Documentary films for millions of dollars or short videos on Youtube. Two ways to popularize science. Two enthusiastic scientists who go “out there” to convince people that “Science is beautiful. Science is important. Science is for everybody.” The anthropologist Niobe Thompson researches and explains evolution in the documentary series The Great Human Odyssey. The physicist Derek Muller tries to answer everyday life questions through science in short interactive videos on his Youtube channel Veritasium. We shot an interview with both of them at the festival Academia Film in Olomouc.
