Shuji Nakamura — Japanese Physicist born on May 22, 1954,

Shuji Nakamura is a Japanese-born American electronic engineer and inventor specializing in the field of semiconductor technology, professor at the Materials Department of the College of Engineering, University of California, Santa Barbara, and is regarded as the inventor of the blue LED, a major breakthrough in lighting technology. Together with Isamu Akasaki and Hiroshi Amano, he is one of the three recipients of the 2014 Nobel Prize for Physics "for the invention of efficient blue light-emitting diodes, which has enabled bright and energy-saving white light sources"... (wikipedia)

The LED light bulb is more than ten times the efficiency of regular incandescent lighting, so it can save the world hundreds of billions of dollars in electricity costs.
A small company like Nichia should do niche products.
For people who currently have to burn fossil fuels to produce meager, polluting light, LED lighting is a game changer.
Basically, I like research because research is like to solve the quiz, you know. Always there is a problem, and I have to solve the problem. So I like those patterns. It's almost like research is sort of in a quiz.
My dream was to work for one of the big electronics companies like Sony or Panasonic.
