The Moon Illusion

Estimation, Video 14 October 2013 0 Comments

Have you ever looked up at the moon in the night sky only to think that it is bigger than normal?  Is it possible that the moon is actually closer to the Earth on these nights?  If you measure the size of the moon on any given night, it is always the same size.  Our brains can be tricked into thinking that it is bigger on some nights and smaller on others.  For example, when the moon is closer to the horizon, we tend to think that it looks bigger.  When the moon is higher in the sky, it appears smaller.  This phenomenon is referred to as “the moon illusion” and is explained in greater detail in the following video.
