I can't see how this is true. It isn't obvious to me that one could conclude anything from a video like that without a substantial prior knowledge of mathematical physics. Seeing a red, vaguely circular object, move across a screen tells me nothing unless I already know an enormous amount.
He elaborates on the claim a bit in this comment.
And it still doesn't make any sense. Think about the motion of a helium balloon. Think about the motion of a charged particle in a magnetic field. There's literally an infinite number of possible formal mathematical models that could include 12 frames of an apple falling. Thing about how enormous the leap of logic is to go from, "This one thing moved" to "All things must move the way that one thing does." There's quite simply not enough observations and not enough information in seeing something happen once to prove a theory. I feel lik...
I suggested recently that part of the problem with with LW was a lock of discussion posts which was caused by people not thinking of much to post about.
When I ask myself "what might be a good topic for a post?", my mind goes blank, but surely not everything that's worth saying that's related to rationality has been said.
So, is there something at the back of your mind which might be interesting? A topic which got some discussion in an open thread that could be worth pursuing?
