What is the author's tone in A Beautiful Mind: A Biography of John Forbes Nash, Jr., Winner of the Nobel Prize in Economics, 1994 by Sylvia Nasar?

The author, Sylvia Nasar, writes A Beautiful Mind in an objective tone. Her goal is to tell the story of the life of mathematical genius John Forbes Nash, Jr. and the devastating effects of the illness he suffers. Her approach is to present the facts and to explain them and she does this well in an objective manner. She examines Nash's childhood and finds he was a loner who had problems in social situations. She looks at his behavior in graduate school and in his employment at Massachusetts Institute of Technology and at the RAND Corporation.
