  • Use "Who would have thought around 1900 that in fifty years…" in a science discussion, then ask which concrete claim the wording makes.
  • Compare its treatment of thought with around in a lesson, essay, or editorial note before drawing a conclusion.
  • Before sharing it as Einstein's exact words, display the attribution caveat and follow the evidence link recorded on the page.
