Moon illusion
- uslic001 14y agoIf you look at the moon on the horizon upside down through your legs the illusion that it is large goes away.
- todd2012 14y agoBack when I was an MIT undergrad in the early 1970's I got a ride back to eastern New York for Thanksgiving or Christmas break with several other MIT students. That evening, the moon appeared very large, and I mentioned it was just an illusion. (I had read the July, 1962 issue of Scientific American growing up and knew about the illusion--it was the cover story.) Try as I might, I could not convince the others in the car that it was an illusion.
