How to see who is calling from that unknown phone number

How to see who is calling from that unknown phone number
Getting a phone call from a number you don't recognize can be annoying. Sometimes you simply don't know whether you should pick up or not. Is it the National Weather Service calling to inform you that they chose the name you submitted for the next hurricane, or is it a debt collector that wants to know what you are up to? Or perhaps just a friend who switched to a new number?

There are reverse phone lookup web sites that can be of use in such a case, and WhoIsThisPhone is one of them. The service has been online for only a few months, yet over 1.3 million queries have already been processed.

treasure of Agrihan

The lost treasure of Agrihan Island

In 1817 there was a Scotsman by the name of Roberton. He was a pirate who worked for the Chileans in the fight against the Spanish. He was known not only for his ghastly sight, which was of average height and shocking red hair, he was also known for his cruel and torturous ways. A couple of years later, a bandit known as Benavides appeared and began to stir up real trouble. Roberton took as his prisoner a friend of the bandit and demanded to know where Benavides was. Remembering Roberton’s reputation, the friend told him where the bandit was hiding.

Robertson gathered up an army of men and went to catch Benavides by surprise. While Roberton and his army were successful in capturing all of Benavides’ men, Benavides himself escaped. Roberton first extracted further information from these men and then proceeded to hang all sixty of them. The information he retrieved from them before their deaths was that they knew of gold that was buried on an island just off the coast of Chile. The island was called Mocha. Roberton took his brother and some other faithful followers and moved to the island. One day while they were returning from Valdivia, they ran into trouble and all but Roberton drowned. Roberton had no desire to live on Mocha without his men and so he joined the Peruvian Island. He never gave another thought to the buried treasure that was never found on Mocha Island.
While fighting against Lima, he was captured and taken prisoner by them. They soon let him go and he returned to Peru where he met Teresa Mendez. Teresa was a young woman of 21. She had been married once before and had lost her first husband at sea. She was almost as wealthy as she was beautiful and had many admirers but she really only ever paid attention to the ones that had wealth and came from an upstanding background. Roberton was not wealthy and his family was small and unknown. But he was desperately in love with her and persisted in his attempts to persuade her to love him too. His pleas were always met with a laugh until one day she told him that if he could promise her a life of wealth and luxury, she would marry him. Nobody believed that she would fulfill her end of the promise.
It was during the same time that the ship Peruana was docked in the harbor. One night during a meeting between the officers, Lieutenant Vieyra laughed and suggested that Roberton rob the ship, which held over two million pieces of gold. Then he could take the treasure and show it to Teresa to win her love. That same night Roberton collected a few men who were mostly British. The Peruana did not have very good security and so it was easy to attack the few guards and sail away with the ship and the treasure she held. When morning came, there was no sign of either.
Roberton took his men to Tahiti. He knew however that they could not stay for although they had many hours on their opponent, people would come looking for them. He and two most trusted followers, George and William, agreed. The rest of his crew did not want to leave Tahiti at first and so Roberton also took aboard fifteen women. The men followed shortly after. While the women may have gotten the men back onto the boat, Roberton knew that it only gave him more people he had to get off. The treasure had always in his mind been for him to share with Teresa. His crew and the women would have no part of it. As he started to sail towards the Mariana Islands, he declared that eight of the crew were trying to take over the ship. He ordered that they be left on a deserted island as punishment and continued on to Agrihan Island.
Once on the island, Roberton began to slaughter the women. William, who was very good with a weapon, began shooting them. After all of the women were killed, the remaining seven members of Roberton’s crew loaded the treasure onto rowboats and rowed safely to shore. They found a spot located at the bottom of a cliff and began to dig a hole for their treasure. They then placed their treasure in the hole and covered it up, leaving tree branch markings as a sign of where it was buried. They had kept 20,000 gold pieces for extra money along the way and locked the other members of the crew inside the ship. Using one of the rowboats, Roberton and his crew swam to shore and pretended to be shaken about the terrible shipwreck they had just been in. They talked of how they were the only survivors. What they didn’t know was that their ship hadn’t sunk before one man escaped. The other three had starved to death and it had taken him a year to make it back but he was still alive.
From there, George left the other two to go to Rio de Janeiro. Roberton and William continued to travel together though and wanted to go back to retrieve the treasure they had buried. They began the travel back to Agrihan and stopped in Hobart, Tasmania, where they met Thomson who was a sailor. They quickly convinced Thomson to get a crew together and take the two of them north. After a long night of drinking one evening, William told Thomson the entire story. Not being able to remember the name of the island exactly, Thomson concurred from his description that it must be Agrihan. Not many nights afterward, Thomson was woken up by the sound of William’s screams. Going to check on the problem, Thomson found him murdered. After this, Thomson knew what to expect from Roberton and was very careful around him. However, he was simply not as strong as Roberton and the latter pushed him overboard.
Although he was near-dead when he was rescued, Thomson was found by a Spanish ship and taken aboard. After telling his rescuers his story, they began to aggressively pursue Roberton. Roberton meanwhile, was sailing to Spain so that he could seek refuge in the mountains and hide for awhile. However, the Spanish found him and took him to Agrihan so that he could tell them where the treasure was. But Roberton would not tell them. Instead, he kept trying to escape.
They took him back to their ship and using other forms of torture such as whips, demanded that he give them more information. He finally agreed but as they were taking him back to the island to show them, he jumped overboard, with his chains still around his feet. He quickly sank to the bottom and never saw Teresa again. The Spanish continued for some time to find the treasure but always came up empty-handed. It’s thought that the treasure is still on this island today.

