Although intellect and talent were vital to the preeminent scientists of the 20th century, it was ultimately their individual personalities and quirks that drove each to great discoveries. Albert Einstein's youthful self-confidence, Paul Dirac's innate eccentricities, Fred Hoyle's explicit obstinacy, Martin Ryle's shrewd competitiveness, Richard Feynman's love of the unconventional, Jocelyn Bell-Burnell's steadfast doggedness and Stephen Hawking's brilliant conviction are truly responsible for transforming our understanding of life and the universe. Using rare archival footage and interviews dating back to the 1920s, GREAT SCIENTISTS IN THEIR OWN WORDS provides unique insight into the lives and temperaments of some of the world's most brilliant physicists.
