, heat can only travel through radiation. The core of the Sun extends from the center of the Sun to a distance of 0.2 solar radii. This is where temperatures reach 13.6 million degrees Kelvin, and molecules of hydrogen are fused into helium.

7. The Sun is heating up, and will kill all life on Earth.

It feels like the Sun has been around forever, unchanging, but that's not true. The Sun is actually slowly heating up. It's becoming 10% more luminous every billion years. In fact, within just a billion years, the heat from the Sun will be so intense that liquid water won't exist on the surface of the Earth. Life on Earth as we know it will be gone forever. Bacteria might still live on underground, but the surface of the planet will be scorched and uninhabited. It'll take another 7 billion years for the Sun to reach its red giant phase before it actually expands to the point that it engulfs the Earth and destroys the entire planet.

8. Different parts of the Sun rotate at different speeds.

Unlike the planets, the Sun is great big sphere of hydrogen gas. Because of this, different parts of the Sun rotate at different speeds. You can see how fast the surface is rotating by tracking the movement of sunspots across the surface. Regions at the equator take 25 days to complete one rotation, while features at the poles can take 36 days. And the inside of the Sun seems to take about 27 days.

9. The outer atmosphere is hotter than the surface.

The surface of the Sun reaches temperatures of 6,000 Kelvin. But this is actually much less than the Sun's atmosphere. Above the surface of the Sun is a region of the atmosphere called the chromosphere, where temperatures can reach 100,000 K. But that's nothing. There's an even more distant region called the corona, which extends to a volume even larger than the Sun itself. Temperatures in the corona can reach 1 million K.

10. There are spacecraft observing the Sun right now.

The most famous spacecraft sent to observe the Sun is the Solar and Heliospheric Observatory, built by NASA and ESA, and launched in December, 1995. SOHO has been continuously observing the Sun since then, and sent back countless images. A more recent mission is NASA's STEREO spacecraft. This was actually two spacecraft, launched in October 2006. These twin spacecraft were designed to watch the same activity on the Sun from two different vantage points, to give a 3-D perspective of the Sun's activity, and allow astronomers to better predict space weather

Godse is often a misunderstood character..!


He is referred to as a Hindu fanatic. It is often hard to understand Godse because the Government of India had suppressed information about him. His court statements, letters etc. were all banned from the public until recently. Judging from his writings one thing becomes very clear – He was no fanatic. His court statements are very well read out and indicate a calm and collected mental disposition. He never even once speaks ill about Gandhi as a person, but only attacks Gandhi's policies which caused ruin and untold misery to Hindus. Another interesting point to note is that Godse had been working with the Hindu refugees fleeing from Pakistan. He had seen the horrible atrocities committed on them. Many women had their hands cut off, nose cut off, even little girls had been raped mercilessly. Despite this Godse did not harm even single Muslim in India which he could easily have. So it would be a grave mistake to call him a Hindu fanatic.

Let us start by studying the motive behind Godse's act. By seeing the nature of the assassination in public space and Godse's act of turning himself over to the Police, we can see that Godse did not do this for personal reasons. He very well knew that he would be hanged and his name would be disgraced as Gandhi was considered a saint. And again Godse could have ran away and escaped punishment. But he did the reverse. He called a police officer and courted arrest. Before we proceed it would be wise to understand the backdrop of the assassination.

The central government had taken a decision — Pakistan will not be given Rs 55 crores. On January 13 Gandhi started a fast unto death that Pakistan must be given the money. On January 13, the central government changed its earlier decision and announced that Pakistan would be given the amount. On January 13, Nathuram decided to assassinate Gandhi.

Nathuram Godse was a learned man, very sharp and intelligent – editor of "Agrani" (one of the most famous newspaper of that time – with Nana Aapte). In his last editorial of "Agrani" which he changed overnight – he said "Gandhi must be stopped – at any cost" and he justified why Gandhiji's assassination was not only inevitable but also a delayed action, sth tht shud've happened LONG AGO.

In Nathuram's words - " I don't refute Gandhi's theory of non-violence. He may be a saint but he is not a politician. His theory of non-violence denies self-defence and self-interest. The non-violence that defines the fight for survival as violence is a theory not of non-violence but of self-destruction.The division of the nation was an unnecessary decision. What was the percentage of the Muslim population as compared to the population of the nation? There was no need for a separate nation. Had it been a just demand, Maulana Azad would not have stayed back in India. But because Jinnah insisted and because Gandhi took his side, India was divided, in spite of opposition from the nation, the Cabinet. An individual is never greater than a nation.

In a democracy you cannot put forward your demands at knife-point. Jinnah did it and Gandhi stabbed the nation with the same knife. He dissected the land and gave a piece to Pakistan. We did picket that time but in vain. The Father of our Nation went to perform his paternal duties for Pakistan! Gandhi blackmailed the cabinet with his fast unto death. His body, his threats to die are causing the destruction — geographical as well as economical — of the nation. Today, Muslims have taken a part of the nation, tomorrow Sikhs may ask for Punjab. The religions are again dividend into castes, they will demand sub-divisions of the divisions. What remains of the concept of one nation, national integration? Why did we fight the British in unison for independence? Why not separately? Bhagat Singh did not ask only for an independent Punjab or Subhash Chandra Bose for an independent Bengal?

I am going to assassinate him in the open, before the public, because I am going to do it as my duty. If I do it surreptitiously, it becomes a crime in my own eyes. I will not try to escape, I will surrender and naturally I will be hanged. One assassination, one hanging. I don't want two executions for one assassination and I don't want your involvement, participation or company. (This was for Nana-Apte and Veer Savarkar as they were against ghandhi's policies too, Godse wanted to assassinate gandhi all by himself and took promise from Nana Apte that he will continue helping Veer Savarkar in rebuilding India as a strong free nation.)

On January 30, I reached Birla Bhavan at 12 pm. Gandhi was sitting outside on a cot enjoying the sunshine. Vallabhbhai Patel's granddaughter was sitting at his feet. I had the revolver with me. I could have assassinated him easily then, but I was convinced that his assassination was to be a punishment and a sentence against him, and I would execute him. I wanted witnesses for the execution but there were none. I did not want to escape after the execution as there was not an iota of guilt in my mind. I wanted to surrender, but surrender to whom? There was a good crowd to collect for the evening prayers. I decided on the evening of January 30 as the date for Gandhi's execution.

Gandhi climbed the steps and came forward. He had kept his hands on the shoulders of the two girls. I wanted just three seconds more. I moved two steps forward and faced Gandhi. Now I wanted to take out the revolver and salute him for whatever sacrifice and service he had made for the nation. One of the two girls was dangerously close to Gandhi and I was afraid that she might be injured in the course of firing. As a precautionary measure I went one more step ahead, bowed before him and gently pushed the girl away from the firing line. The next moment I fired at Gandhi. Gandhi was very weak, there was a feeble sound like 'aah' (There are proof that Gandhi did NOT say "Hey Raam" at that time – it's just made up stuff ) from him and he fell down.

After the firing I raised my hand holding the revolver and shouted, 'Police, police'. For 30 seconds nobody came forward and I scanned the crowd. I saw a police officer. I signalled to him to come forward and arrest me. He came and caught my wrist, then a second man came and touched the revolver… I let it go…"
