Perception Deception

There are many illusions that are known to us that force us to perceive things as different then they really are. (http://visualfunhouse.com/wpcontent/uploads/2009/03/flaming-street-ofchalk.jpg)
The ponzo illusion makes things look smaller the farther away they are. Railroad tracks look as though they run into each other far away but they are really the same distance apart all the way down. They also make the wooden planks between the tracks look shorter and shorter but they are also all the same length all the way down.

There are many real life instances where we perceive things as different then what they really are. It is important for us to know about illusions that effect our real world perception so we know that things aren't always what they seem. These illusions can be especially important with driving. It is important to know how far away things and people are from you. There is that little message in your side mirrors also "objects in mirror are closer then they appear"

which is another way that your perceptions trick you. Things can be close but look further away in the mirror which can be dangerous when driving. This is why it is so important to be aware of illusions that can be tricking you in sometimes dangerous ways. There is also the perception related to the ponzo illusion that people who are further away look smaller than they are. They are still a normal sized person but from a distance a person close to you looks much bigger than them although the two people could be the same or very close to each other in actual size.
