Electronics is a field of engineering and applied physics dealing with the design and application of electronic circuits. The operation of circuits depends on the flow of electrons for generation, transmission, reception and storage of information. Today it is difficult to imagine our life without electronics. It surrounds us everywhere. Electronic devices are widely used in scientific research and industrial designing, they control the work of plants and power stations, calculate the trajectories of space-ships and help the people discover new phenomena of nature. Automatization of production processes and studies on living organisms became possible due to electronics. The invention of vacuum tubes at the beginning of the 20th century was, the starting point of the rapid growth of modern electronics. Vacuum tubes assisted in manipulation of signals. The development of a large variety of tubes designed for specialized functions made possible the progress in radio communication technology before the World War II and in the creation of early computers during and shortly after the war. The transistor invented by American scientists W. Shockly, J. Bardeen and W. Brattain in 1948 completely replaced the vacuum tube. The transistor, a small piece of a semiconductor with three electrodes, had great advantages over the best vacuum tubes. It provided the same functions as the vacuum tube but at reduced weight, cost, power consumption, and with high reliability. With the invention of the transistor all essential circuit functions could be carried out inside solid bodies. The aim of creating electronic circuits with entirely solid-state components had finally been realized. Early transistors could respond at a rate of a few million times a second. This was fast enough to serve in radio circuits, but far below the speed needed for high speed computers or for microwave communication systems. The progress in semiconductor technology led to the development of the integrated circuit (IС), which was discovered due to the efforts of John Kilby in 1958. There appeared a new field of science — integrated electronics. The essence of it is batch processing. Instead of making, testing and assembling discrete components on a chip one at a time, large groupings of these components together with their interconnections were made all at a time. IС greatly reduced the size of devices, lowered manufacturing costs and at the same time they provided high speed and increased reliability.

I think I want to travel to Myrmansk. The best way to travel there- take a train. It’s safe and fast way for travel. We can eat there at restaurant- White Rabbit. ITIS very good cafe, there are very delicious food.We can find ar the menu food from all world: sushi, tacos, fish and chips, pourge, and other lovely eat! In Murmansk is very big Ferris wheel! It has many lights, at night Wheel is looks very beautiful. I think I want to take an excursion to waterfall on river Lavla. My friend went there, and he stayed that it was exiting. Murmansk- is very interesting place, I want to go there.
Picasso is a great artist who worked in a 1 variety of different 2 styles, some realistic and others 3 abstract. He developed a wide range of painting 4 techniques. He usually painted using 5 oils, but he liked to 6 vary things and sometimes used 7 watercolors. He loved to paint people and produced a beautiful 8 portrait of his mother. Many people believe that his real 9 masterpiece was Guernica, which he painted during the Spanish Civil War. In the past, the painting was on 10 display in 11 exhibitions all over the world, but it is now permanently in Madrid.
