Goethe Quotes (1 quote)
When I look back to … the long and ever tortuous path which led [to quantum theory], finally, to its disclosure, the whole development seems to me to provide a fresh illustration of the long-since proved saying of Goethe’s that man errs as long as he strives.
From Nobel Prize Lecture (2 Jun 1920), 'The Genesis and Present State of Development of the Quantum Theory', Nobel Lectures, Physics 1901-1921 (1967), and on the nobelprize.org web site. This passage of Planck’s speech is translated very differently by James Murphy in 'Introduction: Max Planck: a Biographical Sketch' to Max Planck (trans.), Where is Science Going (1932), 23. See elsewhere on this web page, beginning, “Looking back…”.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) --
