He says he had two mid-life crisis. The first one when he got an idea and the second one when he implemented it. Today he is Nobel Prize laureate - professor Eric Betzig came up with a method that makes is possible to watch throught optical microscopes things that are only few nanometers big. One nanometer equals one bilionth of a meter. Scientist can now for example see proteins responsible for development of Alzheimer’s or Parkinson‘s disease. He was also able to surpass his own recognised research. He recieved the 2014 Nobel Prize in Chemistry and yet he says "I certainly don‘t know any chemistry". www.ceskatelevize.cz/porady/1044129…stry-laureate/
