track a cell phone

In the summer of 2016, Topher White first visited the rainforest of the island of Borneo, in Southeast Asia. At that time there was not more than a tourist, as he says, visiting a protected area for Gibbons, a species of primate. "Above all, I was impressed the overpowering sounds of the forest", he recalls. "There was a constant cacophony of noise. That most stood out, however, was one that I couldn't identify at that time. A sound, whose presence nobody had seen it out of the place". It was a chain saw.

Illegal loggers cut down trees, without permission from the authorities, in the middle of the reserve of the Gibbons, only two kilometers away from the place where he was White. And no one listened to him. This was the trigger of an innovative idea: why not use old mobile phones to monitor the forest? "Mobile phones are excellent, they are full of sensors," says White. "And every year hundreds of millions are thrown away." Among the many sensors that are integrated into a mobile phone, there are sophisticated microphones and GPS tracking systems.

Phones could easily be mounted at the top of the trees. From there they would recognize and identify the noise of chainsaw like a musical application, such as for example Shazam, which recognizes the song that is playing. Then the phone could activate the alarm to the authorities and as it is equipped with GPS, Ranger would know exactly where to look for the illegal loggers.
But a moment: How can a mobile phone to alert anyone in the middle of the jungle? "The big surprise was to discover that we had coverage in the middle of the forest," says White. And that, "we are talking about areas that are hundreds of kilometers from the nearest road", he clarifies.

As so many other founders of emerging companies, or startup, White locked himself in the garage of her parents and began to tinker. He developed software and built built water resistant protective covers to protect the small computer weather adversities. But he soon discovered that the real challenge was to cater to mobile phones with electricity in the forest.

The immediate option was to use solar panels, but through the dense undergrowth of the forest penetrates very little daylight. In this way, White is came the idea of removing all unnecessary components that consume energy of the phone, including displays and speakers. In addition, developed a design with solar cells arranged around the mobile phone like petals of flowers.

Currently, White has transformed their effort in an NGO, Rainforest Connection, and has launched a successful campaign on Kickstarter, which to date has raised more than 150,000 dollars (140,000 euros). In addition, it receives tons of old gift of smart mobile phones because people like to donate their old devices for a good cause.

The first test of the system, on the Indonesian island of Sumatra, was satisfactory. In it, they surprised a group of illegal loggers in the Act, that cooperated without resistance and peacefully left the scene without returning back to the same.

With much support from environmentalists and volunteer groups, the Organization Rainforest Connection has since installed a system in Cameroon and is currently working on the implementation of another in the Brazilian Amazon. All this only it has been possible because of the fascination which caused him to White those sounds of the jungle in his first trip to Borneo.

Nuclear weapon

In dialogue with Infobae, from Jerusalem, Professor Hanoch Gutfreund, current director of the Einstein archive at the Hebrew University of Jerusalem (UHJ); He explained that: "the important thing is to understand that the discovery of Albert Einstein's General theory of relativity had difficult times, highs and lows, including errors, and that is precisely what builds it is so great".

The brilliant mind of this German fisico-teorico of Jewish origin named Albert Einstein, on November 25, 1915 presented to the Prussian Academy of Sciences Research that was going to change forever the way we understand the idea of space-time.

To formulate it, Einstein used reasoning and mathematical deductions, and hypothetical experiments, without a pilot basis. His equations also allowed to deduce testable phenomena.

His presentation in 1915, "had a great impact and definitely became the most famous scientist in the world," confirmed Infobae Professor Gutfreund.

On May 29, 1919, Arthur Eddington measured during an eclipse, the deviation of the light of a star passing close to the Sun. One of the predictions that predicted the manuscript of the General theory of relativity. Until the day of today, theory has been tested in all experiments and checks carried out.

It all started a decade ago when the Professor Einstein, as he liked to be called, he realized that could violate a fundamental physics principle: that bodies fall at the same speed, regardless of its mass and shape.

Added the director of the Einstein Archives Professor Hanoch Gutfreund to Infobae: "I think that the most important feature of Einstein, and allowing him to see and what others did not do was their courage and daring well understood;" against the establishment. Somehow some "lack of respect" toward the authority. He had his own way of interpreting what investigating and was not deterred, nor discouraged by perceptions and vision of the giants of the science of the time. That made it distinct".

