watched Inexplicable Universe part 1

From the Great Courses catalogue available on Kanopy via the public library, I watched episode 1 of The Inexplicable Universe, entitiled History's Mysteries. It was narrated by Neil deGrasse Tyson. As usual he was ebullient and effective. He did make one mistake though! Huh. I was surprised by that.

I enjoyed the discussion of the "greatest null result," the attempt, with an interferometer, to show the speed of light varied travelling through the luminiferous aether ahead of and trailling the Earth. NDGT said this was a milestone, a shift from practical, observational form of "common-sense" science to one explained by mathematical formulae and tested by experiment.
