Physics enthusiast Dianna Cowern, MIT '11, visited Google's office in Cambridge, MA to discuss how a passion for science, a thirst for knowledge and feeling that she did not fit in led to a career in science communication. Dianna Cowern is the creator of YouTube star Physics Girl: http://www.physicsgirl.org/about/ Driving tractors on a farm growing up in Hawaii could not have prepared her for the science and engineering work she would later pursue. She researched dark matter with Prof. Jocelyn Monroe at MIT, and low-metallicity stars with Prof. Anna Frebel at the Harvard-Smithsonian Center for Astrophysics. Eventually, she started exercising the nerdy side of her brain on YouTube as Physics Girl before (and while) heading to UCSD as a science outreach coordinator.