 

Music and Creativity

                                                                    Music can spark creativity in math and science

From records to boom boxes to CD's and iPods, music has long been part of the lifeblood of being a teenager. Learning math and science in class is not always such a priority.
Parag Chordia, director of the Music Intelligence Lab at Georgia Tech, is finding ways to bring those two disparate realities together.
"How can music be used to think about scientific problems, how can music be used to sort of catalyze our thinking in other areas?" asks Chordia.
With support from the National Science Foundation (NSF), Chordia is researching the neurological roots of the creative process. And music is a key ingredient.
"We've never found a culture that has no language--we've never found a culture that has no music. So, music seems to be universal," he says.
While music and arts programs are often the first subjects to be cut when school budgets are tight, Chordia says that may not be the best strategy.
"To be a great engineer; to really produce innovative products and to advance the frontiers of science, you have to be creative. And it's not just that music is a diversion or an extracurricular, but it's actually something that's fundamental to life and mind," he says.
"One of the difficulties of teaching math and science is that it quickly becomes very abstract. You have to have points of reference that people can relate to and it becomes much easier. So, whether we're talking about teaching basic mathematical concepts, or designing experiments, you can design experiments around music," he explains.
Statistics, for instance, can be used to model music.
"For example, if you listen to a melody, a melody is made up of all these different little motifs, and those motifs go together to make up larger patterns and those larger patterns form bigger blocks that we build on," says Chordia.
"So it's very similar to language, where you have these low level acoustic units like phonemes, which form syllables, which form words. So, what we are trying to do here represents that process of pattern formation," he says.
Studies show that at different ages, music connections do work as teaching tools.
"At the college level, students who have access to music programs are much more likely to graduate because it increases retention," says Chordia. "And people have, in terms of early learning, shown that exposure to music at an early age, intensive exposure in music does improve cognitive outcomes."
Chordia understands the creative process from many angles. He is a master of the sarod, a classic Indian instrument. He is also a mathematician. And his research works to see how all those elements work together.
"Is creativity just the gift of a few--just sprinkled on a few people and that's it? I would argue no, that creativity is something that we all have inside of us and what it's all about is finding out, how do we unlock that creativity," he says.
Using tools like electroencephalograms (EEGs) and functional magnetic resonance imaging (fMRI), Chordia is investigating whether "real-time creativity," like improvising in a jazz band, uses the brain in a different way.
"When a person is improvising, are they entering into a uniquely creative state, and if so, what is that state all about?" he asks.
Brain scans show a distinct difference when professional musicians are playing composed music, versus when they are improvising. Future studies could be designed to try to home in on exactly what is happening when someone is experiencing deep creative insight.
Other work in the Music Intelligence Lab involves music and computers.
Graduate student Avinash Sastry investigates "computational creativity." While that may sound beyond the scope of what we think these machines usually do, the aim is to let computers do what they do best, to free up human teachers and composers for their best work.
Sastry writes computer programs that analyze musical compositions; then, the computers write their own music.
"So we have a database of compositions, giving it [the computer] some idea of what it is going to expect. So it analyzes all this, and builds up this big tree of probabilities. It's going to try and predict what's going to happen at every step and it's going to use that information to try and compose its own sequence of strokes as it goes on," explains Sastry.
Sastry says he has done some double takes when he hears original music composed by a computer.
"So sometimes you get these gems of music that just pop out, and we are working on trying to isolate those things and use that in a more constructive way," he says.
Sastry says he can easily see this as being an educational tool for children, and even musicians. The human composer gives the computer something to start with, and it can then try to help you compose.
"So the idea is to use everything together ... use their computational ability along with our emotions, our ability, our creativity, put everything together and make some sort of collaboration!" says Sastry.
An iPhone app Chordia and colleagues created gives a psychological boost to people who may not think they have any musical skills.
It's called LaDiDa, and it now has more than ten million users.
"You sing into the app, it listens to what you are singing, and it composes music to match. Our goal is to make music expression as ubiquitous as social expression," says Chordia.
"I'm a terrible singer, and I think part of the whole point of this technology is to let people like myself actually get the confidence to make music."
There are many YouTube videos of LaDiDa users, from Chordia himself to Mishka the singing dog, using the simple app, and in most cases, sounding much better after the app's music has been added.
"A lot of the people we are targeting are young people between 13 and 18, who are really engaged in music. And they want to have the experience of making music. We get emails all the time, 'I was afraid to sing but now it makes me want to sing all the time'," says Chordia.
And those musical experiences that feed the mind may also spark greater proficiency in science and technology.
"Creativity lies at the heart of the modern economy," he says.
