Vandana Shiva In this documentary, we follow environmental activist and nuclear physicist Vandana Shiva
Shiva studied physics at Panjab University in Chandigarh, graduating as a Bachelor of Science in 1972. After a brief stint at the Bhabha Atomic Research Centre, she moved to Canada to pursue a master's degree in the philosophy of science at the University of Guelph in 1977 where she wrote a thesis entitled "Changes in the concept of periodicity of light". In 1978, she completed and received her PhD in philosophy at the University of Western Ontario, focusing on philosophy of physics. Her dissertation was titled "Hidden variables and locality in quantum theory" in which she discussed the mathematical and philosophical implications of hidden variable theories that fall outside of the purview of Bell's theorem.
