Galaxy S7

Galaxy S7   

Despite rumors of increasingly detailed next top smartphone from Samsung, Galaxy S7, Korean company refuses to speak publicly about this model. All signs lead to an announcement at Mobile World Congress 2016 where you probably have this year there is a new conference "Unpacked" but the launch itself might be very close to this event.

It seems that Samsung will keep the Galaxy S7 disclosure event just two weeks away from the ad itself, which is expected towards the end of February. According to Evan Blass (evleaks on Twitter) that often provide accurate information about smartphones before they are announced, the launch of the United States for the new Samsung flagship will be Friday, March 11. If this date coincides with the global launch, it is quite difficult to guess right now, but Samsung, like other companies in the industry, launching new smartphones in more waves, so 11 March should be valid in several regions.
Galaxy is expected in two versions S7 hardware, chipset Exynos chipset in Snapdragon certain regions and others. The new Samsung smartphone could be delivered in three variations: normal, with display of 5.1 "and display flat edge S7-screen 5.1" curved edge S7 + curved screen of 5.7 " . According to the details available at the moment, all will have 4 GB of RAM.

An alleged employee of Samsung revealed some information about Samsung Galaxy Samsung Galaxy S7 and S7 Edge, they must convince the world that the new terminal will come with major changes this year. Samsung Galaxy S7 will have a screen diagonal of 5.1 inches, while Samsung Galaxy S7 Edge will have a screen diagonal of 5.5 inches, this information is already confirmed again during the day, so it's unlikely that Samsung change something. What new ad alleged employee of Samsung is the Samsung Galaxy S7 will have a 12 megapixel camera instead of the 16 megapixels used in Samsung Galaxy S6, it will have an aperture of f / 1.7 to take pictures very good night. Samsung will present Samsung Galaxy S7 as a terminal capable of recording great pictures at night, use a lower chambers representing apparently wish Samsung to provide better quality camera and not more megapixels, a technology focus dual pixel being Implemented, the devices being used in Canon DSLR.

In an event where he announced plans for next year, the Chinese company submitted a graph on product launches, and among these is the Galaxy S7 scheduled for March. Interestingly, China Mobile announced new smartphone price - 465 dollars.
The information come to confirm what we already know - that South Koreans Samsung Galaxy S7 will present on February 21 at the Mobile World Congress in Barcelona, ​​so that the launch will take place in stores in March.
Regarding the look of the new phone codenamed G930F SM and SM-G935F (S7 Edge Galaxy variant) recently reported that after being criticized for S6 and S6 Galaxy phones fragility Edge, fully covered with glass South Koreans seem to have finally understood the message that the phone is not a toy and that the utility must be in the spotlight!
So, with the new Galaxy S7 and S7 Edge, the company will adopt a magnesium housing that will cover the back of the phone, which will make it more resistant to drops and scratches.
Samsung Galaxy S7 will be available in two variants of processors, own one - Exynos and Qualcomm Snapdragon 8890 820. We will be available at the Exynos according SamsungGalaxy site.
The processor octa-core Exynos 8890 has four cores 64bit ARMv8, and four Cortex A-53 which together deliver better performance with 30% the previous version, Exynos 7420, present on Galaxy S6 and Note5.
And energy consumption is lower by about 10%.
New technical solution developed 14 nm, enables download speeds of up to 600Mbps and upload speeds of about 150Mbps, thanks cat.12 modem / 13 and ARM Mali-T880 graphics card MP12 provides unprecedented multimedia experience.
According to the Wall Street Journal, the smartphone will allow South Koreans phone via microSD memory expansion, such a slot will be present on the phone.
Journalists notes, on the other hand, the Galaxy S7 will be the first Samsung phone that will include a 3D type Touch technology which, depending on how you press the screen will send different commands.
Innovation, prevetată Samsung in South Korea, is similar to that used by Apple but promises to take the user experience to a higher level by associating with a number of Android applications.
Samsung Galaxy S7 will have a new room, 16 MP, which will provide unprecedented image quality, thanks to technology Britecell.
The new chamber will include sensors Britecell less than one micron that will allow South Korean reduce its size by up to 17%, and thus enabling the development of mobile and thinner.
Essentially, Britecell will replace the traditional RGB pixels with some green white and the room will attract more natural light and reduce thus considered artificial colors.
Otherwise, S7 and Samsung Galaxy Samsung Galaxy S7 Edge will have 4 GB of RAM and a 64 GB storage space.
The new smartphone Galaxy S7 will be the first in the series that will include electronic e-SIM card solution technique that would become the new standard in the field. E-card, already available on the new iPad allows users to change mobile phone operators without having to change the physical card and phone.
Beyond these features, the new Samsung Galaxy S7 would revert to standard IP68 and is resistant to water and dust, and include a new solution for optimizing battery Superfast Graphene, which will charge your phone in 15 minutes!
To wait and see whether or not Samsung will rise to expectations regarding specidicatiile S7 model. Please visit this site occasionally to read the latest news about the release date of Samsung S7.

Astronomers have conducted a detailed study of a cluster of galaxies very young and very massive, IDCS 1426 using three observatories NASA in visible light with Telescope orbital Hubble, infrared Spitzer Space Telescope, respectively in X-rays by Chandra x-ray Observatory. The result is this picture of the three observations made up of pictures taken from three observatories.

