  • May 19 2011: sean, thanks for your time! just wondering... when two people watch a funny movie they laugh... when they watch a sad movie, they cry... would that count as a repeatable finding for a scientific experiment? would it prove that there is a dimension of emotions?

      May 19 2011: I think you would have to design a more careful scientific protocol than that. It might be possible to think of "emotions" as a dimension, but it's clearly not the same kind of dimension as time and space -- so one could argue that you're just abusing the terminology.

      But emotions are real, and hard to study. Human sciences in general are much more difficult than physics and astronomy.
      • May 19 2011: ah. thx for your response! when i was a little kid, one of my teachers had me read a book called flatland or something... and it said that to find the next dimension, you just had to go "inside yourself" or something like that lol. i guess that's what i've been imagining all these years!
