In the 1940s when Ruby Payne Scott went to university she was the only girl in her class. Back then, you could count the number of female physicists in the entire country on one hand. Ruby was super smart but she struggled to get a job because blokes thought women belonged at home. Not Ruby \u2014 she once used a bent coat hanger, some plugs and a few bits and bobs to tune in to the noises of the galaxy \u2014 something nobody had ever done before. It\u2019s no wonder she went on to become one of Australia\u2019s most outstanding physicists. Narrated by robotics whiz Marita Cheng.
