Li-Fi to replace Wi-Fi in China 

Four computers can be connected to internet through one- watt LED bulb using light as a carrier instead of traditional radio frequencies, as in Wi-Fi, said Chi Nan, an information technology professor with Shanghai's Fudan University.
Chinese scientists have successfully developed a new cheaper way of getting connected to internet by using signals sent through light bulbs instead of radio frequencies as in 'Wi-Fi', a move expected to radically change process of on-line connectivity.

A SMALL STORY ON HOW A PEACEFUL MIND CAN DO WONDERS

"There once was a farmer who discovered that he had lost his watch in the barn. It was no ordinary watch because it had sentimental value for him.

After searching high and low among the hay for a long while; he gave up and enlisted the help of a group of children playing outside the barn.

He promised them that the person who found it would be rewarded.

Hearing this, the children hurried inside the barn, went through and around the entire stack of hay but still could not find the watch. Just when the farmer was about to give up looking for his watch, a little boy went up to him and asked to be given another chance.

The farmer looked at him and thought, “Why not? After all, this kid looks sincere enough.”

So the farmer sent the little boy back in the barn. After a while the little boy came out with the watch in his hand! The farmer was both happy and surprised and so he asked the boy how he succeeded where the rest had failed.

The boy replied, “I did nothing but sit on the ground and listen. In the silence, I heard the ticking of the watch and just looked for it in that direction.”

"A peaceful mind can think better than a worked up mind. Allow a few minutes of silence to your mind every day, and see, how sharply it helps you to set your life the way you expect it to be!"

A STORY ABOUT ALBERT EINSTEIN LECTURE ON RELATIVITY

There is a story about how Albert Einstein was travelling to universities, giving lectures on his famous theory of relativity. One day while on their way to a university,

The driver said:" Dr. Einstein, I've heard that lecture more than 30 times. I have learned it by heart and bet I could give it myself."

"Well, I'll give you the chance," said Einstein,

"They don't know me at the next school, so when we get there I'll put on your cap and you introduce yourself as me and give the lecture." Einstein continued.

At the hall, the driver gave Einstein's lecture so wonderfully that he didn't make any mistakes.

When he finished, he started to leave, but one of the professors stopped him and asked him a question which was very difficult. The aim of the question was not gaining knowledge but embarrassing Einstein.

The driver thought fast.

"The answer to that problem is so simple," he said,

"I'm surprised you have to ask me. In fact, to show you just how simple it is, I'm going to ask my driver to come up here and answer your question."!

Then Einstein stood up and gave an incredible answer to the question of that professor.

>> Moral of the story: No matter how genius you pretend to be, there is always someone who is more genius than you despite his position....

INSIDE NUCLEAR POWER GENERATION STATION

Joshua Bell at metro station in Washington DC

“A man sat at a metro station in Washington DC and started to play the violin; it was a cold January morning. He played six Bach pieces for about 45 minutes. During that time, since it was rush hour, it was calculated that 1,100 people went through the station, most of them on their way to work.

Three minutes went by, and a middle aged man noticed there was musician playing. He slowed his pace, and stopped for a few seconds, and then hurried up to meet his schedule.

A minute later, the violinist received his first dollar tip: a woman threw the money in the till and without stopping, and continued to walk.

A few minutes later, someone leaned against the wall to listen to him, but the man looked at his watch and started to walk again. Clearly he was late for work.

The one who paid the most attention was a 3 year old boy. His mother tagged him along, hurried, but the kid stopped to look at the violinist. Finally, the mother pushed hard, and the child continued to walk, turning his head all the time. This action was repeated by several other children. All the parents, without exception, forced them to move on.

In the 45 minutes the musician played, only 6 people stopped and stayed for a while. About 20 gave him money, but continued to walk their normal pace. He collected $32. When he finished playing and silence took over, no one noticed it. No one applauded, nor was there any recognition.

No one knew this, but the violinist was Joshua Bell, one of the most talented musicians in the world. He had just played one of the most intricate pieces ever written, on a violin worth $3.5 million dollars.

Two days before his playing in the subway, Joshua Bell sold out at a theater in Boston where the seats averaged $100.

This is a real story. Joshua Bell playing incognito in the metro station was organized by the Washington Post as part of a social experiment about perception, taste, and priorities of people.

The outlines were: in a commonplace environment at an inappropriate hour: Do we perceive beauty? Do we stop to appreciate it? Do we recognize the talent in an unexpected context?

One of the possible conclusions from this experience could be: If we do not have a moment to stop and listen to one of the best musicians in the world playing the best music ever written, how many other things are we missing?”
