LED

I read a book about the life of Shuji Nakamura, a Japanese Novel Prize winner.                                  
He used to work for a company in the country side of Japan, where he devoted himself into developing LED.       
Later on, he invented the blue-color LED for the first time in the world and contributed to the development of producing different colors of LED.               
At present, he is a Physics professor at Sta. Barbara University in America.
He observed that in America, the facilities pay a good salary to the skillful researchers.
However, researchers in Japan cannot receive a good reward in spite of their efforts.
He insists in the book that researchers should be evaluated based on their contribution to the company or society.
Those evaluation system is required to motivate people for making better products.                        
I learned that evaluation systems in Japan and the U.S. are totally different.
