Such interesting phenomenon as superconductivity was discovered by the scientist from the Netherlands H. Kamerling-Onnes in 1911 when scientists in scientific labs learned how to boil down temperature to "absolute zero" synthetically, i.e. to the temperature which prevails in space. Certainly, two years later the Dutch scientist received the most prestigious award on physics for such discovery - the Nobel Prize. The next breakthrough in science and engineering in this area was made by physicists working in Zurich in 1986 – the Swiss A. Müller and the German G. Bednortsa who received the Nobel Prize a year later. They excelled their Dutch colleague having managed to achieve a superconducting condition at a much higher temperature which made superconductivity more accessible for people. It also holds out a hope of such phenomenon being possible at even more higher temperatures.
As superconductivity was achieved at a temperature of -269 C° in 1911 and at a temperature of 196 C° in 1986, the superconductivity phenomenon was divided to low-temperature and high-temperature. Certainly, it is relatively, as a matter of fact the atmospheric temperature doesn't fall lower 50-60 C° in the coldest canton even in the coldest winter.
Along with discovery of superconductivity phenomenon and its research, scientists discover more and more new alloys of metals which can lose resistance. The further development will allow using other, cheaper and more accessible metals which will make such remarkable phenomenon as superconductivity more accessible and will allow its’ coming into our everyday life.
