To know the answer to this question you should know at the outset scientific definition of the word magnet which is simply any material or component of a magnetic field, which is in the range of electrons moving in the same direction, these electrons are always striving to be associated with other electrons. Any magnet has two poles, north and south of the area where the magnet comes out caused by electrons from the North Pole and enters once again across the Antarctic.

If we look at the iron as an example, we will find that it contains many of the electrons of others linked to it in any individual case and therefore magnets When approaching a piece of iron is attracted to him because of the forces of attraction between electrons, which seeks to link and of the magnetic field generated by.

You have to think about these questions .. why some materials are attracted to the magnet and the other is not attracted, and how to turn ordinary materials magnet?

Have you ever wondered how one day one of you is the age of the earth? I think a controversial question was already over the past three centuries past, in 1654 one of the researchers who called John Lightfoot offered to answer this question and said that the earth was created in exactly nine o'clock on the morning of 26 October 4004 BC, based on his calculations on the Bible.

In the seventeenth century the world called the Comte de Buffon heating the sample similar in composition to the ground with making and based on the rate of low temperature by estimating the age of the Earth is about 75,000 a year.

In the nineteenth century, a scientist Lord Kelvin equations and using some of the age of the earth as much as 20 to 40 million years old, and this was the last attempts until it was discovered the radioactivity of the material and its use in determining the age of different materials by measuring the rate of decay. This is the method currently used to determine the age of rocks and fossils and archaeological samples and even samples that come by astronauts from the moon and Mars, and based on that method has been estimating the age of the Earth is about 4.54 billion years margin of error of less than 1%.

Now you can respond to this question .. How old is the universe?

A group of researchers discovered that the blue color in the sky affects our feelings in a positive Vtgalna more responsive and adaptable to the challenges related to emotions, but you may ever wondered why the sky looks blue?

The short answer very lies in a phenomenon called dispersion means the spread of the light falling on an object in several different directions, for we receive the sun's rays must pass the atmosphere of the Earth, which consists of several layers as we all know and has a different set of gases and particles. Collide sunlight those obstacles are scattered here and there, and as we know, rays sun is made up of several different shades of each spectrum has a specific wavelength and thus has a specific color and features a nice blue color wavelength is relatively small and thus easily spread through those obstacles and scattered in the sky, causing those blue that we see .

But you may also be wondering what about the time of sunrise and sunset, where the color of the sky red or yellow or orange? In those times the sun be much farther away from the noon time and age and thus Vohatha travel longer distances to reach our eyes and this affects the advantage of short-wavelength blue color and allows us to see some other colors. Also worth noting that if you look directly to the sun will not only see the white around it for you in this case to consider the sun's rays directly you see in this moment all the spectra and colors combined.

Now you can respond to this question too .. Why do you look the ocean blue?

In the Bosnia and Herzegovina town of Mostar, a local dive club instructor jumps from the Stari Most, or Old Bridge, to the Neretva River below. "Divers have been leaping from the bridge for hundreds of years," writes Chester Boyes, a member of our Your Shot community. "On this day, we were going to try it for ourselves. Here, our instructor shows us how it's done before we try our luck."
Noticing the size and energy of the crowd, Boyes quickly ran down to the river's edge, hoping to catch his instructor in flight. "I arrived just in time."
Boyes’s picture recently appeared in Your Shot’s Daily Dozen.

Four Billion BCE: Battered Earth
Illustration Credit: Simone Marchi (SwRI), SSERVI, NASA Explanation: No place on Earth was safe. Four billion years ago, during the Hadean eon, our Solar System was a dangerous shooting gallery of large and dangerous rocks and ice chunks. Recent examination of lunar and Earth bombardment data indicate that the entire surface of the Earth underwent piecemeal upheavals, hiding our globe's ancient geologic history, and creating a battered world with no remaining familiar land masses. The rain of devastation made it difficult for any life to survive, although bacteria that could endure high temperatures had the best chance. Oceans thought to have formed during this epoch would boil away after particularly heavy impacts, only to reform again. The above artist's illustration depicts how Earth might have looked during this epoch, with circular impact features dotting the daylight side, and hot lava flows visible in the night. One billion years later, in a calmer Solar System, Earth's first supercontinent formed.

Destiny developer Bungie has released detailed stats from the game's beta tests.

The 4.6 million players who took part in the trials are said to have been involved in 88.4 million matches between them.


There were 164 million deaths during the beta and players racked up a combined total of 3.7 billion kills and 62 million revivals.

Destiny fans also created 6.5 million Guardians, 851,264 of which went to the moon.

Furthermore, the Destiny companion app for mobile devices was used by 777,000 players during the tests.


"We're running out of ways to thank you for what the Beta has meant to us. We hope you had fun," said community manager David 'DeeJ' Dague.

"Destiny will be a better game because you played it. Perhaps that's the best gesture we can manage - to deliver a game that's better than it was before your contribution.

"Today is the first day of August. Start the countdown on your last month of waiting. Next month, we'll all start playing Destiny for real."

The full game will debut as part of a white PS4 console bundle on September 9, along with a release on Xbox 360, Xbox One and PS3.

LOUISVILLE – Tiger Woods' latest injury "doesn't bode well right now" for his chances to play in the Ryder Cup, U.S. captain Tom Watson said Monday.
A day after withdrawing after eight holes in the last round of the World Golf Championships-Bridgestone Invitational with a bad back, Tiger Woods doesn't know if he'll be playing in this week's PGA Championship.
Woods flew back Sunday afternoon to his South Florida home instead of heading to Valhalla Golf Club for the year's last major championship after he aggravated his back and was forced to withdraw.
Woods is at his home resting.
"He has to rest and get treatment and assess later," said Woods' agent, Mark Steinberg, in a text. "Pointless to make that decision (on playing) now without proper time to give him the best chance."
