The history of the 20th century is marked by two great narratives: nations locked in savage wars over ideology and territory, and scientists overturning the received wisdom of preceding generations. For Paul Johnson, the modern era begins with one of the second types of revolutions, in 1919, when English astronomer Sir Arthur Eddington translated observations from a solar eclipse into proof of Albert Einstein's general theory of relativity, which turned Newtonian physics on its head. Eddington's research became an international cause célèbre: "No exercise in scientific verification, before or since, has ever attracted so many headlines or become a topic of universal conversation," Johnson writes, and it made Einstein into science's first real folk hero.
