Helen Freedhoff: Helen Sarah Freedhoff (January 9, 1940 – June 10, 2017) was a Canadian theoretical physicist who studied the interaction of light with atoms.  She gained her doctorate at the University of Toronto in 1965 and completed a postdoctoral fellowship at Imperial College in London.  Freedhoff was the first woman appointed as a physics professor at York University in Toronto, and is believed to have been the only woman professor of theoretical physics in Canada at the time.

Jim Al-Khalili: Jameel Sadik "Jim" Al-Khalili OBE (Arabic: جميل صادق الخليلي‎ ‎ ; born 20 September 1962) is a British Iraqi theoretical physicist, author and broadcaster.
