3 September 1976 landed on Mars lander spacecraft module “Viking-2”. Just under the campaign, there were two flight. About the program “Viking” we wrote in one of the previous “days in history”.
Space module “Viking 2” was launched 9 September 1975. After 333 days the unit started to send General images of Mars to Earth. In orbit, he was released on 7 August 1976. The main objective of “Viking-2” was to study the soil of Mars. As a result of researches it was proved that the surface of Mars resembles basaltic lava, subjected to erosion. In soil composition and large amounts of iron and silicon. Also dominated by magnesium, aluminum, calcium and titanium.
The lander operated on the surface 1281 Martian day, until 11 April 1980. Connection with the “Viking-2” was interrupted when out of order the battery.

On 3 September 2005 was presented the first silicon quantum chip. Distinguished team Hitachi, who worked at the time at Cambridge University in the UK. As you know, quantum chips record information not in the form of all the usual stress levels, but in a quantum bit — the qubit.
Here dwell. If the “classical” bit — unit of information — is encoded by two strains, indicating “zero” and “unit”, then the qubit writes the data as an arbitrary superposition of two quantum States, also corresponding to the “zero” and “unit”. Thus, in one quantum bit can contain much more information. In theory, an infinitely large amount of information. Plus for qubits characterized by the so-called “confusion” when operating on a single qubit changes the wave function and the state of the second qubit.
Scientists from Cambridge University have managed to produce all the basic operations, that is, not just to create a qubit: the “initialization” — recording the quantum state of a qubit; “manipulation” and “measure” — the final quantum state.
Earlier quantum bits had been create on the basis of gallium arsenide, however, so-called time of dekogerentsiya (the period during which the stored state of a qubit) has been extremely small. The working group of Hitachi, using silicon, were able to increase this feature 100 times.
In 2011 was created the world’s first quantum processor target. This time tried scientists from the Centre for quantum Photonics University of Bristol. Chip is a model generated from multiple electrodes and waveguides made of silicon dioxide. The quantum state of a qubit in such a device, reproduced with the help of the programming electrodes. Just the CPU area 3х70 mm, there were two qubit.
It is believed that quantum processors will replace the classical semiconductor technologies. It remains to be seen exactly when this will happen. Moore’s law, announced more than half a century ago, is still in effect.

September 3, 2014 at the exhibition IFA was submitted to the phablet Samsung Galaxy Note 4. The device proved to be very successful. For example, according to resource AnTuTu, Galaxy Note 4 is the most popular Android smartphone in 2015.
The phablet has got a 5.7-inch screen with a resolution Quad HD (2560×1440). Matrix — Super AMOLED, which is characterized by bright, vivid colors. The basis Galaxy Note 4 is the eight-core Samsung Exynos 5433 processor with a clock frequency of 1.9 GHz and 3 GB of RAM. But the built-in — 32 GB. In the presence of a Micro SD slot that supports memory cards up to 64 GB.
As for cameras in the smartphone, the mainstream resolution has increased (in comparison with the Galaxy Note 3) from 13 MP to 16 MP. Plus, the module has acquired a new feature image stabilization — Smart OIS. The front camera has a resolution of 3.7 MP.
