Riddle me this: if the Earth is flat, how can you explain the motion of Focault’s pendulum?
You know they have electric initiators right?

This is a good summary of Foucalt’s Pendulum and what was believed at the time of the experiment from both supporters and skeptics. A fan of Foucault’s work was quite disturbed with the anomalies and inconsistencies of the pendulum’s performance. He went to talk with Professor Humboldt to get his input:
“After seeing the pendulum-experiment here also and, strangely, again with a deviation to the left, I went to Alexander v. Humboldt, who was indeed ever the first refuge of those seeking information. He received me very friendly and spoke the memorable words: I have known, too, for a long time, that as yet we have no proof for the Copernican system, but I shall never dare to be the first to attack it. Don’t rush into the wasps’ nest. You will but bring upon yourself the scorn of the thoughtless multitude.”
