Editor's Take:

Karl Popper changed how we think about science. Born in Vienna, he fled the Nazis and taught in New Zealand. He argued that a theory is scientific only if it could be proved false. He called this falsifiability. His book The Open Society and Its Enemies defended democracy. He later taught at the London School of Economics. He was knighted in 1965.