The difficult task of being a genius
Albert Einstein was born in 1879 in the city of Ulm, in the North of Germany, in a Jewish family - agnostic. From a young age and especially during his tenure with the Polytechnic of Zurich, in Switzerland, obsessed him the deep underlying connection between gravity and acceleration.

Throughout his life, Einstein had three nationalities: German original; and at age 16 to avoid military service renounced their citizenship of origin and started the paperwork to become naturalized Swiss.

Before the rise of Nazism, he moved to the United States, where he also sought U.S. citizenship, which was granted in 1940, at the age of 61.

The genius label won it when showed, that for himself was his most brilliant idea: the equivalence principle, according to which the inertia force equals - by all means - the attraction of gravity. Forces that are familiar to the ordinary mortals, because gravity "binds us" is the planet and inertia appears suddenly as a response.

In 1915 deduced the equation of physics known by the general public: the equivalence between mass and energy, E = mc². That year published other works which laid the foundations for physical statistics and quantum mechanics. The equation had defied the law of gravity of Newton.

Mount Scopus, its place in the world
In Jerusalem, opened on April 1, 1925 - the same day that Einstein came to Argentina; rose erected on biblical Mount Scopus, the favorite place in the world of the scientist, the Hebrew University of Jerusalem (UHJ).

A group of notables of the era was founded in 1918: the physicist Albert Einstein; the philosopher Martin Buber, Sigmund Freud and the Nobel Prize in chemistry and first President of the State of Israel, Jaim Waizmann. Currently at the top of the podium, regarded as one of the centres of excellence in the world scientific knowledge.

Nasa informations

NASA is looking for candidates willing to work in the space. It is not a common job offer, but so. United States Aerospace Agency has opened a period of time, which started Monday and will end on February 18 next year, to recruit applicants among U.S. citizens who want to join in some of the most exciting projects that humanity has ahead. Among others, the desired trip to Mars. "NASA is preparing an ambitious journey to Mars and we are looking for men and women with talent from different fields to help us get there," said the administrator of the Agency, and former astronaut Charles Bolden.

U.S. citizens wishing to post will have to go through a thorough selection process which will last several months, since both physical and academic demands for such work are enormous. In fact, the names of the elected members not know until the spring of 2017. And will not be until the autumn of that year when begin to work of truth in his new career center: Johnson Space Center, in Houston. Final testing includes personal interviews with qualified staff from NASA that will give the final verdict.

Applicants must have, essentially, studies of Science: engineers, mathematicians, physicists or biologists. The Agency officials also value the fact that the candidates have experience as pilots of aircraft. NASA estimates that about three million Americans meet the basic requirements to aspire to be part of the new generation of astronauts.

Along with the challenge of Mars, NASA says, as incentive, those selected will travel to the international space station, in which years cooperate the United States and Russia; two spaceships that built American businesses or new exploration vehicle space Orion, which was launched into space on an experimental basis just a year ago and hoped that in 2021 can be already manned by astronauts. The elect will go through testing in the orbit of the Moon, where they will learn complex spatial operations before moving on to the main objective, as it is the mission to Mars.

In your job offer, NASA remembers that today are developing more aerospace projects that never in history and that future candidates will have the opportunity to meet the space areas never explored by humanity. So far, NASA has made a selection of more than 300 astronauts to explore space. And many more are needed for future missions to the international space station, where he held various research and new technologies are tested. NASA warns that the missions on the space station last between three and six months and that the preparation to be so long in space requires a period of preparation of two to three years.

If a civilization intercepts Voyager and can understand these recorded contents, here is our message: this is a gift from a far and distant world. A compendium of our sounds, our science, our images, our music and our thoughts and feelings. We are attempting to survive our time so we may live into yours. We hope that someday, after solving the problems that we face, we can join a community of Galactic Civilizations. This record represents our hope, our determination and our goodwill in a vast and awesome universe." This is the letter written by President Jimmy Carter in which presents to mankind in anticipation of possible extraterrestrial encounter. People drinking from a jug, frogs, a man pulling her skin to a crocodile, binges, the great wall of China and the Taj Mahal are some of the images that accompany the Intergalactic lot involving Nasa on the Voyager ships launched into space beyond the solar system in 1977.
