What Do You Care What Other People Think?, Further Adventures of A Curious Character is the story of Richard P. Feynman, who is a world-renowned Physicist and Nobel Laureate in Physics. He also is a physics professor at Cal Tech. Feynman is the author of this book and is also the author of several volumes preceding this book. As such, the book has some gaps in Feynman's life and career that are no doubt covered in other books.

This book briefly covers Feynman's life growing up with a father who has a unique curiosity and unusual methods of looking at the world. Richard's father definitely sparks the mindset necessary for a budding scientist and mathematician. Feynman pays tribute to his mother for her influence on his successful life and career. He learns from her that the highest forms of understanding one can achieve are laughter and human compassion. Although Richard is born and raised in the Jewish faith, his curiosity leads him as a young man to question his faith to the point where he can no longer believe and finally becomes a life-long atheist.

In high school Richard meets his future wife, Arlene. Both sets of parents agree that the couple is too young to marry, but Arlene and Richard remain devoted. Although Richard spends much time away from Arlene while at MIT for undergraduate work and then at Princeton in advanced studies in physics, they stay close and commit to marriage as soon as possible. Sadly, Arlene is stricken with a serious disease from which she never recovers. But since Arlene is the love of Richard's life, he insists on marrying her.

After graduating from Princeton, Richard takes a position with the Manhattan Project, an organization whose mission is to develop the Atomic Bomb. While Richard is working, Arlene is at a hospital nearby in New Jersey. Richard visits as much as possible. When Richard is transferred with the Project to Los Alamos, New Mexico, Arlene is transferred to a hospital in Albuquerque. Arlene does not last very long and dies while Richard is still working on the Manhattan Project.

Subsequently, Richard marries Gweneth and has a happy union with her. They have two children, Michelle and Carl. Richard travels world-wide as a speaker and leader at many Physics and Scientific conferences and seminars. Several years before his death, his country calls upon him for help. Richard's reputation and brilliance proceeds him and leads him to membership on the Presidential Commission investigating the Challenger disaster. Without his natural curiosity, intellect, vast experience and background in physics, the Commission would have been missing its most important member. Richard puts in optimum effort and time in chasing down the cause of the horrible accident. His curiosity leads him to a myriad of puzzle pieces and his intellect allows him to make sense of the complex information with which he is confronted.
