Wireless 3D in HD

HP launches a device called HP Wireless TV Connect, a wireless signal transmitter, which can transmit a 2D or 3D signal via radio to our television.

People who would like to use a computer as a movie player and have a TV in a second room and do not want to pull long cables may have a different solution. HP’s recently introduced HP Wireless TV Connect.

This is a wireless signal transmitter from a PC, connected to a TV via HDMI. This way you can broadcast 1080p signals in 2D or 3D and broadcast it from your computer to watch on our large TV without any visible delays.

The winning photo of the World Press Photo 2013 competition has been redone or not?

If you look at the picture that won this year’s prestigious World Press Photo competition you had the impression that something was seriously wrong with him, you were right. Indeed photography was retouched in Photoshop. Is the degree of its reworking a serious shadow on credibility?

The author of this photo is Paul Hanen, who claimed to have been made on 20 November last year in Gaza, when Israeli troops responded to the attack by the Palestinians. The photo shows two victims of the attack carried to a funeral.

Looking at this picture, however, it is possible to get the impression that it has been retouched because it is unnatural. The service proves that the photo actually consists of three overlapping photos, which in addition have been redesigned in Photoshop.

After careful analysis of the file, unnatural lighting was observed, which would not have been possible under normal conditions, and no artificial lighting was used. Shadows also do not work as they should, taking into account the time of shooting and the position of the sun.

It is said that the photo could be taken in serial mode, then some of them were combined and retouched. Of course, the situation presented in the photo took place, but the photograph itself was purposely redone, which in the case of World Press Photo competition is unacceptable.

The photographer denied that he manipulated the awarded work.

ESA is planning a manned moon journey by 2020

Plans of space conquest, which have been put on the shelf for many years, are beginning to be realized again. The European Space Agency has just announced its latest project, which is sending people to the moon. It will be implemented jointly with international partners, and the goal is scheduled for 2020.

After a long break, the man will reappear on the moon. The European Space Agency has just announced a plan to send man to the surface of the Silver Globe and is planning to do so by 2020.

The project will be implemented in cooperation with international partners and is to consist of a series of manned missions to be sent to the Moon at the end of this decade. Of course, before a human again (or as some claim – for the first time) will set foot on the surface of the Earth’s satellite, there will first be sent robots, which will work to slash the trail and supplement the scientific data of this celestial body.

ESA plans to send mechanical explorers there and devices such as rovers, telephones, and hybrid equipment. Some of them will be used to collect samples on the surface of the planet, while others will help astronauts when they reach their destination.

New Virgin Galactic ship tested

The Virgin Galactic consortium, led by Richard Branson, has just conducted the first VSS Unity test, also known as SpaceShipTwo. The test ended successfully.

Virgin Galactic found that the construction of aircraft was not easy. In 2014, during the test of the SpaceShipTwo ship, he suffered a crash during which his crew died. For the consortium, it was undoubtedly a huge blow that undermined trust in the company and caused retreating customers willing to pay gigantic money for the opportunity to travel to orbit.

Richard Branson did not surrender after this tragic event, and his engineers immediately began designing a new version of SpaceShipTwo. The ship called VSS Unity has just made its first flight. The test lasted only 10 minutes, and during the flight the machine did not accelerate above Mach 6, soaring at 15 km. However, engineers were sufficient to gather data showing how the ship behaves under real conditions.

Photovoltaic cell as light as a feather

The world is increasingly willing to switch to renewable energy sources, and photovoltaic cells are the most common way to produce them. In the near future, it will be even more popular, thanks to a new type of cell developed by MIT engineers.

Fossil fuel resources are shrinking rapidly, so individual countries are investing more and more money in the production of renewable energy, water, wind and sunlight. The most popular method is the latter, but the technology of photovoltaic cells leaves much to be desired and there is plenty of room for innovation.

One of such innovations was demonstrated by MIT engineers and can contribute to the development of mobile devices, various types of electronic sensors, They have succeeded in creating a photovoltaic cell that is thin, flexible and extremely light, so that they can be placed practically on any surface. To show how much this cell is lightweight, the experiment was put on a regular soap bubble without destroying it.
