Particularly in the last decades of his life, Planck made an effort to transmit the findings of modern science to the general public. This stemmed from Planck's basic convictions about the cultural value of science for mankind-a typical attitude for Planck's generation. He wrote articles for daily newspapers and popular science magazines, gave interviews, and broadcast speeches on radio. But the public lecture became his preferred forum. He went on extended lecture tours throughout Germany and abroad until the year he died. He himself pointed out one motivation for such a busy lecturing schedule: "At my age of 89 I cannot be productive in science anymore: what remains for me is the possibility of reaching out to people in their search for truth and insight, above all young people."
