Japanese scientists ISOMO Akasaki Hiroshi Amano and Shuji Nakamura received the Nobel Prize in Physics. This year’s winners have developed energy-saving and environmentally friendly source of light – blue light emitting diode.

The new light that illuminated the world – that the Nobel Committee described this year’s prize in physics.

The Committee appreciated – as the explanatory memorandum – the invention by scientists efficient blue light emitting diodes, which allowed for the creation of clear and efficient sources of white light . Their inventions were revolutionary. Bulbs lit the twentieth century; XXI century illuminate LEDs – wrote the members of the Nobel Committee. In their view, this can improve the quality of life of 1.5 billion people worldwide without access to electricity. Thanks to low-energy blue LEDs can be powered because cheap sources of energy, for example. Solar panels.

The light-emitting diode LED very efficiently convert electricity to light. They are much more durable than incandescent or fluorescent lamps. Unlike fluorescent lamps, can be quickly and frequently switched on and off, without harm to the sustainability – and do not contain poisonous mercury.

The theoretical basis of the LED built in the early twentieth century, but in the practical application had to wait yet decades. At the end of the 50s there were red LEDs, later developed as green. Found use as a display element in watches and measuring devices and indicating lights connect to the network. But for 30 years failed to create a blue LED, which is necessary to build a LED lamp emitting white light – the combination of colors: red, green and blue.

Awarded Nobel laureates are real fame in the scientific world. In the 90s, Isamu Akasaki Hiroshi Amano, and Shuji Nakamura made a real breakthrough in lighting technology. The semiconductor light-emitting diodes for the first time gave a clear blue light. Work on it continued for over 30 years.

In the past year the prize in physics was awarded Briton Peter Higgsowi and Francois Englertowi (Belgium), the theory explains how to take the weight. The correctness of theory confirmed the discovery in 2012, the Higgs boson, also known divine particle . The work of Nobel Prize winners completed the theory called the Model standard.

yesterday awarded the Nobel Prize for medicine and physiology. It was awarded to three scientists who have conducted in the UK pioneering research on the so-called. internal GPS. John O’Keefe and the marriage of May-Britt and Edvard Moserowie shared the trophy for the discovery of cells that make up the positioning system in the brain .