This rare galactic cluster, located about 10 billion light years from Earth, has a mass equivalent to an estimated 500 trillion suns. The study of this cosmic object can provide important information about how such Megastructures formed and evolved during the heyday of the universe. This composite image of galaxy cluster IDCS 1426 dates when the universe was less than one third of its current age, or about 3.8 billion years and 1426 is the IDCS massive galactic cluster or clusters detected during this period of youth Universe.

Discovered by the Spitzer Space Telescope in 2012, 1426 IDCS was then observed through the lens telescopes Hubble and Keck Observatory in order to determine the distance at which it is located. The first observations carried out indicated that it is an extraordinarily massive galactic cluster. New data obtained by Chandra X-ray Observatory have confirmed the mass of this cluster galactic and led to the conclusion that about 90% of this mass is the fact dark matter - the mysterious substance that has not yet been detected directly, but only based on the gravitational influence it exerts on ordinary matter, made of atoms.

Near the center of the cluster is a region in which X-rays are emitted very bright (in blue and white), but not in the center of the swarm. The location of this core cluster suggests that cosmic gas would have collided with another massive system of galaxies relatively recently, probably when the age of the universe was only 3.3 billion years. This core of gas, although in turn extremely hot, it contains gas cooler than the surrounding areas. Observing a core of gas so "cold" in a galactic cluster so far, is again a first.

Astronomers believe that the study of such core "cold" is important to understand how quickly they lose heat from hot gases such swarms, a phenomenon that affects the rate of fire of new stars. This cooling rate can be slowed and action supermassive black hole in the center of the swarm.

I started my career as an intern at NASA. I've worked at several companies in Silicon Valley. In fact, I gave in 1986, an interview with Pixar, but I went to them. I accepted another offer. After a few years, I thought things were not what I wanted them, so I came back. I kept in touch with them. Initially, I was hired to work with their software. RenderMan take care of a plug-in compatible with major 3D animation software platforms, McCoy told AFP, adding that he began to develop his artistic skills when he had to work with photos.
I joined the team early enough to travel to Paris "joked McCoy. The food is difficult because people are so constructed that detects whether or not the food looks delicious. We did eat in our films. For example, in The Incredibles "family dinner. If you look closely, that food is not that great, but it was subject. But the people watching Ratatouille food and delicious dish should look. I said, 'Wow, I've never done anything like this before. We had practically to make food look alive. Most times, you are told to do something look nice, but sometimes you are asked to do something you look more delicious.

Why are round windows of the plane?

Why are round windows of the plane? It took two crashes to understand why
   One of the questions we have all asked when we embarked on an airplane commercial passenger was certainly linked to the porthole shape. Why is rounded, not square? Is it design or engineering has reason? The answer is very simple and fascinating science behind it.

First, square portholes were at the beginning. As a result of technological advances, increasingly planes flying above, where there is less turbulence, but where necessary to pressurize the interior. The differences in pressure, the metal fuselage expands and contracts, which greatly stress the material around windows, which disrupt blood, enhancing it.

Unfortunately, the two crashes were necessary for scientists to understand what caused them. All aircraft that were made after these accidents were equipped with portholes rounded to protect the integrity of the fuselage. The same principles were applied and portholes for cargo aircraft and space shuttles.

Perhaps you've wondered about the hole inside the glass, if you've seen before. Again, it's about regulation of blood pressure and the pressure that accumulates between the outside and the inside. Each window is made actually three layers, and the hole allows the air pressure between the outer layer and the middle to balance.

After Skreemr concept, Bombardier Charles amazes with a new invention of aircraft capable of reaching Mach 24, 12 times faster than Concorde. Although only ten people can carry, crosses over 20 000 km in less than 60 minutes.

The aircraft "Antipode has the ability to cross over 12 430 miles (20 000 km) and can be reached from London to New York in just 11 minutes.

Such flights operated with a magnetic rail system to effectively catapulted into the air, reaching Mach 10. The aircraft is placed on parallel conductive rails launching device using a magnetic field particularly strong. As a backup system, the aircraft could use some additional rockets which works with liquid oxygen and kerosene, helping plane "Antipode" to rise as much and achieve Mach 4. In turn, the aircraft engines impressive would it One could propel at speeds ten times faster than that of sound (12 349 km / h).

Flight problems this concept as the deafening noise that would be sent to the earth and the enormous heat that emits a release. This can however be reduced by using a LPM ("long penetration mode") that will reduce the extremely high temperatures of launch and the shock wave.

For now, the aircraft is intended for military and business environment, being transported in an extremely short time and very far two officials of States for example.

The announcement was made by Deputy Minister of Transport of Iran, Abbas Akhoundi quoted by Iranian media, the daily Le Figaro informs, quoted by Mediafax. During the visit the President of France, will be signed for the purchase of 114 Airbus said Akhoundi without providing details about favorite models and value the agreement. The Minister also said that Iran needs 400 aircraft for long-haul and medium and 100 devices for short distances. Iran currently has 256 aircraft, of which 150 are operational, operating with an average of 20 years.
