Before leaving the Pantheon and all its treasure, just a quick stop at the Foucault Pendulum . Those of you who know me are aware, I am sure, that physics is not my thing! But David has a deep and profound love of science, so I try to appreciate it and respect his training. This is something that is simple, yet clear. . . . . a theory demonstrated and not just a theory proved through complicated math.
Image the excitement and awe of these people in 1851 as they see a mystery as before unproved , that the earth rotates on its axis.
Well, it is pretty cool today, as well.
Back to the streets of Paris!
