Joan Feynman
From Wikipedia, the free encyclopedia
Joan Feynman (b. 31 March 1928) is an astrophysicist, the sister of Richard Feynman, who made original studies of the interactions between the solar wind and the Earth's magnetosphere. While working at the NASA Ames Research Centre in 1971, Feynman showed that coronal mass ejections could be identified by the presence of helium in the solar wind. She subsequently worked at the National Center for Atmospheric Research in Colorado, and the National Science Foundation. In 1985, she moved to the Jet Propulsion Laboratory. Using data from Explorer 33, she demonstrated that the occurrence of auroras is a product of the interaction of the solar wind with the magnetosphere. In 1999 she was named as one of JPL's elite senior scientists and in 2000 was awarded NASA's Exceptional Achievement Medal. She retired from JPL as a Senior Scientist in 2003. Recently, Joan Feynman co-authored articles demonstrating the influence of solar activity on the climate of the first millennium [1].
Feynman studied at Oberlin College, Syracuse University (PhD, 1958), and Columbia University. She is the sister of the famous, late physicist Richard Feynman. Her son Charles Hirshberg (from her first marriage to Richard Hirshberg) is news editor of Popular Science. She has been married to the astrophysicist Alexander Ruzmaikin since 1987. [1] [2]
